3.2.8 Flow switch
The flow switch protects water heater, high-pressure hose, and spray gun against inadmis-
sible heating temperatures. When the flow rate is insufficient, the flow control valve will shut
down the oil burner.

The safety valve protects the machine from excessive pressures.
In our works, the safety valve has been set to the required triggering pressure. The setting
screw is fixed by a locknut and paint-sealed.
The safety valve setting must not be modified. Replacements and repairs may be
carried out by qualified personnel only. In case of replacement, only parts author-
ized by the manufacturer may be used.

By operating the turning knob on the regulating thermostat, the desired operating tempera-
ture can be set.
