Instructions for connecting Piping to
Oudoor Unit
1. Unscrew the cover from the packed
valve on the side of the outdoor unit.
(See Fig. 5.9)
2. Remove protective caps from ends of
valves.
3. Align flared pipe end with each valve,
and tighten the flare nut as tightly as pos-
sible by hand.
4. Using a spanner, grip the body of the
valve. Do not grip the nut that seals the
service valve. (See Fig. 5.10).
USE SPANNER TO GRIP MAIN
BODY OF VALVE
Torque from tightening the flare nut can snap off
other parts of valve.
5. While firmly gripping the body of the valve, use
a torque wrench to tighten the flare nut according
to the correct torque values.
6. Loosen the flaring nut slightly, then tighten
again.
7. Repeat Steps 3 to 6 for the remaining pipe.
