CONNECTIONS

GENERAL INFORMATION & GROUNDING

Check the electrical supply to be sure that it meets the values specified on the unit nameplate and wiring label.

Power wiring, control (low voltage) wiring, disconnect switches and over current protection must be supplied by the installer. Wire size should be sized per NEC requirements.

All field wiring must USE COPPER CONDUCTORS ONLY and be in accordance with Local, National, Fire, Safety & Electrical Codes. This unit must be grounded with a separate ground wire in accor- dance with the above codes.

The complete connection diagram and schematic wiring label is located on the inside surface of the unit service access panel.

FIELD CONNECTIONS POWER WIRING

1.Install the proper size weatherproof disconnect switch outdoors and within sight of the unit.

2.Remove the screws at the top and sides of the corner cover. Slide corner cover down and remove from unit.

3.Run power wiring from the disconnect switch to the unit.

4.Route wires from disconnect through power wiring opening pro- vided and into the unit control box as shown in Figures 6 & 7.
