Cleaning and maintaining

➤ Clean the device according to fig. j, page 5.
➤ Never use detergents containing chlorine for cleaning and disinfec-
tion.
➤ Perform self-cleaning once a week: see chapter "Self-cleaning" on
page 7.
➤ 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).
