Water Supply And Drain Connections - Hoshizaki KM-590DJE-R452 Bedienungsanleitung

G. Water Supply and Drain Connections
See Fig. 8.
WARNING
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
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
0.07MPa (0.7 bar) and a maximum of 0.78MPa
(7.8 bar). If the pressure exceeds 0.78MPa (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 0.07MPa (0.7 bar). Do not run the icemaker
until the proper water pressure is reached.
6. This icemaker will not work at sub-freezing
temperatures. To prevent damage to the water supply
line, drain the icemaker if the air temperature is going
to go below 0°C. For details, see "III. C. Preparing the
Icemaker for Long Storage."
• 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.
• The icemaker and condensation drain line(s), storage
bin drain line, and water-cooled condenser drain line (if
applicable) must be run separately. When stacking units,
each unit must have independent drain lines.
• Drain lines must have 2cm tall per 1 m on horizontal runs
to get a good flow. A vented tee connection is also required
for proper flow.
• Drain lines should not be piped directly to the sewer
system. An air gap of a minimum of 5 vertical centimeter
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.
1. Icemaker
• Icemaker water supply inlet is 1/2" female pipe thread
(FPT). A minimum of 3/8" (10mm) nominal copper water
tubing is recommended for the icemaker water supply line.
• An icemaker water supply line shut-off valve and drain
valve should be installed. A ball valve is recommended for
the shut-off valve. If another type of valve is used, it should
not have an opening smaller than the water supply line ID
as this can cause a reduced water flow rate which can lead
to poor harvest performance and/or freeze up.
• Icemaker drain outlet is 3/4" FPT. A minimum of
3/4" (18mm) nominal hard pipe is recommended for the
icemaker drain line. Condensation drain outlet is 3/8"
(9.5mm) OD hard tube. The condensation drain line can
be connected to the icemaker drain line or can be run
separately.
