OPERATION

APPLIANCE DESCRIPTION

6 | DHM 6 220 www.stiebel-eltron.com

3. Appliance description

The hydraulically controlled mini instantaneous water heater
heats the water directly at the draw-off point. The heating system
starts automatically when the tap is opened. The short pipe runs
ensure that energy and water losses are minimal.

The DHW output depends on the cold water temperature, the heat­ing output and the flow rate.

The bare wire heating system is suitable for hard and soft water
areas. This heating system has a low susceptibility to scale build­up. The heating system ensures quick and efficient DHW provision
at the hand washbasin.

Fitting the special aerator supplied provides an optimum water jet.

4. Settings

The appliance heating system switches on automatically as soon
as you open the DHW valve at the tap or activate the sensor of a
sensor tap. The water is heated. The water temperature can be
adjusted at the tap:

For the start volume, see chapter “Specification/ Data table/ On”.

Increasing the temperature

 Reduce the flow rate at the tap.

Reducing the temperature

 Open the tap further or add more cold water.

Following an interruption of the water supply

See chapter “Commissioning/ Recommissioning”.

5. Cleaning, care and maintenance

 Never use abrasive or corrosive cleaning agents. A damp

cloth is sufficient for cleaning the appliance.

 Check the taps/valves regularly. Limescale deposits at the

spouts can be removed using commercially available descal­ing agents.

 Have the electrical safety of the appliance regularly checked

by an electrician.

 Regularly descale or replace the special aerator (see chapter

“Appliance description/Accessories”).
