The sound pressure level was measured without a silencer
1 metre away from the unit.
The dimensions of the silencer delivered from
factory are designed to meet the sound pressure
level requirements at the installation site.
Note
The site or the required sound pressure level
must therefore be specified when placing the
order.
Warning
The sound pressure level when the engine is
running is >70 dB(A). Hearing protection must
therefore be worn when working on or near the

engine.

Mixture of 50 % coolant and
50 % water.
Ethylene/glycol-coolant according
to ASTM D4985.
Never use conventional engine vehicle coolants.
They can damage the engine due to their high
silicate content!
