Due to the broad range of installation and operational conditions, consideration must be given for the possibility of condensation forming on the unit or connecting ducting. Objects below the installation may be exposed to condensate. • At least 3' (1 m) away from the corner of the building* • At least 3’ away from gas meter, electric meter or a walkway where fog or ice could create a hazard* • Not into a garage, workshop or other unheated space When installing the weather hood, its outside peri

Remove and wash filters and core and replace. Outside hoods should be visually checked for blockage regularly. 5. Drain is required as shown above. 6. Built in balancing damper may require seasonal adjustments. 8 Air Flow Balancing Air Flow Balancing It is necessary to have balanced air flow in an HRV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit. If the air flow is not properly balanced, then: • The HRV may not operate at its maximum efficienc

NEVER install an HRV/ERV in a situation where its normal operation, lack of operation or partial failure may result in the backdrafting or improper functioning of vented combustion equipment!!!

During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During the summer months, the cool outgoing stale air from the air conditioned dwelling is used to help cool the incoming fresh air. Your HRV features the digital electronic BASE MODULE that uses a microprocessor to control fan speed and unit operation. Both digital (3 wire) and standard (2 wire) remote devices can control the HRV when conne

The drain line must be located in an area that is not subject to freezing and should beoutletted into floor drain sink, standpipe or condensate pump. Make sure the drain line slopes down to provide proper condensate removal. Should no "fall" be available, a condensate pump may be used. NOTE: A P-Trap must be made to prevent odours from being drawn in through the drain line. THE DUCTWORK SYSTEM A well designed ducting system will allow the HRV to operate at its maximum efficiency.

Furnace blower is recommended to operate when HRV is on to provide good air distribution. 2. Weatherhood arrangement is for drawing purposes only. 6' (2 m) minimum separation required. 18" (460 mm) above grade minimum. 3. Due to the differences in pressure between the HRV and the equipment it is being connected to, the HRV's airflow must be confirmed on site, using the balancin

Optional Remote Controls will initiate high speed ventilation. Remote controls with an ON/OFF switch (refer to "Remote Control Devices" in this manual) will shut the entire system down when the remote control is in the OFF position. Changing the remote control from OFF to STANDBY can be achieved by Setting the DIP Switch a
