• Do not coil extra line set.

2) Connect the refrigerant lines to the appropriate male ttings on the icemaker rst and
then at the remote condensing unit. Make a proper 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.
See Fig. 15.

NOTICE

Do not use thread sealant on the ttings. Use POE refrigerant oil or Parker Super O
Lube 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. 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.

e. Mark a reference line on the female coupling and the remote condensing 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. 16.

(1) Factory Line Set Modication

1) Recover the line set charge through the Schrader access ports on the Parker quick
connect couplings and store it in an approved container. Do not discharge the
refrigerant into the atmosphere. Remove the extra line set length or add extra tubing.
When adding extra tubing, insulate the additional copper tubes separately. Braze the
connections.

2) 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.

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.E.2.a) Factory Line Set Installation."

23

b) Field Fabricated Line Set Installation

1) Route a 5/8" OD copper tube suction line and a 1/2" OD copper tube liquid line

between the remote condensing unit and the icemaker. Leave a service loop behind the
icemaker to allow the icemaker to be pulled out for service. See Fig. 14.

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.

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 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 ttings on the icemaker rst and
then at the remote condensing unit. Make a proper 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.
See Fig. 15.

NOTICE

Do not use thread sealant on the ttings. Use POE refrigerant oil or Parker Super O
Lube 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. 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.

e. Mark a reference line on the female coupling and the remote condensing 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. 16.
