How to replace the drain plug and drain hose
•
Replacing onto the left side
1)
Remove the insulation fi xing screw on the right to
remove the drain hose.
2)
Reattach the insulation fi xing screw on the right as it
was.
Forgetting to attach this may cause water leakages.
3) Remove the drain plug on the left side and attach it to
the right side.
4) Insert the drain hose and tighten with included
C
indoor unit fi xing screw.
How to set drain plug
No gap.
Do not apply lubricating oil
(refrigerant oil) to the drain plug
when inserting it.
The application of lubrication oil to
the drain plug will deteriorate the
plug to cause drain leakage from
the plug.
Insert a hexagon wrench (4mm).
Drain hose attachment position
The drain hose is on the back of the unit.
