3)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. Go to step 2 in

"II.G.5.a) Factory Line Set Installation."

b)Field Fabricated Line Set Installation

1)Route the copper tube liquid line and copper tube discharge line (see "II.G.4 Line

Set Size and Refrigerant Charge" for details) from the remote condenser unit to the icemaker. Leave a service loop behind the icemaker to allow the icemaker to be pulled out for service. See Fig. 12.

NOTICE

Ensure that there are no traps and no kinks in the line set. The service loop is not considered an oil trap.

Do not coil extra line set. Fabricate the line set to the proper length.

2)Insulate the two copper tubes separately.

3)Install Parker quick connect couplings on each end. OS-QUICK, a universal quick connect coupling kit available as optional equipment from Hoshizaki America, is recommended. 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.

4)Allow the coupling to cool, then replace the Schrader valve core.

5)Use an electronic leak detector or soap bubbles to check for leaks. Add a trace

of refrigerant to the lines through the Schrader access ports on the Parker quick connect couplings (if using an electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG). WARNING! Do not use R-404A as a mixture with pressurized air for leak testing.

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 Oring, diaphragm, and threads, before making the connection.

See Fig. 13. NOTICE! 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 six-sided nut of the female coupling an additional 1/6 turn. See Fig. 14.

8)If the line set exceeds 66 feet, see "II.G.4. Line Set Size and Refrigerant Charge" for proper charging of the appliance.
