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 condensing unit/ice machine operation

!Warning

The following instructions are provided as a general overview of a typical installation. Refer to the Installation, Use and Care Manual for step by step installation instructions.

!Warning

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

!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 set is completed.

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 120°F (49°C), with line set lengths of up to 100 feet (30.5 m).

Important

The 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’ (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’ (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.
