stood still for a long time.
ATTENTION! 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 could be that the cooling water is not circulating. The
generator will heat up very quickly and switch off,
because of 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 transportation, then the entire cooling system should be drained
and purged
6.6.1 Pressure Test for Controlling the Cooling Water Circuit
Check if a temperature difference exists between cooling water in-flow and cooling water return flow by use of the
hand.
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 exits at the heat exchanger.
The temperature difference between in-flow and return should be approximately 10 degrees.
