Duct design
1
In order to prevent short circuits, design the duct installation, so that the intake and discharge
openings are not adjacent to each other.
2
The indoor unit does not have a built-in air filter. Make sure to set up the filter chamber etc. and
install the air filter (Locally procured). If no air filter is installed, the heat exchanger will be blocked
by dust, which may cause the malfunction of air conditioner or the water leakage.

NOTE
All duct connection between units except outdoor unit must be procured and enforced locally.
