4. Line Set
CAUTION
The icemaker, line set, and remote condenser unit must contain the same
type of refrigerant. Mixing of refrigerants will result in improper operation and
possible damage to the refrigeration system.
• Precharged factory line sets, available as optional equipment from Hoshizaki America, are
recommended. For details, see "II.G.4.a) Factory Line Set Installation." Field fabricated
line sets are allowed. For details, see "II.G.4.b) Field Fabricated Line Set Installation."
• The maximum line length for the standard refrigerant charge is 66 feet. With additional
refrigerant, the maximum line length is 100 feet. For details, see "II.G.5. Refrigerant
Charge (Line Set Exceeding 66 Feet)."
a) Factory Line Set Installation
1) Route the factory line set (5/8" OD discharge line and 3/8" OD liquid line) 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. 11. Factory fabricated line sets
are precharged and do not need to be evacuated. If the line set is too long or too short,
see "II.G.4.a)(1) Factory Line Set Modification."
CAUTION
1. Ensure that there are no traps and no kinks in the line set.
2. Do not coil extra line set.
2) 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. 12.
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 six-sided nut of the female coupling an additional 1/6 turn. See Fig. 13.
3) If you lengthened the line set as outlined in "II.G.4.a)(1) Factory Line Set Modification"
and it exceeds 66 feet, see "II.G.5 Refrigerant Charge (Line Set Exceeding 66 Feet)" for
proper charging of the unit.
(1) Factory Line Set Modification
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.
G.4.a) Factory Line Set Installation."
b) Field Fabricated Line Set Installation
1) Route a 5/8" OD copper tube discharge line and a 3/8" 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. 11.
CAUTION
1. Ensure that there are no traps and no kinks in the line set.
2. 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 (HS-2150), a universal
quick connect coupling kit available as optional equipment from Hoshizaki America, is
recommended. CAUTION! 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 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.
