) 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 to the entire male fitting, including threads, 

o-ring, and diaphragm, before making the connection. See Fig. 7.

Do not use thread sealant on the fittings. Use POE refrigerant oil 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. 8.

1) Route a 3/8" OD copper tube discharge line and a 1/4" OD copper tube liquid line 

between the remote condenser unit and the icemaker. Leave a service loop behind the 
icemaker to allow the icemaker to be pulled out for service. See Fig. 6.

1. Ensure that there are no traps and no kinks in the line set.
. Do not coil extra line set. Fabricate the line set to the proper length.

) Insulate the  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. 

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

refrigerant to the system (if using an electronic leak detector), and then raise the 
pressure using nitrogen gas (140 PSIG). 

5) Evacuate through the charging ports on the Parker quick connect couplings and charge 

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

6) 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 to the entire male fitting, including threads, 

o-ring, and diaphragm, before making the connection. See Fig. 7.

Do not use thread sealant on the fittings. Use POE refrigerant oil only.
