4. Start the generator
After filling the generator this must be started. During this first phase of start-up, the generator
may not be loaded. Switch the generator off after max. 2 minutes of operation!
5. Repeat the steps 1-4 till no air comes out of the vent screw at tthermostat housing.
6. Close the vent screws.
7. Fill up the expansion tank.
8. Close the expansion tank.
7. Re-ventilating process after 10 operating hours of the first start-up (and if necessary)
Also after the first implementing a small amount of air can be reside in the cooling circuit. To
ensure an imaculate und actual operating 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.
ATTENTION! During the ventilation process it must be checked again and again if the coo-
ling water is indeed circulating. If air bubbles established in the internal cooling water
pump, it could be, that the cooling water circuit is not circulate. Then the generator would
be warming very fast and switched off by overheating.
Anti-freeze
In the interest of safety, the freezing point of the closed circuit coolant should be checked on a
regular basis. Be sure that the coolant/antifreeze mixture is good for at least -15°C (5°F) and if it
is possible that your genset experiences lower temperatures, for example during storage or trans-
portation, then the entire cooling system should be drained and purged.
5.4.3 Pressure test for control of cooling water circuit
Check with the hand if a temperature difference exists whether between cooling water in-flow and
cooling water return.
Feel the cooling water in-flow line at the internal cooling water pump.
Feel the cooling water return pipe either at the outlet of the water-cooled exhaust elbow union or
at the side, where this pipe entry at the heat exchanger.
The temperature difference between in-flow and return is approx 10 degrees.
