place. Just remove the screws and the front panel, feed your supply lines in through the conduit
nipple and wire-nut the electric supply wires to the three connections already in the junction box
(four connections if three phase). To complete electrical hookup, connect Heat Pump by electrical
ies)
to a dedicated AC power supply branch circuit equipped with the proper circuit breaker,
disconnect or time delay fuse protection.
Disconnect - A disconnect means (circuit breaker , fused or un-fused switch) should be located
