10. Connection of pipeline

10.1
Connection of Outlet Pipe for Indoor & Outdoor Unit
Align the expansion end of copper pipe with the center of threaded joint. Tighten the
flaring nuts with your hands.
Tighten the flaring nuts with torque wrench until you hear a "click".
Bend of fitting pipe shall not be too low; otherwise the fitting pipe might crack. Please use
pipe bender when bending the fitting pipe.
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.
Connecting pipe shall be supported by a rack without transmitting its weight to other units.
10.2
Installation of Protective Layer on Connection Pipe
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.
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.
Wrap the pipe with tapes.
1. Use the adhesive tape to wrap the connecting pipe and cable into one bundle. To
prevent condensate water from overflowing out of the drainpipe, the drainpipe shall
be separated from connecting pipe and cable.
2. Wrap the heat preservation tape so that each ring of tape shall press half of the
previous ring.
3. Fix the wrapped pipe onto the wall with pipe clamp.
4. Do not wrap the protective tape too tightly, as this will decrease the heat
insulation performance.
5. After completing the protection work and wrapping the pipe properly, close the
wall holes with sealing materials.
