Connection to the Power Source
2
CAUTION:
This chamber should be connected to the AC power source by a qualified
electrician who is familiar with industrial plant wiring.
The Main Disconnect Switch on the front panel removes primary power to the entire chamber.
All branch circuits on the load side of the Main Disconnect Switch are individually fused.
However, your local electrical code may require a separate disconnect switch within sight of the
chamber.

Input Access Hole. This hole is in the corner of the partition which separates the compressor
compartment from the electrical compartment. Three tie points are provided on the side of
the chamber to secure the input wiring with provided tie-wraps.
