General repair instructions
If the air conditioning system had been opened for
l
repair work, a new drier should be installed in the re-
frigerant circuit.
After completion of repair work screw locking caps
l
(with seals) on all valve connections service con-
nections.
Before start up of the air conditioning system after a
l
new filling: - Turn the compressor approx. 10 revo-
lutions by hand using the clutch or V-belt pulley of
the magnetic clutch. - Start the engine with the com-
pressor/control valve switched off. - Once the idle
speed of the engine has stabilized switch on the
compressor and run it for at least 10 minutes at idle
speed and maximum cooling power.

Notes on cleanliness for Common Rail
engines
Special requirements with respect to cleanliness in
the fuel system do apply for commissioning, mainte-
nance and repair work, particularly for engines with
the Common Rail System. Contamination like dirt,
welding residues or similar can lead to the failure of in-
dividual components and adversely affect engine op-
eration.
Fig. 1
Spare parts should be left in their original packaging
l
as long as possible and should only be unpacked
just before use.
When parts are unpacked any connections must be
l
closed with suitable plugs or caps, in order to pre-
vent (Fig. 1) contamination of hose connections. If
e.g. fuel hoses are connected to one side, while the
second side cannot yet be connected, there is a
danger of dirt entering into the system. The free
connection must in this case also be appropriately
closed.
Notes and measures to be applied before starting
work in the fuel system
The fuel system must be closed. Visual examination
l
for leaks / damage in the fuel system.
Before starting work in the fuel system clean the
l
complete engine and the engine compartment with
the system still closed.
The engine should be dry before work is started in
l
the fuel system.
