Checking/refilling the coolant
In the cover on the rear of the device is a recess in
which you can see the coolant level of the supply
tank, and markings for the minimum and maximum
permissible coolant level (see arrows in Fig. 54).
When the water level sinks to the min. level, refill the
tank with deionised water.

2.
Plug in the quick release coupling of the funnel
tube into the corresponding socket (see arrow
(A) in Fig. 56).
3.
Fill in deionized water up to the max. level (see
arrow in Fig. 55).
4.
If the device is filled up for the first time switch
on the main switch so that the pump starts up
and the air is removed from the coolant circuit.
(The water level in the supply tank sinks consi-
derably.) Then fill up again with DI water up to
the maximum level.
5.
Press down the lock (see arrow (B) in the
figure above) and pull out the funnel tube.
WARNING
Avoid any skin or mucous membrane
(nose, eyes, mouth) contact with the
