5.0 Typical Installation

(Primarily for homes with radiant hotwater or electric baseboard heating. See figure 1.)

Moist, stale air is exhausted from the highhumidity areas in the home, such as bathrooms,kitchen and laundry room. Fresh air is suppliedto bedrooms and principal living areas.

The use of bathroom fans and a range hood issuggested to better exhaust stale air.

Homes with more than one level require atleast one exhaust register at the highest level.

5.1 FULLY DUCTED SYSTEM

There are three (3) common installation methods.

VH0024 figure 1See 6.5.1 for details

5.2 EXHAUST DUCTED SYSTEM (SOURCE POINT VENTILATION)(For homes with forced air heating. See figure 2.)

Moist, stale air is exhausted from the highhumidity areas in the home, such as bathrooms,kitchen and laundry room. Fresh air is supplied tothe cold air return or the supply duct of the furnace.

The use of bathroom fans and a range hood issuggested to better exhaust stale air.

Homes with more than one level require at leastone exhaust register at the highest level.NOTE: For this type of installation, it is not essential

that the furnace blower runs when the unitis in operation, but we recommend it.

VH0025See 6.5.2 for detailsfigure 2

5.3 SIMPLIFIED (VOLUME VENTILATION)(For homes with forced air heating. See figure 3 or 4.)

Fresh air and exhaust air flow through the furnace ducts wich simplifies the installation.

The use of bathroom fans and a range hood is suggested to better exhaust stale air.NOTE: For the installation type shown in figure 4, furnace blower should be running when the

unit is in operation.

6.0 Installation

6.1 ADJUSTING THE DAMPER ROD (FOR ERVS INSTALLED IN WARM REGIONS)Refer to Section 4.2 and observe the difference in the damperposition at the right in diagrams Defrost Mode 1 and Defrost Mode 2:for Defrost Mode 1 the damper is completely closed, whereas for Defrost Mode 2 the damper is half closed. At the factory, all ERVsare assembled for defrost Mode 2. Therefore, if your installation is for an ERV in a warm region (zone D as defined in Section 3),the rod must be moved to position 1 (see figure 5).

NOTE: Before attempting to change the position of the damperrod, place the unit on a table for easy access and removethe recovery core.

6.2 LOCATING AND MOUNTING THE UNIT

Choose an appropriate location for the unit:

• Within an area of the house where the temperature is above10°C / 50°F (basement, attic, furnace room, laundry room, etc.).

• Away from living areas (dining room, living room, bedroom), ifpossible.

• So as to provide easy access to the interior cabinet andto the control panel on the right hand side of the unit.

• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit.

• Close to a drain. If no drain is close by, use a pail to collectrun-off.

• Away from hot chimneys, electrical panel and other firehazards.

• Allow for a power source (110 V standard outlet).

Hang the unit to ceiling joists with the 4 chains andsprings provided (see figures 6 and 7).

6.0 Installation (cont’d)

a) Follow the instructions in Section 6.4 below to determine the appropriate duct diameters foryour system.

b) Keep it simple. Plan for a minimum number of bends and joints. Keep the length of insulatedduct to a minimum.

c) Do not use wall cavities as ducts. Do not use branch lines smaller than 4” (102 mm) Ø.d) Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a

dryer or a range hood. This would cause clogging of the recovery module. Use sheet metal forthe kitchen exhaust duct.

e) Be sure to plan for at least one exhaust register on the highest lived-in level of the house if ithas 2 floors or more.

Use the table below to ensure that the ducts you intend to install will be carrying airflows at or under the recommended values. Avoid installing ducts that will have to carryair flows near the maximum values and never install a duct if its air flow exceeds themaximum value.

NOTE: Examples 6.4.1 and 6.4.2 use imperial measures. The same calculation applies to metric measures.

6.4.1 Example of calculation:

Problem: My installation requires two exhaust registers (one for the kitchen, one for thebathroom). I will connect these registers to a main duct which will connect to the unit (highspeed performance value of 140 cfm). What size of duct should I use for the main exhaustduct and for the two end branches leading to the registers? (See figure 8.)

Solution: Simplified method. (For a more detailed method of calculating duct size refer tothe ASHRAE or HRAI HANDBOOK).

Main duct: Table above indicates a 6” Ø duct: recommended air flow: 120 cfm; maximumair flow: 180 cfm. The high speed air flow of 140 cfm is close enough to the recommendedvalue (120) and far enough away from the maximum value (180). Therefore a 6”Ø duct orlarger is an appropriate choice for the main exhaust duct.

End branches: Each end branch will have to transport an air flow of 70 cfm (140 divided by 2).Table above indicates a 5”Ø duct: recommended air flow: 75 cfm; maximum air flow: 110 cfm.The high speed air flow of 70 cfm is close enough to the recommended value (75) and farenough away from the maximum value (110). Therefore a 5”Ø duct or larger is an appropriatechoice for the 2 end branches.

N.B.: A 4”Ø duct would have been too small because the maximum acceptable value for a4”Ø duct is 60 cfm.

6.5.1 Fully Ducted System (as illustrated in Section 5.1)

Stale air exhaust ductwork:

• Install registers in areas where contaminants are produced: kitchen, bathrooms, laundry room, etc.

• Install registers 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall ORinstall them in the ceiling.

• Install the kitchen register at least 4 feet (1.2 m) from the range top.• If possible, measure the velocity of the air flowing through the registers. If the velocity

is higher than 400 ft/min. (122 m/min), then the register type is too small. Replace witha larger one.

Fresh air distribution ductwork:

• Install registers in bedrooms, dining room, living room and basement.• Install registers either in the ceiling or high on the walls with air flow directed

towards the ceiling. (The cooler air will then cross the upper part of the room, andmix with room air before descending to occupant level.)

• If a register must be floor installed, direct the air flow up the wall.

6.5 INSTALLING THE DUCTWORK AND REGISTERS

WARNINGNever install a stale air exhaust register in a room where a combustion device is, suchas a gas furnace, a gas water heater or a fireplace.

6.5.2 Exhaust Ducted System (Source Point Ventilation) (as illustrated in Section 5.2)

Stale air exhaust ductwork: (same as for Fully Ducted System, described on page 17)

Fresh air distribution:There are two methods for connecting the unit to the furnace:

Method 1: supply side connection• Cut an opening into the furnace supply duct at least

18 inches (0.5 m) from the furnace.• Connect this opening to the fresh air distribution port

of the HRV/ERV (use steel duct, see figure 10).• Make sure that the HRV/ERV duct forms an elbow

inside the furnace ductwork.• If desired, interlock (synchronize) the furnace blower

operation with the HRV/ERV operation. (See Section 8.4).

Method 2: return side connection• Cut an opening into the furnace return duct

at least 6 feet (1.8 m) from the furnace or at a minimum distance of 10 linear feet upstream(from furnace drop).

• Connect this opening to the fresh air distributionport of the HRV/ERV (see figure 11).

NOTE: For Method 2, it is not essential that the furnaceblower runs when the HRV/ERV is in operation,but we recommend it. If desired, synchronize the furnace blower operation (see Section 8.4).

Insulated flexible duct

Use the following procedure for connecting the insulated flexible duct to the ports on the unit(exhaust to outside and fresh air from outside).

a) Pull back the insulation to expose the flexible duct.b) Connect the interior flexible duct to the port using a duct tie.c) Carefully seal the connection with duct tape.d) Pull the insulation over the joint and tuck it between the inner and outer rings of the double collar.e) Pull the vapor barrier over the insulation and over the outer ring of the double collar.f) Apply duct tape to the joint making an airtight seal. Avoid compressing the insulation when you

pull the tape tightly around the joint. Compressed insulation loses its R value and causes waterdripping due to condensation on the exterior surface of the duct.

a) b) c) d), e) f)

Rigid duct:Use duct tape to connect the rigid ducts to the ports.

Make sure that the 2 balancing dampers are left in a fully open position before connecting the ductsto these ports (fresh air distribution port and stale air exhaust port as shown on figure 14).

Humidity Control

Designed primarily for use with our low price HRV (HeatRecovery Ventilator) units, the Humidity Control helpscontrol indoor maximum humidity level during fall, winterand spring. This control should not be installed in ahouse already equipped with other main controls (exceptthe 3-position switch). You will find a relative humidity %scale instead of a temperature scale meant to reduce thewindow condensation problems.

3-position switch

Some model may come with a 3-position mounted switchon the electical box on the exterior lower right front side.It is basically an airflow control that gives the customerthe choice between the low and high speed or the OFF(REMOTE) position. This OFF (REMOTE) position doesnot deactivate the optional controls.

WARNINGThe pollutant detecting control is not a warning device and must not be used in placeof a smoke detector or carbon monoxide detector.

7.5 SPECIAL COLD WEATHER TBI MODE FOR ERVS

The enthalpic core installed in ERVs requires extra protection when the outside temperature dropsbelow -15°C (5°F). A special operating mode called TBI (Time-Based Intermittent) is activated under these conditions.

Characteristics of cold weather TBI mode• activated when the outside temperature drops below -15°C (5°F).• 20/40 cycle (20 minutes LOW speed followed by 40 minutes OFF).• usual control of air supply via the main wall control is suspended (except for the OFF position).• optional control (20-minute push button) retain its temporary high speed activation capability.• deactivated when the outside temperature warms up higher than -15°C (5°F).

7.3 OTHER FEATURES

FURNACE INTERLOCK (for forced air heating system)

The furnace fan can be interlocked so that it will run simultaneously with the ERV or HRV to ensureproper distribution of fresh air throughout the house (see table section 7.4, to see if it’s available onyour unit).

PERMANENT MEMORY

Our electronic controls have a default memory feature in the event of a power outage. Even the dateof the last service reminder is maintained as a convenience to the homeowner.

CONTROL UPGRADES

All controls can be used on any ERV, so a Basic (or VT1W) control can be upgraded to the Electro (or VT2W)or the Detector (or VT3W) in the future (see table, section 7.4, for control availability on HRVs).

LIGHTED PUSH-BUTTON REMOTE 20-MINUTE SWITCH:This remote illuminated switch is typically installed in bathrooms, kitchen and laundry room to provide 20 minutes of high speed ventilation at the push of a button. The switch is supplied andmounted on a white single gang wall plate.

MECHANICAL TIMER

This timer allows up to 60 minutes of high speed operation to be selected from a remote location.

Alternate furnace interlock wiring

For a furnace connected to cooling system:On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” atthe thermostat and thereby turning on the cooling system. If you identify this type of thermostat, you must use the“alternate furnace interlock wiring”. An additional control relay will then have to be installed.

WARNINGNever connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Onlyuse the low voltage class 2 circuit of the furnace blower control.

WHAT YOU NEED TO BALANCE THE UNIT• A magnehelic gauge capable of measuring 0 to

0.25 inch of water (0 to 62.5 Pa) and 2 plastic tubes.

• Two ”Flow Measuring Stations” or two flow collars(the size will vary depending on the duct diameter).

PRELIMINARY STAGES TO BALANCE THE UNIT• Seal all the unit ductwork with tape. Close all windows and doors. • Turn off all exhaust devices such as range hood, dryer and bathroom fans.• Make sure all filters are clean (if it is not the first time you balance the unit).• Make sure the balancing dampers are fully open (F and G in figure 21).

Choose appropriate locations for the 2 flow collars (or flow measuring stations), according to figure 21:• On the exhaust air duct (first measuring location, A)• On the fresh air distribution duct (second measuring location, B• At least 36” away from the unit; at least 12” before or after a 90° elbow; at least 12” away from a register.

INSTALLATION OF FLOW COLLARS OR “FLOW MEASURING STATIONS”• If you are using Flow Collars:

Insert the flow collars in the duct at each location. Make sure their arrows are pointing in the direction of the airflow. Tape collars in place temporarily.

• If you are using “Flow Measuring Stations”:Cut a 1” (25.4mm) diameter hole in the duct at each location. Insert the “Flow Measuring Stations”. Make suretheir arrows are pointing in the direction of the airflow. Tape the “Flow Measuring Stations” in place temporarily.

BALANCING PROCEDURE1. Set the unit to high speed.

Make sure that the furnace blower is ON if the installation is in any way connected to the ductwork of the coldair return. If not, leave furnace blower OFF. If the outside temperature is below 0°C / 32°F, make sure the unit isnot running in defrost while balancing. (By waiting 10 minutes after plugging the unit in, you are assured thatthe unit is not in a defrost cycle.)

2. Place the magnehelic gauge on a level surface and adjust it to zero.

3. Connect tubing from gauge to flow collar (or “Flow Measuring Station”) in exhaustair stream at location A. Be sure to connect the tubes to their appropriate high/lowfittings. If the gauge drops below zero, reverse the tubing connections. NOTE: It is suggested to start with the exhaust air flow reading because the exhausthas typically more restriction than the fresh air, especially in cases of fully ducted installations and exhaust ducted installation. Place the magnehelic gauge uprightand level. Record the readings

4. Move tubing to FRESH air flow on the other side of the unit (location B) and note readings.Adjust the fresh air balancing damper F until the reading at B is approximately thesame as the reading at A. If the reading at B is less than the reading at A, then go backand adjust the exhaust balancing damper G to equal the fresh air flow.

5. Secure both dampers in place withtape or with a fastening screw.

6. If you are using flow collars, remove them, reconnect the duct and seal with duct tape. If you are using “FlowMeasuring Stations”, remove them and seal the holes with duct tape. Write the required air flow information ona label and stick it near the unit for future reference (date, maximum speed air flows, your name, phone numberand business address).

NOTES: Most flow collar kits provide a conversion chart located on the collar which enables you to convert magnehelicgauge readings to equivalent cfm values.The unit is considered balanced even if there is a difference of +/- 10 cfm (+/- 0.015 inch w.g.) between the twoair flow readings.If you are only using one flow collar or one “Flow Measuring Station”, then, after completing the first reading,transfer this measuring device to the other side of the unit and take the second reading.

*Method for testing the Detector wall control at start-up time (scenario 6).

1. Set the sensitivity knob at the maximum position.2. Plug in the unit and set the AIR SUPPLY CONTROL to MIN.3. Wat 5 minutes.4. Put pollution source (cigarette smoke, perfume or other strong vapors) near the control. Wait for 1 minute. The

unit should switch to high speed.5. Reset the unit (unplug, wait 10 seconds and plug back in) and reset the knob to medium sensitivity before leaving

the house. Warn the occupants that they should wait up to 48 hours before attempting any adjustments to theirwall control. (This waiting period will allow the control te restabilise after the test.)

NOTE: If the pollution level of the surrounding air is very high when you do the test, the test pollutants (see above)might not be strong enough to provoke high speed operation. If this case occurs, then allow the polluted airto clear by operating the unit at MAX. for several hours. Then reset the unit and retry performing the test.

11.1 MAIN CONTROLS (CONT’D)
