  Secure the hanging bolts (M10, locally purchased) firmly in a manner capable of supporting the unit weight. 

  Consult your construction or interior contractor for details on finishing the ceiling opening. 
 

 

  Ensure the range of unit external static pressure is not exceeded. Refer technical manual for the range of 

external static pressure setting. 

  Connect the duct as shown. 

  When attaching duct to the intake side, remove the product filter frame assy and replace with locally purchase 

intake-side flange by using flange by using 10 - Ø 3.1(hole) screws. 

  Wrap the flange and duct connection area with aluminium tape or similar to prevent air leak.

When attaching a duct to the intake-side, be sure to attach 
an air filter inside the air passage on the intake-side. 
(Use an air filter with dust collecting efficiency at least 50% 
in a gravimetric technique.)

  Attach the nuts and washers to the hanging bolts, then lift up and hook the main unit onto the hanging fixtures. 

  Check if the unit is leveled using a level or a vinyl hose filled partially with water.

1  Remove the remote controller 1 lower case. 

(Insert a flat-tipped screw driver or similar tool 
2 to 3 mm into one of the gaps at the bottom 
of the case, and twist to open. Refer to the 
illustration at right.) Be careful not to damage 
the lower case. 

2  Do not remove the protective tape which is 

affixed to the upper case circuit board when 
remove the remote controller lower case. 

3  Secure the lower case to an outlet box or wall. 

Refer to (A) or (B) instructions below 
depending on your choice of cable installation. 

4  Be sure to use only the screws provided. 
5  Do not over tighten the screws, as it may 

result in damage to the lower case. 

6  Connect the indoor unit and the remote 

controller 1. (Refer to the illustration) 

7  Insert firmly the connector of remote controller 

cable 2 to connector at control box of indoor 
unit. 

8  Fix the green wire from remote controller 

cable 2 to the grounding location provided

2  Secure the remote controller lower case to the outlet box with the two accessory screws 3. Make sure that 

the lower case is flat againts the wall at this time, with no bending. 

3  Pass the remote controller cable 2 into the box. 
4  Route the remote controller cable 2 inside the lower case through rear feeding-out direction. 
5  Insert firmly the connector of remote controller cable 2 to connector (CON1) in the upper case circuit board. 
6  Secure the remote controller upper case to the lower case with the tabs provided. 

 

When the wall is hollow, please be sure to use the sleeve for remote controller cable to prevent dangers caused by mice biting the cable.

1  Install the remote controller lower case to the wall with the two accessory screws 4. 
2  Fasten the screws properly until screw head is lower than the rib and reach the base of remote controller 

lower case to ensure they do not damage the PCB inside the remote controller 1. 

3  The feeding-out direction for the remote controller cable can be either via top, left or right side. 
4  Use nipper to cut a notch at the upper case. (Select the intended feeding-out position) 
5  Route the remote controller cable 2 inside the lower case in accordance with the intended feeding-out 

direction. (Refer to the illustration at below). 

6  Insert firmly the connector of remote controller cable 2 to connector (CON1) in the upper case circuit board. 

(Refer to the illustration) 

7  Secure the remote controller upper case to the lower case with the tabs provided.
