7.4.6 First filling and ventilation of the internal cooling water circuit
ATTENTION!: Risk of scalding.The expansion tank is supplied with a pressure relief
valve in the cap with 500 mbar. It is possible when
operating the generator hot cooling water can leak here
if there is an overpressure. When working always wear
protective clothing and ensure an adequate installation
location.
Fig. 7.4.6-1: Expansion tank1. Fill up the external cooling water expansion tank with
coolant.
ATTENTION: Maximum fill level = „max.“- marking
The cover of the external expansion tank must be opened
temporarily (all other closures are now closed!).

2. Start the water pump.
The electrical water pump can be started with the „Prime
Fuel“ option in the iControl panel, see “Priming the fuel
system ("Prime Fuel")” on page 122.
Fig. 7.4.6-2: Venting screw at the thermostat housing3. Open venting screw at the thermostat housing. Close the
vent screw when air free water comes out.
Check the water level in the expansion tank during the
venting. Fill up if necessary.
4. Start the generator
After filling the generator must be started. During this first phase of start-up, the generator may not be loaded.
Switch off the generator after approx. 10 seconds of operation!
5. Repeat the steps 1-4 till no more air comes out of the venting screw at the thermostat housing.
Close the venting screws.
6. Run the generator at idle speed till the cooling water temperature at the engine reach 60°C. Stop the generator.
Fill up the expansion tank up to max. marking.
Close the expansion tank.
7. Re-ventilating process 10 operating hours after the first start-up (and if necessary).
Also after the first initial operation a small amount of air may reside in the cooling circuit. To ensure an immaculate
und actual operation of the cooling system the ventilating process must be repeated casual in the next few days
(weeks, if necessary). Small amount of air will still exit out of the ventilating openings, especially if the generator
