The Air Top 2000 ST heater is switched on and off by hand using a switch. Automatic
controls must not be used.
In class FL vehicles these heaters must not be used during loading and unloading
procedures or at loading points.
In class FL vehicles the heaters are switched off automatically and the combustion air
supply is interrupted for a maximum of 40 seconds if:
– the vehicle's engine is at a standstill; in this case the heater can be switched on
again by hand.
– a pumping device that is part of the vehicle is started. The control unit is then in fault
lock-out mode.
The ON/OFF switch must be set to OFF before the heater can be restarted.
