Refrigeration Line Set Installation - Manitowoc QR0670C Technician Manual

Potential Personal Injury Situation
The ice machine head section contains the
refrigerant charge. Installation and brazing of the line
sets must be performed by a properly trained
refrigeration technician aware of the dangers of
dealing with refrigerant charged equipment.

Refrigeration Line Set Installation

Refrigeration line set installation consists of vertical
and horizontal line set distances between the ice
machine and the condensing unit. The following
guidelines, drawings and calculation methods must be
followed to assure proper oil return and CVD
Condensing Unit/ice Machine operation.
Step 1. Prior to installation of the ice machine and
®
CVD Condensing Unit be sure that the distance
between them is within the line set routing guidelines
outlined in this manual.
Step 2. Properly route refrigeration tubing between the
Ice Machine Head Section and the CVD
Unit.
For a roof/wall penetration, cut a 3-in. (76.2 mm)
circular hole in the wall or roof for routing of
refrigeration tubing, as required. A qualified person
must perform all roof penetrations.
