8-4-5. 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.)
1. Die-cutting Front panel slit
Cut out the slit on the leftward or right side of the front panel
for the left or right connection and the slit on the bottom
left or right side of the front panel for the bottom left or
2. Changing drain hose
For leftward connection, bottom leftward connection
and rear leftward connection’s piping, it is necessary to
change the drain hose and drain cap.
How to fix the drains cap
1) Insert hexagonal wrench (4 mm) in a center
head.

After scribing slits of the front panel with a knife or a
making-off pin, cut them with a pair of nippers or an
equivalent tool.

How to install the drain hose
•
The drain hose can be removed by take off
screw,
after that twisting and pulling.
•
When removing the drain hose, be
careful of any sharp edges of steel
