Humidity level selector:

The wall control includes a dehumidistat to set the

humidity level you desire. When humidity level in

your house is greater than what you have selected,

the unit lowers it by exchanging with fresh air from

outside.

Continuous low speed exchange mode:

Select the low speed position with the main

switch located on the right side of the unit. The

unit will continually exchange with the exterior

at low speed and at high speed when there is an

excess of humidity.

Intermittent exchange mode (REMOTE)

Select the remote position with the main switch

located on the right side of the unit. The unit will

operate if the humidity level is higher, than

selected.

Continuous high speed exchange mode:

Select the high speed position with the main

switch on the unit. The unit will operate at high

speed whatever the selection made on the wall

control.

1.1 DESCRIPTION OF THE WALL CONTROL FUNCTIONS

1 AIR EXCHANGER WITH HEAT RECOVERY WALL CONTROL

The control shows the relative humidity levels. You can then select the desired level of relative humid-

ity. During the cold seasons, we recommend to select accordingly to the outside temperature. This

way, you will reduce risks of condensation on your windows while having a better efficiency of your

Air Exchanger with Heat Recovery.

NOTE: Remember, during the cold seasons, the colder the outside temperature is, the more

risks you have to get condensation on your windows. If you reduce the level of relative

humidity inside your house, the risks of condensation on your windows will decrease.

To evaluate the humidity level in your home, follow these steps:

1. Set the control at 80% humidity.

2. Turn the humidity selector clockwise towards the minimum position (20%).

3. Stop when a “click“ is heard.

4. This “click“ indicates the current humidity level in your home.

WARNING

The way your house has been built may have an impact on the results whatever control

method is adopted. Therefore, it is better to evaluate the behavior of your house. If, during

winter, you notice that there is a recurring problem with condensation even if the control

is positioned properly, it would be appropriate to lower the humidity level in your home

further. However, it is important to realize that the comfort level for human beings is

between 30% and 45% humidity. What level to choose? The choice is yours and with little

experience, you will find the best point suited for you.

1.2 THE RELATIVE HUMIDITY LEVEL, FOR THE DILIGENT

Attention: To guarantee your safety, you should always disconnect the unit from the

power source before doing any maintenance.

• Open the door. If necessary, it can be removed by lifting it upwards.

• You now have access to all the components for maintenance.

2 MAINTENANCE

2.1 HOW TO ACCESS THE COMPONENTS

1) Stale air port: is connected to the registers located in the larger rooms of the house.

2) Fresh air port: brings fresh air from the outside into the unit.

3) Exhaust port: exhausts stale air to the outside, after the air has transferred its heat inside the

heat recovery core.

4) Distribution port: distributes fresh air into the house, after it has absorbed the heat of the stale

air in the heat recovery core.

5) Mechanical filters (2): trap the dust contained in the air and prevent the heat recovery core

from becoming obstructed.

6) Heat recovery core: it transfers the heat between the two air streams.

7) Blowers: draw fresh air from the outside and exhaust stale air to the outside.

8) Condensation tray: is used to capture the water produced during heat transfer and defrost.

9) Drainage tube: is connected to the condensation tray and serves to drain the water within.

10) Electronic control circuit: ensures proper operation of the unit.

11) Automatic defrost unit: consists of one damper actuator, dampers and the related controls.

The defrost cycle is electronically controlled in response to the outside temperature (-5°C to

-40°C) and will increase in frequency as the temperature decreases. Its duration is of 5 or

6 minutes.

12) Electrical cord: (120 V, 1,2 A).

13) Main switch: located on right side of the unit (not shown).

2.2 DESCRIPTION OF UNIT

IMPORTANT NOTE: Hot water and a strong detergent will damage the heat recovery core.

The air filters are washable. Under normal conditions, we recommend that they be washed every

3 months.

- Use a vacuum cleaner to remove the heaviest portion of accumulated dust.

- Then wash in hot water.

Regularly check the screen on the exterior intake hood and clean when necessary.

Also check during very cold weather because ice may accumulate on the screen

located at the exterior intake hood.

B) PROLONGED

Annual service should include:

1) Cleaning filters, heat recovery core and the exterior air intake hood.

2) Cleaning the wheels and the blower blades.

3) Cleaning the condensation tray with soapy water (make sure that the drain is not clogged).

A) REGULAR

WARNING: During maintenance, always disconnect the unit from its power source.

Motor: The motor is factory lubricated for life. Lubricating the bushings is not recommended.

The heat recovery core must be handled with care. We recommend that it be washed once a year,

following the season of most intense use, in order to ensure maximum efficiency of the plastic

partitions. Allow the heat recovery core to soak for 3 hours in a solution of warm water and mild

soap. Rinse under a heavy stream of water.

WARNING :

1- Make sure at all times, the outside hoods are free from any snow during the winter

season. Moreover, during a big snow storm, it is important to check your unit so it

doesn’t draw in any snow. If this is the case, do not operate the unit for a few hours.

2- Do not use the Air Exchanger with Heat Recovery during sanding of gyproc joints,

during construction or renovation of the house. This dust will damage the unit.

3- Do not use the Air Exchanger with Heat Recovery during any varnishing work.

The vapors from the varnish can damage the unit.

4- Since the electronic control system of the unit is incorporated with a

microprocessor, it may not operate correctly because of external noise or very short

power failures. If this happens, disconnect the power plug from the wall outlet, and

wait approximately 10 seconds; then plug the unit in again to resume operation.

A) SUGGESTED TOOLS:

The use of the following tools is suggested for installing your Air Exchanger with Heat Recovery:

4.2 PREPARATION FOR THE INSTALLATION OF YOUR AIR EXCHANGER WITH

HEAT RECOVERY

A square-headed (Robertson No. 2) or star-shaped (Philips No. 1) screwdriver.

A square-headed (Robertson No. 2) or star-shaped (Philips No. 2) screwdriver.

A flat-headed screwdriver 40 mm (5/32’’).

A pair of cutter pliers.

An electric drill.

A jig saw or a hand or electric compass saw.

A caulking gun and a tube of silicone sealer.

A roll of adhesive duct tape.

A pair of metal shears (if the exterior covering of your house is aluminum or vinyl).

A chisel and hammer (if the exterior covering of your house is brick).

B) DETERMINING THE LOCATION OF COMPONENTS

Several suggestions to allow you to determine the ideal location for each of the components.

Stale air intake register:

- Always locate the register at the highest point in the house, as humidity is concentrated at this point.

- Position the register as far away as possible from the stairway in such a way that the air circulates in

all the lived-in spaces in the house.

- Avoid installing the register in a bathroom or a bedroom; place it in a location where the air circulates

freely (eg.: living room, kitchen, hallway).

- Position the register on a wall backing into a closet. This will allow you to install the flexible duct in the

closet.

- For silent operation, leave a minimum of 15 feet of flexible duct between the stale air intake register

and the unit.

- Do not install the register close to a source of heat. The temperature of the intake air must not exceed 50°C.

Fresh air distribution register:

- Always locate the register in a large, open area in the basement to ensure the greatest possible

circulation of air.

- Position the register as far away as possible from the stairway in such a way that the air circulates in

all the lived-in spaces of the house.

- Do not ventilate basements with earth floors or the underfloor spaces. These are not considered to be

lived-in spaces.

- If you have a wood stove, place the register in such a way that the heat from this unit can be distributed

throughout the house.

- For silent operation, leave at least 15 feet of flexible duct between the fresh air distribution register and

the unit.

Unit:

- Position the unit where there is no possibility of freezing (10°C or more). Generally, we recommend the

basement or a closet.

- Place the unit as close as possible to an outside wall to minimize the length of the insulated ducts.

- If possible, place the unit close to a drain and an electrical outlet.

- Position the unit in such a way as to respect the lengths of the ducts supplied in the other parts kit.

To facilitate the installation of your unit, follow these steps.

Note: For a better view of the overall installation, refer to the assembly drawings on

pages 15 and 16.

- Place the unit far from the lived-in areas of the house where peace and quietness are desired.

- The location must be easily accessible for maintenance of the unit.

Exterior openings:

- Position the fresh air intake port far from sources of contamination such as the garage, dryer

outlet, central vacuum system, gas regulator.

- Place the openings at least 450 mm (18 inches) above the ground.

- Leave, at least, 2 meters (6 feet) between the two openings.

- Make the two holes in the end-joists around the house.

Wall control:

- Locate the wall control on the ground floor of the house.

- Locate the wall control in an area where air circulates (eg.: hallway, living room, dining room, etc.).

- The wall control should be positioned approximately 1.5 meter (60 inches) from the floor.
