Installation
Route the Line Set
• Route the line set to avoid traps and
kinks.
• Minimize the amount of line set exposed
on the roof.
Connect the line Set
In most cases, by routing the line set
properly, shortening will not be necessary.
When shortening or lengthening is
required, do so before connecting the
line set to the ice machine or the remote
condenser. This prevents the loss of
refrigerant in the ice machine or condenser.
The quick connect fittings on the line sets
are equipped with access valves. Use these
valves to recover any vapor charge from the
line set. 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 145 grams (5 oz) 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.
