7 Servicing
This section describes the servicing jobs that can be carried
out on the heater and its components when installed.
7.1 Working on the heater
Always disconnect the power supply at the vehicle battery
and remove fuses F2 and F3 before carrying out any work on
the heater. The main battery power must not be discon-
nected whilst the heater is operating or afterrunning due the
risk of the heater overheating and consequently the over-
heating safeguard tripping. Completely remove the heater to
carry out repairs.
Once the heater and all coolant-carrying components have
been installed, the entire coolant system should be filled, bled
and checked for leaks at the system pressure as specified by
the vehicle manufacturer (see Technical Data).
Refer to the general installation instructions and the vehicle-
specific installation instructions for repairs that require the
heater to be installed in a different position.
NOTE
Coolant running out of the system should be collected in a
suitable container.
7.2 Working on the vehicle
ATTENTION
With the operating voltage applied and the heater is
switched off, on no account must a temperature of 125 °C be
exceeded in the vicinity of the heater (e.g. vehicle paintwork)
(see Technical Data).
7.3 Heater test run
CAUTION
Even if you use the timer, the heater must not be operated in
enclosed spaces such as garages and workshops without an
emissions extraction system.
7.4 Checks
To maintain the functional reliability of the heater, the follo-
wing servicing jobs should be carried out before and after
each heating period:
• Read out fault code memory.
• Cleaning heater exterior (make sure no water gets in).
• Check the electrical connections for contact corrosion
and firm seating.
• Checking exhaust gas and combustion air line for dam-
age and ensuring they are clear.
• Checking fuel line and strainer for leaks.
• Check coolant circuit and coolant pump for leaks.
• Check hoses for cracks.
• Replacing fuel filter, if fitted.
• Check heater operation as described under section 6.2.
