Carrier 17 Ð Typical 19EX Installation, Local Interface Display Control Panel

RIG MACHINE COMPONENTS Ð Refer to instructions on page 5, Fig. 6-8, and Carrier certi®ed drawings for ma- chine component disassembly.

IMPORTANT: Only a quali®ed 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 ¯anges 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 certi®ed drawings).

Detach all transducer and sensor wires at the sensor, then clip all wire ties necessary to remove the wires from the heat exchangers.
