Appendix A: 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.
