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 Bal

When the outside air temperature drops below 27°F (-3°C), defrost is activated which provides for an automatic defrost cycle. During the automatic defrost cycle the fresh air supply is shut off while the exhaust fan continues to operate. This allows warm inside air to flow through the heat exchanger core melting frost accumulation. After the defrost period, the fresh air supply fan automatically returns to the normal speed and fresh outside air continues to be drawn into the building. Water from

10 Electrical The HRV unit should be plugged into a standard designated (120VAC) electrical outlet with a ground. The outlet should be serviced by a separate 15 amp/120V circuit. An extension cord should not be used with this appliance. A qualified service technician should make any required electrical connections. Remote Control Connections Prior to connecting remote devices, it is advisable to run self test on the HRV/ERV. Low voltage connections between the remote controls, the dehumidistat,
