12.5 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.
12.5.1 Preparations
Check the caravan 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.
12.5.2 Winter operation
During winter operation, condensation develops when the caravan is occupied
under low-temperature conditions. To ensure good interior air quality and
avoid vehicle damage from condensation, sufficient ventilation is essential.
Attach vent extension with a length of at least 10 cm.
When heating the vehicle, the heater should be at the highest setting and
roof storage cabinets, curtains and blinds should be opened. This ensures
optimal ventilation.
If the vehicle is equipped with a circulation fan, always switch the fan on
when the heater is on. There is danger of overheating for the heater!
In the morning, lift up all cushions, air out storage boxes and dry any damp
areas.
12.5.3 At the end of the winter season
Thoroughly clean the underbody. When this is done, corrosion-inducing
anti-freeze agents (salts, alkaline residues) are removed.
Clean the exterior and use regular car wax to protect metal surfaces.
Remove vent extension.
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.
If condensation has still developed, just wipe it off.
