F. Water Supply and Drain Connections
See Fig. 4.
WARNING
1. Water supply and drain connections must be installed in accordance with
applicable national, state, and local codes and regulations.
2. 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.
3. 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 should 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 storage bin drain line and drip tray 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 storage bin
and drip tray and the oor drain.
