Remote Condensing Unit - Hoshizaki Serenity Series KMS-1401MLJ Instruction Manual

2. Remote Condensing Unit

The remote condensing unit is intended for outdoor use. Normal operating ambient
temperature must be within -20°F to 122°F (-29°C to 50°C). Operation of the
remote condensing unit, for extended periods, outside of this normal temperature
range may affect icemaker performance.
The icemaker must be coupled with the appropriate remote condensing unit as listed
below.
Failure to install the equipment within these guidelines may adversely affect
performance, component life, and warranty coverage.
The remote condensing unit must be positioned in a permanent site under the following
guidelines:
• A firm and flat site.
• A dry and well ventilated area with 24" (61 cm)
clearance in both front and rear for proper air circulation
and ease of maintenance and/or service should they be
required. See Fig. 1.
• The maximum line set length is 66 feet.
• The maximum vertical distance between the remote condensing unit and icemaker is
33 feet above or 10 feet below the icemaker. These distances are measured fitting to fitting.
See Fig. 2.
• If the vertical distance between the remote condensing unit and the icemaker is greater
than 20 feet (not to exceed 33 feet), an "S" oil-trap (5/8" OD copper tubing) must be
installed in the suction line. The "S" oil-trap must be located halfway between the icemaker
and remote condensing unit. This ensures sufficient oil return to the compressor.
