  • Page 4: Water System

    Description 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.

  • Page 5: Motor Protection Switch

    Description Motor protection switch The pump motor is protected from overload by a motor protecting switch. In case of an overload the motor is switched off by the motor protecting switch. In case the blue button is not set to „automatic resetting“, it has to be pushed in again by hand.
  • Page 6 Safety Information Brake The Kränzle therm is fitted with a brake that prevents the machine from rolling away on flat ground. Always apply the brakes firmly when working with the machine !!! Brake not applied Brake applied If you want to move the Now you can move the cleaner high pressure cleaner...

  • Page 7: Heat Exchanger

    Description Heat exchanger Heating coil: 34 m long - Content: 5 l of water – Heating capacity: 70 k W The heat exchanger is heated by a high pressure fan heater. A ventilator (1) draws in the cold, fresh air from the bottom end of the machine and forces it upwards between the outer mantle (2) and the inner mantle (3).

  • Page 8: Safety Information

    Safety Information Safety Information Important!!! The machine must be disconnected from the power supply when servicing work is being carried out. The master switch should be in position "0" and the plug out of the socket. Do not use the cleaner if electrical connections or other safety- relevant parts (e.g.
  • Page 9 Safety Information The machine may not be set up and used in rooms where there is a danger of fire or explosion. The machine may not be used under water. Air is required for combustion, and exhaust fumes are generated. If the machine is used in closed rooms, make sure that the exhaust fumes can escape and that there is adequate ventilation.
  • Page 10 This is prohibited! Never direct the water jet at people or animals! Do not damage the power cable or repair it incorrectly! Never pull the high pressure hose if it has formed kinks or “nooses”! Never pull the hose over sharp edges!
  • Page 11 This is prohibited! Never allow children to use the high pressure cleaner! Never direct the water jet at the machine itself! Never direct the water jet at a power socket!

  • Page 12: Electrical Connection

    Commissioning Electrical connection The voltage given on the specification plate must match the mains voltage. The machine is supplied with a power cable and plug. The plug must be connected to a properly installed electrical socket with earthing and have a 30 mA FI residual current circuit breaker. The socket must have a neutral 16A fuse on the mains side.

  • Page 13: Water Connection

    Commissioning Commissioning Secure the machine by applying the brake. Open the right cover of the machine (without chimney) and check the oil level of the high pressure pump. Do not start the machine if there is no oil on the dipstick.

  • Page 14: Usage As A Cold Water High Pressure Cleaner

    Commissioning Electrical connection - Check that the master switch (1) is off (position "0"). Connect the power cable to a properly Hauptschalter Hauptschalter installed electrical socket with earthing Pr es sur e and a 30 mA FI fault current safety b ar b ar 2 50...

  • Page 15: Adjusting The Pressure

    Decommissioning Usage with detergents - The detergent must have the ph-value 7-9 neutral. - Wait until the pump has pressed the air out of the lines - Put the chemical filter into a container with detergent - Open the detergent valve. The pump now draws detergent in and mixes it with the high pressure spray.

  • Page 16: Care And Maintenance

    Care and Maintenance Anti-Freeze Protection The machine is normally still partially filled with water after work has been completed. It is therefore necessary to take special precautions to protect the machine from frost. - Completely empty the machine of water. Disconnect the machine from the water supply and switch off the ignition.
  • Page 17 Care and Maintenance Changing the oil To do this, take the oil drainage hose (1) connected to the oil drain screw, from the inside of the machine and open the red oil filler cap on the top side of the black oil reservoir. Open the cap at the end of the hose.

  • Page 18: Decalcifying The Heating Coil

    Care and Maintenance Decalcifying the heating coil Calcified machines use an unnecessary amount of energy because the water can only be heated slowly and the excess pressure valve feeds a part of the water back into the pump circuit. Calcified machines can be recognised by increased pipeline resistance. Check pipeline resistance by disconnecting the high pressure lance from the gun and switching the machine on.
  • Page 19 Care and Maintenance Rules, directives, inspections Inspections performed by Kränzle - measurement of earth line resistance - measurement of voltage and current - inspection of tension consistency with +/- 1530 V - pressure check of heating element at 300 bar - visual and functional check as per the inspection sheet provided - exhaust fume analysis (see test strips provided) Guidelines for liquid sprayers...

  • Page 21 Description of function - Troubleshooting Cold water mode 1. Connect to water supply and determine whether the water tank fills up completely and the float valve stops. 2. Ignition (switch 1A) to OFF. 3. Main switch to ON. 4. Open high pressure gun. The pump sucks water from the water tank and moves the water through the heating coil to the lance, the pressure is increased.
  • Page 22 Description of function - Troubleshooting The thermostat with rotary switch is controlled by a thermosensor, mounted to the outlet of the heating coil. In the electro distributor box (11) mounted to the combustion unit, there is a fuse, which protects the motor (9) for the fuel pump and ventilator. If the motor is overloaded, the fuse blows.
