It is recommended by the manufacturer that the following procedure be utilized to initially start-up and operate
the NAC-600 marine air conditioner:
Assure, by visual inspection, that the disconnect switch handle located in the lower front compartment
panel is in the "OFF" position. See Figure 4.
Upon completion of (1) above, the removal of the compressor compartment panel can now be
accomplished by the removal of two (2) screws which include washers.
Upon accomplishment of (2) above, the compressor which is color coded green includes a discharge and
suction valve integrally attached to the compressor, color coded by a bronze alloy color, located at the
bell of the compressor and between the cylinder heads of the compressor, requires back seating. The
stems of both valves should be turned counterclockwise until full back seating has been accomplished.
