Indoor Unit
Installation
Step 4: Adjust the air inlet direction
(From rear side to under-side)
Step 3: Duct and accessories installation
NOTE:
1. Do not place the connecting duct weight on
the indoor unit.
2.When connecting the duct, use an
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.
1. Install the filter (optional) according to the size
of the air inlet.
5. Refer to the following static pressure guidelines
when installing the indoor unit.
Change the fan motor static pressure
according to external duct static pressure.
2. Install the canvas tie-in between the body and
duct.
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:

1. Take off the ventilation panel and flange.
2. Change the mounting positions of the
ventilation panel and air return flange.

3. When installing the filter mesh, fit it into the
flange as illustrated in the following figure.

slightly different in design, though similar in
shape.
