Indoor Unit Installation

• Remove the pipe port cover as shown below.
1) Cut off the pipe port cover from inside the front grille using a copping 

saw.
Apply the blade of the copping saw to the notch, and cut off the pipe 
port cover along the uneven inner surface.

2) After cutting off the pipe port cover, perform filing. Remove the burrs 

along the cut section using a half round needle file.

 CAUTION

• If the pipe port cover is cut off using nippers, the front grille will be damaged. Please do not use nippers.
• Wear gloves during the pipe port cover removal.

3-1. Right-side, right-back, or right-bottom piping

1) Attach the drain hose to the underside of the refrigerant pipes with 

adhesive vinyl tape.

2) Wrap the refrigerant pipes and drain hose together with insulation 

tape.

3) Pass the drain hose and refrigerant pipes through the wall hole, then 

set the indoor unit on the mounting plate hooks by using the   
markings at the top of the indoor unit as a guide.

4) Open the front panel, then open the service lid.

(Refer to preparation before installation.)

5) Pass the inter-unit wire from the outdoor unit through the 

feed-through wall hole and then through the back of the 
indoor unit. Pull them through the front side. Bend the ends of 
tie wires upward for easier work in advance. (If the inter-unit 
wire ends are to be stripped first, bundle wire ends with 
adhesive tape.)

6) Press the bottom frame of the indoor unit with both hands to 

set it on the mounting plate hooks. Make sure the wires do 
not catch on the edge of the indoor unit.
