Gebrauchsanleitung (Operation Instruction)

1. Gerätebeschreibung (Description of the appliance)

The CLAGE DCX Next / DCX13 Next is an electronically controlled, pressure-resistant instantaneous water heater designed for efficient water supply to one or more tap connections. Its electronic control system precisely regulates power consumption based on the selected outlet temperature, inlet temperature, and flow rate, ensuring the set temperature is maintained even with fluctuating water pressure. The outlet temperature can be adjusted to 35°C, 38°C, 42°C, 48°C, or 55°C using the central sensor key.

In conditions of low inlet temperature and high flow rate, the preset outlet temperature may not be reached if the appliance's capacity is exceeded. Reducing the hot water flow at the tap can help increase the outlet temperature.

The unit can be operated with an external load shedding relay for electronic instantaneous water heaters.

The water heater automatically switches on when the hot water tap is opened and switches off when the tap is closed. Operation is possible directly on the device or via an optional wireless remote control.

Device Information: Press and hold the temperature selection key for 10 seconds to enter the info mode. LEDs indicate device status: Left bottom LED shows water flow status (OFF: no flow, FLASHING: below switch-on point, ON: above switch-on point). Middle top LED indicates heating status (ON: heating active, FLASHING: power limit). Right bottom LED indicates device status (OFF: OK, FLASHING: error detected).

2. Umwelt und Recycling (Environment and Recycling)

This product is made from high-quality, reusable materials. Please dispose of electrical devices separately from household waste at the end of their service life. Take the appliance to a municipal collection point for recycling. Proper disposal supports environmental protection and prevents potential negative impacts on human health and the environment.

For information on the nearest collection point or recycling center, contact your local authority. Business customers should contact their dealer or supplier for disposal information.

3. Gebrauch (How to use)

Temperature Setting

Use the temperature selection key to quickly choose one of five preset temperatures for common hot water applications: 'Hand wash' (35°C), 'Shower' (38°C), 'Bath tub' (42°C), 'Kitchen' (48°C), and 'Cleaning' (55°C). Each press advances to the next temperature level, cycling back to 35°C after 55°C. The selected temperature is indicated by one of five colored LEDs.

Power Limit

If the appliance's full output is insufficient to heat the water, the temperature LED will flash. This may occur in winter or when multiple taps are open simultaneously. Reducing the hot water flow rate will cause the LED to light up continuously again, indicating sufficient output.

Venting after maintenance work

The appliance has automatic air bubble protection but must be vented before first use and after any draining (e.g., due to plumbing work, frost risk, or repairs). To vent:

1. Disconnect the appliance from the mains (e.g., switch off fuses).
2. Unscrew the jet regulator from the outlet fitting and open the cold water tap to flush the pipe and prevent contamination.
3. Open and close the hot water tap repeatedly until no more air emerges.
4. Reconnect the power supply and screw the jet regulator back in.
5. The heater activates after approximately 10 seconds of continuous water flow.

Cleaning and Maintenance

Wipe plastic surfaces and fittings with a damp cloth only. Avoid abrasive, solvent-based, or chlorine-based cleaning agents.

Regularly unscrew and clean outlet fittings (aerators, shower heads) for optimal water supply. Have electrical and plumbing components inspected by a qualified professional every three years to ensure proper function and safety.
