PROBLEM
Unit emits odor during operation
Compressor does not immediately
activate when power button is
pressed ON
The unit deactivates
The unit does not cool
satisfactorily
ERROR CODES
E1

SOLUTION
Odor development can arise upon
rst use and after a long period
of non-use by storing in unsuitable
areas (e.g. dusty areas). Run the unit
for ½ a day. The smell will dissipate
after awhile. In the case of intense
odor development, air the room.
After pressing Power button ON,
the compressor will not start for 3
minutes. Conditioned air will start to
blow once the compressor starts, but
it may take up to another 5 minutes
to feel the cooling or warming
eect in the room.
Upon reaching the set temperature,
the unit switches o automatically.
Check temperature setting.
Air conditioners operate more
eectively if a cooler room
temperature is maintained. To
adequately cool the air in a very
warm room requires much more time
and energy.
Move unit indoors.
If the error code continues to
appear, call 1-800-469-4663 to
arrange for product inspection and
repair.

If the water tank is full, the warning
sign “E4” appears in the display. To
restart operation of the unit, please
remove the plug of the lower drain
outlet to allow the water to drain
out. Please use an appropriate
collection pan. When the water
has been completely removed, start
the unit again. The unit can now be
used as usual.
This procedure is completely normal
and protects the system from
icing and failure. The unit starts
automatically after approx. 15
minutes (depending on the function
setting). This procedure repeats itself
regularly.
