Control testing of safety valve
During inspection of pressure vessels, a check is performed
to ensure the safety valve opens at the correct pressure 150
kPa (1.5 bar). In order to check this, the pan´s safety functions
must be disabled (see Fig. 1-2).
To bring the pressure in the pan to above 110 kPa
(1.1 bar), you have to go into a hidden menu in the electronics:
•
Press Menu forwards
for 5 seconds.
•
Enter code 1122 by pressing Increase value
value
for number, and Menu forwards
for location.
Manometer
It measures the steam pressure. Must not exceed 150 kPa
(1.5 bar)
If the indicator goes into the red field:
• Switch off the pan immediately and call in a trained engineer.
* For a correct pressure reading, lift up the green cap on the
manometer.
NOTE! The green cap must normally be pressed down as the
pan will be tipped.
