(4) When connecting outdoor and indoor unit, never pull the big and small joint of indoor unit with force, so as
to prevent the tubes of indoor unit from cracking and causing leakage.
(5) Connecting pipe shall be supported by a rack without transmitting its weight to other units.
8.2 Installation of protective layer on connection pipe
(1) To avoid condensate dew or water leakage on connecting pipe, the air pipe and liquid pipe must be
wrapped with heat preservation material and adhesive pipe for insulation from the air.
(2) The joints on indoor unit and outdoor unit must be wrapped with heat preservation materials and have no
clearance against the wall surface of indoor unit and outdoor unit.
(3) Wrap the pipe with tapes.
Use the adhesive tape to wrap the connecting pipe and cable into one bundle. To prevent condensate

Wrap the heat preservation tape so that each ring of tape shall press half of the previous ring.
Fix the wrapped pipe onto the wall with pipe clamp.
Do not wrap the protective tape too tightly, as this will decrease the heat insulation performance.
After completing the protection work and wrapping the pipe properly, close the wall holes with sealing
materials.
