Important instructions for operation
Safety checks before the start
After a lengthy period of non-use (summer months)
check that all parts fit securely (tighten screws where
necessary)..
Carry out a visual check of the fuel system for leaks.
Heating at high altitudes
When using the heater at high altitudes, please note:
• Heating at altitudes up to 1500 m:
– Unlimited heating possible.
• Heating at altitudes over 1500 mm:
– Heating is possible for short periods at this
altitude (e.g. driving over a mountain pass or
taking a break in a journey).
– in the event of a lengthy stay, e.g. winter
camping, it is necessary to adjust the fuel supply
to the altitude, please contact a JE partner for
further information.
Installation of an altitude kit
(Order No. 22 1000 33 22 00) enables operation of
diesel heaters at altitudes above 1500 m, even for a
lengthy stay.
Please note!
Initial commissioning
The following points are to be checked by the company
installing the heater during initial commissioning.
• After installing the heater, the whole fuel supply
system must be carefully vented: please refer to and
follow the vehicle manufacturer’s instructions.
• During the heater trial run, all fuel connections must
be checked for leaks and secure, tight fit.
• If faults occur while the heater is running, use a
diagnostics device to determine and correct the
cause of the fault.
Please note!
Please note!
During the initial start-up of the heater, odours can be
produced for a short time. This is fully normal during
the first few minutes of operation and does not
indicate a malfunction in the heater.
