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.
