PIPING CONNECTIONS
Condensing units can be connected to evap­
orator sections using Carrier accessory tubing
package or field-supplied tubing of refrigerant
grade.
(Accessory tubing not available for
38GS060, 38CC060.) See Table 2 for accessory
tubing sizes and Table 3 for recommended field-
supplied tubing sizes. Where evaporator is 20 ft or
more below condensing unit, reduce liquid line size
one diameter (min 1/4-in. OD).
A capacity reduction will result if accessory
tubing is used in 38CE045,005 systems. For
example, when a 25 ft accessory tubing package is
used, there will be a capacity reduction of 3 3/4%
on 38CE045 and 5% on 38CE005 systems. For
maximum capacity from these systems, use tubing
sizes shown in Table 3.
When other than 25 ft of interconnecting
tubing is used, follow special requirements de­
scribed in Refrigerant Charging. Do not use less
than 10 ft of liquid line. Do not cut 5/16-in. or
1/4-in. liquid line. Bend or coil to fit.
Do not use damaged or contaminated tubing. If
accessory tubing package or evaporator section has
been open for more than 15 seconds per connec­
tion, evacuate or purge evaporator coil and tubing
system (use field-supplied refrigerant, not unit
refrigerant). Always evacuate or purge if field-
supplied tubing is used.
Before Connecting Unit Piping, consider the
following:
38CE045,005 AND 38CC UNITS - A filter-drier
package is shipped with these units. Included with
filter-drier are 2 short length tubing assemblies that
are equipped with flare and/or Compatible Fit­
tings. Use tubing assemblies to install filter-drier
into system liquid line at evaporator or condensing
unit. See Fig. 2. Connect tubing assembly A (90°
assembly) to evaporator or condensing unit liquid
line Compatible Fitting. Complete the filter-drier
installation as shown.
