For sizes 075-095:
1. The FCPS wires should be routed through bushing
located in bottom of control box as shown in Fig. 24.
2. Remove the factory-supplied red jumper wire between
terminals 3 and 4 of TB3.
3. The FCPS1 and FCPS2 switches are wired in Parallel
into the control circuit as shown in Fig. 26. The VIO
and ORN wires are wired together when shipped from
the factory. The connectors should be removed and
one end of the FCPS wired together with the RED and
ORN wire using wire nuts and the other end connected
to TB3 terminal 4.
For sizes 115-130:
1. The FCPS wires should be routed through bushing
located in bottom of control box as shown in Fig. 24.
2. Remove the red jumper wire between terminals 3 and
4 of TB3 that is supplied from the factory. This is
installed for test purposes only.
3. Disconnect the VIO and ORN FCPS1 and FCPS2
wires that are connected together when shipped from
the factory.
4. Connect FCPS1 between to the violet wire labeled
FCPS1 and TB3 terminal 4 per Fig. 27.
5. Connect FCPS2 between to the orange wire labeled
FCPS2 and pink wire labeled FC4 coil per Fig. 27.
Step 5 — Check Condenser Fans —
Each fan is
supported by a formed wire mount bolted to a fan deck and
covered with a wire guard.
METAL FANS — The exposed end of fan motor shaft is pro-
tected from weather by grease and a rubber boot. If fan motor
must be removed for service or replacement, be sure to re-
grease fan shaft and reinstall fan guard. For proper perfor-
mance, fan web should be 0.32 in. (8 mm) below top of orifice
on the fan deck to top of the fan hub. (See Fig. 28.) Tighten set
screws to 15 ± 1 ft-lb (20 ± 1.3 N-m). Figure 28 shows the
proper position of mounted fan.
LOW SOUND FAN — A shroud and a wire guard provide
protection from the rotating fan. The exposed end of the fan
motor shaft is protected from weather by grease. If fan motor
must be removed for service or replacement, be sure to re-
grease fan shaft and reinstall fan guard. The fan motor has a
step in the motor shaft. For proper performance, fan should be
