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.

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.

Line Set Length
The maximum length is 100' (30 m).
The ice machine compressor must have the
proper oil return. The receiver is designed
to hold a charge sufficient to operate the
ice machine in ambient temperatures
between -20°F (-29°C) and 120°F (49°C),
with line set lengths of up to 100' (30 m).
Line Set Rise/Drop
The maximum rise is 35' (10.7 m).
The maximum drop is 15' (4.5 m).



otice
If a line set has a rise followed by a drop,
another rise cannot be made. Likewise,
if a line set has a drop followed by a rise,
another drop cannot be made.
Calculated Line Set Distance
The maximum calculated distance is 150'
(45 m).
Line set rises, drops, horizontal runs (or
combinations of these) in excess of the
stated maximums will exceed compressor
start-up and design limits. This will cause
poor oil return to the compressor.
