Truma Therme

The intended use can be found in the respective operating instructions for the appliance. In principle, our appliances are approved for installation in caravans (vehicle class O) and mobile homes (vehicle class M1).  If vehicle class O is available for the mobile home and the installations comply with the applicable standards (e.g. gas installation in accordance with DIN EN 1949), a Truma appliance can be installed. Usually, mobile homes do not have road approval, so new installations of our units are not permitted.

If you are not using the vehicle, you should always drain the Therme in frosty conditions.

To prevent frost damage to the Therme, we advise the following:

1. The caravan should be horizontal while the water is being drained.
2. First, disconnect the power to the water pump (main switch or transformer).
3. Drain the water from the tank or remove the water pump from the tank.
4. Open the taps in the kitchen and bathroom and, if present, set the premixer valves to warm.
   Completely open the drain and aeration valves and pull them out.
5. Check that all the water has drained (5 litres). Our tip: this is best done with a 5-litre bucket or a container with a scale. Depending on the size of the caravan, this volume may be greater because of the water in the hoses in the vehicle.
6. You can also drain remaining water from the appliance by blowing into the open tap – at the warm setting.

Remember that we do not accept warranty claims for frost damage.

With the hose clips SC (part no. 40711-00) you can clip the water hoses to the warm air ducts to protect them against frost damage. The hose clips are simply clipped beneath the warm air duct clamps.

Close the drain and aeration valves (4) completely.

With premixers
Set the control button (2) of the premixer valve all the way to the red symbol (hot).

With mixer tap(s)
Open the hot water tap of the hot/cold water mixer tap or set the mixer tap to “warm”.

Leave the fitting(s) open until the Therme has been filled by displacing the air and water is flowing.

The Truma Therme should be sterilised and descaled regularly. All cleaning products from camping specialists are suitable for cleaning, sterilisation and care.   To descale the Therme, commercial descaling products, vinegar essence or citric acid can be used.   become. Fill the water container with cleaning or descaling products in the correct mixing ratio via the water inlet and allow them to work. Then rinse the water container thoroughly with clean water.     In addition, you can regularly make the water in the Therme hot tub hot to 60 °C to prevent microorganisms from colonising. There must be no cleaning products in the water container at this time. To do this, please switch on the device, leave it switched on for at least 50 minutes and do not draw any hot water during this time.
