Page 8: Safety Notes
Safety notes User operating the high-pressure cleaner should wear the necessary protective clothing, i.e. waterproof clothing, rubber boots, safety goggles, ear protection headwear etc. It is prohibited to use the high-pressure cleaner in close vicinity to people lacking suitable protective clothing. If noise exceeds the maximum allowed levels, users and others in the vicinity must wear suitable ear protection. - Page 9 Safety notes - This is prohibited! Replacement of the power supply cables is only permitted by use of an original power supply cable of the manufacturer and must be performed by a qualified electrician. Safety devices serve to protect the user and must never be de-activated or their function bypassed.
- Page 10 Safety notes - This is prohibited! Never allow children or untrained persons to use the high-pressure cleaner or to play with it! Children must be kept under supervision to prevent them from playing with the equipment. Never direct the high-pressure jet at the high- pressure cleaner itself! The high-pressure cleaner may not be placed within reach of the high- pressure jet spray mist!
- Page 11 Safety notes - This is prohibited! Apply the safety catch on the safety trigger gun after each use in order to prevent unintentional spraying! Never direct the high-pressure jet at people or animals! Never direct the high-pressure jet at yourself or other persons, not even to clean clothing or shoes.

Page 20: General Rules
General rules Intended use This high-pressure cleaner is to be used solely for high-pressure water jet cleaning applications without detergents or low-pressure cleaning work with detergents (e.g. with a foam injector or washing brush). Environmental, refuse disposal and water protection regulations must be observed! Inspections The high-pressure cleaner was finally inspected by the company Kränzle... -
Page 21: Oil Change
General rules Oil change The first oil change should be carried out after approximately 50 operating hours, then every year or after 500 operating hours. If the oil turns grey or white, you must change the oil. Remove the large right-hand hood of the high-pressure cleaner. - Page 22 General rules Decalcifying Calcified heat exchanger 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 high-pressure pump circuit. The calcified heat exchanger is known by the increased pipeline resistance. Check pipeline resistance by disconnecting the lance from the trigger gun with safety catch and switching the high-pressure cleaner on.
-
Page 23: Fuel System
General rules Fuel System Your fuel may contain particles of dirt, or impurities or water may get into the tank during refuelling. To protect the fuel pump the high-pressure cleaner is equipped with a fuel filter. Check it regularly for dirt and exchange if applicable. Check the tank for impurities on a regular basis. -
Page 24: Functional Details
Functional details Thermostat The thermostat controls the spray water tempera- ture. After you switch on the device, "888" appears in both displays for approx. 1 second as a test of the functioning of the displays. The thermostat also monitors the minimum fuel level in the tank ... -
Page 25: Operating Hour Meter
Functional details This means that the temperature increases far above the desired value or falls far below the desired value. The innovative new percent mode now lets the user specify the switching duration of the heater in percent using the "+" and "-" but- tons (Pos. -
Page 26: Adjusting Ignition Electrodes
Functional details Adjusting ignition electrodes For a smooth ignition, the setting of the ignition electrode must be controlled regularly. Excess temperature sensor As an additional safety device the high-pres- sure cleaner is equipped with an excess tem- perature sensor inside the chimney. Should the safety devices as e.g. -
Page 27: Heat Exchanger
Functional details Heat exchanger The water is forced through a heating coil by the high-pressure pump. The fuel pump sucks the fuel oil from the fuel tank via a fuel filter an and trans- ports it to the injection nozzle. The heat exchanger is heated by a high-pressure fan heater. -
Page 28: Water Supply
Functional details Please note: Lack of water Lack of water occurs more often than you probably believe. The more powerful a high- pressure cleaner is the greater is the danger that a lack of water occurs. If there is only an insufficient amount of water available, cavitation (water-gas mixture) arises inside the high-pressure pump, which is normally... -
Page 29: Electrical Connection
Functional details 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-pressure cleaner does not start or even blows. -
Page 30: Water And Cleaning System
Functional details Water and cleaning system Water can be connected at mains pressure to the high-pressure pump. A float valve in the water tank regulates the water inlet. Then, the water is sucked by the high-pressure pump from the water tank and supplied to the lance under pressure. -
Page 31: Pressure Control Valve/Safety Valve
Functional details Pressure control valve/safety valve The pressure control valve/safety valve protects the high-pressure cleaner from a build up of excess pressure, and is designed not to permit an excess pressure to be selected for operation. The limit nut on the handle is sealed with a spray coating. -
Page 32: Safety Shutdown
Functional details Safety shutdown If the high-pressure cleaner is accidentally not turned off after use or the trigger gun with safety catch is not used for 20 minutes, the high-pressure cleaner auto- matically changes into safety state by deactivation. By operating the main switch once more, the device is activated again. -
Page 33: Putting Into Operation
Putting into operation Install the water inlet filter at the water inlet. Prior to putting into operation fill fuel oil into the fuel tank. (fuel oil EL DIN 51 603 or diesel fuel DIN EN 590). Filling quantity 25 liters. For moving the high-pressure cleaner to the place of use, please release locking break. - Page 34 Alternatively, please also find non-marking high-pressure hoses in our range. therm-RP 900 AT Mount the grey rotating screw connec- tion of the high-pressure hose onto the trigger gun incorporating a safety catch. Afterwards screw together ensuring a snug and pressure-tight fit.
- Page 35 Putting into operation The plug coupling must not be actuated/handled during operation! High risk of injury! Prior to insertion, check plug coupling connection of lance for cleanliness (sand, dirt ..) and use clear water to clean, if necessary. Impurities may damage the sealing in the plug coupling. The high-pressure hose may be extended up to a maximum total length of 40 m.
- Page 36 Putting into operation 11. For getting access to the interior fitting of the high-pressure cleaner, loosen screws at the cover. Remove cap carefully. Close cap properly prior to starting the washing procedure. 12. Each time check oil level at the oil dipstick prior to putting the high- pressure cleaner into operation.
- Page 37 Putting into operation Usage as a cold water high-pressure cleaner Detergent valve must be closed. Switch on high-pressure cleaner with opened trigger gun (trigger pulled). Bleeding of the high-pressure cleaner: Pull and release trigger of trigger gun with safety catch several times. Start with cleaning process.
- Page 38 Putting into operation Usage as a hot water high-pressure cleaner Detergent valve must be closed. Switch on high-pressure cleaner with opened trigger gun (trigger pulled). Bleeding of the high-pressure cleaner: Pull and release trigger of trigger gun with safety catch several times. Set desired temperature at the thermostat.
