Page 6: General Rules
General rules Range of application This machine may only be used for cleaning facades, vehicles, containers, pavement slabs, stables, machines and smilar objects. Inspections The machine must be inspected according to the “Guidelines for Liquid Spray Devices” at least once every 12 months by a qualified person, to ensure that continued safe operation is guaranteed. -
Page 7: Safety Precautions - Accident Prevention
Safety notes Never operate the machine without supervision. The machine may only be operated by persons who have been instructed accordingly. Some parts inside the machine, all water conducting components and all metal parts of gun and lance are hot during hot water operation. Keep all hoods and protective covers closed during operation and never touch any metal parts of gun or lance. - Page 8 Safety notes - This is prohibited! Never direct the high-pressure water jet towards the operator him-/herself or towards other persons, not even for cleaning clothing or shoes. Never direct the water jet at animals! Only use power cables which are in perfect working order! Do not damage the power cable or repair it incorrectly! Never pull the high pressure hose if it...

Page 9: That's What You Have To Observe
Please note - important! Lack of water Lack of water occurs more often than you probably believe. The more powerful a high-cleaner is the greater is the danger that a lack of water occurs. If there is only an insufficient amount of water available, cavitation arises inside the pump, which is normally noticed too late or even not at all. -
Page 10: Kränzle Technology
Please note - important! Insufficient quantity of electricity If there are too many collectors in your proximity connected to the network at the same time, the available voltage and the current intensity may decline. Consequently the motor of the high-pres- sure cleaner does not start or even blows. -
Page 11: Lance And Spray Gun
Kränzle technology Lance with trigger gun The machine can only be operated when the safety trigger is squeezed. When the lever is squeezed, the spray gun opens. The liquid is then pumped to the nozzle. The spray pressure increases and quickly reaches the selected operating pressure. When the trig- ger is released, the trigger gun closes and any further spraying of liquid from the lance is stopped. -
Page 12: Total Stop System
Kränzle technology Total stop system The machine is fitted with a Total-Stop-System. If the gun is closed for longer than approx. 20 seconds, the machine switches off automatically, after 20 minutes the machine moves to safety switch off and you must use the main switch to turn it back on. The machine restarts automatically when the gun is operated, provided that the master switch is on. -
Page 13: Heat Exchanger
Heat exchanger The water is forced through a heating coil by the high pressure pump. Heating coil: 38 m long - Content: 5 l of water - Heating capacity: max. 90 kW The fuel pump draws the oil from the tank through a filter and pumps it to the injector nozzle. -
Page 14: Commissioning
Commissioning Install holding devices for power cable. Install water inlet filter. Fill fuel tank with fuel. (Light heating oil EL DIN 51 603 or diesel fuel) Max. quantity 25 litres. . Check water inlet filter for cleanliness prior to putting the machine into operation! Unscrew glass body of the inlet filter and check if metal sieve is soiled. - Page 15 Move machine to job site. Kränzle-therm appliances are movable machines with a sturdy chassis. Steering the machine: To change direction tilt machine by pressing a foot against the footrest and pull the handle at the same time. Then turn machine into desired direction.

Page 16: Usage As A Cold Water High Pressure Cleaner
Commissioning Push on HP hose to gun. Screw together HP hose and gun pressure-tightly. Take care that all screw connections are pressure-tight. A leakage of gun, high-pressure hose or hose drum has to be repaired at once. Leakages lead to an increased wear and to a possible malfunction of the delayed motor cut-out. -
Page 17: Usage As A Hot Water High Pressure Cleaner
Usage as a hot water high pressure cleaner Method same as with cold water high-pressure cleaner, then ... Set desired temperature at the thermostat. (Min. temperature 40 °C) Engage fixing brake before starting the cleaning process! Switch on main switch with disen gaged spray gun. -
Page 18: When Using Detergents
Suction of detergents with detergent supply from the suction side: Detergent injection on the pressur side, as you probably know it from other HP cleaners, consume approx. 30 % of the cleaning energy, no matter if they are used or not. Due to the water tank fitted to the Kränzle therm cleaners it is now possible to directly suck the detergent into the pump thus reducing output loss and increasing the efficency considerably The detergents are applied without having to reduce the working pressure. -
Page 19: Decommissioning - Frost Protection
Decommissioning - frost protection 01. Switch off the machine - main switch to „0“- position 02. Cut off the water supply 03. Open the spray gun briefly until the pressure is released 04. Apply the safety catch on the spray gun 05. -
Page 20: Care And Maintenance (Weekly/Yearly)
Care and Maintenance The machine must be disconnected from the power supply when ser- vicing work is being carried out. The main switch should be in position "0" and the plug out of the socket. Weekly, or after approx. 40 hours of operation: Check the oil level of the high pressure pump. -
Page 21: Changing The Oil
Changing the oil: First oil change after approximately 50 operating hours. Thereafter the oil should be changed every 500 operating hours or yearly. Take the oil drainage hose, which is connected to the oil drainage screw from the inside of the appliance. Open the red oil filler plug at the top side of the black oil housing. -
Page 22: Fuel System
Care and Maintenance 5. Hold the gun in a separate container and press the trigger. 6. Wait for about a minute until the decalcifier comes out of the gun (recognisable by its whitish colour) 7. Switch off the machine and allow the solution to act for about 15-20 minutes. 8. -

Troubleshooting Malfunction Cause of malfunction / remedy Water supply Water tank runs over. Float valve is dirty or defect. Water tank does not fill completely. Float valve is defect. Water filter is dirty. Insufficient water inlet quantity. Pump does not suck. Valves stick or are dirty. - Page 27 Troubleshooting Excess temperature release As an additional safety device the appliance is equipped Überhitzung / Overheating Heißwasserbetrieb erst with an excess temperature sensor inside the chimney. Should nach Abkühlung möglich. Hot-water operation only possible the safety devices as e.g. the float monitoring device be defec- after cooling down phase.
- Page 28 Troubleshooting Hot water mode The fuel manometer shows the fuel pressure. If no pressure is shown, check if - there is heating oil in the tank. - the fuse in the electric box (below the operating panel) for the motor has blown. - the fuel sieve or the fuel sieve in the pump is dirty.

Increase burner does not heat. temperature on thermostat with rotary control switch. Open gun, until temperature drops. Fuel tank is empty. Fuel filter is dirty. Fuel nozzle is dirty. Fuel pump/blower does not operate.
- Page 30 Small repairs do it yourself No water from the nozzle but the gauge shows full pressure: Most likely the nozzle is blocked. (Inside the pressure gauge there is no water but a filling with glycerin to damp the vibration of the poin- ter.) Proceeding: Switch off the cleaner.
- Page 31 The pressure gauge shows full pressure although the gun has been closed. The pressure switch valve switches constantly. Possible cause no.1: Leakage Having closed th gun, the HP cleaner must shut down and the pressure gauge must show „0“ bar. If the pressure gauge still shows full pres- sure and the motor constantly switches on and off, the possible reason for this can be a leaka- ge of the pump, the HP hose or the lance.
- Page 32 Small repairs do it yourself Pressure gauge shows little pressure, the water from the nozzle comes in squirts, The high-pressure hose vibrates. Most likely the valves are soiled. Proceeding: Unscrew all 6 valves, one after the other (hexagonal brass screws, 3 in a row, vertically and horizontally) Take out valve body (with green or red plastic coating) and O-ring by means of needle nose...
