CAUTION
1. 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.
2. 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.
• Water supply and drain connections must be installed in accordance with applicable
national, state, and local regulations.
• 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.

is recommended 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.
