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 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. 13.
CAUTION
Do not use thread sealant on the fittings. Use POE refrigerant oil or Parker Super O Lube 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. 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.
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
8)If the line set exceeds 66 feet, see "II.G.5 Refrigerant Charge (Line Set Exceeding 66 Feet)" for proper charging of the unit.
