Duct design

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.
Always install the air filter (Local procure) in a
location that permits easy maintenance, such as
behind the intake grille. (If no air filter is installed,
dust will collect in the heat exchanger, which may
cause the air conditioner to fail or to leak.)

Parts except air conditioner unit are to be locally procured.
