NOTE
Replacement filters can be ordered separately.
Never operate the air conditioner without a filter. This
can cause fouling of the heat exchanger and lead to a
loss of power.

l Change the remote control batteries (2 x AAA type) when
the display of the remote control becomes unreadable
and / or blurry.
l Remove the batteries from the remote control if the remote
control is not used for a long time to prevent damage to

ularly to ensure good performance. Minimally run the unit every
6 months for at least for 20 - 30 minutes.
7.5 Cleaning

of the outdoor unit.
