Control testing of safety valve
During inspection of pressure vessels, a check is per-
formed 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.
SM, SV, SP, V, V-C, P, P-C, T, T-C(see Fig. 1)
To bring the pressure in the pan to above 110 kPa
(1.1 bar), you have to go into a hidden menu in the elec-
tronics:
Press Menu forwards
•
taneously for 5 seconds.
Enter code 1122 by pressing Increase value
•
Decrease value for number, and Menu forwards
or Menu back
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 engi-
neer.
* 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.
