Truma UK would like to inform Practical Motorhome readers of a potential safety problem with gas filter cups fitted since the start of 2012. The gas filter cup is located between the gas bottle and the regulator.

Faulty processing in Truma’s supply chain has resulted in the possibility of a material fault in the windows of the gas filter cup. This can allow gas to escape freely into the atmosphere via the cylinder box. In unfavourable circumstances, this might cause gas deflagration and injuries, although Truma wants to state that it is not aware of any cases where this has happened. 

To avoid any risks, Truma has therefore decided to replace all filter cups in the market with a new version. The rest of the filter body assembly is unaffected and will not impact on anything surrounding or connected to it, such as the hose or the regulator. 

The probability that the material fault will present itself is very low; however, motorhome owners who have a Truma gas filter fitted in their vehicle must take the following precautions: 

  • Shut down the gas system immediately 
  • Contact your dealer or Truma and order new filter cups free-of-charge 
  • Replace old filter cups with new ones

     
Customers can replace the cups quickly and easily themselves. The gas supply needs to be closed before the part is replaced. Then the old filter cup can be unscrewed – like when replacing the filter cartridge – and the new filter cup screwed on. To see how it’s done, watch this helpful video.
