Concealed Duct High Static Pressure
Installation Manual
Duct design
1. In order to prevent short circuits, design the duct work, 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 (Procured locally). 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
Duct connecting of all units except outdoor unit are procured and enforced in locally.
