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.
MANITOWOC’S PATENTED CLEANING OR
SANITIZING TECHNOLOGY
Manitowoc Ice Machines include technology that allows
the initiation and completion of a cleaning or sanitizing
cycle at the flip of a switch. This cycle will permit
cleaning or sanitizing of all surfaces that come in contact
with the water distribution system. Periodic maintenance
must be performed that includes sanitizing the bin (or
dispenser) and adjacent surface areas, which cannot be
contacted by the water distribution system.
This technology will also allow initiation and completion
of a clean or sanitize cycle, after which the ice machine
automatically starts ice making again.
Refer to the cleaning or sanitizing procedure for
complete details.
The AuCS Accessory can be set to automatically start
and finish a clean or sanitize cycle every 2, 4, or 12
weeks. This accessory monitors ice-making cycles and
initiates a cleaning or sanitizing cycle automatically.
Refer to Automatic Cleaning System (AuCS) Accessory
for further details.
ALPHASAN
®
The goal of AlphaSan is to keep the plastic surfaces of
an ice machine cleaner, by reducing or delaying the
formation of bio-film. The active ingredient in AlphaSan
is the element silver in the form of silver ions (Ag+).
AlphaSan slowly releases silver ions via an ion
exchange mechanism. When AlphaSan is compounded
directly into a plastic part, a controlled release of silver
ions from the surface is regulated to maintain an
effective concentration at or near the surface of the
plastic ice machine part. AlphaSan’s unique ability to
effectively control the release of silver not only protects
against undesired discoloration of the plastic, but also
will last the life of the plastic part. Although AlphaSan
helps prevent bio-film build up it does not eliminate the
need for periodic cleaning and maintenance. AlphaSan
has no adverse effect on the taste of the ice or
beverage.
