Electrical Wiring
a�
Once the unit is installed, refer to the wiring
diagrams which are provided on the backside of the
control box covers�
b�
Units are completely internally wired at the factory
for commonly rated supply voltages� Check unit data
tags for required voltage, wire and fuse sizing� The
factory wiring terminates in two boxes; one each
in the evaporator and condensing sections� These
control boxes are located behind the outer access
panels� Each is supplied with an individual control
box cover with a wiring diagram attached inside�
c�
All the units are provided with terminal blocks�
d�
The power wiring to the unit is to be brought through
one of the available holes for the unit electrical
power connection(s)�
e�
The control wiring is brought through the holes
provided in the unit�
f�
Supply wiring must comply with all National or Local
codes� The power supply must be suitably fused for
wire protection�
g�
Use copper conductors only� The unit must be earth
grounded using the ground lug provided in the
electrical box� Metal conduit is not an acceptable
ground�
h�
Run the low voltage wiring from the thermostat to the

Split Systems
If the unit was ordered for a split system application each
section will contain male resealable refrigerant fittings. Install
the mating female fittings and field supplied tubing per the
instructions that follow� Note that Optional Interconnect Kits
are required for each circuit and external Hot Gas Bypass
circuit�
Separation Of Sections
If the unit is to be installed as a split system, the following
steps must be carefully followed in performing the separation�
1�
Remove evaporator access panel�
2�
Using an open-end wrench and turning counter-
clockwise, disconnect the female half of the self-
sealing couplings on both the suction and discharge
lines� These are located in the bottom left area of the
evaporator section� When there is a hot gas bypass
option, that connection is to the right of the self-sealing
coupling connections� There is one suction line, one
liquid line, and one hot gas by-pass line (option) for
each compressor�
