1.0 Functions of your HRV

Your Heat Recovery Ventilator eliminates the problems of excessive humidity by exhausting stale and humid air to the outside and by drawing in fresh air. The unit offers superior air quality and fresh air sensation, an important factor to overall comfort, by eliminating the accumulation of pollutants and humidity.

The unit also comes equipped with a heat recovery core which reduces ventilating costs in winter.

The Heat Recovery Ventilator is a Ventilation system which carries out three main operation:

1.1 Air Exchange

The unit exhausts stale and humid air from the house and replaces it with fresh air from the outside.

85 to 141 l/s (180 to 300 cfm)

1.2 Heat Recovery

During winter, the unit recovers the heat contained in the stale air before it is exhausted, and transfers it to the fresh air drawn from the outside

(reverse process in summer).

1.3 Circulation

(available with ULTIMA control only)

During the circulation mode, when the selected level of humidity is reached, the unit stops to exchange air with the exterior. Continuous circulation is thus undertaken inside the home and insures the purification of the ambiant air. A mechanical filter traps the large dust particles

(those visible to the eye).

3.0 Description of the Unit

1) Stale air intake 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) Foam filter: traps the dust contained in the air and prevents the heat recovery core from becoming obstructed.

6) Heat recovery core: is a counterflow type for 2000 HE, 3000 HE,

1.8 HE, 2.6 HE models and is a crossflow type for the other models.

It transfers the heat between the two air streams.

7) Blowers: draw fresh air from the outside and exhaust stale air to the outside. The blower wheels are driven by two motors for 2000 HE,

3000 HE, 1.8 HE, 2.6 HE models. The other models have just one motor.

8) Capacitor: is indispensable to proper motor operation.

9) Condensation tray: is used to capture the water produced during heat transfer and defrost. (in cold climate)

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

11) Electronic control circuit: located inside the electrical box, insures proper operation of the unit.

12) 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 (23°F) to

-40°C (-40°F)) and will increase in frequency as the temperature decreases. Its duration is of 5 or 6 minutes according to models.

13) Control Connector: located inside the electrical box, allows to connect the control and override switch as a timer, a dehumidistat or a switch.

14) Electrical cord: for 120V electrical supply.

5.0 Maintenance

!

WARNING

Risk of electric shock. Before performing any maintenance or servicing, always disconnect the unit from its power source.

5.1 Regular Maintenance

1 ) The motors are factory lubricated for life. Lubricating the bearings is not recommended.

CAUTION

Because the unit is suspended, two people are recommended to remove or install the heat recovery core.

Do not hold the heat recovery core using its plastic extrusions as handles.

2) 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 insure 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.

CAUTION

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

3) 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.

4) Regularly check the screen on the exterior intake hood and clean when necessary. Also check during very cold weather because ice may grow on the screen located at the exterior intake hood.

5.2 Annual Maintenance

NOTE: Ask your installer for an annual service contract.

Annual service should include:

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

4) Running the system and checking the different operating modes.

5) Measuring and calibrating rates of flow.
