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.
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 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).
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
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.
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!
