RIG MACHINE COMPONENTS — Refer to instructions
on page 5, Fig. 6-8, and Carrier certified drawings for ma-
chine component disassembly.
IMPORTANT: Only a qualified service technician should
disassemble and reassemble the machine. After reas-
sembly, the machine must be dehydrated and leak tested.
When rigging components separately, the open drive
(17EX) motor must be removed to avoid overturning.
Do not attempt to disconnect flanges while the machine
is under pressure. Failure to relieve pressure can result
in personal injury or damage to the unit.
Before rigging the compressor, disconnect the wires
leading from the power panel to the control center at the
power panel.
NOTE: Wiring for sensors must be disconnected. Label each
wire before removal (see Carrier certified drawings).
Detach all transducer and sensor wires at the sensor, then
clip all wire ties necessary to remove the wires from the heat
exchangers.
