Hard Wire Kit

Model: AYAGALA01

Description

Hard Wire Junction Box (Direct Wire Sub-Base) The hard wire
junction box kit is used to hard 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 hard wire 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 securing the
conduit to the unit cabinet at the incoming power opening.

An optional 208/230V or 265V power switch assembly is
available for use with the hard wire junction box or subbase.
The switch provides a POWER ON/OFF function at the unit
as required by some electrical codes.
A replacement junction 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

EIectrical 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 components for attaching
the junction box to the wall or door.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects
before servicing. Follow proper lockout/tagout procedures to
ensure the power can not be inadvertently energized. Failure
to disconnect power before servicing could result in death or
serious injury.

Important Note:

The unit OFF switch does not disconnect all electrical power
to this unit.

CAUTION

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of
conductors. Failure to use copper conductors may result in
equipment damage.

Important Note:

All wiring must comply with applicable
local and national codes. Types and location of disconnect
switches must comply with all applicable codes.

1. Remove the cover plate from the junction box
2. Mount the junction box to the wall or floor within 28" (711 mm)

of the lower right corner of the wall sleeve.

3. If a disconnect switch is to be used, make electrical

connections to it and mount the switch in the junction box.
Refer to the Power Switch Installation Instructions.

4. Remove control panel assembly by removing the two screws

holding control panel in place. Rotate the panel forward.

5. Disconnect the power cord leads from all electrical connections

including the ground wire.

6. Remove the power cord clamp and the power cord from the

unit.

7. For 208/230-volt units, remove and discard the white lead from

the wire assembly. For 265-volt units, remove and discard the
red lead from the wire assembly.

8. Remove the retaining ring from the threaded portion of the

straight conduit clamp. Insert the three wires into the metal box
through one of the two openings in the box. Replace the hole
cover grommet into the unused hole to prevent objects from
entering the box.

9. Replace the retaining ring back on the conduit clamp inside the

metal box and tighten the ring securely.

10. Insert the three wires extending from the metal box into the

incoming power opening on the unit so that approximately 20"
(508 mm) of the wires protrude through the opening.

11. Attach the metal box to the chassis with the two screws

provided. See Figure 45.

12. Insert the wire tie into the 1/4" diameter hole located just

above the incoming power opening. Tie all wires together
securely with the wire tie. See Figure 46.
