2. Safety

2.1 Intended use

This appliance is intended 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.

This pressurised appliance is suitable for heating domestic hot water or for reheating preheated water. The appliance can supply one or more draw-off points.

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

2.2 General safety instructions

CAUTION Burns

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

There is a risk of scalding at outlet temperatures in excess of 43 °C.

CAUTION Burns

If operating with preheated water, e.g. from a solar thermal system, the DHW temperature may vary from the selected set temperature.

WARNING Injury

The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.

Where children or persons with limited physical, sensory or mental abilities are allowed to use this appliance, we recommend a permanent temperature limit. A qualified contractor can set the limit for you.

Material losses

The user should protect the appliance and its tap against frost.

2.3 CE designation

The CE designation shows that the appliance meets all essential requirements according to the:

• Low Voltage Directive
  Electromagnetic Compatibility Directive The maximum permissible mains impedance is indicated in chapter "Installation / Specification / Data table".

2.4 Test symbols

See type plate on the appliance.

Country-specific approvals and certifications: Germany

A general test certificate as verification of suitability regarding noise emissions has been issued for this appliance, based on the State Building Regulations [Germany].

AEG HOL DIN 4109 PA-IX 6814/I MPA NRW.

3. Appliance description

The electronically controlled instantaneous water heater with automatic output matching keeps the outlet temperature constant up to the output limit. The temperature is then selected via the draw-off tap.

Heating system

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

Note

The appliance is equipped with an air detector that largely prevents damage to the heating system. If, during operation, air is drawn into the appliance, the appliance shuts down for one minute, thereby protecting the heating system.

4. Settings

The DHW outlet temperature can be variably adjusted.

	Hand wash basin (approx. 35 °C)
	Shower (approx. 40 °C)
	Bath (approx. 45 °C)
	Kitchen sink (approx. 55 °C)

» Turn the temperature selector to the required temperature.

Temperature limit

Your qualified contractor can set a temperature limit of up to 43 °C inside the appliance. With the temperature limit enabled you can turn the temperature selector across its full range. You can now set the outlet temperature only between 30 °C and 43 °C.

Note

Should the outlet temperature fail to reach the required level with the draw-off valve fully open and the temperature selector set to maximum, then more water is flowing through the appliance than can be heated by the heating system. The appliance is at its output limit.

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

Recommended setting for operation with a thermostatic valve

Set the temperature at the appliance to the maximum temperature.

Following an interruption of the water supply

Material losses

In order to prevent the destruction of the bare wire heating system, return the appliance into use following an interruption of the water supply as follows:

» 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 tap outlets 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 voltage at the appliance.	Check the fuses/ MCBs in your fuse box/distribution panel.
	The flow rate is too low. The aerator in the tap or the shower head is scaled up or contaminated.	Clean and/or descale the aerator or shower head.
Required temperature >45 °C is not achieved.	The water supply has been interrupted.	Vent the appliance and the cold water inlet line (see chapter "Operation / Settings").
	The cold water inlet temperature is >45 °C.	Reduce the cold water inlet temperature.

If you cannot remedy the fault, notify your qualified contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-00000):

Nr.: 000000-0000-00000

INSTALLATION

7. Safety

Only a qualified contractor should carry out installation, commissioning, maintenance and repair of the appliance.

7.1 General safety instructions

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

Material losses Observe the maximum inlet temperature. Higher temperatures may damage the appliance. You can limit the maximum inlet temperature by installing a central thermostatic valve.

72 Instructions, standards and regulations

Note Observe all applicable national and regional regulations and instructions.

• The protection rating IP 25 (hoseproof) can only be ensured with a correctly fitted cable grommet.
  The specific electrical resistance of the water must not fall below that stated on the type plate. In a linked water network, factor in the lowest electrical resistance of the water (see chapter "Installation / Specification / Data table"). Your water supply utility will advise you of the specific electrical water resistance or conductivity.

Mono lever mixer tap, approx.	MPa	0.04 - 0.08
Thermostatic valve, approx.	MPa	0.03 - 0.05
Hand shower, approx.	MPa	0.03 - 0.15

Sizing the pipework

When calculating the size of the pipework, a pressure drop for the appliance of 0.1 MPa is recommended.

15.6 Fault conditions

In case of faults, loads up to a maximum of 95 °C at a pressure of 1.2 MPa can occur temporarily in the installation.

15.7 Details on energy consumption

Product data complies with EU regulations relating to the Directive on the eco-design of energy related products (ErP).
