Connection of Indoor and Outdoor Unit
Caution:
● For multi-split air conditioner system, each pipe shall be pasted with label to identify the pipe for each
system and avoid wrong connection.

Installation of Protective Layer on Connection Pipe
1. To avoid condensate dew or water leakage on connecting pipe, the high pressure gas pipe, low pressure
gas pipe and liquid pipe must be wrapped with heat preservation material and adhesive pipe for insulation
from the air. High- pressure gas pipe should be covered with heat insulator which can endure at 120 or
℃
higher.
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.
无间隙
Caution:
When the pipe is properly protected, do not bend it to a very small angle; otherwise the pipe
might crack or broken.
3. Wrap the pipe with tapes.
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.
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.
☆
Caution:
Do not wrap the protective tape too tightly, as this will decrease the heat insulation performance. Ensure
☆
that the drain hose of condensate water is separated.
☆ After completing the protection work and wrapping the pipe properly, close the wall holes with sealing
materials.
