Unit Start Up
The system can now be opened to allow the refrigerant charge in the outdoor unit to be released into the line
set. The service valves require a 5 mm Allen wrench to undo the valve stems. Remove brass caps from the
service valves.
Open the SUCTION line valve first to prevent any possibility of oil clogged in the capillary tube
.
(This can occur if the liquid line valve is opened first with the rest of the
system in a deep vacuum)
LIQUID or GAS line can then be opened.
Check that both service valve stems are fully open and stop against the
valve body. Replace the brass caps and tighten them to prevent leaks.
