Frequently Asked Questions - HWE 860 Kärcher

What is the maximum temperature the HWE 860 can reach?

The maximum operating temperature is 85 °C. The actual temperature depends on water flow rate (e.g., 45 °C at 700 l/h with 15 °C supply).

How to adjust the water temperature?

Use the thermostat on the control cabinet. Turn it to the desired temperature. In manual mode, heating runs continuously according to the thermostat; in automatic mode, it depends on a timer or remote control.

What to do if the red light of the softener flashes?

The red light indicates that the liquid softener tank is empty. Fill it with RM 110 (see the manual for the location of the white tank).

How to descale the water heater?

Use RM 100 (ref. 6.287-008). Pour 30 l of water into the water heater, then 2 l of descaling acid. Circulate the solution without exceeding 60 °C. Add an additional 0.5 l if necessary. Wear gloves and safety goggles.

What precautions to take for transport?

Respect the weight of the device (24 kg without accessories) and secure it against sliding or tipping in the vehicle. Use suitable lifting equipment.

The device does not heat, what to check?

First check the power supply and fuses. If the protective circuit breaker has tripped, reset it. If the problem persists, contact customer service as the regulator or temperature limiter may be defective.

How to protect the device from frost?

Install the device in a frost-free location. In case of risk, completely drain the water and rinse with an antifreeze product to avoid damage.

What type of water to use?

The device can use tap water. In case of hard water, the liquid softener RM 110 reduces scaling. The dosing is preset at the factory but can be adjusted by customer service.

What are the dimensions and weight of the electrical cabinet?

The electrical cabinet weighs 18 kg and is an integral part of the device. The total dimensions of the HWE 860 are 440 x 508 x 751 mm.

Where to find spare parts?

Contact an authorized Kärcher dealer or customer service. Use only original parts. For descaling, RM 100 is available under reference 6.287-008.

Danger or hazard levels

DANGER

Pointer to immediate danger, which leads to severe injuries or death.

WARNING

Pointer to a possibly dangerous situation, which can lead to severe injuries or death.

CAUTION

Pointer to a possibly dangerous situation, which can lead to minor injuries.

ATTENTION

Pointer to a possibly dangerous situation, which can lead to property damage.

Proper use

• Only use appliance to generate hot water in connection with a high-pressure cleaner to clean machines, vehicles, buildings, tools, etc.
• If using cleaning agents other than water, check with dealer or customer service.
• When adjusting the temperature observe suitability for the pump and objects to be cleaned.

DANGER

Risk of injury! Follow the respective safety regulations upon employment at gas stations or other dangerous areas.

Please do not let mineral oil contaminated waste water reach soil, water or the sewage system. Perform engine cleaning and bottom cleaning therefore only on specified places with an oil trap.

Function

• With the HWE 860 you can heat water using electric energy. Its use is sensible everywhere, where the exhaust air of a burner poses a problem.
• The temperature that can be reached depends on the water volume that was put through, so the feed capacity of the used pump (median value see Specifications).
• The set temperature is controlled by a thermostat. If the switch unit is in the position "manual operation", the heater is always on via the thermostat. By switching to the position "automatic operation", the operation readiness also depends on a switch clock or an external remote control.
• The appliance also serves as a provision container for the high-pressure pump.
• The liquid softener prevents the calcification of the heating spiral while operating with calciferous tap water. It is dosed into the boiler drop by drop. The metering is set to a medium value by the manufacturer. This setting can be adjusted to local conditions by customer service.

Safety Devices

Temperature controller

The temperature limiter switches off the machine if the temperature regulator is defective.

Start up

Fill in liquid softener

• The white container for the liquid softener is located on the boiler.
• If the white container is empty, the red indicator lamp on the switch cabinet will blink. → Fill container with liquid softener (RM 110).

Operation

Operating elements

1 Indicator lamp (green) - heater on 2 Switch for manual/automatic operation 3 Indicator lamp (red) - fill level of liquid softener 4 Main switch 5 Control board

Turning on the Appliance

1 Temperature limiter 2 Temperature controller

→ Open the water supply. → Set temperature regulator to desired temperature. → Turn the main switch to position "1". → Set switch to manual or automatic operation.

We recommend the following cleaning temperatures:

– Light contaminations 30-50 °C - Contaminations containing protein, i.e. in the food processing industry max. 60 °C – Vehicle cleaning, machine cleaning 60 -85 °C

Note: If the working pressure and the flow rate are changed, the water temperature will change as well.

Turn off the appliance

Turn the switch for manual/automatic operation to position "0".

Shutting down

Turn the main switch to position "0".

Emptying the appliance

Shut off water supply. Unscrew the water inlet hose and high pressure hose from the appliance. Unscrew closing stopper on the bottom of the boiler and empty the boiler. Let the high-pressure pump run for max. of 1 minute, until the pump and pipes are empty.

Frost protection

The machine should be stored in frost-free rooms. In case there is frosting risk, for e.g. if the machine is installed in open areas, then the machine must first be emptied and flushed using an anti-freezing agent.

ATTENTION

Risk of damage! Frost will destroy the not completely water drained device.

Drain water. Flush device with anti-freeze agent. A certain corrosion protection is achieved with this as well.

Transport

CAUTION

Risk of injury and damage! Observe the weight of the appliance when you transport it.

When transporting in vehicles, secure the appliance according to the guidelines from slipping and tipping over.

Storage

CAUTION

Risk of injury and damage! Note the weight of the appliance in case of storage.

This appliance must only be stored in interior rooms.

Care and maintenance

DANGER

Risk of injury! The main switch is to be switched off while carrying out any repairs or maintenance jobs.

Visual check

Check the connection cables. The connection cable must not be damaged (risk of electrical shock). A damaged connection cable must be replaced immediately by an authorised Customer Service Engineer or an electrician. Check hot water hose. The hot water hose must not be damaged. A damaged hose must be replaced immediately (danger of burns).

Decalcify boiler.

Calcified appliances worsen the heat transfer and the efficiency is reduced.

DANGER

Risk of explosion due to combustible gases! Smoking strictly prohibited during decalcification. Ensure proper ventilation.

DANGER

Risk of burns injury on account of acid! Wear protective glasses and protective gloves.

According to statutory requirements, only tested and approved boiler decrusting agents may be used.

- RM 100 (Order No. 6.287-008) dissolves chalk and simple compounds of chalk and detergent residues.

→ Fill the boiler with 30 liters of water. → Connect the water hose directly to the water input and hang the other free end into the container. → Unscrew the nozzle of the steel pipe. Also insert the connected spray pipe of the high-pressure cleaner into the container. This is how a cycle is created: Container - pump - boiler. → Pour 2 l of decalcifying solution into the container. → Let the high-pressure pump run. → The solution must not become hotter than 60 °C. Ensure that there are no steam bubbles (do not mistake them for foam). → If there is no visible gas generation after 15 minutes, pour another 0.5 l of decalcifying solution into the container (max. concentration 7%). With regular decalcifying, this will only take approx. 3 minutes.

Troubleshooting

△DANGER

Risk of injury! The main switch is to be switched off while carrying out any repairs or maintenance jobs.

△DANGER

Risk of electric shock! The inspection of electrical components may only be performed by the authorized customer service.
