break the nut or damage the
refrigerant piping. You must not
exceed torque requirements shown
in the table above.
5.3 Instructions for connecting
piping to outdoor unit
1. Unscrew the cover from the packed valve on the
side of the outdoor unit.
2. Remove protective caps from ends of valves.
3. Align flared pipe end with each valve, and
tighten the flare nut as tightly as possible by

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.
A
CAUTION! Torque from
tightening the flare nut can snap
off other parts of valve.
