Use adhesive tape to bundle the connecting pipe and the cables together. To prevent
condensate from overflowing out from the drainage pipe, separate the drainage pipe firm the
connecting pipe and the cables.
Use thermal insulation tape to wrap the pipes from the bottom of the outdoor unit until the
upper end of the pipe where the pipe enters the wall. When wrapping thermal insulation tape,
the later circle of tape must cover half of the front circle of tape (Figure 3-1-7).
Wrapped pipe must be fixed to wall using pipe clamps.
Caution:
After the pipes are wrapped by protective materials, never bend the pipes to form very small
angle, and otherwise the pipes may crack or break.
Do not wrap the protective tape too tight, otherwise the efficiency of thermal insulation may
be decreased. Ensure that the condensate drainage flexible tube is separate from the bundled
pipes.
After the protective work is completed and the pipes are wrapped, use seal material to block
the hole in the wall, so as to prevent rain and wind from entering the room.
3.2 Caution in Connecting Pipes
Arrangement of connecting pipes shall be performed according to sit conditions with reference to
the following principles.
Try to shorten the length of connecting pipes, within 5m for the better.
Try to reduce height difference between indoor unit and outdoor unit.
Try to reduce number of joint bends of connecting pipes.
If the length of connecting pipes is more than 20m, adequacy of lubricant of the system must
be checked; and if necessary, add more lubricant properly.
Filling amount of refrigerant in the system is matched to a 7m connecting pipe. If the
