5.4.3.2 ALDE- heater (optional)
Fig. 81: ALDE heater
The ALDE heater (optional) with hot-water heater is a classic
heating system similar to systems used in many households.
It comprises a boiler operated with standard camping gas
cartridges heating a glycol-water mixture and conveying the
same into a closed circuit with convector elements (heating
elements), recirculating pump and expansion vessel.
The ALDE system additionally features a 230 V electric heater
for fast heating of the parked vehicle, if required.
In many countries, the operation of gas heaters
during driving is not allowed. Before starting the trip,
obtain information about the locally applicable
regulations on the transit route and at the destination.
If in doubt, close the gas heater prior to starting the
trip, as well as the quick closing valve and gas bottle
valve.
NOTE
Appropriate maintenance is important to protect the
ALDE heater from damage.
• Replace the glycol/water mixture every two years
to prevent rust in the heating system.
• Vent the system if the convector elements in the
vehicle heat up unevenly.
First vent the heating system in cold state. If the
result is unsatisfactory, vent the heating system in
warm state.
See chapter "Maintenance", section "ALDE heating
maintenance overview" for a table to record the
maintenance tasks performed.
