a. Installation.
CAUTION
Using excessive force when opening or closing valves can cause damage to the valve seats.
NOTE
The compressor shut off valves can be adjusted to three positions, fully closed to block the
refrigerant tubes and isolate the compressor and service port, fully open to allow flow from piping
to compressor but not the service port, and cracked (one turn closed from fully open) to allow flow
from piping to compressor and service port on valve.
(1) Remove two shut off valve caps and turn the shut off valves fully counterclockwise to backseat them.
