•  DO NOT use the condensing unit as a bench or table. 
•  Do not place the condensing unit where the sound and vibration caused by running the unit will a cause a 

nuisance. Vibration dampening material may be installed between the condensing unit base and the mounting 

pad if required.

•  Allow sufficient clearance to handle the unit’s overall dimensions.
•  Place the condensing unit where there is adequate space for the unit and the air required by the unit.
•  Install the condensing unit with space to access the top and side panels for maintenance and service.
5.2 B Electrical Requirements

The condensing unit requires a dedicated 120Vac 20 Amp circuit capacity. Install a properly sized branch circuit 

disconnect (20 Amp) within sight of the unit. The Installer must supply the power wiring for the condensing unit. 

The power wiring must have a Minimum Circuit Ampacity of 20A and be run within a rain-tight conduit. The con-

densing unit must be grounded as required by applicable code(s).

Field Wiring the Condensing Unit:

1.  Take off the panel (top), by removing the one screw that secures it to the condensing unit. 

2.  Loosen the two strain relief block screws.

3.  Insert the power and control wires through the strain relief block.

4.  Connect the power supply wires and control wires to the corresponding terminals on the terminal board.

5.  Ground the condensing unit in accordance with local and national electrical codes.

6.  Secure the power and control wires to the strain relief block by tightening the screws.

7.  Reinstall the panel (top) by inserting the one screw that secures it to the condensing unit.

 

Condensing Unit Electrical Control Connections:

Connect the black control wire (8) from the dehumidifier to terminal N on the condensing unit terminal block.
Connect the black control wire (9) from the dehumidifier to terminal 1 on the condensing unit terminal block.
