RIG MACHINE COMPONENTS — Refer to instructions
below, Fig. 7-10, and Carrier Certified Prints for machine com-
ponent disassembly.
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 per-
sonal injury or damage to the unit.
CAUTION
Before rigging the compressor, disconnect all wires enter-
ing the power panel to avoid unit damage.
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: Weight for NIH 2-pass cover, 1034 kPa, is included in the
heat exchanger weights shown in Tables 6A and 6B.
NOTE: Wiring must also be disconnected. Label each wire
before removal (see Carrier Certified Prints). In order to dis-
connect the starter from the machine, remove wiring for the oil
pump, oil heater, control wiring at the power panel, 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.
To Separate Cooler and Condenser:
1. Place a support plate under each tube sheet to keep each
vessel level (Fig. 7, Item 6).
2. Cut the refrigerant motor cooling line at the location
shown (Fig. 7, Item 7).
3. Disconnect the compressor discharge elbow at the com-
pressor (Fig. 8, Item 6).
4. Cut the hot gas bypass line at the location shown (Fig. 7,
Item 1).
5. Unbolt the cooler liquid feed line at the location shown
(Fig. 7, Item 10).
6. Cover all openings.
7. Disconnect all wires and cables that cross from the cooler
side of the machine to the condenser side, including:
a. temperature sensor cable at the waterbox (Fig. 9,
Item 5)
