tighten the nut then using a wrench to tighten the nut again, the tighten torque as follows figure.
◇
Take out the cover of the indoor unit gas valve and liquid valve, make the expanding right to the stop
valve of outdoor unit, using hands to tighten the nut then using a wrench to tighten the nut again, the
tighten torque as follows figure.
Equivalent pipe length conversion
Equivalent pipe length means converting pipe elbow to straight pipe length after considerate the pressure
loss.

Equivalent Oil Loop length
Sample:
ALCA-H42A5/C5 Actual Pipe length is 25 meters, Gas pipe diameter is 19.05mm. If there’s 5 bends and 2
oil loops during the installation, then the equivalent pipe length should be:
L=25+0.35×5+2.4×2=31.5(m)

Caution:
1.The standard Pipe length is 5m, if the pipe length is less than this then no additional charging is
necessary. If the pipe length is more than this then you should charge more refrigerant into the system
according to the above Charging Data
2.The thickness of the pipe is 0.5-1.0, bearing pressure is 3.040MPa;
3.If the connection pipe is too long, the cooling capacity and stability would be decreased. And the more
bend quantity, the resistance in the piping system would be bigger, then the cooling and heating capacity
would be decreased even lead to compressor broken. We suggest you to use the shortest connection
