• This appliance is intended for use up to an altitude of 2000 m above sea level.

• The appliance may only be installed and stored in a frost-free room (due to residual water). WARNING The supplied water connection nozzles must be used and installed as shown in the supplementary sheets. Make sure that a check valve is installed in the cold water supply line. WARNING Risk of electric shock! Switch off the mains voltage supply immediately if a fault occurs. Disconnect the power supply before opening the appliance. Immediately shut off the cold water supply to the appliance should it leak. These installation instructions are intended for plumbers, heating engineers and electricians. All instructions must be observed. Failure to comply with instructions may result in material damage and personal injury, including possible loss of life. ▶ Read the installation instructions (heat source, heating controller, etc.) before installation ( chapter 2). ▶ Observe the safety instructions and warnings. ▶ Observe national and regional regulations, technical rules and guidelines.

• The statutory regulations of the respective country, as well as those of the local electricity and water suppliers, must be adhered to.

• The appliance must be permanently connected to installed pipes. The conductor cross-section must comply with the installed appliance power. CAUTION Earthed water pipes may give the appearance of a connected protective earth.

• To guarantee compliance to relevant safety regulations, an all-pole separator must be fitted during installation, according to chapter 3. The contact opening must be at least 3 mm.

• Do not use a steam cleaner. Safety of electrical devices for domestic use and similar purposes The following requirements apply in accordance with EN 60335-2-35 in order to prevent hazards from occurring when using electrical appliances: “This appliance can be used by children of 3 years and older, as well as by people with reduced physical, sensory or mental capabilities or lacking in experience and knowledge, if they are supervised and have been given instruction in the safe use of the appliance and understand the resulting dangers. Children shall not play with the appliance. Cleaning and user maintenance must not be performed by children without supervision.” “If the power cable is damaged, it must be replaced by the manufacturer, its customer service department or a similarly qualified person, so that risks are avoided.”Installation instructions Tronic 4000 | 5000 | 6000 | 7000 – 6720876037 (2021/08)

• Install the appliance as shown in the illustrations. Observe the instructions in the text.

Unpacking/Removing the cover (Fig. 1)

• Unpack the appliance and check for transport damage. If any components are damaged, then do not connect the appliance.

• Check that your appliance contains all components included in the scope of delivery: appliance, installation set with supplementary sheets, installation instructions, operating instructions.

• Please dispose of the packaging and the old appliance in an environmentally-friendly manner.

• When removing the cover from either a Type or Type appliance, please note the following: The Type cover is fastened by a central closure behind the service flap. The Type cover is attached by two screws located on the underside of the cover. Preparations for installation (Fig. 2) WARNING Important: Only use the supplied installation set. The supplied water connection nozzles must be installed!

• Shut off water supply. The electrical connection (connection cable) must be disconnected from the power supply. Unscrew the fuse or switch off the circuit breaker.

• Install the water connection nozzles according to the instructions on the supplementary sheet.

• The electrical connection cable can either be guided in at the top (X) or bottom (Y).

• The rear panel must lie against the cold water connection nozzle in the position provided for such (8.). Wall mounting (Fig. 3)

• The grommet must tightly surround the connection cable. If it is damaged during mounting, the openings must be provided with watertight sealing.

• The electrical supply terminal can be fitted at the top (X) or bottom (Y). The sheath of the connection cable must extend for at least 40 mm into the appliance.

• The distance to the wall is variable. You can compensate for any unevenness of the wall’s surface. With a distance to the wall of 8–16 mm, insert the spacer and install the extender (3.–5.).

• The appliance must be mounted securely on the wall in vertical position. If necessary, attach it at the lower adjustable screws (6.). Water connection (Fig. 4)

• Connect the water supply, then open the cold water supply.

• The appliance must be vented. To do so, open the warm water tap fully and flush out the appliance thoroughly for 1 minute. Electrical connection/Mounting (Fig. 5) Limiting the outlet temperature to 53 °C if unit used for shower purposes. WARNING Risk of electric shock! How to move the temperature limiting switch, ▶ Disconnect the power supply before opening the appliance. ▶ Remove the cover. ▶ Move the temperature limiting switch to the 53°C position ( Fig. 9).

• Only for appliances with power selector switches: Set the power using the power selector switch before connecting the wires to the mains connection terminal: Nominal output power left, reduced output right (1.) and the set output marked on the ratings plate.

• Screw the wires tightly into the mains connection terminal.

• Switch on the safety limiter (3.)

• Install the cover - according to either Type or instructions (4.–7.). Installation note

• The installation of non plug-in ready appliances must be undertaken by the respective utility operator or by a qualified specialist company, who can also assist you when you are requesting the approval of the utility company for installation of the appliance. Startup (Fig. 6) The device is compliant to IEC 61000-3-12. First start-up

• Switch on the fuses.

• Setting the temperature.

• Initial rinsing: Open the warm water tap fully and allow water to flow for at least 1 minute. Only then (for safety reasons) will the appliance begin to heat. Tip: Should the appliance not start because of a reduced flow-rate, remove the perlator, shower head or similar from the water tap before start and repeat the process.

• Explain the operation of the appliance to the user. Additional information (Fig. 7)

• If the appliance does not have sufficient water flow due to low water line pressure in your domestic plumbing system, remove the flow- rate limiter (1.–3.) or increase supply pressure to the system.

• The integrated flow restriction in the unit ensures a certain temperature increase in order to grant comfort, so removing this and in case the water pressure varies it can cause temperature fluctuations.

• The inlet filter must not be removed. It must always remain in the appliance even if flow restrictor is removed.

• Priority circuit for the combination with electrical storage heaters: For operation with a priority circuit, a special load shedding relay BZ 45L21 (special accessory) is required. Other existing load shedding relays, with the exception of electronic load shedding relays, may malfunction (Wiring diagram).

• The control electronics must be coded when operated with aloadshedding relay. Remove the keying nose on the electronics (4.).

• After anytime the unit is disconnected from power, e.g. at initial operation, power failures, air bubble detected, 6 l/min of water have to flow through appliance once. Only after this rinsing, the appliance starts heating up. The reason for this behavior is to remove air bubbles inside the heating element so a damage of the heating coils can be avoided.

• The safety limiter (SL) disconnects all electrical components in the event of a over-pressure or temperature. When the cause of theTechnical data

Water pressure peaks in installation due to flushing systems, pumping systems could trigger the SL, so pressure regulation valves are advised at supply line in order to minimize possible perturbations. 3Technical data

• Larger cable cross-sections may be required depending on the connection configuration. ** The pressure loss on the mixer must also be added.

Only for appliances that are suitable for solar heating systems: The appliance can only heat prewarmed water to a max. of 60 °C. If the cold water supply exceeds a temperature of 55 °C, the water will not be warmed any further. Important: The cold water supply temperature must not be higher than 55 °C! If the cold water supply exceeds a temperature of 60 °C, a circuit breaker will trigger and shut the appliance off. Therefore, the residential plumbing must be equipped with a thermostatic premixer that will limit the cold water supply temperature to a max. of 55 °C by appropriately mixing in cold water.
