when the notification is displayed.
▪ If the dirt becomes impossible to clean, change the air filter

Maintenance before a long stop
period
E.g., at the end of the season.
▪ Let the indoor units run in fan only operation for about half a day in
order to dry the interior of the units.
▪ Turn off the power. The user interface display disappears. When
the main power is turned on, the air conditioner will use some
power, even if it is not operating.
▪ Clean air filters and casings of indoor units. Contact your installer
or maintenance person to clean air filters and casings of the
indoor unit. Maintenance tips and procedures for cleaning are
provided in the installation/operation manuals of dedicated indoor
units. Make sure to install cleaned air filters back in the same
position.
