General notes

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.
