Filling and de-aerating of the internal cooling water circuit
Fill up the external cooling water expansion
tank with cooling water
Note: "consider maximum level" according
to marking! The cover on the external cooling
water container must remain provisionally
opened (all other catches are
however now closed!).
Start of the generator
After filling the generator must be started.
During this first phase of start-up, the
generator may not be loaded. Switch the
generator off after maximally 2 minutes of period of operation again!
Note!
The external cooling water expansion tank may be filled in the maximum filling in the cold
condition only up to the "max" - marking.
First de-aerating
The cooling water circuit of the generator must be de-aerated now by multiple repeating of the deaerating
procedure. During the entire procedure the external cooling water expansion tank
remains opened (i.e. the cap must be removed).
After the first stopping of the the generator wait about one minute until the air in the cooling water
can be drop off and raise to the highest point (ventilation point).
Now open all three ventilation points one after another as long as cooling water exit. Then the closure
screw must be closed immediately. (Turn on only lightly to treat the thread.)
Pay attention that the external cooling water expansion tank is filled with enough cooling water
during the de-aerating. (If necessary refill over and over.)
One de-aerating step will be last as a rule max. 2 minutes and following steps contained:
1. The generator runs approx. 1 minute.
2. Stop the generator.
3. Hold on one minute for drop of air.
4. The collected air is led out over the two de-aeration points.
The ahead described de-aerating process must be repeated as long as after the stopping and
drop off air none air exit out of the de-aerating ports, only cooling water.
