3. Line Set Installation
Precharged factory line sets, available as optional equipment from Hoshizaki America,
are recommended. For installation details see "II.E.3.a) Factory Line Set Installation."
Field fabricated line sets are allowed. For installation details, see "II.E.3.b) Field
Fabricated Line Set Installation."
a) Factory Line Set Installation
1) Route the factory line set (see "II.E.2 Line Set Size and Refrigerant Charge" for
details) from the remote condensing unit to the icemaker. Leave a service loop behind
the icemaker to allow the icemaker to be pulled out for service. See Fig. 8. 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.E.3.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 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. 9. 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. 10.
(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) 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). Use an electronic leak detector or soap
bubbles to check for leaks. 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.3.a) Factory Line Set Installation."
24
b) Field Fabricated Line Set Installation
1) Route the copper tube liquid line and copper tube suction line (see "II.E.2 Line Set Size
and Refrigerant Charge" for details) from the remote condensing unit to the icemaker.
Leave a service loop behind the icemaker to allow the icemaker to be pulled out for
service. See Fig. 8.
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) 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). Use an electronic leak detector or soap
bubbles to check for leaks. 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. 9. 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. 10.

3. Infrared Sensor Shutdown Delay
This is the delay between the infrared sensor detecting ice and the start of the shutdown
sequence. The infrared sensor shutdown delay is factory-adjusted to 100 seconds and
no adjustment is required for most dispenser unit/ice storage bin applications.
a) Standard Ice Storage Bin
When installed on a standard ice storage bin, any shutdown delay setting is acceptable.
b) Dispenser Unit
For typical dispenser unit applications, a 100-second shutdown delay is recommended.
However, on some dispenser unit applications, the ice level at shutoff may need to be
adjusted depending on the dispenser agitation or dispense method. Should a different
shutdown delay be desired, adjust S1 dip switch 1, 2, 3 to obtain the shutdown delay
needed. See the table below. For further details, contact Hoshizaki Technical Support at
1-800-233-1940.
Note: When the shutdown sequence begins, the pump-down solenoid valve
de-energizes immediately to allow the low-side pressure to drop and open the
control low-pressure switch in the remote condensing unit. 5 minutes later the
gear motor de-energizes.
WARNING
Increasing the shutdown delay allows a higher level of ice in the dispenser unit/
ice storage bin before shutdown. This could lead to icemaker movement or ice
overow.
