3. Line Set Installation

WARNING

• R-404A itself is not ammable at atmospheric pressure and temperatures up to
176°F (80°C).

• R-404A itself is not explosive or poisonous. However, when exposed to high
temperatures (open ames), R-404A can be decomposed to form hydrouoric
acid and carbonyl uoride both of which are hazardous.

• Do not use silver alloy or copper alloy containing arsenic.

• Do not open any shut off valve until the line set installation is complete and leak
tested.

• Ensure that there are no unnecessary traps and no kinks in the line set.

• Do not coil extra line set.

• Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the line set tubing through the shut off valve access ports (if using
an electronic leak detector), and then raise the pressure using nitrogen gas (140
PSIG). Do not use R-404A as a mixture with pressurized air for leak testing.

1) Route the factory line set or appropriate size copper tubing. When eld fabricating,
insulate the copper tubes separately. Leave a service loop behind the icemaker to
allow the icemaker to be pulled out for service. See Fig. 8. Note: The service loop is not
considered an oil trap.

2) Remove any extra line set length.

3) NOTICE! Before brazing, remove the Schrader valve cores from the liquid line

and suction line shut off valve access ports. When brazing, protect the valves by
using a wet cloth to prevent the valves from overheating.

4) Braze the line set to the icemaker liquid line and suction line shut off valves rst, then to
the remote condensing unit liquid line and suction line shut off valves.

5) Allow the liquid line and suction line shut off valves to cool, then replace the Schrader
valve cores.

6) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the line set tubing through the shut off valve access ports (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.

7) Attach the gauge manifold hoses to the liquid line and suction line shut off valve access
ports and evacuate the line set tubing. Allow the vacuum pump to pull down to a 29.9"
Hg vacuum. Evacuating period depends on pump capacity. Next, charge each line set
tube with R-404A vapor to a pressure of 15 to 30 PSIG.

8) Close both gauge manifold valves.

9) Disconnect the gauge manifold hoses.

10) Replace the access port caps and tighten.

11) Open the icemaker liquid line and suction line shut off valves rst, then open the remote
condensing unit liquid line, suction line, and discharge line shut off valves.

21

12) Replace the valve caps and tighten.

13) Insulate all exposed tubing and ttings.

2. 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
overow.
