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 130°F (54.4°C)*, with line
set lengths of up to 100 feet (30.5 m).
*CVD675/CVD1185/CVD2085 =
-20°F to 120°F (-29°C to 49°C)
CVD1486 = 50°F to 110°F (10°C to 43°C). The
maximum amount of lineset which can be exposed on
the rooftop is 25% of the total length of the lineset.
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!
