Installation Instructions
2. Open the venting screw at the pipe socket of the internal
cooling water pump until bubble-free coolant escapes.
Close the vent screw.
(not existent at all models)
Check the water level in the expansion tank during the venting.
Fill up if necessary.
Never open the vent screw while the generator is running because water
may be sucked into the cooling water circuit.

3. 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.
Fill up the expansion tank up to max. marking.
Close the expansion tank.
6. 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 imaculate 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 stood still for
a long time.
During the ventilating process repeated checks must be made
to check the cooling water is indeed circulating. If there are air
bubbles in the internal cooling water pump, it is possible that
the cooling water is not circulating. The generator will heat up
very quickly and switch off, because of overheating.
ATTENTION: Check circulation
