5. The maximum allowable line length for this product is 75 feet.
SECTION III: UNIT INSTALLATIONLOCATIONBefore starting the installation, the suitability of the locations for boththe indoor and outdoor units need to be checked. All required limitationsand clearances must be observed. The outdoor unit must have suffi-cient clearance for air entrance to the condenser coil, for air discharge,and for service access as shown in Figure 1.
If the unit is to be installed on a hot sun exposed roof or a paved groundarea that is seasonally hot, the unit should be raised sufficiently abovethe roof or ground to avoid taking the accumulated layer of hot air intothe outdoor unit.
Provide adequate structural support.
ADD-ON REPLACEMENT/RETROFITWhen this unit is being used as a replacement for an R-22 unit, it isrequired that the outdoor unit, indoor coil, and metering device all bereplaced. The following steps should be performed in order to insureproper system operation and performance. Line-set change out is alsorecommended.
1. Change-out of the indoor coil to an approved R-410A coil/ condens-ing unit combination with the appropriate metering device.
2. Change-out of the line-set when replacing an R-22 unit with anR410-A unit is highly recommended to reduce cross-contaminationof oils and refrigerants.
3. If change-out of the line set is not practical, then the following pre-cautions should be taken.• Inspect the line set for kinks, sharp bends, or other restrictions,
and for corrosion.• Determine if there are any low spots in the line set which might
cause oil traps. • Flush the line set with a commercially available flush kit to
remove as much of the existing oil and contaminants as possi-ble.
• Install a suction line filter-drier to trap any remaining contami-nants, and remove it after 50 hours of operation.
4. If the outdoor unit is being replaced due to a compressor burnout,then installation of a 100% activated alumina suction-line filter drierin the suction-line is required, in addition to the factory installed liq-uid-line drier. Operate the system for 10 hours. Monitor the suctiondrier pressure drop. If the pressure drop exceeds 3 psig, replaceboth the suction-line and liquid-line driers. After a total of 10 hoursrun time where the suction-line pressure drop has not exceeded 3psig, replace the liquid line drier, and remove the suction-line drier.During the contamination removal procedure, never leave a suctionline drier in the system longer than 50 hours of run time.

GROUND INSTALLATIONThe unit may be installed at ground level on a solid base that will notshift or settle, causing strain on the refrigerant lines and possible leaks.The unit must be installed in as level a position as possible while main-taining the clearances shown in Figure 1.
Normal operating sound levels may be objectionable if the unit is placeddirectly under windows of certain rooms (bedrooms, study, etc.).
Condensate will drain from beneath the coil of the outdoor unit duringthe defrost cycle. Normally this condensate may be allowed to draindirectly on the ground.
1. Elevate the unit sufficiently to prevent any blockage of the airentrances by snow in areas where there will be snow accumulation.
2. Check the local weather bureau for the expected snow accumula-tion in your area.
3. Isolate the unit from rain gutters to avoid any possible wash out ofthe foundation.
ROOF INSTALLATIONWhen installing units on a roof, the structure must be capable of sup-porting the total weight of the unit, including a pad, lintels, rails, or anycomponents used to minimize the transmission of sound or vibrationinto the conditioned space.
WALL MOUNT INSTALLATIONCare must be taken to mount the outdoor unit on a solid base that issloped to shed water, secure from settlement, and is isolated from thestructural foundation or walls to prevent sound and vibration transmis-sion into the living space. In addition heat pump units must be elevatedabove anticipated snow accumulation levels to allow for proper defrostdrainage and airflow.
On occasion, site conditions may require direct wall mounted bracketsto be used to locate and support the outdoor unit. In these applications,care must be taken to address unit base pan support, structural integ-rity, safe access and serviceability, as well as the possible sound andvibration transmission into the structure. These applications are bestserved by a properly engineered solution.
UNIT PLACEMENT
1. Provide a base in the pre-determined location.2. Remove the shipping carton and inspect for possible damage.3. Compressor tie-down bolts should remain tightened.4. Position the unit on the base provided.
LIQUID LINE FILTER-DRIERThe heat pumps have a solid core bi-flow filter/dryer located on the liq-uid line.
PIPING CONNECTIONS
The outdoor unit must be connected to the indoor coil using field sup-plied refrigerant grade copper tubing that is internally clean and dry.Units should be installed only with the tubing sizes for approved systemcombinations as specified in Tabular Data Sheet. The charge given isapplicable for total tubing lengths up to 15 feet. See Application DataPart Number 247077 for installing tubing of longer lengths and elevationdifferences.
PRECAUTIONS DURING LINE INSTALLATION1. Install the lines with as few bends as possible. Make sure there is no
damage done to the couplings nor kink made in the tubing. Useclean hard drawn copper tubing where no appreciable amount ofbending around obstruction is necessary. If soft copper must beused, make sure to avoid sharp bends which may cause a restric-tion.
2. Ensure that the lines are installed so they do not obstruct serviceaccess to the coil, air handling system, or filter.
3. Make sure to isolate the refrigerant lines to minimize noise transmis-sion from the equipment to the structure.
4. Make sure to insulate the vapor line with a minimum of 3/8” foamrubber insulation (Armaflex or equivalent). Make sure to insulate theliquid lines which are exposed to direct sunlight and/or high temper-atures.
5. Tape and suspend the refrigerant lines as shown. DO NOT allowtube metal-to-metal contact. See Figure 2.
6. Use PVC piping as a conduit for all underground installations asshown in Figure 3. Keep buried lines as short as possible to mini-mize the build up of liquid refrigerant in the vapor line during longperiods of shutdown.
WARNINGThe outdoor unit should not be installed in an area where mud or icecould cause personal injury. Remember that condensate will drip fromthe unit coil during heat and defrost cycles and that this condensatewill freeze when the temperature of the outdoor air is below 32°F.
NOTICEHeat pumps will defrost periodically resulting in water drainage. Theunit should not be located where water drainage may freeze and cre-ate a hazardous condition - such as sidewalks and steps.
CAUTIONFailure to use the same as the original factory drier, or using a substi-tute drier, or using a granular type drier may result in damage to theequipment.
!
!
NOTICEReplacements for the liquid line drier must be exactly the same asmarked on the original factory drier. See Source 1 for O.E.M. replace-ment driers.
Filter-Drier Source 1 Part No. Apply with ModelsS1-404101 All Sizes
WARNINGNever install a suction-line filter drier in the liquid line of an R-410Asystem. Failure to follow this warning can cause a fire, injury or death.
CAUTIONThis system uses R-410A refrigerant only, which operates at higherpressures than R-22. No other refrigerant than R-410A may be usedin this system. Gauge sets, hoses, refrigerant containers, and recov-ery system must be designed to handle R-410A. If you are unsure,consult the equipment manufacturer.
NOTICEUsing a larger than specified line size could result in oil return prob-lems. Using too small a line will result in loss of capacity and otherproblems caused by insufficient refrigerant flow. Slope horizontalvapor lines at least 1" every 20 feet toward the outdoor unit to facili-tate proper oil return.

7. Pack fiberglass insulation and a sealing material such as permagumaround refrigerant lines where they penetrate a wall to reduce vibra-tion and to retain some flexibility.
8. See Form 247077 for additional piping information.
PRECAUTIONS DURING BRAZING OF LINESAll outdoor unit and evaporator coil connections are copper-to-copperand should be brazed with a phosphorous-copper alloy material suchas Silfos-5 or equivalent. DO NOT use soft solder. The outdoor unitshave reusable service valves on both the liquid and vapor connections.The total system refrigerant charge is retained within the outdoor unitduring shipping and installation. The reusable service valves are pro-vided to evacuate and charge per this instruction.
Serious service problems can be avoided by taking adequate precau-tions to assure an internally clean and dry system.
PRECAUTIONS DURING BRAZING SERVICE VALVEWrap a wet rag around the service valve as shown in Figure 4 to pre-vent heat damage. Also, protect all painted surfaces, insulation, andplastic base during brazing. After brazing, cool joint with wet rag.
Valve can be opened by removing the plunger cap and fully inserting ahex wrench into the stem and backing out counter-clockwise until valvestem just touches the chamfered retaining wall.
Connect the refrigerant lines using the following procedure:1. Remove the cap and Schrader core from both the liquid and vapor
service valve ports at the outdoor unit. Connect low pressure nitro-gen to the liquid line service port.
2. Braze the liquid line to the liquid valve at the outdoor unit. Be sure towrap the valve body with a wet rag. Allow the nitrogen to continueflowing. Refer to the Tabular Data Sheet for proper liquid line sizing.
3. Go to “SECTION IV” for TXV installation.
4. Braze the liquid line to the evaporator liquid connection. Nitrogenshould be flowing through the evaporator coil.
5. Remove the split rubber grommet from the vapor connection at theindoor coil. Braze the vapor line to the evaporator vapor connection.After the connection has cooled, place the rubber grommet back intothe mounting position. Refer to the Tabular Data Sheet for propervapor line sizing.
6. Protect the vapor valve with a wet rag and braze the vapor line con-nection to the outdoor unit. The nitrogen flow should be exiting thesystem from the vapor service port connection. After this connectionhas cooled, remove the nitrogen source from the liquid fitting serviceport.
7. Replace the Schrader core in the liquid and vapor valves.
8. Leak test and repair leaks in all refrigerant piping connections includ-ing the service port flare caps. DO NOT OVERTIGHTEN caps.Torque caps between 40 and 60 inch - lbs. maximum.
9. Evacuate the vapor line, the evaporator, and the liquid line to 500microns or less in accordance with the EVACUTATION procedures.
FIGURE 2: Tubing Hanger
FIGURE 3: Underground Installation
CAUTIONDry nitrogen should always be supplied through the tubing while it isbeing brazed, because the temperature required is high enough tocause oxidation of the copper unless an inert atmosphere is provided.The flow of dry nitrogen should continue until the joint has cooled.Always use a pressure regulator and safety valve to insure that onlylow pressure dry nitrogen is introduced into the tubing. Only a smallflow is necessary to displace air and prevent oxidation.
WARNINGThis is not a backseating valve. The service access port has a valvecore. Opening or closing valve does not close service access port. If the valve stem is backed out past the chamfered retaining wall, theO-ring can be damaged causing leakage or system pressure couldforce the valve stem out of the valve body possibly causing personalinjury.

FIGURE 4: Heat Protection
CAUTIONDo not install any coil in a furnace which is to be operated during the heat-ing season without attaching the refrigerant lines to the coil. The coil isunder 30 to 35 psig inert gas pressure which must be released beforebrazing lines to prevent excessive pressure build-up and possible coildamage.
WARNINGNever attempt to repair any brazed connections while the system is underpressure. Personal injury could result.
WARNINGRefrigeration piping and indoor coil can be pressurized to 250 psig withdry nitrogen and leak tested with a bubble type leak detector. Thenrelease the nitrogen charge.Do not use the system refrigerant from the outdoor unit to purge or leaktest the system.

10.Release the refrigerant charge into the system in accordance withthe SYSTEM CHARGE procedures. Open the liquid line base valvefirst and let pressures equalize. Then, open the suction line basevalve. When opening either valve, use an appropriate hex headwrench and back seat the base valve by turning it counter clockwiseuntil it stops against the chamfered retaining wall, and then turn itback 1/8 turn. If the service valve is a ball valve, use an adjustableend wrench to turn valve stem one-quarter turn counterclockwise toopen. Do not overturn (or the valve stem may break or become dam-aged).
11.To prevent leaks, replace base valve caps finger tight, and thentighten the cap an additional 1/12 turn (1/2 hex flat).
12.Replace cap on service ports. Do not remove the flare caps from theservice ports except when necessary for servicing the system.
13. See “System Charge” section for checking and recording systemcharge.
SECTION IV: INDOOR EXPANSION DEVICETHERMOSTATIC EXPANSION VALVE (TXV) INSTAL-LATIONSBefore accomplishing the following procedures, verify the proper TXVkit to be installed on the coil distributor. Refer to supplied Tabular DataSheet for proper indoor coil match up and specific TXV kit.
For installations requiring a TXV, the following are the basic steps forinstallation. For detailed instructions, refer to the Installation Instructionsaccompanying the TXV kit.
Install TXV kit as follows:
1. Relieve nitrogen holding charge from the indoor coil by depressingthe Schrader valve stem located in the end of the suction line. Afternitrogen holding charge is completely discharged, cut the spundowncopper to allow installation of the suction line.
2. Slide indoor coil out of cabinet far enough to gain access to equal-izer fitting on the suction line.
3. Before the suction line from the outdoor unit is brazed to the indoorcoil suction line, remove and discard black plastic cap from equalizerfitting on the indoor coil suction line.
4. Loosen and remove distributor cap seal.
5. Install the TXV to the distributor assembly by hand tightening, andthen turn fitting an additional 1/4 turn to seal. Do not overtighten fit-tings.
6. Install the liquid line to the top of the TXV using the liquid line fittingwhich is supplied with the indoor coil. Hand modify the liquid line toalign with casing opening. Hand tighten the liquid line on the TXV,and tighten an additional 1/4 turn to seal.
7. Install the TXV liquid equalizer line onto the equalizer fitting of thesuction line. Hand tighten the 1/4” SAE nut to the equalizer fitting,and tighten an additional 1/3 turn to seal.
8. Install the TXV bulb to the suction line near the equalizer line, usingthe bulb clamp(s) furnished with the TXV assembly kit. Ensure thebulb is making maximum contact. Refer to TXV kit installationinstructions for view of bulb location.
a. Install the bulb on the suction line near the equalizer line withthe bulb horizontal to the suction line. On a suction line under7/8” Outside Diameter (O.D.), install the bulb on top of theline. On a suction line 7/8” O.D. or larger, install the bulb atabout the 2 or 10 o'clock position.
b. If bulb must be installed vertically to the suction line, positionthe bulb at least 16 inches (40.6 cm) from any bend and onthe opposite side of the bend plane. Positioned the bulb withthe bulb tail at the top, so that the bulb acts as a reservoir.
c. Use thermal insulation provided to protect the bulb from theeffect of the surrounding ambient temperature. Cover thebulb completely to insulate from air-stream.
9. Leak test system after outdoor unit is connected.
10.Slide indoor coil back into cabinet.
CAUTIONDo not connect manifold gauges unless trouble is suspected. Approxi-mately 3/4 ounce of refrigerant will be lost each time a standard manifoldgauge is connected.
CAUTIONIn all cases, mount the TXV bulb after vapor line is brazed and hashad sufficient time to cool.
CAUTIONDry nitrogen should always be supplied through the tubing while it isbeing brazed, because the temperature required is high enough tocause oxidation of the copper unless an inert atmosphere is provided.The flow of dry nitrogen should continue until the joint has cooled.Always use a pressure regulator and safety valve to insure that onlylow pressure dry nitrogen is introduced into the tubing. Only a smallflow is necessary to displace air and prevent oxidation.
NOTICEAll connections to be brazed are copper-to-copper and should bebrazed with a phosphorous-copper alloy material such as Silfos-5 orequivalent. Soft solder is NOT to be used.

SECTION V: EVACUATIONDuring this process, it is necessary to evacuate the system to 500microns or less. If a leak is suspected, a dry nitrogen charge is used tolocate leak(s). After repairing any leaks, another leak test is to be per-formed.
To verify that the system has no leaks, the system is held under a vac-uum by closing the valve to the vacuum pump suction isolating thepump. The micron gauge is observed for a few minutes. If the microngauge indicates a steady and continuous rise, it is an indication of aleak. If the gauge shows a rise, then levels off after a few minutes andremains fairly constant above 500 microns, it is an indication that thesystem is leak free but still contains moisture and may require furtherevacuation. Proper system evacuation requires the micron gauge toindicate a vacuum holding below 500 microns for several minutes.
SECTION VI: SYSTEM CHARGE
To ensure that your unit performs at the published levels, it is importantthat the indoor airflow is determined and refrigerant charge addedaccordingly.
MEASURE INDOOR AIR FLOWTo determine rated air flow for a specific match, consult the technical lit-erature at www.upgnet.com. When attempting to match this air flow,select the lowest possible speed tap, measure the actual flow, andadjust as necessary.
To measure actual air flow, it is not an acceptable method to justcheck the jumper pin setting tables and to assume 0.5” static pres-sure drop.To determine indoor air flow, first measure the static pressure with amanometer between the filter and blower. On a single-piece air handler,take a second reading after the coil. On a furnace or modular air han-dler, take the second reading after the heat exchanger, but before theindoor coil. Add the negative return static to the positive supply static todetermine the system total static pressure. Treat the negative returnstatic as a positive pressure (even though it is a negative reading). Ifthere is static pressure on the blower (i.e. -.10) return, add it to a supplystatic (.40) which equals a (.50) total system static pressure. Comparethis value to the table for the indoor unit's static pressure vs. CFM or toa curve chart.
CHARGING THE UNIT
The factory charge in the outdoor unit includes enough charge for theunit, 15 ft. (4.6 m) of refrigerant piping, and the smallest indoor coil/airhandler match-up. Some indoor coil/air handler matches may requireadditional charge.
See Tabular Data Sheet provided in unit Customer Booklet for chargerequirements.
The “TOTAL SYSTEM CHARGE” must be permanently marked on theunit data plate.
TOTAL SYSTEM CHARGE DETERMINED 1. Determine outdoor unit charge from tabular data sheet.2. Determine indoor coil adjustment from tabular data sheet.3. Calculate the line charge for refrigerant piping using the tabular data
sheet if line length is greater than 15 feet (4.6 m).4. Total system charge = item 1 + item 2 + item 3.5. Permanently stamp or mark the unit data plate with the total amount
of refrigerant in the system.
CHARGING IN COOLING MODEThe unit includes cooling charging chart. All units include a subcooling charging chart for cooling. If a charging chart is not on the unit, then it can be obtained at www.upgnet.com.Cooling charts should not be used to charge the unit. They are ref-erence charts for servicing the unit. After the unit has been serviced, collect the charge and weigh itback in according to the directions.When charging a unit in cooling mode, the charge MUST be weighed in.Charging by any other method, such as superheat, subcooling, coolingcharging charts, feeling the line set, etc is not acceptable. Most heatpumps are sensitive to charge in heating, requiring more charge, socharging by an unacceptable method will cause the unit to performpoorly in heating mode.
CAUTIONRefrigerant charging should only be carried out by a qualified air con-ditioning contractor.
CAUTIONR-410A refrigerant cylinders are rose colored. Always charge thesystem slowly with liquid R-410A refrigerant.
CAUTIONCompressor damage will occur if system is improperly charged. Onnew system installations, charge system per tabular data sheet forthe matched coil and follow guidelines in this instruction.
!
!
!
CAUTIONDo not leave the system open to the atmosphere. Unit damage couldoccur due to moisture being absorbed by the POE oil in the system.This type of oil is highly susceptible to moisture absorption.
WARNINGDO NOT attempt to pump “Total System Charge” into outdoor unit formaintenance or service. This may cause damage to the compressorand/or other components. Recover and weigh “System Charge” intoan appropriate recovery cylinder for any instances requiring evacua-tion.
CAUTIONIT IS UNLAWFUL TO KNOWINGLY VENT, RELEASE OR DIS-CHARGE REFRIGERANT INTO THE OPEN AIR DURING REPAIR,SERVICE, MAINTENANCE OR THE FINAL DISPOSAL OF THISUNIT.
NOTICEThis method is for systems that only have interconnecting lines. Ifany other objects that adjust the charge levels are placed betweenthe indoor and outdoor units (example: a refrigerant flow meter), thenbefore adding charge, the device must first be removed. Follow thesteps above. Run the system in both cooling and heating mode andrecord the high side pressure in each mode. Then insert the deviceand charge the system by matching the same high side pressure inboth heating and cooling as that value recorded without the device. Itis not acceptable to add a pre-determined charge amount listed bythe device manufacturer nor is it acceptable to use any othermethod.

CHARGING IN HEATING MODEIf charging in heating mode, there are two methods for charging:Weighing in the charge is the best method for ensuring the unit per-forms as rated. However, if a device is installed in the line set that altersthe amount of refrigerant, such as a refrigerant flow meter, then the bet-ter method for charging is to match the liquid pressure from the heatingcharging chart (if available) or heating service data (available fromwwwupgnet.com). If no such device exists in the line set, then themethod is acceptable if weighing in the charge is not an option.
If servicing a unit for low heating performance and you find that youhave to add a significant amount of charge (ex: 20-30 ounces) in orderto match the published liquid pressures, the unit will NOT be over-charged in cooling. Heat pumps are sensitive to charge in heating, butnot in cooling.
CHARGING WITH GAUGES
Do not charge a heat pump in cooling mode with gauges or chargingcharts or any other method other than weighing in the charge.
However for servicing a heat pump unit, the charging charts are anacceptable troubleshooting method, but when the servicing is com-pleted, the charge should be reclaimed and weighed in (to guaranteeoptimal performance in heating mode). If servicing in heating mode, thecharge does not have to be reclaimed if the liquid pressures match thepublished values.
Before measuring the pressures, use the method above to check the airflow and then consult the table and match the liquid pressure to that airflow.
Before servicing a unit, confirm that the gauges are accurate by comparing the gauges against a calibrated pressure gauge that has been calibrated against a national standard. If a calibrated pressure gauge is not available, place a R-410A virgin refrigerant container in a conditioned space long enough to come to temperature equilibrium with the surroundings. Then measure the temperature of the air and the pressure of the refrigerant and compare it to the following table::
If the gauges are correct, then measure the pressures using both the cooling and heating charts.

DEHUMIDIFICATION CONTROL (Typical)The indoor unit Installation Manual instructions for the air handler or fur-nace describe the interface with the outdoor heat pump. A dehumidifi-cation control accessory 2HU16700124 may be used with variablespeed air handlers or furnaces in high humidity areas. This control
works with the variable speed indoor unit to provide cooling at areduced air flow, lowering evaporator temperature and increasing latentcapacity. The humidistat in this control opens the humidistat contacts asthe humidity rise. Installation instructions are packaged with the acces-sory. (Also see Figures 10 - 20). Prior to the installation of the dehumid-ification control, the humidistat jumper must be set to ‘YES” on theindoor variable speed air handler or furnace control board.
During cooling, if the relative humidity in the space is higher than thedesired set point of the dehumidification control, the variable speedblower motor will operate at lower speed until the dehumidification con-trol is satisfied. A 40-60% relative humidity level is recommended toachieve optimum comfort.
If a dehumidification control is installed, it is recommended that a mini-mum air flow of 325 cfm/ton be supplied at all times.
To see connection diagrams of all UPG equipment, the “Low VoltageSystem Wiring” document is available online at www.upgnet.com in theProduct Catalog Section.
INDOOR CUBIC FEET PER MINUTE (CFM) CONFIGU-RATION (Typical)For proper system operation, the indoor CFM must be set properly.
Refer to the Technical Guide of the outdoor unit for the recommendedair flow settings of each size condensing unit and matching indoor unit.
Set the cooling speed per the instructions for the air handler or furnace.Verify the airflow.
If installed as a communicating system (outdoor, indoor, and thermo-stat), the system will automatically adjust to the optimal airflow settings.These parameters can also be modified using the Touch Screen Com-munication Control. Refer to the Touch Screen Communication Controlowner’s manual for this procedure. Manual setting of the airflow jump-ers on the indoor equipment is not necessary with the Touch ScreenCommunication Control.
IMPORTANTDo not place more than one wire under any single communicationterminal screw (there are four communication terminal screws). Ifmore than one wire must be connected to a terminal screw, attachonly the terminal end of a one wire pigtail no longer than 6“, anduse a wire connector to connect the other end of the pigtail to theother wires. Failure to do this will result in nuisance communicationerror faults. See Figure 9.

SECTION VIII: SYSTEM START-UPENERGIZE CRANKCASE HEATERIn order to energize the crankcase heater, set the indoor cooling ther-mostat to the OFF position. Close the line power disconnect to the unit.
WITH POWER TO UNIT AND THERMOSTAT IN COOLING POSITION:
1. In the cooling cycle, discharge gas is pumped to the outdoor coilwhich is the condenser. The indoor coil is the evaporator.
2. If fan switch is in ON position, a circuit is made through blower relayto provide continuous blower operation.
3. With fan switch in AUTO position, a circuit is made from thermostatcooling contact through blower relay to provide blower operation.
4. System will cycle with thermostat demand to provide cooling asneeded.
SECTION IX: SYSTEM OPERATIONFor more information on the control operation, refer to the “OPERA-TION INSTRUCTIONS - DEMAND DEFROST CONTROL BOARD”publication.
REQUIRED CONTROL SETUP
1. Consult system wiring diagram to determine proper thermostat wir-ing for your system.
2. If hot heat pump configuration is desired, change HOT HEAT PUMPjumper to ON position. This setting MUST be set on the defrostboard.
3. If installation includes a fossil fuel furnace, change FUEL jumper toON position. This setting MUST be set on the defrost board.
4. Set low temperature cutout (LTCO), balance point (BP), switch point(SP), and Y2 Lock jumpers as desired. These settings may be mod-ified by communicating thermostat.
5. Verify proper system functionality. Confirm room thermostat opera-tion including fault code display capability.
6. Upon completion of installation, verify that no fault codes are storedin memory. Clear the fault code memory if necessary.
DEFROST OPERATIONThe following defrost curve selection jumper positions are set from fac-tory.
NOTE: For information on the 5 & 6 pins, refer to the “Operation Instructions - Demand Defrost Control Board” publication.
IMPORTANTAn attempt to start the compressor without at least 8 hours of crank-case heat will damage the compressor.
IMPORTANTThe following steps must be taken at the time of installation to insureproper system operation.

SECTION X: INSTRUCTING THE OWNERAssist owner with processing warranty cards and/or online registration.Review Owners Guide and provide a copy to the owner and guidanceon proper operation and maintenance. Instruct the owner or the opera-tor how to start, stop and adjust temperature setting.
When applicable, instruct the owner that the compressor is equippedwith a crankcase heater to prevent the migration of refrigerant to thecompressor during the “OFF” cycle. The heater is energized only whenthe unit is not running. If the main switch is disconnected for long peri-ods of shut down, do not attempt to start the unit until 8 hours after theswitch has been connected. This will allow sufficient time for all liquidrefrigerant to be driven out of the compressor.
The installer should also instruct the owner on proper operation andmaintenance of all other system components.
MAINTENANCE1. Dirt should not be allowed to accumulate on the outdoor coils or
other parts in the air circuit. Clean as often as necessary to keep theunit clean. Use a brush, vacuum cleaner attachment, or other suit-able means.
2. The outdoor fan motor is permanently lubricated and does notrequire periodic oiling.
3. If the coil needs to be cleaned, it should be washed with CalgonCoilclean (mix one part Coilclean to seven parts water). Allow solu-tion to remain on coil for 30 minutes before rinsing with clean water.Solution should not be permitted to come in contact with paintedsurfaces.
4. Refer to the furnace or air handler instructions for filter and blowermotor maintenance.
5. The indoor coil and drain pan should be inspected and cleaned reg-ularly to prevent odors and assure proper drainage.
SUBCOOLING CHARGE TABLE IS ON THE CORNER POSTOF THE OUTDOOR UNIT.
CAUTIONIT IS UNLAWFUL TO KNOWINGLY VENT, RELEASE OR DIS-CHARGE REFRIGERANT INTO THE OPEN AIR DURING REPAIR,SERVICE, MAINTENANCE OR THE FINAL DISPOSAL OF THISUNIT.
