A disconnect must be utilized for these units. When installing

a disconnect, refer to Figure 4 for the recommended mount-

ing location.

Avoid damage to internal components if drilling

holes for disconnect mounting.

NOTE: Since not all local codes allow the mounting of a dis-

connect on the unit, please confirm compliance with

local code before mounting a disconnect on the unit.

NOTE: This unit does not require a heat pump thermostat.

It is designed to work with a standard two-stage

cool, two-stage heat thermostat; however, the ther-

mostat must provide a "G" signal when there is a

call for "W1".

Refer to Figures 17, 18 and 19 for typical field wiring and to

the appropriate unit wiring diagram mounted inside control

doors for control circuit and power wiring information.

When connecting electrical power and control wiring

to the unit, water-proof connectors must be used so

that water or moisture cannot be drawn into the unit

during normal operation. The above water-proofing

conditions will also apply when installing a field sup-

plied disconnect switch.
