TUBING PACKAGE INSTALLATION - Before install­
ing, inspect the package contents. If any parts are missing
or damaged, file a claim with the shipping company and
notify your Carrier representative A field supplied 3/8-in.
conduit (Greenfield conduit recommended) is required
according to UL/CSA (Underwriters’ Laboratories/
Canadian Standards Association) code for the FCPS field
wiring. Field supplied 3/8-in. conduit connectors are re­
quired for connection to the junction box.
100% Coil Circuiting Applications: 054, 064 Units
/. Piping — Refer to Fig. 10 and 14 for field piping de­
tails for 100% coil circuiting. Note that tubes 15 and 22 re­
quire cuts on the longer legs of the tubes Two 7/8-in. OD
tubes, approximately 3 in. (76.2 mm) long, must be cut
from the remaining tubes (tubes 21, 23, or 25) and brazed
between the tees (item 8) and coil header stubs. The re­
maining tubes are not used in this application and may be
discarded.
2. Install Fan Cycle Pressure Switches and Clamps — Braze 2
valve core bodies (item 5) to designated hole locations on
tubes 19 and 22. Insert valve cores (item 6), into valve core
bodies by threading into place and tightening to 1.5 to
3 in.-lb (169.5 to 339 mN-m). Install FCPSl and FCPS2
(item 7) at designated locations on tubes 19 and 22. Cut
the 3/8-in. field-supplied FCPS conduit to fit between each
FCPS location and the junction box on the unit. Figure 13
shows a typical installation of the conduit. Feed FCPS wires
through each conduit and secure at the switch using each
conduit connector. See Fig. 15. Secure the conduit at the
Junction box with 3/8-in. field-supplied conduit connectors.
Wire FCPSl and FCPS2 according to Fig. 16. Clamp hot
gas line, tube 27, at the location specified in Fig. 14 using
the 1 5/8-in. clamp (item 4) and the 2 screws supplied. Clamp
the liquid line, tube 24, using the 1 1/8-in. clamp (item 2)
and the 2 screws provided.
50/50% Coil Circuiting Applications: 054 and 064 units
1. Piping — Refer to Fig. 10 and 17 for field piping de­
tails for 50/50% coil circuiting. Note that tubes 21 and 22
require cuts on the longer legs of the tubes. Two 7/8-in.
OD tubes, approximately 3 in (72.6 mm) long, must be
cut from the remaining tubes (21,25, 26, or 29) and brazed
between the tees (item 8) and coil header stubs. The re­
maining tubes are not used in this application and may be
discarded.
2. Install Fan Cycle Pressure Switches and Clamps — Braze 2
valve core bodies (item 5) to designated hole locations on
tubes 19 and 22 Insert valve cores (item 6) into valve core
bodies by threading into place and tightening to 1.5 to
3 in.-lb (169.5 to 339 mN-m). Install FCPSl and FCPS2
(item 7) at designated locations on tubes 19 and 22. Cut the
field-supplied 3/8-in. FCPS conduit to fit between each FCPS
location and the junction box on the unit. Figure 13 shows
a typical installation of the conduit. Feed FCPS wires through
each conduit and secure at the switch using each conduit
connector. See Fig. 15. Secure the conduit at the junc­
tion box with 3/8-in. field-supplied conduit connectors. Wire
FCPSl and FCPS2 according to Fig. 16. Clamp hot gas
lines, tube 15, at the location specified in Fig. 17 using the
two 1 3/8-in. clamps (item 3) and 4 screws provided. Clamp
the liquid lines, tubes 21 and 23, using the two 7/8-in. clamps
(item 1) and the 4 screws provided.
66/34% Coil Circuiting Applications: 054 and 064 Units
NOTE: To operate the 054 and 064 condenser units with
66/34% coil circuiting, an accessory fan control kit is
required. Refer to fan control kit installation instruc­
tions for more information.
1. Piping — Refer to Fig. 10 and 18 for field piping de­
tails for 66/34% coil circuiting. Note that tube 16 requires
cuts on the longer leg of the tube. Tube 16 is used in the
two specified locations. A 7/8-in. OD tube, approximately
3 in. (72.6 mm) long, must be cut from the remaining tubes
(23 or 26) and brazed between the tee (item 8) and coil
header stub. The remaining tubes are not used in this ap­
plication and may be discarded
2. Install Fan-Cycle Pressure Switches and Clamps — Braze 3
valve core bodies (item 5) to designated hole locations on
tubes 19, 21, and 22. Insert valve cores (item 6) into valve
core bodies by threading into place and tightening to 1.5 to
3 in.-lb (169.5 to 339 mN-m). Note that the accessory fan
control kit is required for this coil circuiting. An extra FCPS
and valve assembly is provided with the kit. Install FCPSl,
FCPS2, and FCPS4 (item 7) at designated locations on tubes
19, 21, and 22. Cut the field-supplied 3/8-in. FCPS conduit
to fit between each FCPS location and the junction box on
the unit. See Fig. 13 for typical conduit installation. Feed
FCPS wires through each conduit and secure at the switch
using each conduit connector. See Fig. 15 Secure the con­
duit at the junction box with 3/8-in., field-supplied conduit
connectors. Wire FCPSl, FCPS2, and FCPS4 according to
Fig. 16. Note that FCPS2 and FCPS4 are wired in parallel.
Fan 4 is shared by the 34% and 66% refrigeration circuit;
the fan switches on if either circuit requires it. At the loca­
tion specified in Fig. 18, clamp hot gas lines, tubes 15 and
30, using a 1 3/8-in. clamp (item 3) and a 1 1/8-in. clamp
(item 2) with the 4 screws supplied. Clamp the liquid lines,
tubes 21 and 25, with 7/8-in. clamps (item 1) and 4 screws
provided.
100% Coil Circuiting Applications; 074 Units
1 Piping — Refer to Fig. 10 and 19 for field piping
details for 100% coil circuiting. Note that tube 16 requires
a cut on the longer leg of the tube. Two 7/8-in. OD tubes
approximately 3 in. (72.6 mm) long, must be cut from
the remaining tubes (22 or 23) and brazed between the tees
(item 9) and coil header stubs. The remaining tubes are not
used and may be discarded.
2 Install Fan Cycle Pressure Switches and Clamps — Braze 2
valve core bodies (item 6) to designated hole locations on
tubes 20 and 24. Insert valve cores (item 7) into valve core
bodies by threading into place and tightening to 1.5 to
3 in.-lb (169 to 339 mN-m). Install FCPSl and FCPS2
(item 8) at designated locations on tubes 20 and 24. Cut the
3/8-in. field-supplied FCPS conduit to fit between each FCPS
location and the junction box on the unit. See Fig. 13 for
typical conduit installation. Feed FCPS wires through each
conduit and secure at the switch using each conduit con­
nector. See Fig. 15. Secure the conduit at the junction
box with 3/8-in. field-supplied conduit connectors. Wire
FCPSl and FCPS2 according to Fig. 20. Clamp hot gas
line, tube 28, using 2 1/8-in. clamp (item 5) at the location
specified in Fig. 19 with the 2 screws supplied. Clamp the
liquid line, tube 25, using 1 1/8-in. clamp (item 2) and the
