Installation Instructions Section 2
Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment,
remove chlorine, and improve taste and clarity.
Important
If you are installing a Manitowoc Tri-Liminator
water filter system, refer to the Installation
Instructions supplied with the filter system for ice
making water inlet connections.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
• 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 the maximum (80 psig-
551.5 kPA) recommended pressure, obtain a
water pressure regulator from your Manitowoc
distributor.
• Install a water shut-off valve and union for both
the ice making and condenser water lines.
• Insulate water inlet lines to prevent condensation.
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 (3.8 cm)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.
• Run separate bin and water-cooled condenser
drain lines. Insulate them to prevent condensation.
• Vent the bin drain to the atmosphere. Do not vent
the condenser drain on water-cooled models.
COOLING TOWER APPLICATIONS
(Water-Cooled Models)
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 rejection,
(refer to page 2-3) and the pressure drop through the
condenser and water valves (inlet and 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 psi (48 kPA)
between the condenser water inlet and the outlet
of the ice machine.
• Water exiting the condenser must not exceed
110°F (43.3°C).
Important
The Commonwealth of Massachusetts requires that
all water-cooled models must be connected only to
a closed loop, cooling tower system.
