3. The air inlet and air outlet duct should
be far enough apart enough to a avoid
air passage short-circuit.
4. Connect the duct according to
the following diagram:

NOTE:
1. Do not place the connecting duct weight on
the indoor unit.
2. When connecting the duct, use a
nonflammable canvas tie-in to prevent vibrating.
3. Insulation foam must be wrapped outside the
duct to avoid condensate. An internal duct
underlayer can be added to reduce noise, if the
end-user requires.
4. The min. length of the duct should be more
than 1m, and fix on the air inlet by screws
(applicable to the unit that the air inlet filter is
not fasten by screws).
Step 4: Adjust the air inlet direction
(From rear side to under-side.)
