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.
