Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.

The suggested shortest pipe length is 1.5 m, in order to avoid
noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how
the unit is installed and the environment in which it is used.)
