Maintenance

6.1

Air filter

The return air filter needs periodic maintenance.
1. Check and clean the filter every week, when in use, to pre-
vent the filter from being blocked by dirt.
2. You must wash the filter frequently to ensure effective
cooling and heating.
3. Remove the air filter from the air distributor by pushing
both tabs (1) inwards (2) and then downwards (3).

4. Lift the filter (1) upward and pull out of the air grille (2)
along the tracks.

5. Clean the filter and air grille with warm water and deter-
gent.
6. Let it dry before installing again.
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.
6.2

Remote control batteries

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
the remote control from leaking batteries.

6.3

Bolt check

Check the four bolts holding the unit to the roof for tightness 3
months after first installation of the product.
Inspect the bolts regularly; minimally every 12 months.
Retighten to 7 Nm if necessary.
6.4

Regular usage

Webasto recommends that you operate air conditioner regularly
to ensure good performance. Minimally run the unit every 6
months for at least for 20 - 30 minutes.
6.5

Cleaning

Regularly remove leaves or other dirt from the ventilation grilles
of the outdoor unit.
l Regularly clean the unit using a soft, damp cloth and mild
2
detergent.
l Clean the vehicle roof at regular intervals. A dirty roof heats
up more than a clean roof.
CAUTION
Never drive through automatic car washes with a roof
air conditioner installed.
Do not spray into the openings of the unit with a high-
pressure cleaner.
Do not use hot cleaners and steam cleaners.
Do not use sharp or hard objects for cleaning.
Never use petrol, diesel, solvents or aggressive cleaning
agents.
6.6

Heat exchangers

Minimally have your unit's heat exchangers cleaned by a spe-
cialist workshop once per year.

ject to European Directive 2006/66 / EC or
