1.2 Installation and Maintenance
(1) Always leave an inspection hole ( 18) to access the filter and Lossnay Core.

The main unit's supply outlet and suction inlet and the
room side and outdoor side positions cannot be
changed. However, the unit can be installed upside-
down, and installed as shown below. (This is
applicable when installing two units in one classroom,
etc.)

with independent multiple air-conditioner unit due to
their features such as improved controllability, energy
conservation and saving space.
For these types of air conditioning systems, combining
