Water Supply And Drain Connections - Hoshizaki DCM-270BAH-OS Instruction Manual

F. Water Supply and Drain Connections
See Fig. 3
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 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 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 3/8" OD copper tubing
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.
• Drain outlet is 3/4" MPT. A minimum of 3/4" OD hard pipe is recommended for the drain
line.
• Drain lines 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.
• 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.
