Maintenance
Have heating fluid changed by Dethleffs dealer at intervals of approximately
two years as corrosion-protection wears off after some time.
Top up heating system with a water frost protection mixture (60 : 40) only.
This mixture offers frost protection up to approx. -25 °C.When topping up
hot-water heaters that are connected to the engine's cooling circuit, please
observe the instructions in the instruction manuals of the manufacturers.
Further information can be obtained from the separate instruction manual

heater
Switch off the hot-water heater and allow it to cool down.
Check if the fluid level is between the marks "MIN" (Fig. 87,3) and "MAX"
(Fig. 87,2) on the compensator reservoir (Fig. 87).
13.3.2 Topping up heating fluid
Position the vehicle horizontally. This prevents the formation of bubbles.
Switch off the hot-water heater and allow it to cool down.
Remove panel.
Open the rotary lid (Fig. 87,1) on the compensator reservoir.
Slowly remove cover with circulating pump upwards.
Check anti-freeze with an anti-freeze hydrometer. The frost protection content
must be 40 % or correspond to a frost protection of -25 °C.
Fill water frost protection mixture slowly into the compensator reservoir.
The optimum fluid level is reached when the fluid in the compensator reservoir
is 1 cm above the "MIN" mark (Fig. 87,3).
