6.9 Exhaust system
Install exhaust pipes as straight and with as few bends as
possible. Install the supplied silencer horizontally after the first
90 °-bend seen from the engine outlet.
Arrange the exhaust system so that no condensation water can
enter the engine. Attach the exhaust system to the building.
Connect the exhaust pipe to the flexible exhaust port of the
engine. The exhaust port is covered for transportation by a plastic
plug which must be removed before connecting the exhaust pipe.
See arrow in fig. 19. The flexible connection on the engine must
not be used to compensate for misaligned pipework.
The minimum diameter of the exhaust pipes must not be smaller
than the exhaust port of the engine.

Exhaust port of the engine
Note
This section applies to pump sets with diesel
engine.
Warning
Exhaust must be directed safely to the open air
through the exhaust system.
Exhaust must not escape indoors.
Operation without an exhaust system is not safe.
Warning
Make sure that persons cannot accidentally come
into contact with hot exhaust pipes.
Warning
When welding the engine exhaust pipe to the
main exhaust pipe wear, use the following:
protective gloves, protective clothes suitable for
the work, an approved safety helmet for welding
and safety shoes.
Warning
The exhaust flange seal must be mounted and the
flange must be tightened to 220
Nm.
Retighten all flange bolts after commissioning
and cooling down.
Note
The diameter of the exhaust pipes depends on
the pipe length, the type and number of silencers
and the bends, as all will affect the flow
resistance. In order not to exceed the exhaust
counterpressure specified by the manufacturer of
the diesel engine, it may be necessary to use
pipes with a nominal diameter one or two sizes
larger than the engine outlet.
