Section 2 Installation
Air Gap
A greater than 1-inch air gap is built into
the ice machine for back-flow prevention.
This air gap exceeds NSF 12 requirements
for back-flow prevention.
Cooling Tower Applications
(Water-Cooled Models)
A water cooling tower installation does not
require modification of the ice machine.
• Water pressure at the condenser cannot
exceed 150 psig (1034 kPa). A special
order unit is available that allows water
pressure up to 350 psig (2413 kPa).
• Water entering the condenser must not
exceed 90°F (32°C).
• Water flow through the condenser
must not exceed 5 gallons (19 liters) per
minute.
• Allow for a pressure drop of 7 psi
(50 kPa) between the condenser water
inlet and the outlet of the ice machine.
• Water exiting the condenser must not
exceed 110°F (43°C).
Drain Connections
Follow these guidelines when installing
drain lines to prevent drain water from
flowing back into the ice machine and
storage bin:
• Drain lines must have a of run 1.5 inch
drop per 5 feet (2.5 cm per meter) and
must not create traps.
• The floor drain must be large enough to
accommodate drainage from all drains.
• Run separate bin and ice machine
drain lines. Insulate them to prevent
condensation.
• Vent the ice machine drain to the
atmosphere.
• Drain termination must have an air gap
that meets local code.
Auxiliary Base Drain Installation
An auxiliary drain is located in the ice
machine base to remove moisture in high
humidity areas.
1. View the back of the ice machine base
on the compressor side and locate and
remove the cap plug.
2. Route tubing to an open site drain:
• Use 1/2 inch CPVC tubing.
• Apply a bead of silicone around the
exterior of the ice machine tubing
and insert into ice machine base. The
silicone will secure the tubing and
provide a watertight seal.
• Provide support for tubing.
This air gap is greater than 1"
