Section 2 Installation
Part Number 000006505 Rev02 12/19 7
WATER SUPPLY AND DRAIN LINE SIZING/CONNECTIONS
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 rejection, 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°C).
• Water flow through the condenser must not exceed
5 gallons (19 liters) per minute.
• Allow for a pressure drop of 8 psi (1030 kPa)
between the condenser water inlet and the outlet of
the ice machine.
• Water exiting the condenser must not exceed 110°F
(43°C).
• Do not connect to the potable water filter system.
• Contact your distributor if your water pressure is
greater than 150 psig (1030 kPa). A special order
condensing unit is available that allows water
pressure up to 350 psig (2410 kPa).

Important
The Commonwealth of Massachusetts requires that
all water-cooled models must be connected only to a
closed loop, cooling tower system.
