Refrigeration Line Set Installation
GENERAL
Refrigeration line set installations consist 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 Verify Ice Machine and CVD Condensing
Unit Locations Are Within Guidelines.
Prior to installation of the ice machine head section and
CVD condensing unit be sure that the distance between
then is within the line set routing guidelines outlined in
this manual.
Roof/Wall Penetration
If required, cut a 3-inch (76.2 mm) circular hole in the
wall or roof for routing of refrigeration tubing. A qualified
person must perform all roof penetrations.
Step 2 Route Refrigeration Tubing
Properly route refrigeration tubing between the ice
machine head section and the CVD condensing unit.
A. LINE SET LENGTH
100 feet (30.5 m) Length: The maximum measured
length the line set can be.
B. LINE SET RISE OR DROP
35 feet (10.7 m) Rise: The maximum distance the CVD
condensing unit can be above the ice machine.
15 feet (4.5 m) Drop: The maximum distance the CVD
condensing unit can be below the ice machine.

The following instructions are provided as a general
overview of a typical QuietQube® installation. Refer
to the Installation, Use and Care Manual for each
specific model for step by step installation
instructions.
Important
QuietQube® ice machines will not function with line
sets greater than 100 feet (30.5 m). Do not attempt to
go beyond this distance and add refrigerant charge to
compensate!
