3) Install Parker quick connect couplings on the icemaker end of the line set. OS-QUICK,
a universal quick connect coupling kit, is required. NOTICE! Before brazing, remove
the Schrader valve core from the access port. When brazing, protect the coupling
by using a wet cloth to prevent the coupling from overheating. Do not use silver
alloy or copper alloy containing arsenic. Braze all ttings while purging with
nitrogen gas owing at a pressure of 3 to 4 PSIG.
4) Allow the Parker quick connect couplings to cool, then connect the couplings to the
icemaker (a small amount of nitrogen is released from the icemaker at this time). Do not
replace the Schrader valve cores at this time.
Make a proper Parker quick connect coupling 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.
SeeFig. 16. NOTICE! Do not use thread sealant on the ttings. Use POE
refrigerant oil or Parker SuperOLube only. Couplings are one-time use 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. 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 tting. 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 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. 17.
5) Replace the Parker quick connect coupling Schrader valve cores.
6) Connect the rack system end of the line set per the rack system instructions. NOTICE!
Do not open the rack system service valves at this time.
7) Use an electronic leak detector or soap bubbles to check for line set connection leaks.
Place refrigerant gauges on the line set Parker quick connect coupling Schrader access
ports, then add a trace of refrigerant to the line set (if using an electronic leak detector),
and then raise the pressure using nitrogen gas (140 PSIG). WARNING! Do not use
refrigerant as a mixture with pressurized air for leak testing. NOTICE! Conrm
connections are free of leaks.
8) After checking the line set for leaks, move the refrigerant gauges to the Schrader access
ports inside the icemaker. Vent the icemaker nitrogen holding charge. After venting the
nitrogen, evacuate the icemaker and line set.
9) After evacuation, charge the icemaker and line set with refrigerant vapor (R-404A,
R-407A, or R-407F) to a pressure of 15to 30 PSIG.
10) Open the rack system service valves.
