Field High-Voltage Wiring
NOTE: Use blue wire for 3-phase units only.
Fig. 11 — High- and Control-Voltage Connections
Use no. 18 American Wire Gage (AWG) color-coded, insu-
lated (35 C minimum) wires to make the control voltage con-
nections between the thermostat and the unit. If the thermo-
stat is located more than 100 ft from the unit (as measured
along the control voltage wires), use no. 16 AWG color-coded,
insulated (35 C minimum) wires.
Standard Connection
Remove knockout hole located in the flue panel adjacent to
the control access panel. See Fig. 2 and 3. Remove the rubber
grommet from the installer's packet (included with unit) and
install grommet in the knockout opening. Provide a drip loop
before running wire through panel.
Run the low-voltage leads from the thermostat, through the
inlet hole, and into unit low-voltage splice box.
Locate five 18-gage wires leaving control box. These low-
voltage connection leads can be identified by the colors red,
green, yellow, brown, and white. (See Fig. 11.) Ensure the leads
are long enough to be routed into the low-voltage splice box
(located below right side of control box). Stripped yellow wire
is located in connection box. Route leads through hole in bot-
tom of control box and make low-voltage connections as shown
in Fig. 11. Secure all cut wires, so that they do not interfere
with operation of unit.
D. Heat Anticipator Setting
The room thermostat heat anticipator must be properly ad-
justed to ensure proper heating performance. Set the heat
anticipator, using an ammeter between the W and R termi-
nals to determine the exact required setting.
NOTE: For thermostat selection purposes, use 0.18 amp for
the approximate required setting.
Failure to make a proper heat anticipator adjustment will
result in improper operation, discomfort to the occupants of
the conditioned space, and inefficient energy utilization; how-
ever, the required setting may be changed slightly to provide
a greater degree of comfort for a particular installation.
E. Transformer Protection
The transformer is of the energy-limiting type. It is set to
withstand a 30-second overload or shorted secondary
condition.

WARNING: Failure to observe the following warn-
ings could result in serious personal injury:
1. Follow recognized safety practices and wear protec-
tive goggles when checking or servicing refrigerant
system.
2. Do not operate compressor or provide any electric
power to unit unless compressor terminal cover is in
place and secured.
3. Do not remove compressor terminal cover until all
electrical sources are disconnected.
4. Relieve and recover all refrigerant from system be-
fore touching or disturbing anything inside termi-
nal box if refrigerant leak is suspected around com-
pressor terminals.
5. Never attempt to repair soldered connection while
refrigerant system is under pressure.
6. Do not use torch to remove any component. System
contains oil and refrigerant under pressure. To re-
move a component, wear protective goggles and pro-
ceed as follows:
a. Shut off gas supply and then electrical power to
unit.
b. Relieve and reclaim all refrigerant from system
using both high- and low-pressure ports.
c. Cut component connecting tubing with tubing cut-
ter and remove component from unit.
d. Carefully unsweat remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.
Proceed as follows to inspect and prepare the unit for initial

start-up:

1. Remove access panel.
2. Read and follow instructions on all WARNING, CAU-
TION, and INFORMATION labels attached to, or shipped
with, unit.
3. Make the following inspections:
a. Inspect for shipping and handling damages such as
broken lines, loose parts, disconnected wires, etc.
b. Inspect for oil at all refrigerant tubing connections
and on unit base. Detecting oil generally indicates a
refrigerant leak. Leak-test all refrigerant tubing con-
nections using electronic leak detector, halide torch,
or liquid-soap solution. If a refrigerant leak is de-
tected, see Check for Refrigerant Leaks section on
page 15.
c. Inspect all field- and factory-wiring connections. Be
sure that connections are completed and tight.
d. Inspect coil fins. If damaged during shipping and han-
dling, carefully straighten fins with a fin comb.
