Frequently Asked Questions
Q: Can I use Ultraheat with older Truma S heaters like the Trumatic S 3002?
No - Ultraheat can't be used with any S-heater built before 04/2012, nor with the Trumatic S 3002, S 3002 P, S 5002, S 2200, S 55 T, or S 3002 K / S 5002 K.
Q: What fan setting should be used during electrical mode?
On electrical mode, run the fan at level 3 or above (manual or automatic) to spread warm air through the vehicle quickly and evenly.
Q: Can the Ultraheat be operated separately outside of a Truma S-heater?
No - Ultraheat (the electric additional heater) is only approved for fitting and running inside a compatible S-heater, never on its own or outside a vehicle.
Q: What power settings are available on the Ultraheat?
The additional heater features three operating power levels: 500 Watts, 1000 Watts, and 2000 Watts.
Q: Can the S-heater run on gas and the electric Ultraheat together?
Yes - the S-heater can run on gas while the electric additional heater runs too, though the additional heater may cut out on its own to guard against overheating.

Frequently Asked Questions
Q: How do I winterise the water system before storing the vehicle for winter?
Empty the water system completely: leave both the fresh and waste tank drain taps open, along with every internal tap, and keep the pump running until nothing more comes through. If you're expecting particularly hard frost, it's also worth taking out the water filter on the pump's outlet side and clearing it of water while you're at it - a handy moment to give it a clean before next season too.
Pull the sink plugs so air can get into the system, flush the waste tank thoroughly to shift any debris, finish with a mild disinfectant flush, and leave the drain tap open.

N/A | Concertina blind or flyscreen has become stiff and difficult to operate | The mechanism has dried out or picked up dust/grit over time - these units need only light, occasional lubrication. | Apply a light lubricant to the mechanism. Avoid cleaning solvents or aerosols on the blind material itself, as it's a paper-type fabric that these can damage.
