3.3.2 - Rig machine components
If the unit is disassembled for rigging, the weight of each
machine element must be known: motor, compressor, heat
exchangers with and without refrigerant charges, electrical
equipment, special waterboxes, isolation valves, etc. This
information is available on the dimensional drawing supplied
with the machine.
Follow the instructions given below and refer to the views
of the unit and Figs. 7 to 10.
IMPORTANT: Only a qualified service technician should
perform this operation.
WARNING: 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.
CAUTION: Before rigging the compressor, disconnect all
wires entering the control box.
NOTE: If the cooler and condenser vessels must be
separated, the heat exchangers should be kept level by
placing a support plate under the tube sheets. The support
plate will also help to keep the vessels level and aligned
when the vessels are bolted back together.
NOTE: Wiring must also be disconnected. Label each
wire before removal (see Carrier Certified Prints). In
order to disconnect the starter from the machine, remove
wiring for the oil pump, oil heater, control wiring at the
control box, and the main motor leads at the starter lugs.
Remove all transducer and sensor wires at the sensor.
Clip all wire ties necessary to pull heat exchangers apart.

Weights are approximate and include the weight of the refrigerant, water,
nozzle-in-head waterboxes and the thickest pipes.
For the 19XRV machines the weight of the power
equipment must be added to the net machine weights -
please refer to chapter 17.3.
