Installation Instructions

GENERAL

Condensers must be mounted horizontally with the fan
motor on top with nothing obstructing it. There must be at
least a 16" (41 cm) clearance from the bottom for air intake.
The front coupling panel and one other panel (back or side)
must also be unobstructed.
Remote condenser installations consist of vertical and
horizontal line sets between the ice machine and the
condenser. When combined, they must fit within approved
specifications. The following guidelines, drawings and
calculation methods must be followed to verify a proper
remote condenser installation.
! Caution
The compressor warranty (including the labor
replacement warranty) will not apply if the remote ice
machine is not installed according to specifications.
The warranty also will not apply if the refrigeration
system is modified with a condenser, heat reclaim
device, or other parts or assemblies not manufactured
by us unless we specifically approved the component in
writing.

WIRING

Interconnecting line voltage wiring is used to energize and
de-energize the condenser fan motor.
• The remote condenser voltage matches the ice machine
head section voltage.

GUIDELINES FOR ROUTING LINE SETS

First, cut a 2.5" (6.35 cm) circular hole in the wall or roof for
tubing routing. The line set end with the 90° bend will
connect to the ice machine. The straight end will connect to
the remote condenser.
Follow these guidelines when routing the refrigerant lines.
This will help ensure proper performance and service
accessibility.
1. Optional - Make the service loop in the line sets (as
shown in Routing Line Sets graphic). This permits easy
access to the ice machine for cleaning and service. Do
not use hard rigid copper at this location.
2. Required - Do not form traps in the refrigeration lines
(except the service loop). Refrigerant oil must be free to
drain toward the ice machine or the condenser. Route
excess tubing in a supported downward horizontal
spiral (as shown below). Do not coil tubing vertically.
3. Required - Keep outdoor refrigerant line runs as short as
possible.
