6) Evacuate through the Schrader access ports on the Parker quick connect couplings and

charge with R-404A refrigerant vapor to a pressure of 15 to 30 PSIG.

7) Connect the refrigerant lines to the appropriate male ttings on the remote condenser

unit rst and then at the icemaker. Make a proper connection as follows:

a. Remove the protective covers from the male tting and female coupling.

b. Apply Polyol Ester (POE) refrigerant oil or Parker Super O Lube to the entire male

tting, including O-ring, diaphragm, and threads, before making the connection.

SeeFig. 13.

CAUTION

Do not use thread sealant on the ttings. Use POE refrigerant oil or Parker

Super O Lube only.

c. Make sure the male tting and female coupling are properly aligned, then start the

connection by hand to ensure that it is not cross threaded.

d. Tighten the connection with a wrench until it is tight. At this point, the nut has

covered most of the threads on the male tting.

e. Mark a reference line on the female coupling and the remote condenser unit or

icemaker panel. Using a backup wrench on the back of the female coupling, tighten

the six-sided nut of the female coupling an additional 1/6 turn. See Fig. 14.
