Troubleshooting guide
The air conditioner
will not start.
• Is it plugged into a wall socket?
• Check that the wall socket is live.
• Does error code “P1” appear in the display? If this is
the case remove the lower drain cover (15) and drain out
any water. Make sure that all water is discharged.
• The room temperature is lower than the set temperature.
Adjust the temperature using [ Λ ] or [ V ].
Insufficient cooling. • Open windows or doors are allowing warm air in.
Close all windows and doors.
• There are other sources of heat present in the room.
Turn these off.
• The exhaust hose is not attached. See the
Connecting the exhaust hose section.
• The temperature setting is set too high.
Reduce the temperature.
• The air filter is clogged. See the Cleaning the filter
section above.
Noise and
vibrations occur.
Make sure that the air conditioner is placed steadily
on an even, level surface.
A gurgling sound
is heard.
This can often be explained by the natural movement of
coolant in the air conditioner. This is completely normal.
Error code E1 The temperature control sensor is out of service. Turn
off the air conditioner, pull out the plug and plug it in again.
If this does not solve the problem and the error code
appears again, contact a qualified service technician.
Error code E2 The evaporation sensor is out of service. Turn off the air
conditioner, pull out the plug and plug it in again. If this
does not solve the problem and the error code appears
again, contact a qualified service technician.
Error code E4 Incorrect or unreadable values on the display. Turn off the air
conditioner, pull out the plug and plug it in again. If this does
not solve the problem and the error code appears again,
contact a qualified service technician.
Error code P1 The air conditioner’s lower water reservoir is full. Unscrew
the lower drain outlet (15) and ensure that all water is
discharged§. If this does not solve the problem and the error
code appears again, contact a qualified service technician.
Note: Error codes are shown in order of priority (E4-E2-E1-P1) when several
error codes are displayed at once.
