Section 2
Water Connections
• Local water conditions may require
treatment of the water to inhibit scale
formation, filter sediment, and remove
chlorine odor and taste.
• Follow these guidelines to install water
inlet lines:
• Plumbing must conform to local codes.
• 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.)
• ST3000W ‑ are equipped with a High
Pressure Valve rated for water pressure
from 20 psi to 350 psi (1.37 bar to
24.1 bar).
• SF3000C ‑ If water pressure exceeds
the maximum recommended pressure
of 80 psig (1.5 bar), obtain a water
pressure regulator from your Manitowoc
distributor.
• Install a water shut‑off valve and union
for potable water and water cooled
condenser lines.
• Insulate water inlet lines to prevent
condensation.
,
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.

Connect to a potable water supply only

Caution
Warning
Water-Cooled Condenser Water Pressure
ST300W ‑ Water pressure at the condenser
cannot exceed 350 psi (24.1 bar).
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.
• 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
(0.5 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).

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