9-2-5. Piping and drain hose installation

<Piping and Drain Hose Forming>

*Since dewing results in a machine trouble, make sure to insulate both the connecting pipes. (Use polyethylene foam as insulating material.)

 

Open the air inlet grille upward and pull it toward

 

you.

2.

Remove the terminal cover and cord clamp.

3.

Insert the connecting cable (according to the local

 

cords) into the pipe hole on the wall.

4.

Take out the connecting cable through the cable

 

slot on the rear panel so that it protrudes about

 

15 cm from the front.

5.

Insert the connecting cable fully into the terminal

 

block and secure it tightly with screws.

6.

Tightening torque : 1.2 N·m (0.12 kgf·m)

7.

Secure the connecting cable with the cord clamp.
