General Instructions
Operation in Accordance with Regulations
- This high-pressure cleaner must only be used for cleaning with a high-pressure jet or for cleaning with a low-pressure jet with detergent (e.g., with foam injector or wash brush).
- Users must comply with environmental regulations.
- The high-pressure cleaner has undergone a final inspection by Kränzle.
- The high-pressure cleaner should be inspected by a professional for safe operation at least once a year, or as needed, according to the "Guidelines for Fluid Jet Devices." Keep records of these inspections.
- Industrial high-pressure cleaners must be inspected by a professional every 12 months.
- Users must ensure that all safety-relevant parts are in perfect condition before each use.
Accident Prevention
- The high-pressure cleaner is designed to prevent accidents when used by trained personnel. Users should be aware of the hazards associated with hot components and the high-pressure jet. Comply with the "Guidelines for Fluid Jet Devices."
- Combustion requires air and produces exhaust gases. If the high-pressure cleaner is used in enclosed spaces, ensure safe exhaust of combustion gases and adequate ventilation.
- Do not block the exhaust gas opening on top of the high-pressure cleaner. Do not lean over this opening or place your hands in it. The emitted exhaust gases are very hot.
Oil Change
- The first oil change should be performed after approx. 50 operating hours, then annually or after 500 operating hours.
- If the oil turns white or grey, it must be replaced.
- To change the oil: Remove the large right cover and loosen the oil drain screw from the inside. Open the red oil filler cap on top of the silver oil housing and then the cap on the end of the hose. Collect the oil in a container and dispose of it according to regulations. Close the end of the hose. Then add new oil.
- Contact customer service immediately in case of oil leakage. Failure to do so may result in environmental or technical damage.
- Condensation may form with high humidity and fluctuating temperatures. If the oil turns white or grey, it must be replaced.
Descaling
- Limescale in the heat exchanger consumes unnecessary energy as the water heats up slowly. The pressure relief valve returns part of the water to the high-pressure pump.
- Limescale can be identified by higher pipe resistance. To check, disconnect the lance from the spray gun and switch on the high-pressure cleaner. A full water jet should emerge from the spray gun. If the pressure gauge shows more than 50 bar, the high-pressure cleaner must be descaled as soon as possible.
- To descale: Remove the lance and descale it separately. Place the suction hose of the detergent injector into a container with the descaling solution. Set the detergent valve to the highest concentration. Switch on the high-pressure cleaner. Hold the spray gun with safety lock in a separate tank and press the trigger. Wait until the descaling fluid exits the safety spray gun (recognizable by its whitish color). Switch off the high-pressure cleaner and let the descaler work for 15-20 minutes. Switch the high-pressure cleaner back on and flush with clean water for 2 minutes. Check if the pipe resistance has decreased. Repeat descaling if necessary.
- Descaling agents are corrosive! Observe the instructions for use and accident prevention regulations. Wear protective clothing to prevent contact with skin, eyes, or clothing.
Fuel System
- Fuel can contain dirt particles, or dirt and water can enter the fuel tank during refueling. The high-pressure cleaner has a fuel filter to protect the fuel pump. Check this filter regularly for contamination and replace it if necessary.
- Regularly check the fuel tank for contamination. Clean it if necessary. Empty the fuel tank using the drain plug at the bottom. Carefully clean the fuel tank and fuel lines. Tighten the plug again.
- Dispose of cleaning agents and contaminated fuel responsibly.
- Regularly check the fuel system for contamination. No warranty is provided for damage to the fuel system caused by contamination.
- Users must comply with applicable laws and regulations.
Electrical Connection
- The high-pressure cleaner is supplied with a power cable. The power plug must be inserted into a properly installed grounded socket with a 30 mA residual current device. The power connection must be carried out by a qualified electrician and must comply with IEC60364-1.
- The socket must be protected by a 16 A slow-acting fuse (Type C, K).
- When using an extension cord, it must have a ground connection connected according to the regulations for the plug connections. The cables must have a cross-section of at least 2.5 mm². Connections must be splash-proof and not lie on a wet floor. When using a cable reel, the power cable must always be completely unwound.
Water and Cleaning System
- Water can be supplied to the high-pressure cleaner under pressure. A float valve in the water reservoir regulates the water supply. The water is then drawn by the high-pressure pump from the water reservoir and guided under pressure into the safety spray tube. The spray nozzle on the safety spray tube then forms the high-pressure jet. By bypassing the water reservoir, water can also be drawn directly from a pressureless reservoir (see Direct Suction).
- Users must comply with environmental regulations.
Safety Spray Tube with Spray Gun with Safety Lock
- The spray gun with safety lock only works when the lever of the spray gun with safety lock is pressed. Operating the lever opens the spray gun with safety lock. The fluid then flows to the nozzle. Pressure builds up and quickly reaches operating pressure. When the lever is released, the spray gun with safety lock closes, and no fluid exits the safety spray tube. The pressure surge when closing the spray gun with safety lock opens the pressure regulating valve (also safety valve). The motor is switched off by the pressure switch. Opening the spray gun with safety lock closes the pressure regulating valve/safety valve, and the motor restarts, and the high-pressure pump transports water to the safety spray tube at the set pressure.
- The spray gun with safety lock is a safety component. Repairs must only be carried out by qualified personnel. Only use parts approved by the manufacturer when replacing parts.
Pressure Regulating Valve / Safety Valve
- The pressure regulating valve / safety valve protects the high-pressure cleaner against inadmissible overpressure and is designed so that it cannot be set higher than the permissible operating pressure. The adjusting screw is sealed with lacquer. Pressure and flow rate can be adjusted infinitely using the rotary knob.
- Replacement, repairs, adjustments, and sealing must only be carried out by qualified personnel. The high-pressure cleaner must not be connected to the power supply during these operations, i.e., the plug must be removed from the socket.
Motor Safety Switch
- The motor is protected against overload by a motor safety switch. The high-pressure cleaner switches off in case of overload or motor blockage. Eliminate the cause of the fault if the motor switches off repeatedly.
- Replacement and maintenance work may only be carried out by qualified personnel. The high-pressure cleaner must not be connected to the power supply, i.e., the plug must be removed from the socket.
Totalstop System with Delayed Motor Shutdown
- When the spray gun with safety lock is opened, the motor is started via a Totalstop system. When the spray gun with safety lock is closed, the motor switches off after 38 seconds, and the unit enters standby mode. The delayed shutdown is necessary because frequent starting and stopping of the motor in high-pressure cleaners can lead to strong loads on the power grid and increased wear of the switching elements. After 20 minutes in standby, the unit disconnects from the power supply and must be switched on again using the main switch. If the spray gun is opened again, the unit starts automatically as long as the main switch is on.
Starting Up
Safety Lock
- If the high-pressure cleaner is accidentally not switched off after use, or if the spray gun with safety lock is not operated for 20 minutes, the high-pressure cleaner automatically enters the safety status by deactivating. It can be reactivated by operating the main switch.
High-Pressure Hose and Spray Device
- The high-pressure hose and spray device included as accessories for the therm 1017/therm 1017 T are made of high-quality material and are marked according to regulations.
- Only use parts approved by the manufacturer. Using non-original parts voids the warranty! High-pressure hoses and spray devices must be connected tightly (no leaks).
- Do not drive over the high-pressure line, do not pull the line too far, and avoid twisting. Do not pull the high-pressure hose over sharp edges. Defective high-pressure hoses must not be repaired (according to DIN 20022) but must be replaced with new high-pressure hoses approved by the manufacturer.
- Ensure all safety regulations are followed before starting up.
Starting the Unit
- Mount the power cable holders with the screws.
- Mount the water inlet filter (optional) to the water inlet.
- Fill the fuel tank with heating oil before commissioning. Heating oil (EL DIN 51 603) or diesel (DIN EN 590). Filling capacity 25 liters.
- To move the high-pressure cleaner to the place of use, release the brake.
- The therm 1017/therm 1017 T is a portable high-pressure cleaner with robust running gear for outdoor use. To steer the high-pressure cleaner, press the tilting bracket with your foot and pull the high-pressure cleaner towards you.
- For high-pressure cleaners with a hose reel, unlock the reel and fully unwind the high-pressure hose. For high-pressure cleaners without a hose reel, firmly screw the included high-pressure hose to the pump outlet. Roll out the high-pressure hose straight and without kinks. The high-pressure hose may leave marks on some floors. Alternatively, non-marking high-pressure hoses are available.
- Connect the grey rotating screw connection of the high-pressure hose to the safety spray gun. Then screw them together tightly and pressure-proof.
- First, pull back the protective sleeve of the spray gun with safety lock, then insert the lance into the quick-connect coupling of the spray gun with safety lock.
- After inserting the lance, release the protective sleeve and observe the safe position of the lance. Regularly lubricate the quick-connect nipple with acid-free grease.
- During operation, the quick-connect coupling must not be operated/touched! High risk of injury!
- Check the quick-connect coupling and nipple for cleanliness (sand, dirt, ...) before inserting, if necessary clean with clean water. Contamination can damage the seal in the quick-connect coupling.
- Pay attention to the maximum length of 20 m when extending the high-pressure hose!
- Accessories may only be connected to a Kränzle-approved safety spray gun.
- Before each use, check the water inlet sieve for cleanliness. Unscrew the filter cup manually, remove the water inlet sieve, and rinse and clean it with clean water along with the other parts. If the sieve is dirty, no water can pass through, and pressure cannot build up. Check the water inlet sieve for damage. Do not operate the high-pressure cleaner without or with a damaged filter.
- Connect the water hose to the water inlet (minimum requirements: 5 m hose length, 3/4" diameter, 10 bar). The unit can optionally be connected to a pressurized water supply (1-10 bar water pressure) with cold or warm water up to 60 °C. The therm 1017/therm 1017 T can draw water from a reservoir (see direct suction).
- Caution with warm supply water! When operating with 60 °C warm inlet water, increased temperatures occur. Do not touch metal parts on the high-pressure cleaner without safety gloves!
Operation as a Cold-Water High-Pressure Cleaner
- Set the temperature on the thermostat to "0".
- The detergent valve must be closed.
- Switch on the high-pressure cleaner with the spray gun with safety lock open. Vent the high-pressure cleaner: Open and close the spray gun with safety lock several times. Start cleaning.
- Do not aim the high-pressure jet at the object being washed for at least 30 seconds at the beginning of the washing cycle. The water content of the combustion chamber may be discolored due to the standstill period.
Operation as a Warm-Water High-Pressure Cleaner
- The detergent valve must be closed.
- Set the desired temperature on the thermostat (minimum temperature 40 °C). The high-pressure cleaner operates at the most economical temperature in the eco-phase.
- Switch on the high-pressure cleaner with the spray gun with safety lock open. Vent the high-pressure cleaner: Open and close the spray gun with safety lock several times.
- Switch on the heating. The water is heated and kept at the set temperature.
Direct Water Suction
- Thanks to the suction power of the high-pressure pump (up to 2.5 m suction height, max. hose length 3 m), the high-pressure cleaner can also draw cleaning water from separate reservoirs or streams. In this case, the water reservoir must be bypassed.
- Disconnect the connecting hose between the high-pressure pump and the water reservoir.
- Screw the hose with suction filter (Art. No.: 150383) to the connecting hose using a double nipple (Art. No.: 46004).
- Place the water-filled suction hose into the water-filled preferred reservoir and start cleaning. Pay attention to clean water! Do not suck in chlorinated water! Do not suck in air!
- For the first suction, the high-pressure pump or the suction hose must be filled with water.
Note
- Depending on water quality, valves may stick after prolonged standstill. Consequently, the high-pressure cleaner may not draw water from a reservoir correctly. In this case, connect a water hose with pressurized water to the pump inlet. After starting the high-pressure cleaner, the pressurized water will open the valves, and you can then work from a reservoir as usual.
Using Additives
Suction of Additives
- Due to the presence of the water reservoir in the therm 1017/therm 1017 T, it is now possible to draw additives directly into the high-pressure pump, which prevents a reduction in performance and leads to an increase in efficiency.
- Place the detergent injector hose into the reservoir with the additive.
- Dose the additive by turning the detergent valve. Closing the detergent valve stops the supply of additive.
- After using additives, flush the high-pressure cleaner with clean water with the safety spray gun open.
- Only open the detergent valve when the chemical sieve is immersed in the liquid! Sucked-in air causes damage to the pump seals (No warranty!).
- The additive must have a neutral pH value of 7-9. This machine was developed for use with detergents supplied or recommended by the manufacturer. The use of other detergents or chemicals can affect the safety of the machine. Follow regulations, e.g., protective equipment, wastewater regulations, etc.
- Caution Solvent! Never suck in liquids containing solvents, such as paint thinner, gasoline, oil, or similar! The seals in the high-pressure cleaner are not resistant to solvents! Furthermore, the spray mist from solvents is highly flammable, explosive, and toxic.
Putting Out of Operation
Shutting Down
- Switch off the high-pressure cleaner.
- Turn off the water supply.
- Open the spray gun with safety lock until the pressure is released.
- Lock the spray gun with safety lock.
- Disconnect the high-pressure hose and the spray gun with safety lock.
- Empty the high-pressure pump: Hold the high-pressure hose and switch on the motor until no water jet emerges from the outlet.
- Unplug the power cord from the socket.
- Clean the high-pressure hose and roll it up neatly. Secure the hose reel.
- Clean the power cable and wind it up.
- Clean the water inlet sieve.
- Apply the parking brake.
- Store the high-pressure cleaner in a frost-free room during winter.
Frost Protection
- To protect the high-pressure cleaner against frost, drain it completely. To do this, disconnect the high-pressure cleaner from the water supply and switch it on. By opening the safety spray gun, the water is expelled from the water tank. Do not run the high-pressure cleaner without water for longer than one minute. Add antifreeze to the water tank and switch on the appliance. With the spray gun open, wait until the agent comes out of the nozzle.

Small Repairs – DIY
Problem: No water from the nozzle, but the high-pressure pump is running. The stainless steel pressure gauge shows full pressure.
Cause: The nozzle is likely clogged.
The stainless steel pressure gauge shows full pressure. Little or no water comes out of the lance.
Procedure:
- Switch off the high-pressure cleaner.
- Unplug the power cord from the socket.
- Briefly press the spray gun with safety lock to release the pressure.
- Remove the spray gun with safety lock and the lance, and remove any residue from the high-pressure hose. Check the water inlet sieve for contamination.
- If the problem persists, carefully push a wire (paperclip) through the nozzle opening. If cleaning with a wire does not yield the desired result, the lance must be replaced.
- For any repair, unplug the power cord from the socket!
Problem: Irregular spray jet from the nozzle. The stainless steel pressure gauge shows low pressure.
Cause: The valves may be dirty or clogged.
Despite the pressure regulator being turned up, the pressure gauge shows low pressure, the lance emits an irregular jet, and the high-pressure hose vibrates.
Procedure:
- Unscrew all 6 valves (arranged vertically and horizontally in a row of 3 brass socket screws).
- Remove the valve body (with green or red plastic housing) and O-ring with sharp pliers. Check the sealing ring for damage. If damaged, replace the O-ring.
- Clean the valves with a wire (paperclip) and, if possible, under running water.
- Do not forget the sealing ring when reinserting!
Problem: After closing the spray gun with safety lock, the high-pressure cleaner constantly switches on and off. The stainless steel pressure gauge still shows full pressure.
Possible Cause No. 1: Leak.
After closing the spray gun with safety lock, the high-pressure cleaner should switch off. The stainless steel pressure gauge should indicate the permitted switch-off pressure (see type plate). If switching off does not occur and the stainless steel pressure gauge still indicates full pressure (unit does not bypass), a leak in the high-pressure pump, pressure switch, high-pressure hose, or spray gun with safety lock could be the cause.
Procedure:
- Check the connections of the high-pressure cleaner to the high-pressure hose, the high-pressure hose to the spray gun, and the lance to the spray gun with safety lock for any leaks.
- Switch off the high-pressure cleaner. Briefly activate the spray gun with safety lock to reduce pressure. Remove the high-pressure hose, the spray gun with safety lock, and the lance, and check the sealing rings. If the sealing rings are defective, the O-rings must be replaced immediately.
- No warranty is provided for consequential damage caused by leaks.
Problem: After closing the spray gun with safety lock, the high-pressure cleaner constantly switches on and off. The stainless steel pressure gauge still shows full pressure.
Possible Cause No. 2: The check valve is defective.
Procedure:
- Switch off the high-pressure cleaner, unplug the power cord from the socket. Turn off the water supply.
- Briefly press the spray gun with safety lock to release the pressure. Unscrew the pump outlet.
- Remove the check valve pin and check the O-ring for contamination or damage. Also check the stainless steel sealing seat in the pump housing for contamination or damage.
- If the sealing rings are defective, the O-rings must be replaced immediately.
- No warranty is provided for damage to the high-pressure pump due to defective sealing rings resulting from air suction or lack of water (cavitation).
