Heater air system (example)
Heater air system
The parts for the hot air system are included in the
scope of supply of the "Universal" and "Plus"
installation kits.
The "Plus" installation kit does not include the flexible
pipe Ø 75 mm or Ø 90 mm, these must be ordered
separately. The order no. is given in the additional
parts catalogue.
Danger!
Risk of burning and injuries!
• The hoses of the heater air system and the hot air
outlet are to be routed and fastened in such a way
that they pose no temperature risk to people,
animals or materials sensitive to temperature from
radiation / contact or blowing directly. If necessary,
a cover is to be fitted to the heater air system or
hot air outlet.
• The outflow hood must be fitted on the hot air
outflow side.
• A safety grid must be fitted to the heater air intake
side and outflow side if no air hoses are mounted,
to prevent any injuries from the heater air fan or
burns from the heat exchanger.
• High temperatures occur in the heater air system
during and after the heater has been working.
This is why it is important to avoid working in the
vicinity of the heater air system while the heater is
working. In such cases, switch the heater off
beforehand and wait until all parts have cooled
down completely.
If necessary, wear safety gloves.
Caution!
• The heater air intake openings must be arranged in
such a way that under normal circumstances, it is
not possible for exhaust from the vehicle engine and
heater to be sucked into the system, or for the
heating air to be contaminated with dust, salt spray,
etc.
• For circulating air, position the circulating air intake
in such a way that the outflowing hot air cannot be
directly sucked in again.
• In the event of possible overheating, it is possible
for local lot air temperatures of up to max. 150 °C
or surface temperatures of up to max. 90 °C to
occur immediately before the defect shutdown.
Therefore only temperature-resistant hot air hoses
approved by us must be used for the heater air
system!
• When checking the functions, the mean outflow
temperature measured after the heater has been
running about 10 minutes at approx. 30 cm from the
outlet should not exceed 110 °C (at an intake
temperature of approx. 20 °C).
• If there is a risk of the driver and passengers
touching the heater when the vehicle is being driven
normally, a contact protection device must be fitted.
