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 BurnsDuring 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 InjuryOnly a qualied contractor is permitted to remove the temperature selector. !

WARNING InjuryThe 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 mainte-nance 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 qualied contractor can set this limit. !

Material lossesThe user should protect the appliance and its tap against frost. !

Material lossesNever 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 pres-sure. » Never seal the tap outlet. » Only use special aerators for non-pressurised water heaters. » Never extend the tap outlet with a hose. !

Material lossesConnecting 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 sup-ply via a time switch. !

Operation – for users and qualied contractors

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 tempera- ture. 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 accesso-ries”). 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.26_02_06_00191212Huz 5 ÖKO ComfortHoz 5 Comfort1 Temperature selector2 Heat-up indicatorDepending on the system, the actual temperatures may vary from the set value.• Cold. On this setting, the appliance is protected from frost. The tap and the water line are not protected.E approx. 40 °Ce Recommended energy saving setting (approx. 60 °C), minor scaling

Note A qualied 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 sufcient for cleaning the appliance. » Check the tap regularly. You can remove limescale deposits at the tap outlet using commercially availa-ble descaling agents.Almost every type of water will deposit limescale at high temperatures. This settles inside the appliance and af-fects both the performance and service life. The heating elements should therefore be descaled if necessary. A qualied 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 se-lector is set to “•”. Switch the appliance ON by turning the temperature selector. No power at the ap-pliance.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 in-side the appliance. The appliance is scaled up. Have the appliance descaled by a quali-fied contractor.If you cannot remedy the fault, notify your contractor. To facilitate and speed up assistance, please provide the numbers from the type plate. Typ: E-Nr.F-Nr. : : 26_02_06_003115
