3.2.3.1 Installation Notice and Requirement on Connection Pipe
Due to product improvement, there are currently two installation methods for
the pipe connecting nut of indoor unit using R32 refrigerant. Product performance
will not be affected.
(1) Installation of removal-proof Nut
Unfold the connecting pipe and bend the connecting pipe according to the
required length. Open the nut cover on the indoor unit’s pipe and align the conical
mouth of the connecting pipe with the center of the indoor unit’s pipe. Tighten the
nut by hand and then tighten it with a torque wrench. The indoor unit adopts a
special non-detachable connector, which is installed in the same way as the
common connector. Once installed, it cannot be removed. If you need to break the
connection between indoor and outdoor units, cut the connector. Replace with a
new one and weld again.
