ELECTRICAL WIRING

Follow local electrical codes when making electrical
connections. Units are completely factory wired for nor-
mal supply voltages (ie.208-230, 460, 575V/3Ph/60Hz)
Confirm unit specifications by checking unit data plate.
All electrical components are accessible through an
independent electrical panel located on the "front" face
of the condensing section. The electrical control boxes
are located behind outer access panels. The con-
denser section electrical cover is installed with wiring
diagrams on the inside, which must be opened to be
read.

Provide individual power disconnects for each unit, or
each section in the case of split applications. Install a
secure ground to both evaporator and condenser. If
canvas flexible joints are used on ductwork, install a
ground wire to the ductwork as well.

  

IMPORTANT:

 All wiring must comply with applicable

local and national codes (NEC). Type and location of
disconnect switches must comply with all applicable
codes.

For low voltage thermostat wiring, 18 gauge wire may
be used for up to 50 feet lengths. Low voltage runs up
to 125 feet require 16-gauge wire.

  

Disconnect and lock out power when servic-
ing unit. unit may start automatically if power
is not disconnected. Failure to do so may
result in personal injury or death due to elec-
trical shock.
