Test Run - LG LGRED LH188HHV1 Installation Manual

Finishing the Job
After the Triple Leak and Evacuation (and refrigerant trim charge, if any) procedures have been performed, follow the steps below to open
the refrigerant lines.
1. Verify that the auxiliary service port is removed (if used in the Evacuation procedure) and the original Schrader core was re-installed on
the gas (vapor) suction service port.
2. The service ports are a back-seated type with a right hand thread. Remove the service valve caps on both the gas (vapor) suction and the
liquid service ports.
3. Using an appropriately sized Allen wrench, fully open the valves on both the gas (vapor) suction and the liquid service ports by turning the
valve stem counterclockwise.
4. Turn until the valve stem is out, stops, and the valve is completely backseated.
5. Securely replace service port caps on both the gas (vapor) suction and the liquid using an adjustable wrench.
