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.

!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.

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.

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!

B. LINE SET RISE OR DROP

35 ft. (10.7 m)

MAX.

DISTANCE

SV1751

35 feet (10.7 m) Rise: The maximum distance the remote condensing unit can be above the ice machine.

15 ft. (4.5 m)

MAX.

DISTANCE

SV1750

15 feet (4.5 m) Drop: The maximum distance the remote condensing unit can be below the ice machine.
