Electrical
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
WARNING
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.
