LENGTHENING OR REDUCING LINE SET LENGTHS
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 Schraeder 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 5 oz (143g) of vapor refrigerant charge in each
line.
CONNECTING A LINE SET
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.
4. Tighten the couplings with a wrench until they
bottom out.
5. Turn an additional 1/4 turn to ensure proper brass-
to-brass seating. Torque to the following
specifications:
6. Check all fittings and valve caps for leaks.
7. Make sure Schraeder cores are seated and
Schraeder caps are on and tight.
