Installation
Refrigerant gas pipe connection
The standard length of the refrigerant pipe is 5m. If the distance between inside and outside is greater
than this, it will be necessary to extend the pipe.
Refer to the table below for the limitations of each unit in terms of maximum distance and height.
Do not exceed these limits or compressor failure may occur.
Keep the pipe separation length and number of elbows to a minimum and always follow the shortest
route for pipe installation.
As pipe length and number of elbows increase, unit performance decreases and energy consumption
increases.
As refrigerant pipe only phosphor copper pipe, deoxidised, seamless, of suitable quality for R410a must
be used.
-Requirements for the connection pipe between the indoor unit and the outdoor unit:
1.The machining dimension of the ared pipe section is as shown in the following table;
2.When connecting the are nut, refrigerant oil should be applied on the are pipe section (both inner
and outer wall), and screw the nut by screwdriver for 3-4 thread steps before nally tightening the nut;
3.The tightening torque is shown in the following table;
4.Carry out the leakage test after completion of installation.
Precautions:
1.Horizontal piping should slope towards the outdoor unit with a slope of 20:1.
2.If there is a height difference between the indoor and outdoor unit, oil traps should be installed in the gas interconnection pipe
(large):
When the vertical pipe height difference is less than 5m, an oil trap should be installed at the bottom of the gas pipe (large). When
the vertical pipe height difference is more than 5m, an oil trap must be installed at the bottom of the gas pipe (large) and a short
ring must be installed at the outlet of the liquid pipe (small) of the indoor unit every 5m:
When the vertical height difference of the connecting gas pipe is less than 5m, but the constant rise distance is too long, an oil trap
should be installed on the (large) gas pipe every 10m.
3.When the outdoor and indoor units are at the same elevation, it is not necessary to install the oil reservoir elbow and liquid ring, if
the horizontal length of the connecting pipe is less than 10m. When the horizontal connecting pipe length is longer than 10m, install
an oil sump on the gas pipe (large) every 10m.
Note: This table is for explanatory purposes. An actual installation may differ from this and must take into account the site condi-
tions. When making an oil trap, the radius of the bend should be between 1.5 and 2 times the pipe diameter.
