SERVICE VALVES
These condensing units have service valves on the compres-
sor suction line and on the liquid line leaving the condenser
coil.
The liquid and suction line service valves are shipped from
the factory front-seated and closed with the valve stem in the
maximum clockwise position.
Start the compressor (after 8 hours of crankcase heat) and
continue to charge refrigerant gas through the access port on
the suction service valve until the correct charge is installed.
