2. TYPICAL INSTALLATIONS

NOTE: Installation may vary according to the model number and the position (normal or reverse) in wich the unit is installed. There are three common installation methods.

2.1 FULLY DUCTED SYSTEM

(Primarily for homes with radiant hot water or electric baseboard heating. See illustration at right.)

Moist, stale air is exhausted from the high humidity areas in the home, such as bathrooms, kitchen and laundry room.

Fresh air is supplied to

VH0084

bedrooms and principal living areas. If required, bathroom fans and a range hood may be used to better

exhaust stale air. Homes with more than one level require at least one exhaust

See 3.5.1 for details

2.2 EXHAUST DUCTED SYSTEM (SOURCE POINT VENTILATION)

(For homes with forced air heating. See illustration at right.)

Moist, stale air is exhausted from the high humidity areas in the home, such as bathrooms, kitchen and laundry room. Fresh air is supplied to the cold air return or the supply duct of the furnace. If required, bathroom fans and a range hood may be used to better exhaust stale air.

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

NOTE: For this type of installation, it is not essential that the furnace

blower runs when the unit is in operation, but we recommend it.

2.3 SIMPLIFIED (VOLUME VENTILATION)

(For homes with forced air heating. See illustration at right.)

Fresh air and exhaust air flow through the furnace ducts, which simplifies the installation. The use of bathroom fans and a range hood is suggested to exhaust stale air. NOTE: For this type of installation, the furnace blower must be running when the unit is in

operation.

3.2 LOCATING AND MOUNTING THE UNIT

NOTE: Please note that these units can be installed in either the normal or reverse (upside down) position. See below for special instructions about reverse position.

Choose an appropriate location for the unit:

• Within an area of the house where the ambient temperature is kept between 10°C (50°F) and 40°C (104°F)

• Away from living areas (dining room, living room, bedroom), if possible

• So as to provide easy access to the interior cabinet for every three months maintenance, and to the control

panel on the 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

• Away from hot chimneys, electrical panel and other fire hazards

• Allow for a power source (standard outlet)

Hang the unit with the 4 chains and springs provided (see illustration at right).

CAUTION

If the unit is installed upside down, the thermal wheel must have its motor on top. Follow procedure below.

3.3 PLANNING OF THE DUCTWORK

a) Follow the instructions in Section 3.4 below to determine the appropriate duct diameters for your system. b) Keep it simple. Plan for a minimum number of bends and joints. Keep the length of insulated duct to a minimum. c) Do not use wall cavities as ducts. Do not use branch lines smaller than 4” Ø (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 for the kitchen exhaust duct.

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

3.4 CALCULATING THE DUCT SIZE

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

NOTE: Examples 3.4.1 and 3.4.2 use imperial measures. The same calculation applies to metric measures.

RECOMMENDED AIR FLOW MAXIMUM AIR FLOW

3.4.1 EXAMPLE OF CALCULATION

PROBLEM: My installation requires two exhaust registers (one for the kitchen, one for the bathroom). I will connect these registers to a main duct which will connect to the unit (high speed performance value of 140 cfm). What size of duct should I use for the main exhaust duct and for both end branches leading to the registers? (See illustration at right.)

SOLUTION: Simplified method. (For a more detailed method of calculating duct size refer to the ASHRAE or HRAI HANDBOOK). Main duct: Table above indicates a 6” Ø duct: Recommended air flow: 120 cfm; maximum air flow: 180 cfm. The high speed air flow of 140 cfm is close enough to the recommended value (120) and far away enough from the maximum value (180). Therefore a 6” Ø duct or larger 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 far away enough from the maximum value (110). Therefore a 5” Ø duct or larger is an appropriate choice for both end branches.

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

3.5 INSTALLING THE DUCTWORK AND THE REGISTERS

WARNING

Never install a stale air exhaust register in a room where there is a combustion device, such as a gas furnace, a gas water heater or a fireplace.

CAUTION

The ductwork is intended to be installed in compliance with all local and national codes that are applicable.

3.5.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1)

STALE AIR EXHAUST DUCTWORK:

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

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

• Install the kitchen register at least 4 feet (1.2 m) from the range.

• 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 with a 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, and mix with room air before descending to occupant level.)

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

3.5.2 EXHAUST DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.2)

TALE AIR EXHAUST DUCTWORK:

Same as for Fully Ducted System, described on point 3.5.1 above)

FRESH AIR DISTRIBUTION:

WARNING

When performing duct connection to the furnace, installation must be done in accordance with all applicable codes and standards. Please refer to your local building code.

CAUTION

When performing duct connection to the furnace supply duct, this duct must be sized to support the additional airflow produced by the ERV. Also, use a metal duct. It is recommended that the ERV is running when the furnace is in operation in order to prevent backdrafting inside ERV.

There are two methods for connecting the unit to the furnace:

ETHOD 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 ERV (use metal duct,

see illustration at right).

• Make sure that the ERV duct forms an elbow inside the furnace ductwork.

• If desired, interlock (synchronize) the furnace blower operation with the ERV

operation (see Section 5).

METHOD 2: RETURN SIDE CONNECTION

• Cut an opening into the furnace return duct not less than 10 feet (3.1 m) from the

furnace (A+B).

• Connect this opening to the fresh air distribution port of the ERV (see illustration at

right).

NOTE: For Method 2, it is not essential that the furnace blower runs when the unit

is in operation, but we recommend it. If desired, synchronize the furnace blower operation with the ERV operation (see Section 5).

3.6 CONNECTING THE DUCTS TO THE UNIT

CAUTION

If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts.

INSULATED FLEXIBLE DUCTS

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

 Pull back the insulation to expose the flexible duct and place it over inner port ring.

 Install good quality aluminum duct tape on flexible duct to prevent potential water leakage from duct.

 Attach the flexible duct to the port using tie wrap.

 Pull the insulation over the joint and tuck it between the inner and outer rings of the double collar.

 Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Fasten in place the vapor

barrier using the port strap (included in unit parts bag). To do so, insert one collar pin through vapor barrier and first strap hole, then insert the other collar pin through vapor barrier and center strap hole and close the loop by inserting the first collar pin in the last strap hole.

CAUTION

Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within the ducts.

4. CONTROLS (CONT’D)

4.1 INTEGRATED CONTROL (CONT’D)

4.1.1 BOOT SEQUENCE

The unit boot sequence is similar to a personnal computer boot sequence. Each time the unit is plugged after being unplugged, or after a power failure, the unit will perform a 30-second booting sequence before starting to operate. During the booting sequence, the integrated control LED will light GREEN (unit set in normal defrost) or AMBER (unit set in extended defrost) for 5 seconds, and then will shut off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence. During this RED light phase, the unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the RED light turns off and the booting sequence is done.

NOTE: No command will be taken until the unit is fully booted.

4.1.2 SETTING EXTENDED DEFROST

The unit is factory set to normal defrost. In cold region, it may be necessary to setup extended defrost. During the first 5 seconds of booting sequence, while the integrated control LED is GREEN, press on push button until the LED turns AMBER (about 3 seconds).

5. ELECTRICAL CONNECTION TO THE FURNACE

WARNING

Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low voltage class 2 circuit of the furnace blower control.

FOR A FURNACE CONNECTED TO A COOLING SYSTE M:

On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” at the thermostat and thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERNATE FURNACE INTERLOCK WIRING.

7. BALANCING THE UNIT

7.1 WHAT YO U NEED TO BALANCE THE UNIT

• A magnehelic gauge capable of measuring 0" to 0.5" of water (0 to 125 Pa) and 2 plastic tubes.

• The balancing chart of the unit.

7.2 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 the integrated balancing dampers are fully open.

• Make sure all filters are clean (if it is not the first time the unit is balanced).

VP0009

VD0280

7.3 BALANCING PROCEDURE

1. Set the unit to high speed.

Make sure that the furnace/air handler blower is ON if the installation is in any way connected to the cold air return ductwork. If not,

leave furnace/air handler blower OFF. If the outside temperature is below 0°C/32°F, make sure the unit is not running in defrost while balancing. (By waiting 10 minutes after plugging the unit in, you are assured that the 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 EXHAUST air flow pressure taps (see diagram

at right). Be sure to connect the tubes to their appropriate high/low fittings. If the gauge drops below zero, reverse the tubing connections.

NOTE: It is suggested to start with the exhaust air flow reading because the

exhaust has typically more restriction than the fresh air, especially in cases of fully ducted installations or source point ventilation.

Place the magnehelic gauge upright and level. Record equivalent AIR FLOW of

the reading according to the balancing chart.

4. Move tubing to FRESH air flow pressure taps (see diagram). Adjust the fresh

air balancing damper until the FRESH air flow is approximately the same as the EXHAUST air flow. If FRESH air flow is less than EXHAUST air flow, then go back and adjust the exhaust balancing damper to equal the FRESH air flow.

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

6. Write the required air flow information on a label and stick it near the unit for

future reference (date, maximum speed air flows, your name, phone number and business address).

VP0023

7. Install 4 pressure taps plugs (included in parts bag).

NOTES: 1. Use conversion chart provided with the unit to convert magnehelic gauge readings to equivalent cfm values.

2. The unit is considered balanced even if there is a difference of ±10 cfm (or ± 5 l/s or 17 m³/h) between both air flows.
