Tighten the valve cover of the gas valve and liquid valve so as to check whether leakage occurred.
(3). Installation of Protective Layer of Connecting Pipe
To avoid generation of condensate on the connecting pipe and avoid leakage, the big pipe and the small
pipe of the connecting pipe must be covered by thermal insulation materials, be bundled by adhesive tape,
and be isolated from air.
The joint connecting to the indoor unit must be wrapped by thermal insulation material. There shall be no
gap between the connecting pipe joint and the wall of the indoor unit. Refer to Figure 3-1-6.
Figure 3-1-6 Figure 3-1-7
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 xed to wall using pipe clamps.
Caution:
After the pipes are wrapped by protective materials, never bend the pipes to form very small angle, and
Page 28
26
Condensing Unit
Service Manual
otherwise the pipes may crack or break.
Do not wrap the protective tape too tight, otherwise the efciency of thermal insulation may be decreased.
Ensure that the condensate drainage exible 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 connecting pipe is
needed to lengthen, appropriate amount of refrigerant should be added. How much refrigerant should be
added for every meter extension refers to the following table. Allowable maximum pipe length is 30m.
If height difference between indoor unit and outdoor unit exceeds 10m in installation of air conditioner, an
oil return bend must be mounted at an interval of 6m.
If heights of indoor unit and outdoor unit are different, pipes should be laid out with reference to Figure 3-2-
