13. Cut and discard the wire ties used to hold the base plate to the compressor.
14. Place the new SST washers on each side of the resilient mounts, and the new Mylar washer on the bottom
of it as shown in Figure 7.5 . Install the four base mounting bolts loosely.
15. Place the new Teflon seals at the compressor suction and discharge ports as well as the O-rings at the
unloader and economizer line connection ports. Hand tighten all four connections.
16. Torque the four base-mounting screws to 6.2 mkg (45 ft-lbs).
17. Torque the compressor ports / connections.
18. Connect (butt-splice and heat shrink) the new compressor dome temperature sensor with the old sensor
wires removed in step 8. Wire-tie any loose wiring as appropriate.
19. Evacuate the compressor to 1000 microns if the unit was pumped down before the replaced compressor
was removed. Otherwise, evacuate the complete unit and charge it with refrigerant (see Section 7.6.1 and
