Prior to commissioning the engine
Prior to commissioning the engine for the first time, the
inner cooling circuit must be filled with cooling liquid.
In order to do so, the filler cap on top of the heat
exchanger housing must be removed and the drain
valve A on the engine must be opened. By opening the
valve, the cooling liquid can flow directly from the heat
exchanger housing into the cooling channels of the
engine.
The cooling system must be filled with 9 liters of
cooling liquid. You can fill the system with a ready-to-
use product, or prepare a mixture of 40% anti-freeze (on
the basis of ethylene-glycol) and 60% of clean tap
water.
Fill the system to about 1 cm below the bottom of the
filler pipe. The system will breathe automatically. Do
not forget to put the filler cap in place again and close
the drain valve on the engine.
Once the engine being commissioned and having run for
the first time, verify again the level of the cooling liquid
and top up, if necessary.
When a calorifier is installed and connected to the
engine (page 18), an additional expansion tank must be
installed When the calorifier is installed higher than the
engine, it will not bleed automatically when filling the
cooling system. Fill it separately to bleed the cooling
system completely.
