Installation

Stale Air Exhaust System

The stale air exhaust system draws air from the points in the house where the worst air quality problems occur. Stale air ducts should be installed in the bathroom, kitchen, and laundry room. Applications such as green- houses, atriums, swimming pools, saunas, etc. have u n i q u e v e n t i l a t i o n r e q u i r e m e n t s w h i c h s h o u l d b e addressed with an isolated ventilation system. Also, the air handler return duct may be used to exhaust from. In this method, the exhaust air is not ducted back to the HRV with "dedicated lines" from bathrooms, kitchens, etc. Instead, the exhaust air is drawn out of the cold air return of the air handler. The air handler blower must be run-

ning when the unit is operating for this system to be effective.

CAUTION

Balancing Dampers and Grilles

Balancing dampers and/or adjustable grilles should be used to balance the flow rates into and out of various rooms.

Grilles or diffusers should be positioned high on the wall or in the ceiling. Kitchen exhaust grilles must never be con- nected to a range hood. They should be installed at least 4 feet (1.2m) horizontally away from the stove. A hinged 6”X10” (150 X 250mm) rectangular kitchen exhaust grille is available. This grille includes a removable grease filter. Canadian building codes require that kitchen grilles be equipped with washable filters.

Field-supplied balancing dampers should be installed external to the unit to balance the amount of stale air being exhausted with the amount of fresh air being brought into the house. Refer to Air flow Balancing sec- tion.

Drain Connection (HRV Only)

During a defrost cycle, the HRV may produce some con- densation. This water should flow into a nearby drain, or be taken away by a condensate pump.

CAUTION

The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point.

The HRV has a condensate pan and drain spout built into the door. Construct a P-Trap by creating a loop in the drain. This creates a “trap” which will hold some conden- sate and prevent odours from being drawn up the hose and into the fresh air supply of the HRV.

"P" Trap (HRV only)

CAUTION

Drain trap and tubing MUST be below bottom of door with 1/4" per foot downwards slope away from unit.

Note: Secondary drain pan may be required to protect from condensate leakage.
