Indoor Unit Installation

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 an 

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 Installation tips.)

5) Pass the interconnecting wires 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 interconnecting 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.
