*For maximum capacities, use suction line sizes recommended in
Table 3 If accessory tubing package is used on 38VH004,045,
005 units, a reduction in capacity can result Field-supplied
1-1/8 in suction line is recommended with all 28VFI coil
installations
fSuction line is insulated and has a 90 degree bend at one end
JFor 5/8-in evaporator connection, cut off 3/4-in end
NOTE Do not cut 3/8-in OD liquid lines to a length shorter than
10 feet Do not cut 5/16-or 1/4-in liquid line Do not cut 7/8-in
OD suction lines
Do not use damaged or contaminated tubing.
Always evacuate or purge evaporator coil and
tubing system. When purging, use field-supplied
refrigerant, not unit holding charge refrigerant.
When making tubing connections, be sure to pro
vide clearance at unit for electrical connections.
REPLACE THE ACCURATER™ REFRIGER
ANT CONTROL PISTON IN THE INDOOR
COIL, if required, before connecting refrigerant
lines. See Carrier Cooling System Optimization,
page 2.

1-1/8 in. field-supplied suction line, remove suction
line adapter taped to compressor suction line. Sweat
connect refrigerant suction line to 1-1/8 in. end of
adapter. Be sure to provide a heat sink at the service
valve to prevent damage during sweating operation.
Connect 3/4-in. end of adapter to unit suction line
Compatible Fitting. Connect liquid refrigerant line
to unit. When a 7/8-in. field-supplied suction line
is used, provide a field-supplied 3/4-in. to 7/8-in.
suction line adapter. (Not necessary if 38LS acces
