Safety

Intended use

This open vented (non-pressurized) appliance is designed for heating 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 instructions for any accessories used is also part of the correct use of this appliance.

General safety instructions

WARNING Burns There is a risk of scalding at outlet temperatures in excess 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 8 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 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 this limit.

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-pressurized 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.
Information for Australia/New Zealand:
Installation complies with standard AS/NZS 3500.4.

Appliance description

The open vented (non-pressurized) appliance constantly maintains the water content at the pre-selected temperature. The appliance may only be installed with taps for open vented (non-pressurized) water heaters (see chapter “Installation / Appliance description / Accessories”).

thermos top function
The thermos top function (thermal separation) prevents the tap becoming hot in standby mode.

Anti-drip function
The anti-drip function prevents expansion water from escaping from the tap during heating. When water is heated, gas bubbles are formed. The amount of gas bubbles depends on the water quality. At temperatures > 75 °C the rising gas bubbles can cause residual water to drip from the tap outlet.
Subject to design, some taps have a tendency to drip for a short while after being closed. This dripping is caused by residual water escaping from the tap outlet and is not linked to expansion water.

Operation

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

1. Temperature selector
2. Heat-up indicator

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.
Eco = 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 descaled if necessary. A qualified contractor who is aware of the local water quality will tell you when the appliance should next be descaled.

Troubleshooting

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

Safety

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

  • Secure the water connections from the tap to the appliance.

Note Ensure that the water connections are not kinked during installation. Prevent any tensioning during installation.

Power supply

WARNING Electrocution Carry out all electrical connection and installation work in accordance with relevant regulations.
WARNING Electrocution When permanently connected to the power supply using a dedicated junction box, the appliance must be able to be isolated from the mains power supply by an isolator that disconnects all poles with at least 3 mm contact separation.
WARNING Electrocution Ensure that the appliance is earthed.

Material losses
The voltage specified on the type plate must match the mains voltage.

• 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 The high limit safety cut-out will respond if you fail to follow the correct sequence (first water, then power). Proceed as follows: Disconnect the appliance from the power supply. Fill the appliance with water. Connect the appliance to the power supply.

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
2. Limiting ring

Placing the limiting ring behind the temperature selector allows you to limit the setting range of the temperature selector to a specific maximum temperature.

• Turn the temperature selector to zero (fully anti-clockwise to “°C”).
• Pull off the temperature selector and the limiting ring.
• Push the limiting ring with the required maximum setting onto the controller shaft.
• Install the temperature selector set to zero (°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

Service

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 inwards 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 descaling agent.

Cleaning the strainer

• Detach the “cold water inlet” connection.
• Using pliers, remove the strainer from the “cold water inlet” connection.
• Descale or replace the strainer.

Checking the earth conductor

• Pull off the temperature selector and the limiting ring.
• Check the earth conductor (in Germany, e.g. BGV A3) across a temperature controller fixing screw and the earth conductor contact of the power cable.

Replacing the power cable

The power cable must only be replaced by a qualified contractor with an original spare part. Alternatively, the H05VV-F3x1.0 cable may be used.

• Route the power cable along the cable guide.

Positioning the temperature sensor in its protective pipe

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