Hard Wire
Description
Hardwire Junction Box (Direct Wire Sub-Base)
The hardwire junction box kit is used to direct wire the unit
when it is not desirable to use the standard unit subbase or
the unit power cord. The junction box provides a protected
enclosure for electrical connections as required by some
electrical codes.
The hardwire junction box is intended to be mounted on the
floor or the adjacent wall.
The junction box is furnished with approximately 2-1/2 feet
of 1/2 inch flexible steel conduit and a metal box for secur-
ing the conduit to the unit cabinet at the incoming power
opening.
An optional 230/208V or 265V power switch assembly is
available for use with the hardwire junction box or subbase.
The switch provides a POWER ON/OFF function at the unit
as required by some electrical codes. A replacement junc-
tion box cover plate is provided with each switch kit. For
additional information, refer to the Power Switch Installation
Instructions.
Junction Box Kit Installation and Wiring Procedure
The installation and servicing of this equipment should be
performed by qualified, experienced technicians.
Electrical connections at the unit must be made after the
unit chassis is installed in the wall sleeve.
The installer must determine and supply the mounting com-
ponents for attaching the junction box to the wall or floor.
