WATER-COOLED CONDENSER
AND WATER REGULATING VALVE
Symptoms of restrictions in the condenser water circuit
include:
• Low ice production
• High water consumption
• High operating temperatures
• High operating pressures
If the ice machine is experiencing any of these symptoms,
the water-cooled condenser and water regulating valve
may require cleaning due to scale build-up.
The cleaning procedures require special pumps and
cleaning solutions. Follow the manufacturer’s
instructions for the specific cleaner being used.

Caution
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water
damage.
