Water Supply and Drain Line Sizing/Connections

,
Do not apply heat to water inlet valve or water drain
fittings. Heating will damage the nonmetallic connector.
Do not over tighten fittings. Two turns after hand tight is
the maximum.

I0906 Marine Space Saver Models
This model allows water and electrical connections on the
top of the ice machine. The drain exits on the right side of
the ice machine.

Air Gap
A greater than 1-inch air gap is built into the ice machine
for back-flow prevention. This air gap exceeds NSF 12
requirements for back-flow prevention.

• Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
• Connect ice making water inlet to potable water only.
• Do not connect to hot water supply.
• Install a water shut-off valve.
• Insulate water and drain lines to prevent condensation.

Cooling Tower Applications (Water-Cooled
Models)
A water cooling tower installation does not require
modification of the ice machine.
• Water pressure at the condenser cannot exceed 1034 kPa
(150 psig). A special order unit is available that allows
water pressure up to 2413 kPa (350 psig).
• Water entering the condenser must not exceed 32°C
(90°F).
• Water flow through the condenser must not exceed
Drain
19 liters (5 gallons) per minute.
• Allow for a pressure drop of 50 kPa (7 psi) between the
condenser water inlet and the outlet of the ice machine.
• Water exiting the condenser must not exceed 43°C
(110°F).
