28 Part Number 000014141 Rev06 9/19
Installation Section 2
When lengthening or shortening lines,
follow good refrigeration practices, purge
with nitrogen and insulate all tubing. Do
not change the tube sizes. Evacuate the
lines and place about 5 oz (145 grams) of
vapor refrigerant charge in each line.
1. Remove the dust caps from the line
set, condenser and ice machine.
2. Apply refrigeration oil to the threads
on the quick-disconnect couplers
before connecting them to the
condenser.
3. Carefully thread the female fitting to
the condenser or ice machine by hand,
then tighten the couplings with a
wrench until they bottom out.
4. Turn an additional quarter turn to
ensure proper brass-to-brass seating.
Torque to the following specifications:
Liquid Line Discharge Line
10 - 12 ft lbs
13.5-16.2 N•m
35 - 45 ft lbs
47.5-61.0 N•m
5. Check all fittings and valve caps for
leaks and reinstall and tighten caps.
6. Interconnecting line voltage wiring
is used to energize and de-energize
the condenser fan motor. The remote
condenser voltage matches the ice
machine head section voltage.

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.
