Filling the Boiler

If the interior temperature is below 0°C, heat the interior with the heater first. Otherwise, the safety and drain valve will open and drain the boiler.

Emptying the Boiler

• If temperature inside the vehicle is below 0°C: ensure that the safety and drain valve has released.
  If the vehicle is not used during the frost period, the boiler must be emp- tied.

Start after a long period of non-use

1. Check the cowl and remove the cover and any dirt (e.g. leaves, cob-webs, etc.).
2. Flush the boiler according.

After a long period of non-use, smoke or odours may develop for a few minutes due to dust or dirt.

• In this case, ensure that the interior is well ventilated and perform self-cleaning.

Cleaning and Maintaining

• Clean the device.
• Never use detergents containing chlorine for cleaning and disinfection.
• Perform self-cleaning once a week: see chapter “Self-cleaning”.
• If side cowl is positioned below a window: Check window switch operation as a pre trip or seasonal check.
• Check regularly, especially after long journeys, that the cowl and the exhaust duct are intact and correctly fixed.
• Operate the safety and drain valve regularly, at least twice a year, to remove limescale deposits and ensure proper function.
• Have the heater, its gas supply, the exhaust duct and the cowl checked by an expert in accordance with national regulations (e.g. in Germany every 2 years). If no national regulations exist that should be done at least every 2 years. The inspection must be certified on a test certificate (e.g. DVGW Work Sheet G 607 for vehicles in Germany).

Self-Cleaning

To clean the system against bacteria operate the heater for a few minutes at the highest temperature level for self-cleaning:

1. Set room temperature to max. value.
