Section 2 Installation Instructions

Part Number 000001530 2-13

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.

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 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.

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 (49°C), with line set

lengths of up to 100 feet (30.5 m).

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.

Warning

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.

Warning

Disconnect electrical power to the ice machine head

section and CVD® 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! Refer to factory equipment refrigerant

amounts on previous page for details.
