Proceed as follows (note: it is advisable for two people to perform this work):
Step Procedure
1
Connect the filling pipe to the cooling-water supply of the cooling
module.
Note: Make sure that there are no dirt deposits in the filling pipe;
rinse first.
Note: The cooling water is tinted due to formation of metal oxides in
the heat exchanger. The functional capability is not affected.
Note: Cooling water filling pressure > 1 bar (1000 hPa).
2
On the top of the heat exchanger: Unscrew cap on drain valve and
open vent cock (red).
3
Open drain valves (2) on gas sampling probe.
4
Slowly open the shut-off valve -J63 on the cooling module and
allow cooling water to flow in until cooling water appears at the
drain valves of the heat exchanger and gas sampling probe.
5
Close shut-off valve -J63.
6
Close drain valves on heat exchanger and gas sampling probe.
7
Check pressure of cooling water in the controller and top up if
necessary (target cooling water pressure in cooled state: 1-1.5 bar
(1000-1500 hPa)).
Proceed as follows:
Step Procedure
1
Check cooling water circuit for leaks. Remedy any leaks before
continuing with start-up.
