Filling with operating materials 1 Softening salt 2 Detergent Providing the detergent ATTENTION Risk of damage If the detergent tank is empty, the high-pressure pump sucks air and can get damaged. Check the filling level of the detergent containers regu- larly. ATTENTION Unsuitable detergents can damage the system and the object to be cleaned. Use only detergents approved by KÄRCHER. Observe the dosage recommendations and instructions provided with the detergent. Use detergents sparingly to help conserve the environment. DANGER Incorrect handling of detergents can endanger your health. Read and observe the safety and usage instructions provided with the detergent before using the detergent. Wear the protective clothing specified in these docu- ments.

go. 1 Venting lever 2 Venting button 3 Dosing amount adjustment knob

2. Set the dosing amount to 100%.

3. Press the ventilation button repeatedly until the de-

tergent comes out of the venting line on the under- side of the dosing pump without bubbles.

5. Turn the venting lever clockwise as far as it will go.

Refuelling DANGER Risk of fire Fuel can ignite. Observe the locally applicable regulations on the han- dling of fuel. Do not use unsuitable fuels as they can be dangerous. ATTENTION Risk of damage If the fuel tank is empty, the fuel pump runs dry and can get damaged. Check the fuel tank filling level regularly. Burner faults Incorrect fuel can lead to burner faults and poor com- bustion. Only use the fuel specified in the "Technical data" sec- tion. Use heating oil with a winter operation additives (flow improvers) if there is a risk of frost. Fuel overflow Fuel expands when warmed and can overflow. Do not fill the fuel container to the brim.

1. Unscrew the cap of the filling nozzle.

1 Filling nozzle 2 Filling level display 3 Inspection opening

2. Fill with fuel until the filling level display shows full.

Note Make sure that no fuel overflows and gets into the in- spection opening. During a later inspection, this fuel could be mistaken for leakage.

3. Close the filling nozzle.

Replenishing softening salt ATTENTION Malfunctions possible Unsuitable salt can interfere with the function of the base exchanger. Only use the softening salt in tablet form specified in the "Accessories" chapter.

1. Remove the lid of the salt tank.

2. Fill the salt tank to the top with softening salt.

3. Fit the lid of the salt tank.

Note An empty salt tank causes malfunction. Fill up the salt tank at the latest when water is visible in the salt tank af- ter removing the lid. Salt consumption does not increase when the salt tank is completely full. In a correctly working system, the salt consumption is constant in relation to the water consumption. We recommend documenting the salt and water con- sumption in an operating log. Frost protection The frost protection device consists of: ● Recirculation fan ● Hot air blower ● Frost protection circuit or frost protection with water loss ● Washing station heater ● Emergency frost protection ● Heating cartridge in the oil tank 몇 WARNING Danger of accident If there is black ice, there is a risk of accidents for the us- ers of the washing bay. Lock out washing stations when black ice forms to pre- vent black ice accidents. Note The following features are guaranteed: ● Unrestricted washing with the high-pressure spray lance down to -15°C. For systems with 4 washing stations, it is recommended to lock out one washing station below -10°C (for systems with 4 high-pres- sure modules type 908 already at warmer tempera- tures). ● Restricted washing with the washing brush at tem- peratures below 0°C. During restricted washing, all washing brushes must be checked regularly for ic- ing. Foam washing with an iced washing brush can damage the vehicle. If the washing brush is iced up, the following measures must be taken: 1-tool version: Replace the combination spray lance with a high-pressure spray lance. 2-tool version (option): Refrain from foam washing (e.g. by giving instructions to the user). ● At temperatures below –15°C, washing makes no sense because an ice coating forms on the vehicle. This ice coating can even impair the function of im- portant vehicle components. Therefore, prevent use of the system below -15°C by locking out the wash- ing stations. ● The system is frost-proof down to -20°C. Below - 20°C the device must be shut down as described in the section "Shutting down in case of frost". Prerequisites for frost protection ● The main switch must be in position 1. ● The doors of the system must be closed. ● An uninterruptible power supply, water supply and fuel supply must be ensured. ● The water supply must be protected against frost. ● The fuel supply must be protected against frost (e.g. heating cartridge in the tank, trace heating). ● Set up and install as described in the chapter "Set- ting up the system". ● The hot air blowers are set correctly. ● All maintenance measures described in the "Mainte- nance and care" chapter have been performed. ● All cleaning tools are returned to the storage com- partments. ● The trigger guns with frost protection bore belonging to the system are installed. Washing station heater Note A prerequisite for the correct functioning of the washing station heater is that the washing station is designed by the customer in accordance with KÄRCHER's recom- mendations. The washing station area that can be heated is limited by the corresponding heating capacity of the device. If the heated area exceeds this value, frost protection is not ensured. The number of washing stations that can be heated is given in the chapter "Technical data / data depending on hot water generation". Snow coating and larger quantities of ice chunks that have fallen off the vehicles require a very high heating capacity. It is necessary to remove these deposits.56 English Maintenance work before and after the frost period

1. Before the frost period begins, carry out mainte-

nance work "annually before the frost period be- gins", from the section "Maintenance and care".

2. To maintain frost protection, carry out the work listed

below. Note Maintenance work that is not carried out on time and in a professional manner will result in the loss of the war- ranty in the event of frost damage. 1 Washing station heater stop valve 1 Restrictor with sieve (marked red), 1-tool version 1 Frost protection pump filter Power foamClean the nozzle

1. Unscrew the front part of the nozzle.

1. Leave the main switch at position “1/ON”.

2. Lock the operating time at the controller.

3. Refill the fuel tank.

Shutting down If there is no danger of frost during the shutdown period:

1. Shut off the water inlet.

2. Disconnect the power supply.

Shutting down during frost If there is a risk of frost when shutting down, the follow- ing additional steps must be carried out.

1. Unscrew the water supply hose and the high-pres-

2. Remove the RO membrane and store it frost-free.

3. Empty all float tanks, remove the hoses and drain

5. Disconnect the water pipe between the base ex-

changer and the hot water float tank.

6. Flush the system (without base exchanger) with

frost protection solution.

7. Rinse the base exchanger with concentrated salt

8. Unscrew both hoses under the flow-through kettle

and let the water drain off.

9. Blow out all water-bearing parts with oil-free com-

pressed air. Note During longer breaks in operation, the system, with the exception of the base exchanger, must be rinsed with frost protection solution to protect it from corrosion In case of doubt, have the maintenance performed by Customer Service. Time & date Activity Performed By whom before the frost period Cleaning the filter in the Power foam noz- zle (option) Remove and clean the filter (see "Cleaning the Power foam nozzle filter"). Determine the following cleaning intervals according to experience. Operator Several times a day under frosty condi- tions Check the washing brushes Check the washing brushes for dirt and ice and lock the washing brush if necessary. Operator daily under frost con- ditions Clean the frost protection pump filter Clean the filter and insert it again. Operator Check the hot air blowers Are the hot air blowers in operation (also with ABS fuel tank, option)? Operator Check the recirculation fan Check the function. Operator daily at first, later ac- cording to experience Check the fuel tank filling level Is the heating oil supply sufficient until the next inspection? Take into account in- creased consumption due to frost protection devices. Lack of fuel leads to failure and damage to the system. Operator weekly during frost Check heating ABS fuel oil tank (option) Below 3 °C, check whether the trace heating of the fuel oil line between the heating oil tank and SB MB is warm. Operator monthly or after 200 operating hours in the event of frost, more frequently if required Check the frost protection water volume in the frost protection circuit Target value: approx. 0.5 l/min per washing tool. Water volume greater: Replace the node piece in the high-pressure gun. 몇 WARNING Risk of injury, risk of damage The high-pressure gun can move uncontrollably and cause injuries or damage if the frost protection water volume is too high. Be sure to replace the node piece in the high-pressure gun if the frost protection water quantity is too high. Water quantity smaller: Clean the frost protection pump filter, clean the sieve in the throttle, flush the pipe, check the direction of rotation of the pump.

The high-pressure jet is immediately available again when the high-pressure gun is opened again. The overflow valve is set and sealed at the factory. Set- ting must only be performed by Customer Service. Safety valve The safety valve protects the heating circuit of the wash- ing station heater (option) against overpressure. Thermostatic mixing valve The thermostatic mixing valve regulates the flow tem- perature for the washing station heater (option) depend- ing on the return temperature. Flame monitoring Only for devices with oil or gas burner. If the burner does not ignite or if the flame goes out dur- ing operation, the flame monitor closes the fuel solenoid valve and switches off the burner fan. Exhaust gas thermostat Only for devices with oil or gas burner. If the emission temperature rises above the permissible value, the emission thermostat switches off the burner and locks it. Temperature limiter Not for electrically heated devices without washing sta- tion heating. If the water temperature in the hot water float tank drops due to the withdrawal of hot water and cold water flow- ing in, the temperature controller switches the hot water circulation pump on and off again when the maximum temperature is reached. Temperature limiter Only for devices with oil or gas burner. The temperature limiter prevents steam from forming in the continuous flow boiler. Flow monitor Only for devices with oil or gas burner. The flow monitor switches the burner on once the hot water hot water circulation pump has started. Water shortage safeguard The water shortage safeguard shuts off the hot-water generator when the water level in the hot water float switch is too low. Dry running protection Only for electrically heated devices. Switches off the heating rod in case of overtemperature due to water shortage. Motor circuit breaker The motor circuit breaker interrupts the circuit when the motor is overloaded. Hard water sensor SB MB standard: If the residual hardness of the softened water exceeds a limit value, the controller calculates the residual ca- pacity of the base exchanger bottle. The regeneration of the base exchanger bottle is started the following night at the latest. SB MB comfort: If the residual hardness of the softened water exceeds a limit value, the regeneration of the base exchanger bottle begins immediately. Pressure sensor for water shortage RO If there is a water shortage, the system is stopped to prevent the RO pump from running dry. Buffer tank full level switch Switches off the RO pump when the permeate buffer tank is full. Pump RO ON level switch Switches on the pump RO to produce permeate. Buffer tank empty level switch Gives a signal to the system when the buffer tank per- meate is empty. Temperature limiter 4. Water type / hot (option) Prevents externally supplied hot water above 60°C from being directed to the high-pressure pumps and damag- ing them. In the event of a malfunction, the system switches to an alternative type of water (set by the service technician during commissioning). Care and service Maintenance instructions Regular maintenance according to the following mainte- nance plan is fundamental for a safely operating sys- tem. Use only original manufacturer spare parts or parts rec- ommended by the original manufacturer, such as ● Spare parts and wearing parts, ● Accessories, ● Operating materials, ● Detergent. DANGER Risk of injury Danger of death from electric shock. Switch off the device at the on-site main trigger and se- cure against being switched on again before working on the device.

3. Connect the spray lance to the high-pressure gun.

4. Tighten all union nuts hand-tight.

Water connection A category 5 system separator must be installed be- tween the system and the drinking water network to iso- late the system from the drinking water network. Locally applicable regulations must also be observed. Note Impurities in the inlet water can damage the system. Kärcher recommends using a water filter (see “Acces- sories”). ATTENTION Risk of damage Unsuitable water can damage the system. Only use water of drinking quality to supply the system. Observe the water quality requirements specified in the chapter "Intended use".

1. Feed the supply hose through the system opening

from below and connect it. For the connection values, see chapter "Technical da- ta".

4. Water type (option)

Processed water quality requirements: ● pH value: 6.5...9.5 ● Electrical conductivity: Conductivity of fresh water 1200 µS/cm, max. 2000 µS/cm ● settleable substances: < 0.5 ml * ● Filterable particles: < 50 µm ** ● Hydrocarbons: < 20 mg/l ● Chloride: < 300 mg/l ● Calcium: < 200 mg/l ● Total hardness: < 28 °dH, < 50° TH, < 500 ppm (mg CaCO

• Sample volume 1 litre / settling time 30 minutes ** no abrasive substances Electrical connection DANGER Risk of injury from electric shock If the power supply is not set up correctly, users can be killed or injured by electric shock. Have the power supply set up by an experienced elec- trician. ● The electrical connection must meet the require- ments of IEC 60664-1. ● The system must be protected by a fault current pro- tection switch with a trigger current no greater than 30 mA. ● A marked EMERGENCY OFF switch must be in- stalled in the supply line of the system at an easily accessible location from which the entire system can be switched off.

1. After connecting the system, check the direction of

rotation of the hot water circulation pump and the washing station heater circulation pump (option). Fuel line to external fuel tank Note The maximum permissible negative pressure in the fuel line (measured between the fuel filter and fuel pump) is

The negative pressure depends on: ● the pipeline length ● the suction height ● the control panels, branches and angles in the suc- tion line (dotted line in the diagram) ● the pipeline cross-section Note From +4 C, EL heating oil precipitates paraffin, which accumulates on the inner wall of the pipe. ● the viscosity of the heating oil (temperature-depend- ent) Measures against too high of negative pressure are: ● Minimum inner pipe diameter 6 mm ● short, preferably straight pipelines ● In extreme cases, use a separate fuel line with feed pump ● Preheat heating oil, provide suction line with trace heating ● Maximum viscosity 4...6 cSt at 20 °C ● If there is a risk of frost, use heating oil with additives (flow improvers) (winter fuel oil). Connect the washing station heater and start operation Note A prerequisite for the correct functioning of the washing station heater is that the washing station is designed by the customer in accordance with KÄRCHER's recom- mendations.

1. Connect the on-site pipes of the washing station

heater to the distributors in the device.

2. Mount the outdoor temperature sensor:

● protected from direct sunlight (north of the equator on the north side, south of the equator on the south side), ● protected from warm walls, ● protected from warm air currents.

3. Connect the immersion pump for filling the washing

station heater to the filling valve (on the red distribu- tor). 1 Flow line stop valve 2 Filling valve

4. Lay the return line from the filling valve of the blue

distributor to the tank with frost protection solution.

5. Open the flow stop valves and the filling valves.

6. Pump frost protection mixture into the system for

frost protection down to minus 25 °C.

7. Switch on the floor heating pump (see chapter "Con-

troller/Service menu").

8. Carry out the filling process until there are no more

bubbles in the return line.

9. Close the return filling valve (on the blue distributor)

and continue to fill in frost protection until the pres- sure gauge shows approx. 1.5 bar.

10. Close the filling line stop valve.

11. Let the underfloor heating pump run for at least an-

other 15 minutes. If necessary, top up with frost pro- tection until the pressure gauge shows 1.5 bar.

12. Remove the hose, collecting and disposing of the

remaining frost protection solution.

13. Check the hose and pipe connections for leaks.

14. Set the thermostatic mixing valve, see chapter "Set-

tings/Washing station heater", Checking the oil level

1. The oil level on all high-pressure pumps must be be-

tween the MIN and MAX marks on the oil tank. 1 Cover 2 Oil tank

2. Cut off the tip of the oil tank cover on each high-

pressure pump. Filling with operating materials

1. Fill with operating materials as described in the sec-

tion "Filling with operating materials". Note The softening salt is filled into the salt tank during the in- itial startup of the base exchanger. Therefore, do not add softening salt yet.English 79 Initial Start-Up

1. Open the water inlet.

2. Vent the hot water circulation pump by loosening the

venting screw and then tightening it again. 1 Venting screw

3. Turn the main switch to "1".

4. Vent the circulation pump frost protection by loosen-

ing the venting screw and then tightening it again. 1 Venting screw Putting the base exchanger into operation (WAT-SE.../255B) Backwash

1. Insert the overflow hoses of the base exchanger and

salt tank into the on-site waste water pipe.

2. Fill the salt tank with water (approx. 10 cm above the

upper edge of the sieve). Do not add salt yet!

3. Slowly open the fresh water stop valve and wait until

the pressure tank has filled with water.

4. Remove the cover of the control valve.

5. Press the programme button and select the "Back-

wash" function by turning it in the direction of the ar- row." 1 Programme button Air and water escape through the waste water con- nection until the system is completely vented. Note Limit backwashing to the absolute minimum, otherwise the sensor measuring cell may be exhausted and a complete regeneration of the respective exchange tank will be necessary.

6. Pull the suction sieve attached to the brine hose out

of the guide tubes in the salt container.

7. Press the valve flap NR1 (directly behind the pro-

gramme unit) with a screwdriver. The air shutter valve fills and air escapes through the suction sieve.

8. If no more air escapes from the suction sieve, re-

lease the valve flap.

9. Reinsert the suction sieve into the guide tubes.

1. Press the programme button and select the "Salt-

ing+Washing" function by turning it in the direction of the arrow." The water level in the salt tank decreases continu- ously. Note If air forms in the air shutter valve before the salt con- tainer is empty (residual level with empty salt container approx. 7cm) and the ball floating in the air shutter glass falls down, the suction system must be vented. Filling / washing clean

1. Press the programme button and select the

"Fill+Wash clean" function by turning it in the direc- tion of the arrow. The control valve automatically moves to the "Oper- ation" function. The salt tank is filled with water. Filling the salt tank
