7) Connect the refrigerant lines to the appropriate male fittings on the remote condenser
unit first and then at the icemaker. Make a proper connection as follows:
a. Remove the protective covers from the male fitting and female coupling.
b. Apply Polyol Ester (POE) refrigerant oil or Parker Super O Lube to the entire male
fitting, including O-ring, diaphragm, and threads, before making the connection.
See Fig. 11. NOTICE! Do not use thread sealant on the fittings. Use POE
refrigerant oil or Parker Super O Lube only. Couplings are one-time use only.
c. Make sure the male fitting and female coupling are properly aligned, then start the
connection by hand to ensure that it is not cross threaded.
d. Place a backup wrench on the back of the female coupling, then tighten the
connection with a wrench until it is tight. At this point, the nut has covered most of
the threads on the male fitting. NOTICE! Failure to use a backup wrench may
result in damage to the line set and possible refrigerant leaks.
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. 12.
NOTICE! Confirm connection is free of leaks.
8) If the line set exceeds 66' (20 m), see "II.G.4. Line Set Size and Refrigerant Charge" for
proper charging of the appliance.
