2. Description of appliance

This instantaneous water heater (fig. 1) is intended to provide economical heating of water sufficient for a single outlet i.e. kitchen sink or wash basin and can be installed with a sanitary water fitting. When the hot-water tap is opened, the heater switches itself on automatically when the minimum water flow rate is exceeded and heats the water as it passes through the appliance. The heater is pre-set in the factory to an out- let temperature of about 38 °C, which is ideal for washing your hands. When this tem- perature is reached, the electronic regulator reduces the power in order to ensure that the outlet temperature does not exceed this value. This automatic temperature regulation means that it is only necessary to open the hot water tap to obtain water at a constant, safe temperature for washing hands. On the control panel, the temperatures 35 °C, 38 °C and 45 °C can be selected. Cold water may be added if a lower temperature is required. If the flow rate is too low, if the flow pressure is too low, or if the warm-water tap is closed, the appliance switches itself off automatically. For an optimum flow of water, always fit the special jet regulator enclosed with the appliance. This regulator is inserted into the thread on the end of the tap and fits into any standard sleeve size M 22/24. The maximum possible outlet temperature is determined by the tem- perature of the incoming water, the rate of flow and the heating power of the heater (see diagram). The flow rate can be pre- set (“Adjusting the water flow”, 29).

The heater is installed as shown in the immediate vicinity of the outlet in a frost-free room. We guarantee trouble-free operation only if CLAGE fittings and accessories are used. Note the fol- lowing during installation:

• Installation must comply with DIN VDE 0100 and EN 806 and with the statutory regulations of the country and the provisions of the local electricity and water supply company.

• Check technical data and the information on the rating plate under the cover (“Removing the cover”, 28).

• Ensure that all accessories are removed from the packing materials.

• Easy access to the appliance shall be guaranteed at all times. An external shut-off valve has to be installed.

• Thoroughly rinse the water pipes before connection.

• Optimum operation is ensured at a water flow pressure of 0.2 to 0.4 MPa (2–4 bar). The appliance must not be subjected to pressure exceeding 1 MPa (10 bar).

• For safe operation of this instantaneous water heater, a non return valve is not required. If, nevertheless, a non return valve has to be installed, it may only be placed in the hot water outlet line behind the instantaneous water heater.

• The water pipes must not exert any mechanical force on the water connections of the instantaneous water heater during installation and operation. If this cannot be guaranteed due to the installation conditions, we recommend the use of flexible connections.

• The minimum requirements for the required water resistance must be complied with. The required water resistance of the can be obtained from your water supply company.

5. The following must be observed

The hot water temperature may not exceed 55 °C if the appliance is connected to a shower. If the appliance is operated with preheated water, it must be ensured that its temperature is also limited to 55 °C by the customer. Shower application24

• The permissible bending radius R min = 27 mm must be observed at all times, including during transport and assembly as well as when installed. If it is not possible to observe the minimum bending radius, a different installa- tion method should be used or a suitable hose should be selected. Please refer to the table for the minimum length:

• For curved installation there must be sufficient hose length available to form an open loop, as otherwise the hose will become kinked at the joints and thus destroyed.

• The hose length may change slightly due to the effects of pressure or heat. For straight installation, allowance should therefore be made to compensate for changes in the hose length.

• Never twist or kink the flexible connection.

• Ensure that the hose is never stressed by external tensile or compressive forces during assembly or when in use.

• Rigid connections (external thread) should not be further tightened after attaching the second connection, as this causes twisting and may damage the hose.

• The hose installer is always responsible for ensuring a tight join.

• The installer should check any sealing material supplied with the hose to ensure that it is suitable, as the hose manufacturer does not know the connection material or geometry.

• Install the appliance with the water connectors vertically upwards for direct connection to the sanitary tap.

• Secure the wall bracket to the wall with screws and suitable wall plugs (fig. 5).

• Place the appliance on the wall bracket and snap it into position (fig. 6). The appliance may only be operated, if it has been placed properly into the wall bracket!

• Tap connection (fig. 7): Cold water inlet (blue) and hot water outlet (red) are marked on the rating plate (under the rating plate cover).

• Connect the appropriate pipe or hose of the sanitary tap with the red-marked hot water outlet. Avoid exerting any kind of mechanical pressure on the appliance, e.g. by water pipes etc.

• After installation, carefully check all connections for leaks and rectify as necessary.

• In order to obtain an optimum water jet at low flow rates, always insert the enclosed jet regulator into the sleeve of the tap outlet. This insert fits commercially available sleeves with an M 22 or M 24 thread.

Removing the appliance from the wall bracket Put the wide screwdriver tip into the interlock between the water connections until it stops, then press slightly upwards (1), tilt the appliance forward by max. 15° (2) and remove it upwards (3).

Only by a specialist! Fill the appliance completely with water by repeatedly opening and closing the hot- water tap before connecting to electrical power. The heating element may be damaged if this is not done!

• Check that the power supply is switched off prior to electrical connection.

• The MCX 3 (3.5 kW) may be provided with a power cable and a protective earth plug by the factory. Please make sure that the feed cable, which leads to the protective earth plug socket, is dimensioned sufficient and that the socket is plugged to the conductor. The sock- et must be freely accessible. The power cable needs to be changed by the customer service department or an authorized electrician in case of defect, to avoid any danger.

• The mains cable of all other MCX models must be permanently connected via connecting box as shown in the circuit diagram (see fig. 9). The earth conductor must be connected.

• In accordance with IEC, a circuit breaker with a contact opening gap of at least 3 mm for each pole must be provided on the mains side of the connecting box.

• The wiring cross-section must be well adapted to the corresponding power rating.

• To protect the appliance, a fuse element must be fitted with a tripping current commensu- rate with the nominal current of the appliance.

(400 V 2~) MCX 7 To prevent damage to the appliance, the instantaneous water heater must be purged of air before using it for the first time.

Each time it is emptied (for example after work on the plumbing system or following repair work on the appliance), the instantaneous water heater must be purged before it is used again.

1. Switch off the power supply to the instantaneous water heater.

2. To purge the instantaneous water heater, open the hot water tap and wait until the water

emerges free of air bubbles.

3. Switch the power supply back on again.

Do not switch on the electric power at this time!

1. Open the hot-water tap and allow water to flow until it emerges free of air bubbles.

2. Now close the circuit breaker to connect the electrical supply. After a short power-up delay,

3. Set the desired outlet temperature and adjust the water flow rate, if, for example, the tem-

perature cannot be reached.

4. Explain the functions of the heater to the user and ensure that he knows how to use it.

Hand over these operating instructions to the user.

5. Use the registration card for the registration at the factory service centre or register the

appliance online on the website www.clage.com.28

3. Remove the cover by pulling forward.

11. Rating plate cover

1. Push the cover flat towards the wall bracket under the

edges of the water connections.

2. Press down the front edge of the cover and push it forward

again at the rear edge until it fits. Rating plate cover On the inner part of the cover, you can find the name of the appli- cation type (1), as well as the serial number (2) and the article number (3). Gerät an Schutzleiter anschließen! Appliance must be earthed! CLAGE GmbH

May only be carried out by a specialist. Remove the cover (see Fig. 10), undo the hood screw underneath and remove the hood. Decreasing the flow rate: Turn the adjusting screw clockwise to decrease the flow rate, thus making a higher outlet temperature possible. Increasing the flow rate: Turn the adjusting screw counter-clockwise to increase the flow rate, thus reducing the pos- sible outlet temperature.

12. Adjusting the water flow

Temperature setting The touch key allows you to select one of the three preset temperatures. Every key press sets the temperature to the next level: 35 °C 38 °C 45 °C (max.) Press the key once again starts the cycle all over. The current selected temperature is indicated by one of three coloured LEDs.

Three coloured LEDs Touch key Direction Flow Tem pe ra ture in crease

Key lock and temperature lock The current selected temperature setting can be locked against unintended alteration. Thus, the temperature cannot be changed by a single keypress anymore. Activate keylock / Deactivate keylock: Press and hold touch key for approx. 5 seconds until the active LED goes out, then release the touch key.

As an energy-saving function of the control panel, the active LED automatically goes out approx. 20 seconds after the last operation (e.g. tapping or temperature selection). However, in order to be able to recognise the selected setting at any time, the LED can be permanently activated and the LED standby function deactivated with the following procedure:

• Press and hold the sensor button (approx. 7-8 seconds). After approx. 5 seconds, the active LED goes out. Continue to hold down the sensor key.

• The green and yellow LEDs light up to indicate activation/deactivation. Release the sensor key. If the fitting is opened in LED standby mode (LED off) or the sensor key is pressed, the last active LED lights up (wake-up), but the temperature is not yet switched over. The temperature can only be adjusted when the button is pressed again. The LED standby function can be reactivated in the same way. This function remains stored even in the event of a power failure. For the professional! For thermal cleaning of the flexible hose and fitting, the outlet temperature can be set to ≥50 °C for the next tapping. When the service rinse function is active, showering is not permit- ted due to the high temperatures.

• Press and hold the sensor button (approx. 10-12 seconds) until the red and yellow LEDs light up. Release the sensor key.

• Open the hot water valve on the fitting. To reach the maximum temperature, reduce the flow at the fitting or the angle valve until the red and yellow LEDs light up continuously.

• The function is deactivated as soon as another temperature is set or the flow falls below the minimum for 30seconds (water stop).31 CLAGE

17. Cleaning and Maintenance

• The appliance and the fittings should only be cleaned with a damp cloth. Do not use abra- sive or chlorine-based cleaning agents or solvents.

• Keep the control panel area dry!

• Clean the jet regulator or the hand-shower regularly and replace as necessary.

• Dirt and scale deposited in the pipes and heater will affect the function of the heater. Typical indications include reduced rate of flow or noisy flow. In such cases, have the heater inspected by a technician and, if necessary, have the filter in the cold-water inlet cleaned.
