Directive 97/23/EC for pressure equipment (PED). The compliance with this requirement is assured by
a special electronic device that constantly checks:
• that for temperatures above 110 °C/230 °F, the pressure set is below 32 bar/464 psi;
• that for pressures above 32 bar/464 psi, the temperature set is no greater than 110 °C/230 °F.
If the above limits are exceeded, the burner stops and the warning light (48) comes on.
Steam operation will only resume if the pressure is reduced to below 32 bar/464 psi.
