Location of Ice Machine
The location selected for the ice machine must meet the
following criteria. If any of these criteria are not met,
select another location.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 50°F (10°C), but
must not exceed 110°F (43°C).
• The water temperature must be at least 40°F (4°C),
but must not exceed 90°F (32°C).
• The location must not be near heat-generating
equipment or in direct sunlight.
• The location must be capable of supporting the
weight of the ice machine and a full bin of ice.
• The location must allow enough clearance for water,
drain and electrical connections in the rear of the ice
machine.
• The location must not obstruct airflow through or
around the ice machine.

Installation Requirements
• The ice machine and bin must be level.
• Vent the ice machine and bin drains separately.
• Bin drain termination must have an air gap.
• A backflow preventer is required on water inlet lines.
• The ice machine and bin must be sanitized after
installation.
• Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
• Routine adjustments and maintenance procedures

B.T.U./Hour
Because the heat of rejection varies during the ice making cycle
Ice machines, like other refrigeration equipment, reject
heat through the condenser. It is helpful to know the
amount of heat rejected by the ice machine when sizing
air conditioning equipment.
This information is also necessary when evaluating the
benefits of using water-cooled or remote condensers to
reduce air conditioning loads. The amount of heat added
to an air conditioned environment by an ice machine
using a water-cooled or remote condenser is negligible.
Knowing the amount of heat rejected is also important
when sizing a cooling tower for a water-cooled
condenser. Use the peak figure for sizing the cooling
tower.
