*Bushings required.
D. Install Liquid Line Solenoid Valve (Optional) — Capacity
Control
If 2-step cooling is desired, place a solenoid valve in the loca-
tion shown in Fig. 7.
E. Make Piping Connections
Do not remove runaround loop from suction and liquid line
stubs in the compressor compartment until piping connec-
tions are ready to be made. Pass nitrogen or other inert gas
through piping while brazing to prevent formation of copper
oxide.
1. Open service valves:
a. Discharge service valve on compressor.
b. Suction service valve on compressor.
c. Liquid line valve.
2. Remove

-in. flare cap from liquid valve Schrader
port.
3. Attach refrigerant recovery device and recover hold-
ing charge.
4. Remove runaround loop.
5. Install a field-supplied liquid moisture indicator in
the piping immediately leaving outdoor unit.
6. If necessary, install field-supplied thermostatic
expansion valve(s) (TXVs) in air handler.
If 2 TXVs are installed and two-step cooling is desired,
install field-supplied capacity control liquid line solenoid
valve ahead of the upper TXV (see Fig. 7).
F. Provide Safety Relief
A fusible plug is located on the compressor crankcase or in
the liquid line (Fig. 8). Do not cap this plug. If local code
requires additional safety devices, install them as directed.
IV. INSTALL ACCESSORIES
Field install accessories such as low-ambient control before
proceeding with wiring. Refer to the instructions shipped
with the accessory.
V. COMPLETE ELECTRICAL CONNECTIONS
A. Power Wiring
Unit is factory wired for voltage shown on nameplate. Pro-
vide adequate fused disconnect switch within sight from unit
and readily accessible from unit, but out of the reach of chil-
dren. Lock switch open (off) to prevent power from being
turned on while unit is being serviced. Disconnect switch,
fuses, and field wiring must comply with national and local
code requirements. See Tables 6A-6C.
Route power wires through opening in unit end panel to con-
nection in unit control box as shown on unit label diagram
and in Fig. 9. Unit must be grounded.
Affix crankcase heater warning sticker to unit disconnect
switch.
B. Control Circuit Wiring
Control voltage is 24 v. See Fig. 10 and unit label diagram for
field-supplied wiring details. Route control wires through
opening in unit end panel to connection in unit control box.
C. Control Transformer Wiring (569D, 576C, 569F Units
Only)
On multivoltage units, check the transformer primary wir-
ing connections. See Fig. 11 or refer to unit label diagram.
If unit will be operating at 208-3-60 power, remove black
wire (BLK) from the transformer primary connection
labelled “230” and move it to the connection labelled “208”.
See Fig. 11.
