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 and Menu back simultaneously
for 5 seconds.
• Enter code 1122 by pressing Increase value
or Decrease
value for number, and Menu forwards or Menu back
for location.
• Confirm the code by pressing Start
.
• Select
SAFETY TESTING with Decrease value and press
Menu forwards
.
• Confirm by pressing Start
.
• When the safety valve has been opened (blown ), switch
off the current with Control switch On/Off
.
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.

Warning!
The steam pressure whitch may not
exeed 150 kPa/1,5 bar. If the indicator enters
the Red field:
Stopp the operation.

Control manometer tap
Tap with flange for control manometer.
Application: screw (A) removes and control manometer con-
nects to the flange.
The tap (B) opens completly by using tool.
Warning!
Do Not remove the screw (A) when the
tap (B) is open, warning for hot steamt.
When changing details in above mentioned parts use Loctite
type 542 (red) for installation in the fittings .
The fitttings fits to the vessel by using loctite type 275 (green) .
