Safety features
Overflow valve with two pressure
switches
— When reducing water volume at pump
head or with the servopress control, the
overflow valve will open and part of the
water will flow back to the pump suction
side.
— If the handgun is closed off so that all
the water flows back to the pump suction
side, the pressure switch at the overflow
valve turns off the pump.
— Reopening the handgun causes the
pressure switch at the cylinder head to
switch the pump back on again.
The overflow valve is set at the factory and
lead-sealed. Adjustment can only be made
by After-Sales Service.
Safety valve
— The safety valve opens if the overflow
valve or pressure switch is defective.
The safety valve is set at the factory and
sealed. Adjustment can only be made by
After-Sales Service.
Low water protection
— The low water protection prevents the
burner switching on when water is
insufficient.
— A strainer prevents dirt accumulation on
the protection and must be regularly
cleaned.
Motor protection switch
— The motor protection switch interrupts
the circuit should overloading occur.
Switching on procedures
— Switching on procedures generate brief
voltage drops.
— Impairments of other appliances can
occur in cases of unfavourable mains
conditions.
— No problems are to be expected with a
mains impedance of less than 0,15 ohm.
