See Fig. 4, 5, and 6
WARNING
Water supply and drain connections must be installed in accordance with applicable
national, state, and local regulations.
NOTICE
• Normal operating water temperature must be within 45°F to 90°F (7°C to
32°C). Operation of the appliance, for extended periods, outside of this normal
temperature range may affect appliance performance.
• 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.
• External filters, strainers, or softeners may be required depending on water quality.
Contact your local Hoshizaki Certified Service Representative or local Hoshizaki
distributor for recommendations.
• A plumbing permit and services of a licensed plumber may be required in some areas.
• The icemaker drain line, dispenser unit/ice storage bin drain line, and water-cooled
condenser drain line (if applicable) 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
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
2 vertical inches (5-cm) must be between the end of the drain pipes from the icemaker,
dispenser unit/ice storage bin, and water-cooled condenser (if applicable) and the floor
drain.
