Section 2
Refrigeration Line Set Installation
Remote Condensing Unit Only
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 remote condensing unit/ice
machine operation.
The refrigeration line set installer must be USA
Government-Environmental Protection Agency (EPA)
certified in proper refrigerant handling and servicing
procedures.
The ice machine head section contains refrigerant
charge. The ice machine head section contains three
(3) refrigeration valves that must remain closed until
proper installation of the line sets is completed.
Disconnect electrical power to the ice machine head
section and remote
proceeding.
Step 1 Verify Ice Machine and Remote Condensing
Unit Locations Are Within Guidelines.
Prior to installation of the ice machine head section and
remote 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 remote condensing unit.

A. LINE SET LENGTH
100 feet (30.5 m) Length: The maximum measured
length the line set can be.
The receiver is designed to hold a charge sufficient to
operate the ice machine in ambient temperatures
between -20°F (-28.9°C) and 130°F (54.4°C), with line
set lengths of up to 100 feet (30.5 m).The maximum
amount of lineset which can be exposed on the rooftop
is 25% of the total length of the lineset.
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!
B. LINE SET RISE OR DROP
before
35 feet (10.7 m) Rise: The maximum distance the
remote condensing unit can be above the ice machine.
15 feet (4.5 m) Drop: The maximum distance the
remote condensing unit can be below the ice machine.
