How should I prepare the caravan for the travel season?
The following contains useful tips for restarting the heater, boiler etc. after the long winter break.
1. S-heater: (cleaning)
To do this, remove the cover from the heater.
Remove all dust deposits on the heat exchanger and base plate.
Use a small paint brush or brush to carefully remove any dust on the fan wheel of the Trumavent fan.
Also, check the exhaust cowl for damage and soiling (e.g. leafs).
1a. Battery in the automatic ignitor of the S-heater:
Insert battery – if you cannot hear a sparking sound, or only at intervals of more than one second, the battery needs to be replaced (only when the heater is switched off)
Only use temperature-proof (+70°C) leak-proof Mignon batteries, other batteries may cause malfunctions.
2. Storage Waterheater
Check the waterheater for leaks.
If there are any leaks, the inner tank can be replaced, either by our mobile service or an authorised Truma service partner.
Anyone who wants to tackle the replacement themselves, can do so by following instructions.
3. Controller system:
Connect the pressure controller, or high-pressure hoses to the gas cylinder.
Set the optionally installed gas remote switch to ON.
Place the batteries into the remote control.
5. On-board battery:
Charge the battery. Please note that the battery is only fully charged after 24 hours.
During charging, please remember to adapt the charging voltage to the battery temperature.
Depending on the type, batteries will warm up more or less. Also, the direct ambient temperature of the battery has a significant influence on the performance.
If a battery temperature sensor is attached, it will record the operating temperature of the battery and will communicate this to the connected charger. The charger then changes the charging curve based on the sensor measurements.
This means, the higher the operating temperature, the lower the output voltage; and the lower the operating temperature, the higher the output voltage.
Note: The operating temperature range of our charging systems is 0°C to + 50°C.
If 50°C is exceeded, the charging process is interrupted.
Using a battery temperature sensor is not only beneficial for the battery, it also increases its service life.
Truma wishes you a pleasant summer season!
