TO ADJUST PRESSURE SWITCH:
1. To obtain access to the pressure switch, the front panel must be removed. Remove the
screws on either side of the panel. Be sure to support the panel to avoid excessive
strain on the wiring.
2. To increase the pressure setting turn the white ribbed knob clockwise; to decrease the
pressure, turn it counterclockwise. Use the centre of the black ring as an indicator.
3. With the kettle empty and completely cold, bypass the thermostat by moving the single
terminal side wire to the double terminal side connector on the thermostat. Turn kettle
on.
4. Pressure in kettle (read pressure gauge on front panel) should reach a maximum of 35
psi and pressure relief valve should not open. Kettle pressure may rise 3 or 4 psi even
after burners shut down.
5. Relief valve should not open when kettle pressure is 40 psi; pressure switch setting is
satisfactory.
6. If relief valve opens, reduce setting on pressure switch, cool kettle completely by
running cold water through it and repeat steps 3 - 6.
7. If pressure in kettle is below 30 psi when burners shut off, increase setting of pressure
switch, cool kettle completely by running cold water through it and repeat steps 3 - 7.
8. When adjustment is complete, move wire from shorted terminal on the thermostat back
to the appropriate terminal and replace the front panel.
