Water System - Kranzle therm 890 Operating Manual

Water system

The water flows into a tank.
A float valve regulates the water intake.
The water is then directed to the safety spray pipe
under pressure from the high pressure pump.
The high pressure spray is formed through the nozzle
on the spray pipe.
Detergent and caring system
The high pressure pump can also suck a detergent/caring agent and mix it with the
high pressure jet. - The detergent must have the ph-value 7-9 neutral.
Only open the dosing valve, if the chemistry sieve is placed in a
liquid.
The rules concerning the environment, refuse and ground water
protection must be complied with!
Pressure control and safety facilities
The pressure control valve allows full adjustment of the
quantity and pressure of the water.
The safety valve protects the machine from excessive
pressure and cannot be adjusted beyond the admissible
operating pressure. The setting nuts are sealed with
lacquer.
You find the unlocking button for the excess
temperature release on the console fixed to the
combustion chamber below the ignition transformer.
The machine has to rest for approx. 15 minutes before
it is allowed to press the unlocking button. If the
excess temperature sensor switches the machine off
repeatedly please call the technical service.
Replacements, repairs, new adjustments and sealing operations
may only be performed by trained personnel.

combustion chamber a temperature sensor is installed in
the chimney. This sensor switches off the burner motor,
the ignition transformer and the solenoid valve as soon as
the exhaust gas temperature exceeds 250° C.
