Filter cleaning
The filter housing in the suction area of the Zenia heater must be cleaned from time to
time. After the integrated boost heater has been operating for 80 hours, the FILTER text
lights up as a reminder (see Step 1). The integrated boost heater will continue to run at
first but will be deactivated after a total of 100 operating hours and cannot be reactivated
until the filter has been cleaned and the system has been reset.
