Steam Boiler Pressure Calibration

Steam boiler pressure is controlled by the pressureswitch. The pressure inside the boiler continues to riseas the water is heated by the heating elements.Reducing pressure will reduce temperature, whileincreasing pressure will increase temperature. Thesteam boiler has been factory adjusted to 1 bar, (therecommended pressure). Check if the pressure on thepressure gauge is 1 bar or in the blue zone (1-1.4 bar)(see Figure P). if so, you don’t need to adjust thepressure. If there is a need to change the pressure,follow below procedure for calibration:

1. Turn off machine.2. Remove top cover of machine, and locate the

pressure switch in the center, back area (see FigureQ).

3. Use slotted screwdriver to adjust the pressure asshown in Figure R. Turn screw clockwise to increasepressure, or counterclockwise to reduce pressure. Acomplete screw turn results in about 0.1 barvariation.
