1 Introduction
Air Top 3500/5000 ST

Overheating
Keep hot air inlet and hot air outlet free of dirt and other
items. Dirty, blocked air lines can cause the heater to shut
down due to overheating.
After an overheating lock-out, check that the air system is
clear, remove any materials that may block the air current
and have any damage to the air lines repaired by an
authorised Webasto workshop. After this the heater lock-
out can be cancelled by switching it off and then on again.
If this action does not produce the required success (if the
heater overheats again) take it to an Webasto-authorised
workshop.
The air outlet jets or air vents with adjustable flaps must
always be opened to some extent so that the air current
through the heater is not completely blocked. It must be
impossible to close at least one air vent.
If the heater is installed in a storage area, you must
ensure that no inflammable substances are kept in this
area and that other material does not restrict the air supply
to the heater.
Air lines must be securely fixed to the heater (using pipe
clips, for example) and all other connection points (for
example vents).
IMPORTANT
The errors described below are to be avoided at all costs:
•
Do not stand on the heater or place or throw any
heavy objects on the heater.
•
Do not place any items of clothing, textiles or similar
materials over the heater or in front of the hot air inlet
and hot air outlet.
•
The current of hot air from the heater must not be
restricted or blocked by highly inflammable
substances or materials such as rags, cleaning wool,
etc.
•
Inflammable or explosive substances and gases must
not be placed near or in contact with the heater, the
hot air line, the current of hot air or the exhaust pipe.
•
The heater must not be cleaned with a high pressure
cleaner.
•
Do not switch the heater off at the main battery switch
or battery isolation switch since otherwise it is
possible that it may suffer long term damage if it is
switched off frequently using the battery isolation
switch and this can cause damage and negative
influences on the function of the heater.
NOTE
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 invalidates the type approval for the
heater and its homologation / EC type permit.
You must read the operating manual before starting the
heater for the first time.
