Perlick H50IMS-ADL User Manual

21

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 Perlick distributor for recommendations. 

• Water supply inlet is 1/2" female pipe thread (FPT).
• 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 line. 

• 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.
• 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 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.
