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.

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 them 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 120°F (48.9°C), with line
set lengths of up to 100 feet (30.5 m).The maximum
amount of line set which can be exposed on the rooftop
is 25% of the total length of the line set.

B. LINE SET RISE OR DROP

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.

!

Warning

The QuietQube Condensing unit contains refrigerant
charge. The two refrigeration valves must remain
closed
until proper installation of the line sets is
completed.

!

Warning

Disconnect electrical power to the ice machine head
section and remote condensing unit before
proceeding.

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!
