Carrier 09DK054-084 - Manual (Page 17)

6113?)% Coil Circuiting Applications: 084 Units
NOTE: To operate 084 condenser units with 67/33% coil
circuiting, an accessory fan control kit is required.
See
accessory installation instructions for more
information.
1. Piping — Refer to Fig. 9 and 23 for field piping details
for 67/33% coil circuiting. Note that tubes 17 and 20
require a cut on the longer leg of the tubes. Tube 17 will
be used in the two locations specified. Also, a 7/8-in. OD
tube, approximately 3 in. (72.6 mm) long must be cut from
the remaining tubes (22 or 27) and brazed between the tee
(item 9) and coil header stub. The remaining tubes are not
used in this application and may be discarded.
2 Install Fan Cycle Pressure Switches and Clamps — Braze 3
valve core bodies (item 6) to designated hole locations on
tubes 20, 23, and 24. Insert valve cores (item 7) into valve
core bodies by threading into place and tightening to 1.5 to
3 in.-lb (169.5 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 8) at designated loca­
tions on tubes 20, 23, and 24. Cut the 3/8-in. field-supplied
FCPS conduit at a desired length to fit between each FCPS
location and the junction box on the unit. See Fig. 11 for
typical conduit installation. Feed FCPS wires through each
conduit and secure at the switch by utilizing each conduit
connector. See Fig. 13. Secure the conduit at the junction
box with 3/8-in. field-supplied conduit connector. Wire FCPSl,
FCPS2, and FCPS4 according to Fig. 18. Note that FCPS2
and FCPS4 are wired in parallel. Fan 4 is shared by the
33% and 67% refrigeration circuit. If either circuit needs
the fan to be on, it will be on. At the location specified in
Fig. 23, clamp hot gas lines, tube 15 with a 1 3/8-in. clamp
(item 3) and tube 16 with a 1 5/8-in. clamp (item 4) with
the 4 screws supplied Clamp the liquid lines, tube 23 with
a 7/8-in. clamp (item 1) and tube 25 with a 1 1/8-in. clamp
(item 2) with 4 screws supplied.
THREE AND FOUR COIL SPLIT, COIL CIRCUITING
APPLICATIONS; 054-084 UNITS
NOTE: To operate 054-084 condenser units with the 3
and 4 coil split coil circuiting, the fan control kit is re­
quired. See accessory installation instructions for more
information.
1. Piping — Piping is not provided in the tubing package
for these coil circuiting options. Tubing is field fabricated
and installed, according to the coil circuiting shown in
Fig. 8. For pipe sizing information, refer to Refrigerant Line
Sizing, page 18. To secure the piping, it should be routed
to the brackets supplied on the unit.
