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.
