Safety devices are provided for your own protection. Do not bypass, remove or render ineffective any safety devices. Adjustments are performed only by customer service.

Power switch

The power switch prevents the device from starting up unintentionally. Turn the power switch to 0/OFF during work breaks or when finishing work.

Safety latch

The safety catch on the high-pressure gun prevents the device from being switched on inadvertently.

Overflow valve with pressure switch

When the water quantity is reduced via the pressure/quantity control on the trigger gun, the overflow valve opens and part of the water flows back to the suction side of the pump. When the trigger on the high-pressure gun is released, the pressure switch switches off the high-pressure pump and the high-pressure jet stops. The pump switches on again when the trigger is pulled.

Readiness time

If the device is not used for 30 minutes, the device switches off. The readiness time can be activated and deactivated by customer service via the service menu.

Motor circuit breaker with winding protection contact

The motor circuit breaker shuts off the device if power consumption is too high. The winding protection contact switches the device off in the event of thermal overload.

Leakage monitoring

If there are leaks in the high-pressure system, the device is switched off.

Water shortage safeguard float container

The water shortage safeguard prevents the high-pressure pump from switching on when there is a lack of water.

Pressure relief of high pressure system (option)

After switching off the device via the high-pressure gun, a solenoid valve located in the high-pressure system opens after the operating standby time has elapsed. This reduces the pressure built up in the high-pressure system.

The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.

Note: Installation may only be carried out by authorised specialist personnel!

The water connection, the high-pressure network and the electrical connection may only be carried out by authorised specialist personnel in compliance with local regulations.

• The system should be installed in a dry, non-explosive environment.

• The device should be installed on a firm and level surface.

• The system should be easily accessible for maintenance work.

• The system can be mounted on the wall or with the floor structure attachment kit (optional).

• Check the load capacity of the wall before installation. Use suitable plugs and screws for concrete, cavity block, brick and aerated concrete walls, e.g. an injection anchor.

• The device must not be rigidly connected to the water supply or high-pressure pipework. The connecting hoses must always be fitted.

• Provide a stopcock between the water pipe network and the connecting hose.

• Do not place the system directly against the side of a wall. There are openings on the side of the system for cooling, which must not be blocked.

Note: Switch-on procedures will generate short-term voltage drops. Unfavourable mains conditions may cause other devices to be impaired.

ATTENTION: Exceeding the grid impedance

Electrical shock in the event of a short-circuit. The maximum permissible mains grid impedance at the electrical connection point (see Technical data) must not be exceeded. Contact your electricity supplier in the case of any uncertainties regarding the mains grid impedance at your electrical connection point.

• For connected loads, see technical data and type plate.

• The electrical connection must be carried out by an electrician and comply with IEC 60364-1.

• All live parts, cables and devices in the work area must be in proper condition and be protected against water jets.

DANGER: Danger of death from electric shock.

If the device is operated at a socket without an error current circuit breaker or without a protective contact (earthing), there is a danger of death from electric shock in the event of a fault! Only operate the device at sockets with an earthing contact and with an error current circuit breaker with a nominal fault current of max. 30 mA.

• Design the water inlet for continuous operation.

• Fit the water supply line with a shut-off valve and connect it to the high-pressure unit via a flexible pressure hose.

• If the line cross-section is too small or the inlet pressure is too low, the result is a water shortage.

• If the inlet pressure is too high or there are pressure peaks in the line system, always connect a pressure reducer upstream. A water drain must be available at the installation site.

• If the “Solenoid valve water inlet” attachment kit is installed, the valve blocks the water inlet until the device is switched on.

Observe the relevant national regulations when installing the high-pressure lines.

• The connection between the permanently installed pipework and the device must be a high-pressure hose line.

• Lay the permanently installed pipework as straight as possible. Lay high-pressure pipelines in accordance with regulations, taking into account length changes due to heat and pressure effects, using dampened sliding and fixed clamps.

• In order to minimise pressure losses in the high-pressure lines, the following recommendations should be observed:

Pipelines: Nominal width DN 15

Hose lines: Nominal width DN 8

hose lines HD 17-15 St (H): DN 10

For the above-mentioned guide values, the pipework length and the number of changes of direction and fittings must also be taken into account.

Device with ANTI!Twist: Attach the yellow high-pressure hose connection to the high-pressure gun.

Note: The EASY!Lock system connects components quickly and safely via a single turn of the quick-release thread.

1. Connect the spray lance to the high-pressure gun and hand-tighten (EASY!Lock).

2. Plug the high-pressure nozzle onto the spray lance.
