Connection
- 01Check the condition of the pressure washer, power cord, plug with switch and accessories. Check that the inlet filter and nozzle are clear, and check the mountings and connections.
- 02With the power supply disconnected, after the device has cooled and the pressure has dissipated on its own, unscrew the attachment from the spray gun.
- 03Place the inlet hose with the inlet filter in a container of clean water. The inlet filter must be below the water surface.
- 04Connect the pressure washer to an earthed socket with a power supply matching the rating plate. Set the switch on the plug to ON. When the LCD lights up and you hear a voice message, the pressure washer is ready for use.
Priming
Fill the system with water before cleaning to prevent it from running dry.
- 01Point the spray gun without an attachment into a container, select COOL mode and press START/STOP. Wait until the water flows in a steady stream.
- 02Stop operation using START/STOP.
How to use
Selecting and changing the attachment
| Mode | Attachment |
|---|---|
| STEAM | Universal nozzle or long steam nozzle with a Ø2 mm opening. |
| COOL / HOT | 0°, 15° or 25° water nozzle or 290° rotating nozzle. |
| PULSE | Rotating nozzle for water operation. |
Do not use water nozzles in STEAM mode. Use the bent nozzle and extensions in hard-to-reach places.
HOT and STEAM modes operate with factory settings. The H / M / L pressure can only be adjusted in COOL mode.
Cleaning with water or steam
- 01Prepare the pressure washer as described in the ‘CONNECTION’ section.
- 02Disconnect the power supply and, once the device has cooled and the pressure has dissipated, fit the attachment selected for the mode. Then reconnect the power supply and set the switch on the plug to ON.
- 03In the STOP state, select the mode on the panel or using the spray gun FUNCTION button. Point the nozzle into a container and start operation using START/STOP.
- 04In COOL mode, select the pressure using the adjustment button on the panel or the spray gun FUNCTION button: L - 10 bar, M - 20 bar, H - 30 bar. Monitor the current parameters on the display.
- 05In COOL and HOT modes, turn the rotating nozzle left or right to set the direction of the jet.
- 06In STEAM mode, wait approximately 25–30 s for steam to be prepared. Pressurised water flows from the nozzle for approximately 1 s. Keep the nozzle over a container during this time.
- 07Point the nozzle at the surface to be cleaned and start cleaning.
Finishing work
- 01Stop operation using START/STOP. After operation in HOT or STEAM mode, disconnect the power supply, wait for the device to cool and the pressure to dissipate on its own, then remove the steam nozzle if fitted.
- 02Make sure the inlet hose with the inlet filter is submerged in clean water. Connect the power supply and set the switch on the plug to ON.
- 03Point the spray gun into a container, select COOL mode and run clean water through the system for approximately 10 s to flush and cool it.
- 04Stop operation using START/STOP and disconnect the power supply.
- 05Remove the inlet hose from the container. Clean the accessories and inlet filter; leave the pressure washer to dry before storage.
Ozone disinfection - DISINFECT
- 01Leave the air conditioner being cleaned disconnected from the power supply. Place the separate black ozone disinfection hose inside the unit and seal it, for example with an AC cleaning cover.
- 02Connect the pressure washer to the power supply and set the switch on the plug to ON. In the STOP state, select DISINFECT mode and press START/STOP. Leave the device running for approximately 30 min.
- 03Stop the function using START/STOP and disconnect the power supply. Ventilate the room thoroughly.
Maintenance
General recommendations
If the steam is weak, check that the nozzle opening is clear. Remove white deposits that build up during use by descaling. Calcium and magnesium deposits reduce device performance and can trigger the HIGH TEMP alarm. Descale the device every 3–5 uses.
Cleaning and inspection
- 01With the power supply disconnected, after the device has cooled and the pressure has dissipated on its own, remove the inlet filter from the inlet hose, inspect its mesh and the spray gun attachment, and remove any dirt. Clean the accessible nozzle openings and ventilation openings. Do not damage the mesh or nozzle opening.
- 02Check the condition of the hoses, connections and nozzles. Remove dirt from accessible surfaces. Replace worn nozzles as described in ‘Selecting and changing the attachment’. Have damaged hoses and connections replaced by the service team - submit a service request at wipcool.pl/serwis.
- 03Clean the housing with a soft brush or cloth, without using water. Do not use alcohol, petrol, solvents, corrosive substances or strong detergents. Do not allow housing cleaning agents to enter the pressure washer.
- 04Fit the inlet filter and the remaining components. Check their condition and the power cord, then test in COOL mode with clean water as described in the ‘CONNECTION’ section.
Descaling the device
- 01With the power supply disconnected, prepare a container with a capacity of 3–5 l. Measure out 250 ml of Wipcool Steam Descaler and 1.75 l of water.
- 02After the device has cooled and the pressure has dissipated, unscrew the attachment from the spray gun. Immerse the inlet hose with the inlet filter in the solution and direct the outlet without an attachment into the same container.
- 03After connecting the power supply, set the switch on the plug to ON, select COOL mode and press START/STOP. Circulate the solution for 15–25 min without heating.
- 04Stop operation and replace the solution with clean water.
- 05Restart COOL mode and flush with clean water for 2–5 min without heating.
- 06Stop operation using START/STOP and disconnect the power supply.

Waste electrical and electronic equipment
- 01
The crossed-out wheeled bin symbol means that the end-of-life device must not be disposed of with other waste.
Under the applicable regulations on waste electrical and electronic equipment, products marked with the separate collection symbol must not be disposed of with other municipal waste. Due to their hazardous substance content, electronic products that are not collected separately may pose a risk to the environment and human health. Proper separate collection of waste electrical and electronic equipment prevents adverse effects on the environment.
By taking end-of-life equipment to a collection point, the user contributes to its reuse, recycling and recovery.
Recycling - a method of protecting the environment. The process of recovering substances from waste that can be reused as raw materials.
Waste recovery - the use of waste that has lost its value in use, such as plastics, paper and cardboard, as secondary raw materials (colloquially, also the destruction of waste).
Information on the collection system for waste electrical and electronic equipment
- ■Waste electrical and electronic equipment must not be disposed of with other waste.
- ■The collection of incomplete electrical and electronic equipment and parts from waste equipment is prohibited.
- ■A distributor delivering equipment intended for households to a purchaser must collect waste equipment from households free of charge at the delivery location, provided that the waste equipment is of the same type and performs the same function as the equipment delivered.
- ■The user may hand over waste equipment to a waste equipment collector, a treatment facility or a municipal waste collector in the municipality.
- ■Information on collection points is available on the BIP websites of regional, city and municipal authorities.
