F. Water Supply and Drain Connections
WARNING
1. Water supply and drain connections must be installed in accordance with
applicable national, state, and local regulations.
2. Normal operating water temperature should be within 45°F to 95°F (7°C
to 35°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 filters, strainers, or softeners may be required depending on water quality.
Contact your local Hoshizaki distributor for recommendations.
• Water supply inlet is 1/2" female pipe thread (FPT). A minimum of 1/4" nominal ID
copper water tubing or equivalent is required for the water supply line.
• A water supply line shut-off valve and drain valve should be installed.
• 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.
• Drain outlet is 1/2" FPT. A minimum of 1/2" nominal ID hard pipe or equivalent is
required for the drain line.
• Drain line 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 pipe from the icemaker
and the floor drain.
• For gravity drain installation, drain line must have 1/4" fall per foot (2 cm per 1 m) on
horizontal runs to get good flow. A vented tee connection is also required for proper
flow.
• For optional drain pump installation, refer to the instruction manual included with the
pump.
