CLAGE DLX Next Instant Water Heater
This document serves as a quick guide, operation manual, and installation guide for the CLAGE DLX Next series of instant water heaters. It is primarily presented in English, with some German content also present.
Product Overview
The CLAGE DLX Next is an electronically controlled, pressure-resistant instant water heater designed for efficient water supply to one or more tap outlets. Its electronic control system precisely regulates power consumption based on the selected outlet temperature, inlet temperature, and flow rate, ensuring consistent temperatures even with water pressure fluctuations. The outlet temperature can be easily set to 35°C, 45°C, or 55°C using the central sensor key.
The unit operates automatically, switching on when a hot water tap is opened and switching off when it is closed. It can also be used with an external load shedding relay for electronic instantaneous water heaters.
Diagram A1: Control Panel Illustrates the control panel with a central sensor key and three colored LEDs indicating temperature settings: 35°C (ECO), 45°C (COMFORT), and 55°C (HOT).
Environment and Recycling
This product was manufactured climate-neutrally according to Scope 1 + 2. For climate-neutral operation, the use of 100% green electricity is recommended.
Disposal of Transport and Packaging Material: Transport materials should be disposed of via specialist tradespeople or retailers. Sales packaging should be returned to the recycling loop via Germany's dual systems, separated by material.
Disposal of Old Products: Products marked with a crossed-out wheeled bin symbol must be disposed of separately from household waste. Return the unit to the manufacturer or a municipal collection point that recycles electronic devices. This ensures proper environmental protection and prevents potential harm to humans and the environment from improper disposal.
For disposal outside Germany, observe local regulations and laws.
How to Use
Temperature Setting
Use the temperature selection key to quickly choose one of three preset temperatures: 35°C for hand washing, 45°C for baths, and 55°C for cleaning. Each press cycles through the temperatures (35°C → 45°C → 55°C). The currently selected temperature is shown by one of the three colored LEDs.
For more detailed information, refer to the online operation and installation manual.
Venting After Maintenance Work
The unit features automatic air bubble protection but must be vented before first use and after any draining (e.g., after plumbing work, frost risk, or repairs). The process involves:
- Disconnecting the unit from the mains (e.g., via fuses).
- Unscrewing the jet regulator, opening the cold water tap to flush the pipe, and then repeatedly opening and closing the hot water tap until no air emerges.
- Reconnecting power and screwing the jet regulator back in.
- The heater activates after approximately 10-30 seconds of continuous water flow.
Cleaning and Maintenance
Clean plastic surfaces and fittings with a damp cloth only; avoid abrasive, solvent, or chlorine-based cleaners. Regularly unscrew and clean outlet fittings (e.g., jet regulators, shower heads) for optimal water delivery. Professional inspection of electrical and plumbing components is recommended every three years.
Troubleshooting and Service
Repairs should only be performed by authorized professionals. If a fault persists after consulting the table below, contact the CLAGE Customer Service Department. Ensure you have the device's typeplate details ready.
Before troubleshooting, try resetting the electronics by switching the house fuses off and on again.
| Problem | Cause | Solution |
|---|---|---|
| Water stays cold, temperature LED does not light up | Master fuse tripped | Renew or activate fuse |
| Water stays cold, temperature LED lights up | Safety pressure cut-out tripped | Contact customer service |
| Water stays cold, all LEDs flash | Safety thermal cut-out tripped | Contact customer service |
| Water heats up, all LEDs flash except temperature indication | Internal error / Appliance detected an error | Contact customer service |
| Flow rate of hot water too weak | Outlet fitting dirty or calcified; Fine filter dirty or calcified | Clean shower head, jet regulator, or sieves; Have fine filter cleaned by customer service |
| Temperature indication LED flashes during heating | Power limit reached; Cold water mixed at tap | Reduce warm water flow at tap; Tap only warm water, set temperature, check outlet temperature |
| Selected temperature not reached | Cold water mixed at tap | Tap only warm water, set temperature, check outlet temperature |
| Sensor key does not respond correctly or sporadically | Display is wet | Dry display with a soft cloth |

4. Installation
Installation must comply with all statutory regulations, local electricity and water supply company rules, and VDE 0100 / EN 806 standards.
Installation Site
Install in a frost-free room only. The appliance must be wall-mounted vertically with water connections downwards or transversely with connections to the left. It complies with protection type IP25 and can be installed in protection zone 1 (IEC 60364-7). Minimize distance to tap outlets to avoid thermal losses. Ensure the unit is accessible for maintenance. Plastic pipes must conform to DIN 16893 Series 2. The specific water resistance must be at least 1100 Ωcm at 15°C.
Installing the Wall Bracket
Rinse water supply pipes before installation. Screw in the provided nipples using a 12mm hexagon socket key. Hold the mounting template against the wall, mark drill holes, and drill with a 6mm drill bit. Open the appliance, remove the hood, and disconnect the control panel plug. Loosen the wall bracket's knurled nut, remove it, and screw it to the wall, using spacers to compensate for unevenness up to 30mm.
Installing Connection Pieces
Diagram D2: Water Connection Pieces Shows the cold and hot water connection pieces with union nuts and seals. Screw these onto the respective connections. Insert the water flow reducer "D" into the hot water connection piece, ensuring the O-ring is visible.
Note: Fasten union nuts moderately to ensure a seal without damaging components.
Installing the Appliance
The electrical power supply cable can be connected from the upper part; follow specific instructions in the online manual if applicable. Mount the appliance according to the provided diagrams.
5. Electrical Connection
This must be performed by a qualified electrician. Observe VDE 0100, local regulations, and the rating plate. The appliance must be earthed.
Wiring Diagram (Figure E1): Illustrates connections for the electronic circuitry, heating element, safety pressure cut-out (SDB), connecting terminal, and safety thermal cut-out (STB).
Electrical Connection from Below: Ensure power is switched off. Prepare the connection cable (approx. 6cm sheath removal), slide on the water splash protection sleeve, and connect cables to terminals according to the wiring diagram. Secure the splash protection sleeve. Reconnect the control panel cable, replace the hood, and tighten the screw. Ensure the cable is not pinched.
Structural Prerequisites: The appliance must be permanently connected and earthed. Wiring must be protected and inaccessible after mounting. An all-pole disconnecting device (e.g., fuses) with a contact opening of at least 3mm per pole is required. Use a fuse element appropriate for the appliance's nominal current.

Maintenance and Filter Cleaning
Diagrams G1, G2, G3: Filter Strainer Cleaning/Replacement Describe the process for cleaning or replacing the filter strainer in the cold water connection. This involves de-energizing the unit, closing the shut-off valve, removing the screw plug and strainer, cleaning/replacing the strainer, and reassembling. Venting is required after reassembly.
Maintenance work must be conducted by an authorized professional.
Initial Operation
Before initial operation, the unit must be vented. If the unit does not start, check if safety cut-outs (STB/SDB) have tripped during transport and reset them if necessary (refer to diagrams F1 & F2). Then, switch on the power, open the hot water tap, and check the unit's function. Explain the operation to the user and complete the guarantee registration.
