TRANSPORTATION DAMAGE
File claim with shipping company if shipment is
damaged or incomplete.
SKID REMOVAL
Move condensing unit to final location. Remove top
grille. Reach between fan blades and remove 1/4-in.
hex head screws holding unit to skid. On the 145, 105,
106 units, remove the two compressor shipping brackets
attached to top of compressor and sides of unit.
Consult local building codes for special installa­
tion requirements.
When installing unit, allow sufficient space for
air-flow clearance, wiring, refrigerant piping and
servicing unit. NEC minimum requirement is 3 ft
(see Fig. 1). Position unit so water from roof or
eaves will not pour directly on top of unit.
Install unit on a solid, level mounting pad.
Position tie-down bolts in pad. Any two holes in
unit base may be used to fasten unit to pad.
38GC,GF Condensing Units are designed for appli­
cation with any Carrier or other evaporator of
proper capacity. Install each unit in accordance
with Refrigerant Piping Data, (Table 4) and the
following special requirements.
Where refrigerant line lengths exceed 25 ft, it is
recommended that a liquid line filter-drier, crank­
case heater and accessory start capacitor with relay
be added to condensing unit.
Liquid line filter-drier and crankcase heater are
factory installed on 38GF units. Start capacitor
with relay is available as an accessory for
38GC101, 102, 103 and 38GF102; factory in­
stalled on remaining sizes.
When evaporator is below condensing unit,
reduce liquid line size one diameter (min 114-in.
OD).
PIPING CONNECTIONS
38GC,GF Condensing Units can be connected to
evaporator sections using Carrier accessory pre­
charged tubing or field-supplied tubing of refrig­
erant grade. (Accessory tubing not available for
38GF106.) See Table 3 for accessory tubing sizes
and Table 4 for recommended field-supplied tubing
sizes. When over 25 ft of interconnecting tubing is
used, follow special requirements described above
in Preliminary Survey. Do not use damaged or
contaminated tubing. Do not cut 3/8-in. OD liquid
line to a length shorter than 10 ft. Bend or coil to
fit. When precharged tubing or evaporator section
has been open for more than 15 seconds per
connection, evacuate or purge evaporator coil and
tubing system (use field-supplied refrigerant, not
unit refrigerant). If necessary, refer to Carrier
System Design Manual, Part 3, for standard piping
techniques.
38GC,GF Connection Procedure — When making
piping connections, be sure to provide clearance at
unit for electrical connections.
Connect refrigerant liquid and suction lines to
condensing unit (Fig. 1). Unit Compatible Fitting
permits two methods of refrigerant line connec­
tion. mechanical (quick-connect) or sweat
connection.
38GF106 UNITS — Remove suction line adapter
taped to compressor shipping bracket and connect
to suction line Compatible Fitting. Sweat connect
refrigerant suction line to adapter. Connect liquid
refrigerant line to unit.
