The power supply lines must be run in weather-tight
conduit to the disconnect and into the side of the unit
control box. Provide strain relief for all conduit with
suitable connectors.
Provide flexible conduit supports whenever vibration
transmission may cause a noise problem within the
building structure.
1. Remove the Control/Heat access panel. Pass the
power wires through the Power Entry hole in the
end of the unit. See
2. Connect the high voltage wires to the appropriate
contactor terminals. Single phase units use a two
(2) pole contactor and three phase units use three
(3) pole contactor. Connect the ground to the
ground lug on the chassis. See
Ensure all connections are tight.
