Appendix B: Electrical Wiring for 265 Volt Models
NOTE: It is recommended that the PXSB subbase assembly, the PXCJ conduit kit and the PXDS disconnect switch be installed on all
hardwired units. If installing a flush-floor mounted unit, make provisions for all the line voltage power leads and conduit to be removed for
ease of maintenance and service to the chassis.
To install the line voltage power leads and conduit to the chassis, follow the instructions below.
1. Remove the four control box retaining screws (A) and open
the control box.
2. Pull the chassis power lead wires (B) (located on the bottom-
right side of the control box) through the plastic bushing so
they are located inside the control box.
3. Remove the plastic bushing.
4. Route the line voltage power leads through the hole where
the plastic bushing was located, and secure its conduit (use a
1/2" straight conduit connector, with the locknut on the inside
of the control box.)

5. Make the appropriate electrical connections within the control
box, then secure the box on the chassis. Detailed instructions
are included with the installation instructions for the conduit
kit (PXCJ).
6. Route the line voltage power conduit from the control
box straight down the right front to the bottom side of the
chassis. This will allow the front cover to be installed without
interference with the electrical conduit.
