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.

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).

          

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.

NOTE:

 All the figures in this manual are for

demonstration purposes only. The air 

conditioner you have purchased may be 

slightly different in design, though similar in 

shape.
