Section 2 Installation
CONDENSING UNIT INSTALLATION
Step 1 Secure the Condensing Unit.
Through-holes are provided to secure the
condensing unit to a curb, rack or wooden
timber.
Step 2 Route the Refrigeration Tubing.
Route the refrigeration tubing between
the ice machine head section and the
condenser or CVD condensing unit.
• A suction line oil trap is required when
rise is more than 20 feet (6 meters).
• Only one trap is allowed in the line set.
• Shorten the line set as required, do not
coil line set.

• Maximum amount of time the
refrigeration system can be exposed to
the atmosphere is 15 minutes.
• Purge line set with dry nitrogen while
brazing.
• Shutoff valves for the line set on the ice
machine must remain closed and be
protected from heat during brazing.
• The condensing unit ships with a 50/50
mixture of nitrogen/helium.

Step 3 Pressure Test and Evacuate Line Set
and CVD Condensing Unit.
• Shutoff valves for the line set must
remain closed until pressure testing and
evacuation are complete.
• Valve core removal tools that allow for
removal and installation of the valve
cores without removing hoses for the
manifold gauge set are recommended to
decrease the evacuation time.
• Pressure test at 150 psi (1000 kPa) for a
minimum of 15 minutes.
• Minimum evacuation level is 500
microns.
Pressure test the line sets and CVD
Condensing Unit with 150 psi (1000 kPa) of
dry nitrogen. Add nitrogen at the shutoff
valves for the line set located at the back
of the ice machine head section or from
the access valves located in the CVD
Condensing Unit. Complete the pressure
test, verify no leaks are present and remove
the nitrogen from the system before
connecting the vacuum pump. Connect
vacuum pump and evacuate system to
