TRANSPORTATION DAMAGE
File claim with shipping company if shipment is
damaged or incomplete.
Unpackaging Unit — Move condensing unit to final
location. Open carton at end marked “compressor
end.” Slide unit from carton taking special care to
not damage service valves or grilles.
PRELIMINARY SURVEY
Consult local building codes and National
Electrical Code (NEC) for special installation
requirements.
When installing unit, allow sufficient space for
air flow clearance, wiring, refrigerant piping and
servicing unit. Position unit so water from roof or
eaves does not flow directly on top of unit.
Install unit on a solid, level mounting pad. Unit
can be attached to pad with a mastic adhesive or
by drilling holes in base pan for 1/4-in. mounting
bolts. Do not block base pan water drainage holes.
38GS,CC,CE Condensing Units Connected to
Carrier Matched Evaporators with Carrier Acces­
sory Tubing
— Check system refrigerant charge
when tubing lengths are above or below 25 feet.
See Refrigerant Charging (page 10) for details.
38GS,CC,CE Condensing Units Connected to Non-
Carrier Evaporators
— Check refrigerant charge
when condensing unit is added to a system in
which other than a Carrier approved evaporator is
being used or where the evaporator has been
previously installed. Field-supplied refrigerant pip­
ing must be in accordance with Field-Supplied
Piping Data, Table 3.
Where indicated on Table 3 for 38GS,CE units,
install a liquid line filter-drier and accessory crank­
case heater on condensing unit. (Filter-drier is
factory supplied on CE045,005 units.) Accessory
start capacitor and relay also required on 38GS
units, but not normally required on 38CE units.
See Compressor Service (page 7). All above items
are standard or not required for 38CC units.
Use an evaporator coil with a bleed-type ex­
pansion device. If coil does not have a bleed-type
expansion device it may be necessary to add an
accessory start capacitor and relay to condensing
unit. This would require removing compressor start
thermistor (PTC device) on units so equipped.
