Water Supply And Drain Connections - Hoshizaki KML-351MAH Instruction Manual

F. Water Supply and Drain Connections
See Fig. 4
Do not operate the icemaker when the water supply is OFF, or if the pressure
is below 10 PSIG (0.7 bar). Do not run the icemaker until the proper water
pressure is reached.
• Water supply inlet is 1/" female pipe thread (FPT).
Note: On water-cooled model, two water supply inlets are provided. One is the water
supply inlet for icemaking, and the other (1/" FPT) is for the water cooled
condenser.
• A water supply line shut-off valve and drain valve must be installed. A minimum of 3/8" OD
copper tubing is recommended for the water supply lines.
• Water supply pressure should be a minimum of 10 PSIG (0.7 bar) and a maximum of
113 PSIG (7.5 bar). If the pressure exceeds 113 PSIG (7.5 bar), the use of a pressure
reducing valve is required.
• Drain outlet for icemaker dump is 3/4" FPT. The icemaker drain must be made separately
from the bin drain.
Note: On water-cooled model, a 3/8" FPT is provided for the condenser drain outlet.
• The drains must have 1/4" fall per foot ( 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
 vertical inches (5 cm) should be between the end of the drain pipes from the icemaker,
icebin and water-cooled condenser (if applicable) and the floor drain.
• This icemaker should 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.
• In some areas, a back flow preventer may be required in the cooling water circuit.
