2.1 Intended use

This open vented (non-pressurised) 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.

2.2 General safety instructions

WARNING 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.

WARNING Injury

Only a qualified contractor is permitted to remove the temperature selector.

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-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.

2.3 Test symbols

See type plate on the appliance.

3. Appliance description

The open vented (non-pressurised) 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 heaters (see chapter "Installation / Appliance description / Required accessories").

thermostop function

The thermostop function (thermal separation) of the Huz 5 ÖKO Comfort prevents the tap becoming hot in standby mode.

3.1 Operation

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

  e Recommended energy saving setting (approx. 60 °C), minor scaling

Note

A qualified contractor can set a temperature limit on the appliance (see "Installation / Settings / Setting the temperature limit").

4. 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 tap outlet using commercially available descaling agents.

Almost every type of water will deposit limescale 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 next descaling is due.

5. Troubleshooting

Problem	Cause	Remedy
The appliance does not supply hot water.	The temperature selector is set to “•”.	Switch the appliance ON by turning the temperature selector.
	No power at the appliance.	Check the plug / fuses in the fuse box.
Water can only be drawn at a reduced rate.	The aerator in the tap is scaled up.	Descale / replace the aerator.
Loud boiling noises inside the appliance.	The appliance is scaled up.	Have the appliance descaled by a qualified contractor.

If you cannot remedy the fault, notify your contractor. To facilitate and speed up assistance, please provide the numbers from the type plate.
