8.1.2
Refilling of vaporizer liquid
During operation of the unit, the vaporizer liquid is consumed. It
may be necessary to refill the vaporizer liquid.
When the level of the liquid in the vaporizer glass has gone
down to the sintered gas distributor (
see illustration 5.1.3.F
)
refill vaporizer liquid.
The filling level of the vaporizer liquid can only be checked with
switched-on unit and built-up operating pressure.
After the unit has been switched off, there is a negative
pressure in the electrolyte reactor. This may lead to the suction
of vaporizer liquid into the compensation tank in the vaporizer
glass (
illustration 8.1.3.G
.). After switch-on and build-up of the
operating pressure the vaporizer liquid that has been sucked
into the compensation tank is pressed back into the vaporizer
glass.
Carefully read and observe the safety instructions before
you carry out this maintenance work!
1. Extinguish the burner flame at the burner hand piece.
2. Switch off the gas production at the
on/off
key
I/O
at the
operating panel.
3. Open the closing cap of the vaporizer glass (
see illustration
5.4.A
.).
4. Put the funnel (delivered with the unit) onto the filling
opening of the vaporizer glass (the funnel must be clean).
5. Carefully fill vaporizer liquid not higher than up to the red
filling level marking on the vaporizer glass (
see illustration
5.4.B
6. Screw the closing cap back on the filling opening and
tighten it.
7. Now the filling process is finished.
After prolonged idle periods of the unit, the filling level of the
vaporizer glass can only be determined exactly after the unit
has been operated with correct operating pressure for a short
period of time.
Ensure that the filling level of the vaporizer liquid in the
vaporizer glass does exceed the level marked on the glass.
