Connection of drain hose
• Insert the attached drain hose into the drain pipe connecting port on the drain pan up to the end.
• Fit the attached hose band to the end of the pipe connecting port, and then tighten it securely.
REQUIREMENT
• Fix the drain hose with the attached hose band, and set the
tightening position upward.
• As the draining is the natural water draining, arrange the pipe
outside of the unit on the down slope.
• If piping is performed as shown in the figure, drain cannot be
discharged.
Fit the attached hose band to the end of the hose,
lay down the knob, and then tighten hose band.

Attached drain hose
Confirm that soft hose is pushed in up to the end of the drain pan.
Connecting drain pipe
Connect the hard vinyl chloride pipe (locally procured) to the mounted drain hose which
was attached.
In case of taking pipe from the left side
In case of taking pipe from the left side, exchange the plug from left to right. Push in the
plug of which end is not sharp up to the end.
Drain up
When a down-gradient cannot be secured for the drain pipe, drain-up piping is possible.
