The straps are designed to reduce the possibility of noise, resonance or harmonics; therefore using the full length of the strap between the HRV/ERV and the floor joists is recommended. Electrical The HRV/ERV should be plugged into a standard designated (120VAC) electrical outlet with ground. It is not recommended that an extension cord be used for this appliance. If further wiring is required, then a licensed electrician should make all electrical connections. It is recommended that a separate 15 amp/120 volt circuit be used. WARNING: In order to prevent electric shock when cleaning or servicing the HRV/ERV, it is extremely important to confirm the polarity of the power line that is switched by the safety (disconnect) switch. The hot line (black) is the proper line to be switched. To confirm the proper polarity, use a voltmeter or test lamp to ensure there is no power after the switch when the door is open. Check between that point and ground (on the cabinet). This must be done as dwellings are occasionally wired improperly. Always make sure that the HRV/ERV is properly grounded. Connecting Appliances to the HRV/ERV It is not recommended that any of the following appliances be connected to the HRV/ERV: • clothes dryer • range top • stovetop fan • central vacuum system Lint, dust or grease will collect in the HRV/ERV, damaging the unit. NOTE: Connecting any of these to the HRV/ERV will invalidate your warranty. Installing the Drain Line and P-Trap (not on all models) When defrosting, the HRV/ERV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. The HRV/ERV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point. At the bottom of the cabinet there are prepunched hole for the drain pan connectors (see below). Insert the drain spout through the hole in the drain pan. Do not forget the “O Ring” which seals the connector to the pan. REMEMBER TO HAND TIGHTEN ONLY the washer and lock nut which hold the drain connector 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. Allow the "T" fitting to point upwards, and connect the drain line. Tape or fasten base to avoid any kinks. This creates a “trap” which will hold some condensate and prevent odours from being drawn up the hose and into the fresh air supply of the HRV/ERV.

Always try to keep duct runs as short and straight as possible.See Installation Diagrams for various installation options. Outside Weatherhoods The fixed covered hoods have a built-in bird screen with a 1/4" (6 mm) mesh to prevent foreign objects from entering the ductwork. Locating the Intake Weatherhood • Should be located upstream (if there are prevailing winds) from the exhaust outlet • At least 6' (2 m) from the exhaust weatherhood • At least 6' (2 m) away from dryer vents and furnace exhaust (medium or high efficiency furnaces) • A minimum of at least 6' (2 m) from driveways, oil fill pipes, gas meters, or garbage containers • At least 18" (457 mm) above the ground, or above the depth of expected snow accumulation • At least 3' (1 m) from the corner of the building • Do not locate in a garage, attic or crawl space Locating the Exhaust Weatherhood • At least 6' (2 m) from the ventilation air intake • At least 18" (457 mm) above ground or above the depth of expected snow accumulation • At least 3' (1 m) away from the corner of the building • Not near a 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 weatherhood, its outside perimeter must be sealed with exterior caulking. Installing the ducting from the weatherhoods to the HRV/ERV The inner and outer liners of the flexible insulated duct must be clamped to the sleeve of the weatherhoods (as close to the outside as possible) and the appropriate port on the HRV/ERV. It is very important that the fresh air intake line be given special attention to make sure it is well sealed. A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the HRV/ERV port and the weatherhood prior to clamping. To minimize air flow restriction, the flexible insulated duct that connects the two outside weatherhoods to the HRV/ERV should be stretched tightly and be as short as possible. Twisting or folding the duct will severely restrict air flow.
