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.
