Instantaneous water heater

Installation instructions Install the continuous-flow heater as described in the illustrated section. Observe the instructions in the text. Safety information Risk of electric shock! Switch off the mains voltage supply immediately if a fault occurs. Installation

Unpacking/Removing the cover ■ Unpack the appliance and check for transport-related damage. ■ Please dispose of the packaging, and if applicable, the old appliance in an environmentally-friendly manner. II. Preparations for installation ■ We do not accept liability for damage resulting from failure to heed these instructions. Important: Only use the supplied installation set. The supplied water connection nozzles must be installed! ■ The continuous-flow heater may only be connected and put into operation by a qualified professional. ■ 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. ■ Never open the appliance without disconnecting the power supply beforehand. ■ The statutory regulations of the respective country, as well as those of the local electricity and water suppliers, must be adhered to. ■ The continuous-flow heater is a Class I appliance and must be connected to the protective earth. ■ 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. The contact opening must be at least 3 mm. ■ The continuous-flow heater is only suitable for closed (pressurized) operation. ■ The tap and outlet fittings must be approved for operation with closed (pressurized) continuous-flow heater systems. ■ The continuous-flow heater can be operated with cold or pre-warmed water (for example, from a solar energy unit water supply). Observe the technical data and the special accessories for this purpose. ■ Only connect the continuous-flow heater to a cold water line. ■ The continuous-flow heater may only be installed in a frost-free room. ■ Disconnect the electrical connection cable from the supply and shut off the water supply before connecting the appliance! ■ Connect the water supply and then connect the electrical supply. ■ Only make the openings which are required for installation on the rear of the appliance. If the appliance is reinstalled, the unused openings must be provided with watertight sealing. ■ Do not touch electrically live parts after installation.

III. Wall mounting ■ The continuous-flow heater must be mounted on the wall. Attach it if necessary on the lower adjustable screws. ■ The distance to the wall is variable. You can compensate for any unevenness of the wall's surface. ■ The grommet must tightly surround the connection cable. If it is damaged during mounting, the openings must be provided with watertight sealing. IV. Water connection ■ The continuous-flow heater must be vented. The warm water tap must be opened and the appliance must be flushed out thoroughly for 1 minute with at least 6 litres of water.

Electrical connection/Mounting ■ The electrical supply terminal can be fitted at the top or bottom. The sheath of the connection cable must extend for at least 40 mm into the appliance. VI. Startup/additional information First start-up ■ Switch on the fuses. ■ Setting the temperature. ■ Starts rinsing: Open the warm water tap and allow water to flow for at least 1 minute (flow-rate at least 6 litres per 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 before start and repeat the process. ■ Remove the flow-rate limiter (see Fig. A) with low water pressure. ■ Explain the operation of the continuous-flow heater to the user.

If the continuous-flow heater does not have sufficient water flow due to low water line pressure in your domestic plumbing system, remove the flow-rate limiter.

Priority circuit for the combination with electrical storage heaters: For operation with a priority circuit, a special load shedding relay BZ 45L20 (special accessory) is required. Other existing load shedding relays, with the exception of electronic load shedding relays, may malfunction.

LED Appliance status Off Off Lights up Ready Slow flash (1/s) Appliance is heating Fast flash (4/s) Desired water temperature is not reached (water flow too high for appliance rating). The control electronics must be coded when operated with a load shedding relay.

The filter upstream from the check valve in the cold water supply inlet is clogged. Remove the filter and either clean it or descale it. See Figure E 1–3. Technical data DEE 1803 DEE 2103 DEE 2403 Rated output [kW]

Operating instructions Please read the operating instructions carefully before you use the appliance! Safety information ■ This appliance is intended for domestic use or for household-based non-commercial applications. Householdbased applications include, e.g. usage in employees catering facilities for shops, offices, agricultural and other commercial operations, as well as usage by guests of guest houses, small hotels and similar residential establishments. Risk of electric shock! Switch off the mains voltage supply immediately if a fault occurs. ■ We do not accept liability for damage resulting from failure to heed these instructions. ■ The continuous-flow heater may only be connected and put into operation by a qualified professional. ■ Repairs may only be undertaken by a suitably qualified specialist to avoid potential sources of danger. ■ The continuous-flow heater may only be installed in a frost-free room. With the use of a thermostat battery, the following settings are recommended for high temperatures or large quantities of water, for example: Dish washing Cleaning Bath tub ■ Turn on the hot-water tap. The continuous-flow heater switches on and heats the water when the hot-water tap is turned on. It switches off again when the tap is turned off. Changing the supply water temperature correspondingly changes the outgoing water temperature. Increasing the water temperature ■ Persons (including children) with diminished bodily, sensory or mental perception, or those who lack knowledge or experience should not operate the appliance, unless they are monitored or have received instruction concerning use of the appliance by persons responsible for their safety. ■ Keep children away from the appliance. Please monitor children to ensure that they do not play with the appliance. ■ The mixer and the warm water pipe may be hot . ■ Please switch off all fuses immediately if a malfunction occurs. Immediately shut off the cold water supply to the appliance should it leak. The malfunction can only be repaired by a specialist or an authorised service agent. If a higher temperature for a completely opened warm water tap is not achieved, more water flows than the flow-through heater can warm as a result its performance capabilities. In this case, the warm water tap must be closed somewhat. Decreasing the water temperature Your new appliance The electronically regulated flow-through heater warms the water while it flows through the unit. How to operate the continuous-flow heater The warm water temperature can be continuously adjusted on the electronically regulated flow-through heater: Startup after a water cutoff ■ Switch off the appliance (unscrew the fuse in the house electrical installation). ■ Turn on the hot-water tap until the air is purged from the pipe. ■ Switch the fuse back on again. The appliance is ready for operation. Washbasin Shower

Saving energy Cleaning ■ Set the desired warm water temperature directly on the flow-through heater. Simply wipe the appliance with a damp cloth. Do not use intensive or abrasive cleaning agents. Mixing with cold water at the armature for water that is too hot consumes unnecessarily water and energy. At approx. 40 °C (temperature selection position unit operates most economically. ) the A fault, what to do? If your appliance does not operate as required, it is often due to a very minor problem.
