Step 2: Power Disconnection

Ensure the main power supply is switched OFF before starting any electrical work. A symbol of a lightning bolt with a line through it (⚡️❌) indicates that power must be disconnected.

The diagram shows a switch being moved to the 'OFF' position.

Step 3: Wall Mounting Bracket

Mount the installation bracket securely to the wall. Drill holes of approximately 6mm diameter for wall fixings.

The diagram illustrates attaching a bracket to a tiled wall, with a dimension indicator for the drill bit size (Ø 6mm).

Step 4: Water Connections

Connect the water inlet and outlet pipes to the unit using the provided fittings. The connection point is indicated with a G 1/2" thread. Ensure secure connections using appropriate hardware, such as screws of size 4.2x38mm for mounting components.

Diagram shows pipe fittings, a hose clamp, and the G 1/2" thread connection. Dimensions and screw sizes are indicated.

Step 5: Unit Installation

Attach the main water heater unit to the previously mounted wall bracket. Arrows indicate the direction of attachment.

The diagram shows the unit being clicked or slid into place on the bracket.

Step 6: Electrical Connections

Connect the electrical supply to the unit. Ensure correct wiring to the terminals labeled L1 (Live), N (Neutral), and PE (Protective Earth). The diagram shows correct connections with a checkmark (✔️) and incorrect connections with a cross (❌).

The diagram illustrates the wiring terminals: L1, PE, N and L1, PEN, emphasizing correct earth connection.

Step 7: Water Flow Check

Connect the hot and cold water lines. After installation, check the water flow from the faucet. The diagram illustrates water flow paths with red arrows for hot water and blue arrows for cold water.

The diagram shows a faucet with water flowing, indicating the connection of hot and cold water supplies.

Step 8: Performance Requirements

The water heater requires a minimum water flow rate of 4 liters per minute (≥ 4 l/min). For optimal operation and heating efficiency, a minimum operating time of 1 minute is recommended. The '≥ 6x' symbol may indicate a significant heating performance factor.

Diagrams show flow rate requirements and a timer indicating a 1-minute duration, alongside temperature indicators.

Step 9: Internal View

An internal view of the water heater shows the arrangement of electrical wiring and water connections, including terminals for L1, PE, and N.

The diagram provides a look inside the unit, highlighting internal components and connections.

Step 10: Power On

Turn the main power switch to the 'ON' position to activate the water heater.

The diagram shows the switch being moved to the 'ON' position.

Step 11: Voltage Check

Verify the incoming voltage supply using a multimeter. The expected voltage is 230V, as indicated on the display reading '230.0'.

The diagram shows a multimeter measuring voltage (V), current (A), and resistance (Ω).

Step 12: Specific Settings (MPS)

⚠️ Consult Manual: Refer to the user manual for specific settings or troubleshooting related to 'MPS' (likely a system or safety parameter).

A person is shown with a warning symbol looking at a document, highlighting the need for specific information.

Product Specifications

The CLAGE DEX 12 Next model offers 8.8 kW of power, while the DEX 12 Next L model offers 11.5 kW.

This section lists the power ratings for the different models.

Step 14: Heating Time

The instantaneous water heater rapidly heats water, reaching its operating temperature within approximately 30 seconds (≥ 30 sec).

Diagrams show a timer and a thermometer, illustrating the quick heating process.

Step 15: Important Information

Pay close attention to important information and warnings provided in the documentation. Consult the manual for detailed guidance.

Troubleshooting (Fehler? / Error? / Erreurs?)

Issue 1: Electrical Connections

Check the electrical supply (L1, N, PE) and ensure all circuit breakers are in the 'ON' position. Verify correct wiring polarity.

Diagram shows electrical terminals and circuit breakers, with checks for correct connections.

Issue 2: Device Status

Confirm that the device is switched 'ON' and functioning. Check the display for any status indicators.

Diagram shows a person looking at a device with a '+' symbol and 'ON?' prompt.

Issue 3: Fuses

Inspect the fuses. Ensure they are the correct rating and properly seated. A diagram shows a correct fuse (✔️) and an incorrect one (❌).

Diagram illustrates fuse checks.

Issue 4: Mounting Clearances

Adhere to specific mounting clearances: ensure a gap of less than 2mm for one component and more than 4mm for another.

Diagram shows dimensions '<2mm' and '>4 mm' related to mounting.

Issue 5: STB Error

If encountering an 'STB?' error, consult the manual for specific troubleshooting steps related to the safety thermal cut-out (STB).

Diagram shows a device labeled 'STB?'.
