The compressor is heavy. To avoid bodily injury, lift
the compressor only by using cables or slings. Do not
lift the compressor using threaded eyebolts. Metric threaded
eyebolts are provided only for lifting individual com-
pressor castings.
IMPORTANT: Only a qualified service technician
should disassemble and reassemble the machine. After
reassembly, the machine must be dehydrated and leak
tested.
RIG MACHINE COMPONENTS — Refer to instructions
below, Fig. 8-12, and Carrier certified prints for machine
disassembly.
Do not attempt to cut refrigeration lines or disconnect
flanges or fittings while machine is under pressure. Cut-
ting lines or disconnecting flanges or fittings can result
in personal injury or damage to the unit. Be sure both
refrigerant and oil charge are removed from the ma-
chine before separating the components.
NOTE: If the cooler and condenser vessels must be sepa-
rated, the heat exchanger separation feet must be unbolted,
rotated, and rebolted in order to keep each heat exchanger
level. See Fig. 4, 5, and 8-12.
NOTE: Sensor wiring must be disconnected. Label each wire
before removal (see Carrier certified prints). Remove all trans-
ducer and thermistor wires at the sensor. Clip all wire ties
necessary to remove the wires from the heat ex-
changers. Remove the control wiring and oil heater wiring
(Frame 1 and 2 machines) at the power panel and the main
motor leads at the starter lugs before disconnecting the starter
from the machine.
*Carrier recommends that ‘‘I’’ Beam Spreader Bars be field supplied and installed.
