* 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 3m, 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.)
In sites with poor drainage,
use block bases for outdoor
unit.
Adjust foot height until the
unit is leveled. Otherwise,
water leakage or pooling of
water may occur.
NOTE
• Installation shall be done by an installer, the choice of materials and installation shall comply with the applicable
