personnel.
ꢀ. Failure to install the equipment within these guidelines may adversely affect
safety, performance, component life, and warranty coverage.
3. The icemaker, line set, and rack system must contain the same type of
refrigerant. Mixing of refrigerants will result in improper operation and
possible damage to the refrigeration system.
• The rack system must be sized to provide a maximum load of 5,700 BTU/h at 90°F (3ꢀ°C)
ambient temperature and 70°F (ꢀ1°C) water temperature.
• Install a p-trap in the suction line if required by the rack system's instructions.
• The evaporator pressure regulator (EPR) valve is factory adjusted to sustain a suction
pressure of 31 PSIG for a -ꢀ°F (-19°C) evaporator temperature. Adjust only if necessary.
• The icemaker is shipped with a holding charge of 3.5 oz. of R-404A.
• Charging port-equipped Parker quick connect couplings are needed to connect the line
set to the icemaker.
1. Line Set Installation
1) Route a 3/8" OD copper tube suction line and a 1/4" OD copper tube liquid line between
the icemaker and the rack system. Leave a service loop behind the icemaker to allow
the icemaker to be pulled out for service. See Fig. 11.
CAUTION
Do not coil extra line set. Fabricate the line set to the proper length.
ꢀ) Insulate the ꢀ copper tubes separately.
3) Braze the charging port-equipped Parker quick connect couplings to the icemaker end
of the copper tubes. Do not connect the charging port-equipped Parker quick connect
couplings to the icemaker at this time.
4) When using couplings to connect the line set to the rack system, braze them to the
rack system end of the copper tubes. Otherwise, braze the line set directly to the rack
system. Do not open the rack system service valves at this time.
5) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the line set copper tubes (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 the line set copper tubes 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.

7) Connect the refrigerant lines to the appropriate fittings on the rack system first (if not
already brazed on), then at the icemaker.
If the couplings to the rack system are not Parker quick connect couplings, follow the
coupling manufacturer's instructions. Make a proper Parker quick connect coupling
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. 1ꢀ.
CAUTION
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. 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 fitting. CAUTION! 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 unit 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.
8) Open the rack system service valves.

K. Bin Control Check
An infrared sensor is used as the primary bin control to control the level of ice in the
dispensing unit/storage bin. A mechanical bin control is used as a backup bin control.
IMPORTANT
1. Make sure the icemaker has been installed as outlined in this manual and
that the water supply is on.
ꢀ. Make sure S1 Dip Switch 7 is in the "ON" position. This allows the control
board to monitor the infrared sensor along with the mechanical backup bin
control.
1. Infrared Sensor Check
1) Turn off the power supply.
ꢀ) Remove the front panel, top panel, and control box cover.
3) Confirm that control board S1 dip switch 1, ꢀ, and 3 are in the proper position for your
application. "See IV.K.3. Infrared Sensor Shutdown Delay."
4) Move the control switch on the control box to the "ICE" position, then move the power
switch to the "ON" position.
5) Turn on the power supply to start the automatic icemaking process. The green LED on
the infrared sensor turns on. This LED confirms ꢀ0V DC power to the sensor.
6) Make sure the "GM" LED on the control board is on. See Fig. 17. There is a delay of
at least 30 seconds before the "GM" LED turns on after power-up. After the "GM" LED

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/storage bin applications.
a) Standard Storage Bin:
When installed on a standard 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, ꢀ, and 3 to obtain the shutdown
delay needed. See the table below. For further details, contact Hoshizaki Technical
Support at 1-800-ꢀ33-1940.
Note: When the shutdown sequence begins, the compressor de-energizes immediately
and then 5 minutes later the gear motor and fan motor de-energize.
WARNING
Increasing the shutdown delay allows a higher level of ice in the dispensing
unit/storage bin before shutdown. This could lead to icemaker movement or ice
overflow.
