Water Supply And Drain Connections - Hoshizaki KML-350MAH Instruction Manual

6. 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. Do not run the icemaker until the proper water pressure
is reached.
• Water supply inlet is 1/2" female pipe thread (FPT).
Note: On water-cooled model, two water supply inlets are provided. One is for the ice
making water inlet, and the other is for the cooling water inlet.
• A water supply line shut-off valve and drain valve should be installed. A minimum of
3/8" OD copper tubing is recommended for the water supply lines.
Note: An optional strainer should be installed next to the water supply inlet in the water
supply line. HOSHIZAKI recommended optional strainer Part Code 311166A01.
• 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 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 on horizontal runs to get a good flow.
• The drains should not be piped directly to the sewer system. An air gap of a minimum of
2 vertical inches should be between the end of the drain pipe from the icemaker or the ice
bin 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.
