G. Water Supply and Drain Connections
See Fig. 12
WARNING
Water supply and drain connections must be installed in accordance with applicable
national, state, and local regulations.
NOTICE
• 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 performance.
• To prevent damage to equipment, do not operate the icemaker when the water
supply is off, or if the pressure is below 10 PSIG. 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 lters, strainers, or softeners may be required depending on water quality. Contact
your local Hoshizaki distributor for recommendations.
• Water supply pressure must be a minimum of 10 PSIG and a maximum of 113 PSIG. If the
pressure exceeds 113 PSIG, the use of a pressure reducing valve is required.
• The icemaker drain line and dispenser unit/ice storage bin drain line must be run
separately.
• Drain lines must have 1/4" fall per foot (2 cm per 1 m) on horizontal runs to get a good
ow. A vented tee connection is also required for proper ow.
• 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 dispenser unit/ice storage bin and the oor drain.
