Disconnect Switch with External Handle
Units come equipped with a factory mounted
disconnect switch with an externally mounted handle.
This allows the operator to disconnect power from the
unit without having to open the control panel door. The
handle has three positions:
• “ON” - Indicates that the disconnect switch is
closed, allowing the main power supply to be
applied at the unit.
