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.
•  Self contained air cooled, water cooled or head section 
for remote air cooled condenser models - The air 
temperature must be at least 35°F (1.6°C), but must 
not exceed 110°F (43.4°C).
•  Remote air cooled condenser - The air temperature 
must be at least -20°F (-29°C), but must not exceed 
120°F (49°C).
•  Ice Making Water Inlet - Water Pressure must be 
at least 20 psi (1.4 bar), but must not exceed 80 psi 
(5.5 bar). 
•  Condenser Water Inlet - Water Pressure must be at 
least 20 psi (1.4 bar), but must not exceed 276 psi 
(19 bar).
•  The location must not be near heat-generating 
equipment or in direct sunlight and protected from 
weather.
•  The location must not obstruct air flow through or 
around the ice machine. Refer to chart below for 
clearance requirements.
•  The ice machine must be protected if it will be 
subjected to temperatures below 32°F (0°C). Failure 
caused by exposure to freezing temperatures is not 
covered by the warranty. See “Removal from Service/
Winterization”.
