Section 2 Installation Instructions
Part Number 000001528 2-15
Step 4 Connecting the line set.
To prevent oxidation of the copper, purge line set and
condensing unit with dry nitrogen while brazing.
Connect The Line Set To The Ice Machine Head
Section
The line set can be routed for entry through the top or
rear of the ice machine head section.
• Top routing requires the cover to be trimmed.
• Rear routing requires the use of the supplies 90°
elbows.
The line set shut off valves at the back of the ice
machine must remain closed and be protected from heat
during the brazing process. Wrap the valves in a wet rag
or other type of heat sink prior to brazing. Cool braze
joint with water immediately after brazing to prevent heat
migration to the valve.
Connect The Line Set To The CVD Condensing Unit
The compressor oil rapidly absorbs moisture. Be
prepared to complete line set installation and start your
evacuation process in order to minimize the time the
compressor is exposed to the atmosphere. (Maximum
amount of time the system can be exposed to the
atmosphere is 15 minutes).
CVD1475
The line set can be routed for entry through the rear or
left side of the condensing unit.
• Remove knockout for preferred location.
• Insert supplied plastic bushings in knockout holes to
prevent tubing from contacting sheet metal.
• Use the supplied 90° elbows to route tubing.
CVD1475 and CVD1476
• Cut the tubing ends of the suction and liquid lines
and braze the line sets to the condensing unit.
!
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
The condensing unit ships from the factory
pressurized with a 50/50 mixture of nitrogen/helium.
Bleed off pressure from both suction and liquid line
access ports prior to cutting into refrigeration lines.
