Standard length of connection pipe: 5m, 7.5m,
8m.
Min. length of connection pipe.
For the unit with standard connection pipe of 5m,
there is no limitation for the min length of con-
nection pipe. For the unit with standard connec-
tion pipe of 7.5m and 8m, the min length of con-
nection pipe is 3m.
Max. length of connection pipe is shown as below.

The calculation method of additional refrigerant oil
and refrigerant charging amount after prolong-
ing connection pipe.
After the length of connection pipe is prolonged
for 10m at the basis of standard length, you should
add 5ml of refrigerant oil for each additional 5m
of connection pipe.
The calculation method of additional refrigerant
charging amount (on the basis of liquid pipe):
Confirm the pipe length according to the distance
of indoor unit and outdoor unit.
Cut the required pipe with pipe cutter.
The additional refrigerant charging amount in Sheet is
recommended value, not compulsory.
Improper pipe expanding is the main cause of refriger-
ant leakage. Please expand the pipe according to the
following steps:
Additional refrigerant charging amount=
prolonged length of liquid pipe × additional
refrigerant charging amount per meter
Basing on the length of standard pipe, add
refrigerant according to the requirement as
shown in the table. The additional refrigerant
charging amount per meter is different accord-
ing to the diameter of liquid pipe.
