Potable Water Requirements
• Plumbing must conform to local codes.
• Water temperature: Minimum 37°F (3°C), Maximum
90°F (32°C).
• Do not connect the ice machine to a hot water supply.
Be sure all hot water restrictors installed for other
equipment are working. (Check valves on sink faucets,
dishwashers, etc.)
• If water pressure exceeds maximum pressure (80 psig
[552 kPa] obtain a water pressure regulator.
• A water shut-off valve is required to clean the ice
machine.
• A union for both the ice making and condenser water
lines is required.
• Water inlet lines require insulation to prevent
condensation.
• When local code requires, a back flow preventer must
be installed on the water inlet line.
Drain Connections
• Drain lines must have a 1.5 inch drop per 5 feet of run
(2.5 cm per meter), and must not create traps.
• The floor drain must be large enough to accommodate
drainage from all drains.
• Bin drain termination must have an air gap.
• Separate insulated bin and water-cooled condenser
drain lines are required.
• The bin and ice machine drains must be run separately.
