Safety

This open-vented (non-pressurized) appliance is designed for heat-ing domestic hot water. The appliance can supply one draw-off point. 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. Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of the instructions for any accessories used is also part of the correct use of this appliance.

General safety instructions

WARNING Burns

During operation, the tap can reach temperatures in ex-cess of 60 °C.
There is a risk of scalding at outlet temperatures in ex-cess of 43 °C.

WARNING Injury
The temperature selector should only be removed by a qualified contractor.

WARNING Injury
The appliance may be used by children aged 3 and older 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 aged 3 to 8 years are only allowed to operate the tap connected to the appliance. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless supervised.

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

Appliance description

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

Material losses
Never subject the appliance to water pressure. The tap outlet has a vent function. Scale build-up can block the outlet and subject the appliance to pressure.

Never seal the tap outlet.
Only use special aerators for non-pressurised water heaters.
Never extend the tap outlet with a hose.

Material losses
Connecting the appliance via a time switch will cause an unintentional reset of the high limit safety cut-out.

Never connect the appliance to the power supply via a time switch.

Test symbols
See type plate on the appliance.

The open-vented (non-pressurized) appliance constantly maintains the water content at the pre-selected temperature. During heating, expansion water drips from the tap. The appliance may only be installed with taps for open vented (non-pressurised) water heat-ers (see chapter “Installation / Appliance description / Required accessories”).

Operation
You can set any required DHW outlet temperature at the tem-perature selector. The heat-up indicator illuminates during the heat-up process.

```
1. Heat-up indicator  
```
Temperature selector

Depending on the system, the actual temperatures may vary from the set value.

* °C= Cold. On this setting, the appliance is protected from frost. The tap and the water line are not protected.

E= Recommended energy saving setting (approx. 60 °C), minor scaling
85= Highest selectable temperature

Note
A qualified contractor can set a temperature limit on the appliance (see chapter “Installation / Settings / Setting the temperature limit”).

Cleaning, care and maintenance

Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.
Check the tap regularly. You can remove limescale deposits at the outlet using commercially available descaling agents.

Almost every type of water will deposit lime at high temperatures. This settles inside the appliance and affects both the performance and service life. The heating elements should therefore be des-caled if necessary. A qualified contractor who is aware of the local water quality will tell you when the appliance should next be descaled.

Troubleshooting

Safety

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

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

Observe the type plate.

The following electrical connections are permissible:

Commissioning

WARNING Electrocution
Commissioning may only be carried out by a qualified contractor in accordance with safety regulations.

Initial start-up

* Either open the DHW valve of the tap or set the mono lever mixer tap to “hot” until the water that flows out is free of air bubbles.

Insert the plug into the standard socket or set the fuse/MCB in the fuse box.

Select a temperature.
Check the entire hydraulic installation for tightness.

Note
If you fail to follow the correct sequence (first water, then power), the high limit safety cut-out will trip.

Proceed as follows:

* Disconnect the appliance from the power supply.

Fill the appliance with water.

Connect the appliance to the power supply.

Settings

Appliance handover

* Explain the functions of the appliance to the user. Show the user how to operate the appliance.

Make the user aware of potential dangers, especially the risk of scalding.
Hand over these instructions and, if applicable, the instructions for any accessories.

Recommissioning
See chapter “Installation / Commissioning / Initial start-up”.

Settings

Setting the temperature limit

```
1. Temperature selector
```
Limiting ring

Placing the limiting ring behind the temperature selector allows you to limit the setting range of the temperature selector. The appliance temperature can be limited to either a maximum or minimum temperature.

The limiting ring has four holes and two end-stops around its edge. The holes are inscribed with temperature markings. Insert the limiting ring into the appliance cover so that the spike in the appliance cover pokes through one of the holes with a temperature marking. The inscription on the limiting ring must be visible after insertion.

Setting a maximum temperature of 45 °C, 55 °C, 65 °C

```
* Turn the temperature selector to zero (fully anti-clockwise to “°C”).
```
- Pull off the temperature selector and the limiting ring.
- Insert the limiting ring into the appliance cover so that the spike in the appliance cover pokes through the hole with the required temperature marking.
Install the temperature selector set to zero (°C).

The maximum appliance temperature is limited to the temperature indicated on the chosen hole.

Setting a minimum temperature limit > 65 °C

```
* Turn the temperature selector clockwise as far as it will go (85).
```
- Pull off the temperature selector and the limiting ring.
- Insert the limiting ring into the appliance cover so that the spike in the appliance cover pokes through the hole with the 55 temperature marking.
Install the temperature selector set as far clockwise as possi-ble (85).

The temperature can be set to between 65 and 85 °C.

Shutdown

Isolate the appliance from the power supply by removing the plug or by tripping the MCB in the fuse box.
Drain the appliance (see chapter “Installation / Maintenance /Draining the appliance”).

Troubleshooting

Maintenance

WARNING Electrocution
Before any work on the appliance, disconnect all poles of the appliance from the power supply.

Dismantle the appliance for maintenance work.

Draining the appliance

WARNING Burns
Hot water may escape during the draining process.

Drain the appliance via its connectors.

Opening the appliance

```
* Pull off the temperature selector and the limiting ring.
```
- Remove the screws from underneath the temperature selector.
Open the appliance cover by lowering the bolt screws in-wards and pivot the cover upwards, then remove it.

Descaling the appliance

Material losses
Never treat the cylinder surface with descaling agents.

Remove the flanged immersion heater.
Carefully tap the heating element to remove large limescale deposits.
Immerse the heating element up to the flange plate in desca-ling agent.

Checking the earth conductor

Pull off the temperature selector and the limiting ring.
Check the earth conductor (in Germany, e.g. DGUV3) across a temperature controller fixing screw and the earth conductor contact of the power cable.

Replacing the power cable
A qualified contractor must only replace the power cable with an original spare part. Alternatively, the H05VV-F3x1.0 cable may be used.

Positioning the temperature sensor in its protective pipe

When replacing the temperature controller, guide the tem-perature sensor into its protective pipe.
Secure the temperature sensor in place below the earthed plug.
