Frequently Asked Questions - WKM STIEBEL ELTRON

How to install the WKM mixing faucet?

Installation must be carried out by a qualified installer. Flush the cold water line, screw the water supply hoses to the tank and the mixing faucet. Use the faucet extension for tanks over 30 L. Open the hot water tap to fill the tank before commissioning.

How to adjust the water temperature?

Operate the right handle for hot water and the left handle for cold water. Mix by opening or limiting the flow of each handle until you reach the desired temperature.

What is the maximum flow rate of the WKM?

The maximum flow rate is 18 L/min when the mixing faucet is fully open. If the flow exceeds this value, you can restrict it using the limiter located on the wall connection.

How to clean and maintain the faucet?

Simply use a damp cloth. Do not use abrasive cleaning products or solvents. To descale the flow regulator, remove it from the spout and clean it.

Is there a risk of burns?

Yes, the temperature of the mixing faucet can exceed 60 °C in operation. There is a risk of burns if the outlet water temperature exceeds 43 °C. Be careful when using.

Can I use this mixing faucet with a pressurized tank?

No, the tank must not be pressurized. This mixing faucet is designed for free-flow domestic hot water tanks. Never block the water outlet to avoid pressurizing the tank.

What connections are available?

The connection is G 1/2 type. For installation, use the supplied water supply hoses. A faucet extension is available for tanks over 30 L.

How to descale the faucet?

Remove the flow regulator from the spout (it unscrews). Clean it with clear water or a mild descaler. Reassemble after drying.

What are the warranty conditions?

For devices purchased outside Germany, the warranty is provided by the local subsidiary. Use only original Stiebel Eltron parts to maintain the warranty.

Is this mixing faucet compatible with a hand shower?

The WKM model is designed for a sink and does not include a hand shower. The WDM (shower) and WBM (bath) models are intended for this use.

1.3 Units of measurement

Note

All measurements are given in mm unless stated otherwise.

2. Safety

2.1 Intended use

This product is intended for operation with an open vented (non-pressurised) oversink water heater.

• WKM for kitchen sinks
• WDM for showers
• WBM for baths

This product is designed for domestic use. It can be used safely by untrained persons. The appliance can also be used in a non-domestic environment, e.g. in a small business, as long as it is used in the same way.

Any other use beyond that described shall be deemed inappropriate. Observation of these instructions is also part of the correct use of this appliance.

3. Operation

Note

When the water in the water heater is being heated, expansion water will drip from the outlet.

With non-pressurised water heaters with anti-drip function, the expansion water remains inside the water heater.

Turn the right handle to draw off hot water.

Turn the left handle to draw off cold water.

To achieve the required temperature, turn both handles and adjust the mix of cold and hot water by increasing or reducing the respective flow rates.

WBM: You can switch between spout and hand shower. For this, pull the diverter upwards while the water is running.

The tap automatically reverts to the original position after draw-off has ended.

4. Cleaning and care

▶ Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning and caring for the product.
▶ For descaling, remove the aerator from the fitting.

INSTALLATION

5. Safety

Only qualified contractors should carry out installation, commissioning as well as maintenance and repair of the product.

5.1 General safety instructions

We guarantee trouble-free function and operational reliability only if original accessories and spare parts intended for the product are used.

WARNING Burns

During operation, the tap can reach temperatures in excess of 60 °C .

Material damage

Scale build-up can block the outlet and thus subject the water heater to pressure.

▶ Never block the spout, and use only aerators for non-pressurised taps, otherwise the water heater could be damaged.

5.2 Instructions, standards and regulations

Note

Observe all applicable national and regional regulations and instructions.

8.1 Checking the maximum flow rate

Material damage

With non-pressurised water heaters, observe the maximum permissible flow rate when the tap is fully open (see chapter "Specification / Data table").

▶ If the flow rate exceeds the stated value when the tap is fully open, reduce the flow via the butterfly valve in the wall connection.
▶ For this, remove the cap and turn the adjusting screw clockwise with a screwdriver.
