NOTE:
!
Set the rotary knob on the control element to the required temperature.
To prevent the hot and combustion air fan from blocking or scraping, ensure that
there are no objects on or against the heater before you switch it on.
!
NOTE for ADR operation only:
!
The Air Top 2000 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.

Failure to follow the installation instructions and the notes
contained therein will lead to all liability being refused by
Webasto. The same applies if repairs are carried out
incorrectly or with the use of parts other than genuine
spare parts. This will result in the invalidation of the type
approval for the heater and therefore of its homologation /
EC type licence.
Liability claims will only be accepted if the claimant can
verify that he has complied with the servicing and safety
instructions.
Liability claims:
The heat exchanger in the air heater can be used for a maximum of 10 years and
must then be replaced by the manufacturer or one of its contract workshops using
a genuine spare part.
If exhaust lines pass through areas used by personnel they must also be replaced
by genuine spare parts after 10 years.
Changes to the settings
on the control element
are implemented after
a delay.
