securely in place after installation. Make sure that no
components, fasteners, or thumbscrews have fallen
into the storage bin.
A. Location
CAUTION
1. This icemaker is not intended for outdoor use.
Normal operating ambient temperature should
be within 45°F to 100°F (7°C to 38°C); Normal
operating water temperature should be within
45°F to 90°F (7°C to 32°C). Operation of the
icemaker, for extended periods, outside of these
normal temperature ranges may affect icemaker
performance.
2. This icemaker will not work at sub‑freezing
temperatures. To prevent damage to the water
supply line, have a qualified service technician
drain the icemaker if the air temperature is going to
go below 32°F (0°C). Instructions for draining the
icemaker are provided in the Installation Manual
supplied with this icemaker under "Preparing the
Icemaker for Long Storage."
3. Do not place anything in front of the louver(s)
(air‑cooled models).
B. Electrical Connection
WARNING
1. Electrical connection must meet national, state, and
local electrical code requirements. Failure to meet
these code requirements could result in death,
electric shock, serious injury, fire, or severe damage
to equipment.
2. This unit requires an independent power supply of
proper capacity. See the nameplate for electrical
specifications. Failure to use a properly sized
breaker or fuse can result in a tripped breaker,
blown fuses, or damage to existing wiring. This
could lead to heat generation or fire.
3. THIS UNIT MUST BE GROUNDED (EARTHED).
Failure to properly ground (earth) this unit could
result in death or serious injury.
4. ON REMOTE AIR-COOLED MODEL, THE
REMOTE CONDENSER UNIT MUST ALSO BE
GROUNDED (EARTHED). The power supply and
ground (earth) wire to the remote condenser unit are
supplied from the icemaker.
• Usually an electrical permit and services of a licensed
electrician are required.
• If a power cord and/or a plug should need to be fitted/
replaced, it should only be done by a qualified service
technician.
• Factory fitted power cords are coloured in accordance with
the following code:
Green and Yellow = Ground (Earth)
Blue = Neutral
Brown = Line
Note: Plugs and power cords are not supplied with
KM‑1301S_J‑E.
C. Water Supply and Drain Connections
1. Water supply and drain connections must be
installed in accordance with applicable national,
state, and local regulations.
2. The icemaker water supply must be potable water.
3. Normal operating water temperature should be
within 45°F to 90°F (7°C to 32°C). Operation of
the icemaker, for extended periods, outside of this
normal temperature range may affect icemaker
performance.
4. Water supply pressure should be a minimum of
10 PSIG (0.7 bar) and a maximum of 113 PSIG
(7.8 bar). If the pressure exceeds 113 PSIG (7.8 bar),
the use of a pressure reducing valve is required.
DO NOT throttle back the supply tap.
5. To prevent damage to equipment, do not operate
the icemaker when the water supply is off, or if the
pressure is below 10 PSIG (0.7 bar). Do not run the
icemaker until the proper water pressure is reached.
• A plumbing permit and services of a licensed plumber may
be required in some areas.
• External filters, strainers, or softeners may be required
depending on water quality. Contact your local Hoshizaki
distributor for recommendations.
• Drain lines should not be piped directly to the sewer
system. An air gap of a minimum of 2 vertical inches
(5 cm) should be between the end of the drain pipes from
the icemaker and condensation drain, storage bin, and
water‑cooled condenser (if applicable) and the floor drain.
