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.
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, or the fan timer should be made by a quali-
fied service technician. Low voltage wires from the remote
controls are connected to the HRV micro-processor board.
In order to prevent electric shock when cleaning
or servicing the HRV, 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).
Always make sure that the HRV is properly
grounded.
