Step 3: Duct and accessories installation
1. Install the filter (optional) according to the size
of the air inlet.
2. Install the canvas tie-in between the body and
duct. The air inlet and air outlet duct should be
far enough apart enough to a avoid air passage
short-circuit.
3. Connect the display panel as described at page
12
4. Connect the duct according to the following
diagram:

NOTE:
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).
5. Refer to the following static pressure guidelines
when installing the indoor unit.
MODEL
(Btu/h)
12K
18K
24K
36K
48K
Change the fan motor static pressure
according to external duct static pressure.
NOTE:
1. Do not place the connecting duct weight on
the indoor unit.
2.When connecting the duct, use an
non ammable 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.

Step 4: Adjust the air inlet direction
(From rear side to under-side)
1. Take o the ventilation panel and ange.

Bend the rear ventilation panel 90 degrees
along the dotted line into a descending
ventilation panel.(some models)
2. Change the mounting positions of the
ventilation panel and air return ange.
3. When installing the lter mesh, t it into the
ange as illustrated in the following gure.
