9. Cut the vaporizer refrigerant return line as shown (see
Fig. 17, item 13, or Fig. 18, item 8).
10. Disconnect all sensors with cables that cross from
the condenser side of the machine to the cooler side
including:
a. Evaporator refrigerant liquid temperature sensor.
b. Entering and leaving chiller liquid temperature
sensors. See Fig. 20.
c. Evaporator pressure sensor (not shown).
11. Disconnect the tubesheet mounting brackets from the
vessel connectors on the tube cooler tubesheet.
12. Cover all openings.
13. Rig the cooler away from the condenser/compressor.
NOTE: To reassemble, follow steps in reverse order. Connect
sensors and cables after major components have been secured
to reduce the risk of damaging them.
