12.5 Dometic air conditioning unit
A lint filter and an activated carbon filter are each located in the lower part of
the air conditioning system ceiling unit (Fig. 180,2) behind the ventilation grills
(Fig. 180,1 and 3). The lint filters must be cleaned at regular intervals and
replaced if necessary. The manufacturer recommends replacing the activated
carbon filter yearly.
On the left side of the ceiling unit (outside of the vehicle) is located the
drainage opening for the condensation. Keep the drain openings free from dirt,
leaves or similar to allow the condensation to be drained.
12.6 Winter care
De-icing salt damages the underbody and the parts open to water spray.
Dethleffs recommends to wash the vehicle more frequently during wintertime.
Mechanical and surface treated parts and the underside are under particular
strain, and should therefore be cleaned thoroughly.
12.6.1 Preparations
Check the vehicle for paint and rust damage. Repair damage as neces-
sary.
Make certain that water cannot penetrate the automatic floor ventilation
system and the heater.
Use a wax-based rust inhibitor to protect the metal parts of the underbody.
Use appropriate protection for external painted surfaces.

If there is any risk of frost, always operate the heater with approximately
15 °C and put the circulation fan in automatic mode. In the case of extreme
external temperatures, the furniture flaps and doors should be left slightly
open. The inflowing warm air can help prevent the freezing of water pipes,
for example, and counteract the formation of condensation in the storage
spaces.
If there is any risk of frost, cover the outside surface of the windows with
winter insulation mats.
Keep the waste gas vent and the skylights free from snow and apply a vent
extension of at least 10 cm (4 inches) in length.
