NOTE: Weight for NIH 2-Pass Cover, 150 psig is included in the heat exchanger weights shown in Table 6.
NOTE: If the cooler and condenser vessels must be sepa-
rated, 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 ves-
sels are bolted back together.
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. 6, Item 6).
2. Cut the refrigerant motor cooling line at the location shown
(Fig. 6, Item 7).
