have unique ventilation requirements which should be 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 running 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 connected 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 as part number. 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 section. Kitchen Grille REMOVABLE FILTER The Round Diffuser is available in 4" (100mm) 6" (150mm) 8" (200mm) Round Diffusers Drain Connection (HRV Only) During a defrost cycle, the HRV may produce some condensation. 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 or freeze protection must be provided. The HRV cabinet has prepunched holes for the drain (see below). Insert the drain spout through the hole in the drain pan. Do not forget the “O ring” which seals each spout to the pan. REMEMBER TO HAND TIGHTEN ONLY the washer and lock nut which hold the drain spout in place. Construct a P-Trap using the plastic tee connector. Cut two lengths of hose and connect each piece to an end of the “T” fitting, then connect the other ends to the two drain spouts. Position the "T" fitting to point upward, andconnect the drain line. Tape or fasten base to avoid any kinks. This creates a “trap” which will hold some condensate and prevent odors from being drawn up the hose and into the fresh air supply of the HRV.

Weather hood arrangement is for drawing purposes only. 6' (2m) minimum separation required. 18" (460mm) above grade minimum or above anticipated snow level . 3. Due to the differences in pressure between the HRV and the equipment it is being connected to, the HRV air flow must be confirmed on site, using the balancing procedure found in the installation manual.
