6. Typical Installations

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

Moist, stale air is exhausted from the high humidity areas inthe home, such as bathrooms, kitchen and laundry room.Fresh air is supplied to bedrooms and principal living areas.

If required, bathroom fans and a range hood may be used tobetter exhaust stale air.

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

6.1 FULLY DUCTED SYSTEM

There are three (3) common installation methods.

VH0002

*Installations may vary according to the model number and the position (normal or reverse) inwhich the unit is installed.

figure 1

See 7.4.1 for details

6.2 EXHAUST DUCTED SYSTEM (SOURCE POINT VENTILATION)

(For homes with forced air heating. See figure 2.)

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

Homes with more than one level require at least oneexhaust 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.

VH0006


figure 2

6.3 SIMPLIFIED (VOLUME VENTILATION)

(For homes with forced air heating. See figure 3.)

Fresh air and exhaust air flow through the furnace ductswhich simplifies the installation.

The use of bathroom fans and a range hood is suggested toexhaust stale air.

NOTE: For this type of installation, the furnace blower should be running when the unit is in operation.

VH0007figure 3


7.2 PLANNING OF THE DUCTWORK

11

7. Installation

INSPECT THE CONTENTS OF THE BOX

• Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, door latches,door hinges, dampers, duct collars, cabinet, etc.

• Inspect the interior of the unit for damage. Ensure that the fan motor assembly, recovery module, insulation,dampers, damper actuator and condensation tray (Solo) are all intact.

• If the unit was damaged during shipping, contact your local distributor. (Claim must be made within 24 hours afterdelivery.)

• Use checklist included with the unit to ensure that no parts are missing.

7.1 LOCATING AND MOUNTING THE UNIT

NOTE: Please note that the unit can be installed in either the “normal” or “reverse” (upside down) position.Choose an appropriate location for the unit:• Within an area of the house where the temperature is kept above 10°C / 50°F

and below 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 and

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

(Solo models only.)• 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 figures 4 and 5).

VD0038

VD0039A

1/8”(3 mm)

figure 4

figure 5

figure 6

CAUTIONMake sure the unit is level, with a 1/8’’ (3 mm) tilt backwards (seefigure 6).

a) Follow the instructions in Section 6.3 next page 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 rangehood. 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.

WARNINGWhen performing installation, servicing or cleaning the unit, it is recommended to wear safetyglasses and gloves.

!

WARNING!When applicable local regulation comprises more restrictive installation and/or certificationrequirements, the aforementioned requirements prevail on those of this document and theinstaller agrees to conform to these at his own expenses.

12

7. Installation (cont’d)

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 andnever install a duct if its air flow exceeds the maximum value.

NOTE: Examples 7.3.1 and 7.3.2 use imperial measures. The same calculation applies to metric measures.

7.3.1 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 the two end branches leading to the registers? (See figure 7.)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 enough away from the maximum value (180). Therefore a 6” Ø duct or larger is an appropriate choice for the main exhaustduct.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 enough away from the maximum value (110). Therefore a 5” Ø duct or larger is an appropriate choice for the 2 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.

7.4 INSTALLING THE DUCTWORK AND REGISTERS

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

!

7.4.1 Fully Ducted System (as illustrated in Section 6.1)

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 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 tooccupant level.)

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

7.4.2 Exhaust Ducted System (Source Point Ventilation) (as illustrated in Section 6.2)

Stale air exhaust ductwork: (same as for Fully Ducted System, described on point 7.4.1)

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 metal duct, see figure 9).• Make sure that the HRV/ERV duct forms an elbow inside the

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

tion with the HRV/ERV operation. (See Section 9.3).

Method 2: Return side connection• Cut an opening into the furnace return duct not less than

10 feet (3.1m) from the furnace (A+B).• Connect this opening to the fresh air distribution port of the

HRV/ERV (see figure 10).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 HRV/ERV operation.(See Section 9.3).

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

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

7.4.3 Simplified installation (Volume Ventilation) (as illustrated in Section 6.3)

There are two methods (figures 11 and 12) for connecting the unit to the furnace:

Method 1: return-supply Method 2: return-return

Stale air intake:• Cut an opening into the furnace return duct (not less than 10 feet (3.1 m) from the furnace).• Connect this opening to the stale air intake port on the HRV/ERV as shown.

Fresh air distribution: (same instructions as for Method 1 or Method 2, Section 7.4.2).

For Method 2 (return-return) make sure there is a distance of at least 3 feet (0.9 m) between the 2 connections to the furnace.NOTE: For Method 1, it is not essential to synchronize the furnace blower operation with the unit operation,

but we recommend it.

Insulated flexible ductUse the following procedure for connecting the insulated flexible duct to the ports on the unit (exhaust to outside andfresh 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 water dripping due to condensation on theexterior surface of the duct.

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

Rigid ductUse 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 ducts to these ports(fresh air distribution port and stale air exhaust port as shown on figure 13).

7.5 CONNECTING THE DUCTS TO THE UNIT

CAUTIONMake sure that the vapor barrier on the insulated ducts does not tear during installation to avoidcondensation within the duct.

CAUTIONDo not use screws to connect rigid ducts to the ports.

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” at thethermostat 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).Only use the low voltage class 2 circuit of the furnace blower control.

!

9.5 FURNACE INTERLOCK TYPES

The new TII (Timed Intermittent Interlock) function consists in 2 modes: the standard mode and the special mode.Therefore, the electronic board terminal of the Solo and Duo units has now 2 additional jumpers intalled across C andD terminals.

STANDARD MODE

The standard mode is the default mode (the interlock function stay as it was). On standard mode, the jumper positionson terminal C and D keep them non-active:

SOLO UNITS DUO UNITS

SPECIAL MODE

The special mode drives the furnace interlock relay independently than the HRV/ERV operation. The K4 relay is activated for 10 minutes, and then is deactivated for a 20-minute period, no matter the HRV/ERV command, even ifthe HRV/ERV is stopped. To perform the special mode, unplug the unit and change the jumper locations as shownbelow:

SOLO UNITS DUO UNITS

NOTE: For both Solo and Duo units, C and D terminals are now activated.

WHAT YOU NEED TO BALANCE THE UNIT• A magnehelic gauge capable of measuring 0 to 0.5 inch of water

(0 to 125 Pa) and 2 plastic tubes.• The balancing chart provided with the unit.

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 balancing dampers are fully open. • Make sure all filters are clean (if it is not the first time you balance the

unit).

BALANCING PROCEDURE1. Set the unit to high speed:

Make sure that the furnace blower is ON if the installation is in any wayconnected to the ductwork of the cold air return. If not, leave furnace blowerOFF. 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 that the unit is not in a defrost cycle.)Disconnect the wire of the bypass damper (Duo only).

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).Be sure to connect the tubes to their appropriate high/low fittings. If thegauge 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 thefresh air balancing damper until the fresh air flow is approximately thesame as the EXHAUST air flow. If fresh air flow is less than exhaust airflow, then go back and adjust the exhaust balancing damper to equal thefresh air flow.

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

6. Write the required air flow information on a label and stick it near the unitfor future reference (date, maximum speed air flows, your name, phonenumber and business address). Connect the wire of the bypassdamper (Duo only).

NOTE: The unit is considered balanced even if there is a difference of ± 10 cfm or ± 5 l/s or 17 m³/h between the two air flows.

• Review with the user the steps required for the regular maintenance of her/his ventilation system. These steps aredescribed in detail in the user manual:

• Warn the user of the necessity to rebalance the system following a major house renovation or following the installation of any extra registers.

• Make sure the user understands how to use the main control as described in the user manual.

13. Maintenance / Instructions for User

FOUR TIMES A YEAR:• Inspect the intake hood, and clean if needed.• Clean the filters.• Clean the interior of the cabinet and clean the door.• Clean the condensation tray and inspect the drain tubing (SOLO only).

ONCE A YEAR:• Clean the recovery module (core or thermal wheel).• Clean the blades of the blower wheels if needed.

WARNINGRisk of electric shocks. Before performing any maintenance or servicing, always disconnect theunit from its power source.

!

CAUTIONDo not oil the motor. It is already permanently lubricated.

14. Troubleshooting

27

Problems Possible causes You should try this

1. The error code E1 is displayed on Altitude orDeco-Touch wall controlscreen.

• The wires may be inreverse position.

• The wires may be broken.• The wires may have a

bad connection.

• Ensure that the color coded wires have been connected totheir appropriate places.

• Inspect every wire and replace any that are damaged.• Ensure the wires are correctly connected.

2. There is no outside temperature displayedon Altitude wall controlscreen .

• The unit thermistor is defective.

NOTE: At its very start-up or after a power failure, it takessome minutes before the outside temperatureappears on screen. The delay duration dependson which operation mode the wall control is set.The shortest delay is obtained when the wall control is set on MIN or MAX in VENT Mode.

• Replace the unit thermistor.

3. Altitude or Deco-Touchwall control screen alternates between normal display and E3.

• The Altitude or Deco-Touch wall controlis defective.

• Replace the Altitude or Deco-Touch wall control.

4. On Altitude wall control,there is an important difference between temperature displayedand real temperature.

• The unit thermistor isdefective.

• The unit damper hasbeen blocked or broken.

• Replace the unit thermistor.

• Check for the proper operation of the unit damper;replace if necessary.

5. The damper actuatordoes not work.

• The 9-pin connectormay have a loose connection.

• The damper actuatormay be defective.

• The circuit board maybe defective.

• Unplug the unit and check to make sure all the crimp connections are secured. Check the damper actuatorconnections as well.

• Feed 120 V directly to the damper actuator. If the problempersists, replace the damper actuator.

• Replace the circuit board if the problem is not solvedby the above.

NOTE: Be sure to unplug and inspect the unit before proceeding with these steps.

If the unit does not work properly, reset the unit by unplugging it for one minute and then replug it. If it stillnot working properly, refer to table below.

13. Troubleshooting (cont’d)

Problems Possible causes You should try this

6. Unit doesn't work. • The circuit board maybe defective.

• The power cord fusemay be blown.

• Unplug the unit. Disconnect the main controland the optional control(s) (if need be).Jump B and G (BLACK and GREEN) terminals. Plug the unit. If the motor runson high speed and the damper opens,the circuit board is not defective.

• Unplug the unit. Unscrew the fuse holder(grey circle on illustration beside).Check if the fuse is blown (the strand isbroken). If it is blown, replace the fuseaccording to the specifications on theunit power cord tag.

7. The wall control doesnot work.

• The wires may be inreverse position.

• The wires may be broken.• There may be a short-circuit.• The wire in the wall

OR the wall controlmay be defective.


• Ensure that the color coded wires have been connectedto their appropriate places.

• Inspect every wire and replace any that are damaged.• With the help of a multimeter, check for continuity.• Jump B and G (BLACK and GREEN) terminals. If unit

switches to high speed, remove the wall control and testit right beside the unit using another shorter wire. If thewall control works there, change the wire. If it doesn’t,change the wall control.

• If the unit does not switch to high speed, replace thecircuit board.

8. The Dehumidistat doesnot work OR the20/40/60-min. push-button timer doesnot work or is indicatorlight does not stay on.

• The dehumidistat ORpush-button may bedefective,

• Jump the OL and OC terminals. If unitswitches to high speed, remove theDehumidistat or push-button and test itright beside the unit using anothershorter wire. If it works there, changethe wire. If it doesn’t, change theDehumidistat or push-button.

9. The defrost cyclet doesnot work (the fresh airduct is frozen OR thefresh air distributed isvery cold).

• Ice deposit may be hindering the damperoperation.

• The damper rod or theport damper itself maybe broken.

• The damper actuatormay be defective.


• The thermistor may bedefective.

• Remove the ice.

• Inspect these parts and replace if necessary.

• Plug in the unit and select “MIN” or “MAX”. Press the doorswitch and see if the port damper opens. If it doesn’topen, feed 120V directly to the damper actuator. If theport damper still doesn’t open, replace the damper actuator.

• Unplug the unit. Unplug the defrost sensor wire (see J4on electrical diagram Section 9). Plug the unit back in. Select “MIN” and make sure the unit is adjusted for lowspeed operation (turn all Humidity Controls maximum counterclockwise).Wait 3 minutes. The unit should switch to high speed and the damper at the fresh air intake port should close (defrost mode). If this doesn’t happen,then replace the circuit board.

• If the defrost mode works well after having disconnectedthe thermistor wire (above test), this means the thermistoris probably defective. You should replace it.
