Ice Machine Clearance Requirements
All Models Clearance Requirements
Back 5” (12.7 cm)
Sides/Top 8” (20.3 cm)
RCUF Units Remote Condensing Unit
Front/Back 24” (61.0 cm)
Sides/Top 6” (15.2 cm)
24 inches clearance on top
and sides is recommended for
serviceability
NOTE: Allowance must be made for removal when the ice
machine is built-in. Removal of the top panel is required
for cleaning and sanitizing.
Cooling Tower Applications
A water cooling tower installation does not require
modification of the ice machine. The water regulator valve
for the condenser continues to control the refrigeration
discharge pressure.
It is necessary to know the amount of heat rejection, and
pressure drop through the condenser and water valves
(inlet and outlet) when using a cooling tower on an ice
machine.
• Water entering the condenser must not be lower than
37°F (3°C) or exceed 90°F (32°C).
• Water flow through the condenser must not exceed 5
gal. (19 L) per minute.
• Allow for a pressure drop of 7 psi (48 kPa) between
the condenser water inlet and the outlet of the ice
machine.
• Water exiting the condenser must not exceed 110°F
(43°C).
• Water entering the condenser must not exceed 84 psi
(6 bar).
