WATER

The quality of the water supplied to the ice
machine will have an impact on the time between
cleanings and ultimately on the life of the product.
There are two ways water can contain impurities:
in suspension or in solution. Suspended solids
can be filtered out. In solution or dissolved
solids cannot be filtered, they must be diluted or
treated. Water filters are recommended to
remove suspended solids. Some filters have
treatment in them for suspended solids. Check
with a water treatment service for a
recommendation.
RO water. This machine can be supplied with
Reverse Osmosis water, but the water
conductivity must be no less than 10
microSiemens/cm.
Potential for Airborne Contamination
Installing an ice machine near a source of yeast
or similar material can result in the need for
more frequent sanitation cleanings due to the
tendency of these materials to contaminate the
machine. Most water filters remove chlorine
from the water supply to the machine which
contributes to this situation. Testing has shown
that using a filter that does not remove chlorine
will greatly improve this situation, while the ice
making process itself will remove the chlorine
from the ice, resulting in no taste or odor impact.
Additionally, devices intended to enhance ice
machine sanitation can be placed in the machine
to keep it cleaner between manual cleanings.
Water Purge
Cube ice machines use more water than what
ends up in the bin as ice. While most water is
used during ice making, a portion is designed to
be drained out every cycle to reduce the amount
of hard water scale in the machine. That's
known as water purge, and an effective purge
can increase the time between needed water
system cleaning.
In addition, this product has the capability to
automatically vary the amount of water purgeed
based on the purity of the water supplied to it.
The water purge rate can also be set manually.
Adjustments of purge due to local water
conditions are not covered by warranty.
GENERAL INSTALLATION
Air or Water Cooled
Location Limitations:
The product is designed to be installed indoors,
in a controlled environment. Air cooled models
discharge very warm air into the room out the
back. Space must be allowed at the left side and
back for air intake and discharge. Water cooled
models discharge warm water into the building's
drain. Space needs to be provided on both
sides and above for service access.
Space Limitations
Note: Although the machine will function, ice
capacity of air cooled machines will be
significantly reduced with minimal clearance
at the sides, back and top. Some space is
recommended for service and maintenance
purposes on all models.
15 cm (6") of space at the sides and back are
required for adequate operation. To get the most
capacity, locate the machine away from heat
producing appliances and heating ducts.
Airflow is in the left side, out the back (as viewed
from the front).
Environmental Limitations
Minimum
Air temperature 10°C (50F)
Water temperature 5°C (40F)
Water pressure 1 bar (14 psi)
Power supply - acceptable voltage ranges

Warranty Information
The warranty statement for this product is provided
separately from this manual. Refer to it for
applicable coverage. In general warranty covers
defects in material or workmanship. It does not
cover maintenance, corrections to installations,
or situations when the machine is operated in
circumstances that exceed the limitations printed
above.
Plumbing Requirements
All models require connection to cold, potable
water. A hand actuated valve within site of the
machine is required. Air cooled models have a
single 3/4" male inlet water connection.
Water cooled models have the same inlet fitting
plus an additional 3/4" male condenser inlet
water connection.
