19 The HRV unit should be plugged into a standard designat- ed (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.
20 Operation Self T est The ventilator will automatically initiate a self test sequence when power is applied. Fan motor is cycled and then damper motor is cycled.

22 When using the Interface relay contacts to initiate b lower operation on a fur- nace, cer tain thermostats will initiate the outdoor cooling condenser when R and G are closed. Use this wiring configur ation to prev ent the Interf ace rela y contacts from initializing the condenser unit.
23 The fan defrost HRV is equipped with an electronically controlled fan defrost system to remove frost that collects on the warm air side of the aluminum heat transfer sur- faces of the heat exchanger core. When the outside air temperature drops below 27°F (3°C), defrost is activated which provides for an automatic defrost cycle.
24 It is necessary to have b alanced air flow in an H R V . The volume of air b rought in from the outside must e q ual the volume of air e x hausted b y the unit.
