Installation Instructions

 

 

GENERAL

Condensers must be mounted horizontally with the fan motor on top.

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 60 month compressor warranty (including the 36 month labor replacement warranty) will not apply if the remote ice machine is not installed according to specifications.

This 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 Manitowoc Ice, Inc., unless specifically approved in writing by Manitowoc Ice, Inc.

GUIDELINES FOR ROUTING LINE SETS

First, cut a 2.5" (63.5 mm) 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 insure proper performance and service accessibility.

1.Optional - Make the service loop in the line sets (See below). 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 (See below). Do not coil tubing vertically.

3.Required - Keep outdoor refrigerant line runs as short as possible.
