Connection of the Refrigerant Pipe
Double-span should be used when connecting the pipes.
The wrench torque follow the below table:

(N.m)
Wrap the connecting pipes and cables together with tape,
but not including the drainage pipe. Drainage pipe can be
fixed along them separately.
Wrapping from the joint of outdoor unit to that of indoor unit,
each round of tape should cover half of its previous one.
Wrap the piping

CAUTION
REFRIGERANT PIPE INSTALLATION
Ventilate the air if there was any refrigerant leakage during the installation.
Make sure there is no refrigerant leakage after the installation.
Leaked refrigerant will generate poisonous gas if meeting fire.
