5. Line Set Installation
Precharged factory line sets, available as optional equipment from Hoshizaki America,
are recommended. For details, see "II.G.5.a) Factory Line Set Installation." Field
fabricated line sets are allowed. For details, see "II.G.5.b) Field Fabricated Line Set
Installation."
a) Factory Line Set Installation
1) Route the factory line set (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. 10. 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.5.a)(1) Factory Line Set Modication."
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.
2) Connect the refrigerant lines to the appropriate male ttings on the remote condenser
unit rst and then at the icemaker. 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.
SeeFig. 11. NOTICE! Do not use thread sealant on the ttings. Use POE
refrigerant oil or Parker Super O Lube 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 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. 12.
NOTICE! Conrm connection is free of leaks.
3) If you lengthened the line set as outlined in "II.G.5.a)(1) Factory Line Set Modication"
and it exceeds 66' (20 m), see "II.G.4. Line Set Size and Refrigerant Charge" for proper
charging of the appliance.
24
(1) Factory Line Set Modication
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.
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.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. 10.
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.
