3. Appliance description

The hydraulically controlled instantaneous water heater heats water as it flows through the appliance. When a tap is opened, the heating output starts automatically as soon as the start-up volume is exceeded (see chapter «Specification / Data table»). The water volume and temperature can be adjusted at the tap.

You can choose between 2 output stages. In addition, 2 output stages are hydraulically controlled in relation to the flow rate.

The flow rate controller compensates for pressure fluctuations, thereby ensuring largely stable temperatures. The controller limits the throughput, thereby ensuring an adequate increase in the DHW temperature at all times.

Heating system

The bare wire heating system has a pressure-tested plastic casing. The heating system is suitable for hard and soft water areas and is largely insusceptible to scale build-up. This system ensures rapid and efficient DHW availability.

4. Settings

1 Partial load

At low throughput 1/3 of the heating output is activated; at higher throughput 2/3 of the available heating output is enabled. This setting is suitable for hand washing at a basin, for example.

2 Full load

At a low throughput, 50% of the heating output is applied; at a higher throughput the full heating output is activated. This setting is suitable for washing dishes, for example.

» Click the output selector into the required position.

Recommended settings when using a thermostatic valve

» Set the output selector to full power.

4.1 Recommended tap/valve settings

Note

If the outlet temperature is not sufficiently high at full load and with the draw-off valve fully open, then more water is flowing through the appliance than can be heated by the heating system (appliance is at its output limit).

» Reduce the water volume at the draw-off valve.

Low draw-off rate = high outlet temperature

High draw-off rate = low outlet temperature

Twin lever tap

Output stage Application range
Partial load Washbasin
Full load Bath, shower, sink

» Add cold water if the temperature is too high when the tap is fully open.

Mono lever mixer

Output stage Application range
Full load All

Turn the tap lever to the highest temperature.

Fully open the tap. Increase the outlet temperature by closing the tap slowly. Reduce the outlet temperature by adding cold water or opening the tap further, if possible.

Following an interruption of the water supply

Material losses

Following an interruption of the water supply, the appliance must be recommissioned by carrying out the following steps, in order to prevent the destruction of the bare wire heating system.

Disconnect the appliance from the power supply by removing the fuses/tripping the MCBs.

Open the tap for one minute until the appliance and its upstream cold water inlet line are free of air. Switch the mains power back ON again.

5. Cleaning, care and maintenance

Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

Check the taps regularly. Limescale deposits at the spouts can be removed using commercially available descaling agents.

6. Troubleshooting

Problem	Cause	Remedy
The appliance will not start despite the DHW valve being fully open.	There is no power.	Check the fuses/ MCBs in your fuse box/distribution panel.
	The flow rate is too low for switching on the heating output. The aerator in the tap or the shower head is scaled up or contaminated.	Clean and/or descale the aerator or shower head.

3. Description of the device

The instantaneous water heater with hydraulic control heats water as it flows through the device. When the fitting is opened and the flow rate exceeds the minimum required for activation (see section “Technical data / Parameter table”), the device automatically starts heating. The flow rate and temperature of the hot water can be adjusted using the fitting.

You can select one of 2 power levels. In addition, hydraulic control of the power level depending on the flow rate is provided.

The flow rate control compensates for pressure fluctuations, thereby ensuring a practically constant temperature. The flow rate control limits the flow, so the tap water is always heated to a sufficient temperature.

The heating system with an open heating element is protected by a sealed plastic housing. The heating system is suitable for both soft and hard water, as it is practically insensitive to scale formation. The heating system ensures fast and efficient supply of hot water.

4. Settings

1 Partial power

At a low flow rate, 1/3 of the heating power is used, at a higher flow rate - 2/3. This setting is suitable, for example, for washing hands.

2 Full power

At a low flow rate, half of the heating power is used, at a higher flow rate - full power. This setting is suitable, for example, for washing dishes.

Fix the power regulator in the lower position.

Recommended setting when using a thermostat on the fitting

Set the power regulator to the full power position.

4.1 Recommended setting for fittings

Note

If the hot water tap is fully open and the heating power is set to maximum, but the water at the outlet still has insufficient temperature, this means that more water is passing through the appliance than the heating element can heat (the appliance's maximum power has been reached).

In this case, it is necessary to reduce the water flow at the distribution valve.

Low flow = high outlet temperature

High flow = low outlet temperature
