DRAIN CONNECTIONS
Follow these guidelines when installing drain lines
to prevent drain water from flowing back into the ice
machine and storage bin:
• 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.
• Install a tee to vent the ice machine drain to the
atmosphere.
• Insulate drain lines to prevent condensation.
COOLING TOWER APPLICATIONS
Water Cooled Models Only
A water-cooling tower installation does not require
modification of the ice machine. The water regulator
valve for the condenser continues to control the
refrigeration discharge pressure.
It is necessary to know the amount of heat rejected, and
the pressure drop through the condenser and water
valves (inlet to outlet) when using a cooling tower on an
ice machine.
• Water entering the condenser must not exceed 90°F
(32.2°C).
• Water flow through the condenser must not exceed 5
gallons (19 liters) per minute.
• Allow for a pressure drop of 7 psig (.48 bar) between
the condenser water inlet and the outlet of the ice
machine.
• Water exiting the condenser must not exceed 110°F
(43.3°C).
Caution
Plumbing must conform to state and local codes.
