n 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.
