Standard Length = 80 ft. (24.4 m) or less total equivalent length

Applications in this area are long line. Accessories are required as shown recommended on Long Line Application Guidelines

Applications in this area may have height restrictions that limit allowable total equivalent length, when outdoor unit is below indoor unit See Long Line Application Guidelines

REFRIGERANT PIPING LENGTH LIMITATIONSMaximum Line Lengths:The maximum allowable total equivalent length for heat pumps varies depending on the vertical separation. See the tables below for allowable lengthsdepending on whether the outdoor unit is on the same level, above or below the outdoor unit.

LONG LINE APPLICATIONSAn application is considered Long Line when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerantmanagement for systems reliability. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and verticalseparation between the indoor and outdoor units.

For Heat Pump systems, the chart below shows when an application is considered Long Line. Beyond these lengths, long line accessories are required:

PRODUCTSEquipment

— Factory assembled, single piece, air−cooled heat pump unit.Contained within the unit enclosure is all factory wiring,piping, controls, compressor, refrigerant charge R−410A, andspecial features required prior to field start−up.

Unit Cabinet— Unit cabinet will be constructed of galvanized steel,

bonderized, and coated with a powder coat paint.— Available with dense grille only.

Fans— Condenser fan will be direct−drive propeller type, discharging

air upward.— Condenser fan motors will be totally enclosed, 1−phase type

with class B insulation and permanently lubricated bearings.— Shafts will be corrosion resistant.— Fan blades will be statically and dynamically balanced.— Condenser fan openings will be equipped with steel wire

safety guards.Compressor

— Compressor will be hermetically sealed.— Compressor will be mounted on rubber vibration isolators.

Condenser Coil— Condenser coil will be air cooled.— Coil will be constructed of aluminum fins mechanically

bonded to copper tubes which are then cleaned, dehydrated,and sealed.

— ArmorPlate coating − Aluminum fin material is pre−coated onboth sides with a corrosion protective epoxy phenolic coating.

Refrigeration Components— Refrigeration circuit components will include liquid−line

shutoff valve with sweat connections, vapor−line shutoffvalve with sweat connections, system charge of R−410Arefrigerant, POE compressor oil, accumulator, and reversingvalve.

Operating Characteristics— The capacity of the unit will meet or exceed _____ Btuh at a

suction temperature of _____ �F/�C. The power consumptionat full load will not exceed _____ kW.

— Combination of the unit and the evaporator or fan coil unitwill have a total net cooling capacity of _____ Btuh or greaterat conditions of _____ CFM entering air temperature at theevaporator at _____ �F wet bulb and _____ �F/�C dry bulb,and air entering the unit at _____ �F/�C.

— The system will have a SEER of _____ Btuh/watt or greaterat DOE conditions.

Electrical Requirements— Nominal unit electrical characteristics will be _____ v, single

phase, 60 hz. The unit will be capable of satisfactoryoperation within voltage limits of _____ v to _____ v.

— Unit electrical power will be single point connection.— Control circuit will be 24v.

Special Features— Refer to section of this literature identifying accessories and

descriptions for specific features and available enhancements.



SYSTEM DESIGN SUMMARY1. Intended for outdoor installation with free air inlet and outlet.

Outdoor fan external static pressure available is less than 0.01−in.wc.

2. Minimum outdoor operating air temperature without low−ambi-ent operation accessory is 55�F (12.8�C).

3. Maximum outdoor operating air temperature for cooling mode is125�F (51.7�C).

4. Minimum outdoor operating air temperature for heating mode is–30�F (–34.4�C).

5. Maximum outdoor operating air temperature for heating mode is66�F (18.9�C).

6. For reliable operation, unit should be level in all horizontalplanes.

7. For interconnecting refrigerant tube lengths greater than 80 ft(23.4 m) and/or elevation differences between indoor and

outdoor units greater than 20 ft (6.1 m), consult Residential Pip-ing and Longline Guideline and Service Manual available fromequipment distributor.

8. If any refrigerant tubing is buried, provide a 6 in. (152.4 mm)vertical rise to the valve connections at the unit. Refrigeranttubing lengths up to 36 in. (914.4 mm) may be buried withoutfurther consideration. Do not bury refrigerant lines longer than36 in. (914.4 mm).

9. Use only copper wire for electric connection at unit. Aluminumand clad aluminum are not acceptable for the type of connectorprovided.

10. Do not apply capillary tube indoor coils to these units.11. Factory−supplied filter drier must be installed.

Accessory Description and Usage(Listed Alphabetically)

1. Ball−Bearing Fan MotorA fan motor with ball bearings which permits speed reduction whilemaintaining bearing lubrication.

Usage Guideline:Required on all units when using MotorMaster�

2. Compressor Start Assist − Capacitor and RelayStart capacitor and relay gives a hard boost to compressor motor at eachstart up.

Usage Guideline:Required for reciprocating compressors in the following

applications:Long lineLow ambient coolingHard shut off expansion valve on indoor coilLiquid line solenoid on indoor coil

Required for single−phase scroll compressors in the following applications:

Long lineLow ambient cooling

Suggested for all compressors in areas with a history of low voltage problems.3. Compressor Start Assist — PTC TypeSolid state electrical device which gives a soft boost to the compressor ateach start−up.

Usage Guideline:Suggested in installations with marginal power supply.

4. Crankcase HeaterAn electric resistance heater which mounts to the base of the compressorto keep the lubricant warm during off cycles. Improves compressorlubrication on restart and minimizes the chance of liquid slugging.

Usage Guideline:Required in low ambient cooling applications.Required in long line applications.Suggested in all commercial applications.

5. Evaporator Freeze ThermostatAn SPST temperature−actuated switch that stops unit operation whenevaporator reaches freeze−up conditions.

Usage Guideline:Required when low ambient kit has been added.

6. Isolation RelayAn SPDT relay which switches the low−ambient controller out of theoutdoor fan motor circuit when the heat pump switches to heatingmode.

Usage Guideline:

Required in all heat pumps where low ambient kit has been added.

7. Liquid−Line Solenoid Valve (LLS)An electrically operated shutoff valve which stops and starts refrigerantliquid flow in response to compressor operation. It is to be installed atthe outdoor unit to control refrigerant off cycle migration in the heatingmode.

Usage Guideline:An LLS is required in all long line heat pump applications to control refrigerant off cycle migration inthe heating mode. See Long Line Guideline.

8. Low−Ambient Pressure Switch KitA long life pressure switch which is mounted to outdoor unit servicevalve. It is designed to cycle the outdoor fan motor in order to maintainhead pressure within normal operating limits. The control will maintainworking head pressure at low−ambient temperatures down to 0�F(−18�C) when properly installed.

Usage Guideline:A Low−Ambient Pressure Switch or MotorMaster� Low−Ambient Controller must be used when cooling operation is used at outdoor temperatures below 55�F (12.8�C).

9. Outdoor Air Temperature SensorThis device enables the thermostat to display the outdoor temperature.This device also is required to enable special thermostat features such asauxiliary heat lock out or fossil fuel applications.

Usage Guideline:Suggested for all outdoor air temperature sensor supportingthermostats.



10. Sound JacketWraparound sound reducing cover for the compressor. Reduces thesound level by about 2 dBA.

Usage Guideline:Suggested when unit is installed closer than 15 ft. (4.577 m) to quiet areas, bedrooms, etc.Suggested when unit is installed between two houses less than 10 ft. (3.05 m) apart.

11. Thermostatic Expansion Valve (TXV) Bi−FlowA modulating flow−control valve which meters refrigerant liquid flowrate into the evaporator in response to the superheat of the refrigerantgas leaving the evaporator.

Usage Guideline:Accessory required to meet AHRI rating and system reliability, where indoor not equipped.Required in all heat pump applications designed with R−410A refrigerant.
