Description of the appliance

The E-basic instant water heater DBX Next is an electronically controlled pressure-resistant instantaneous water heater for an efficient water supply to one or more tap outlets.
As soon as you open the hot water tap, the instantaneous water heater switches on automatically. When the tap is closed, the appliance automatically switches off. Its electronic control regulates the power consumption depending on the selected outlet temperature, the respective inlet temperature and the flow rate, thus reaching the set temperature exactly to the degree and keeping it constant in case of water pressure fluctuations. The factory set outlet temperature is 50 °C. This factory setting can be adjusted in the appliance to be in a range of approx 30 °C and 60 °C by a specialist only.
Note: The hot water temperature may not exceed 55 °C if the instant water heater is connected to a shower.
In case of a low feed temperature and a high flow rate at the same time, it could happen that the preset outlet temperature is not reached which is due to the fact that the appliance exceeded its capacity. The outlet temperature can be raised by reducing the water flow at the tap. It is possible to use the instantaneous water heater in combination with an external load-shedding relay for electronically controlled instantaneous water heaters (refer to installing instructions).

How to use

Venting after maintenance work
This instantaneous water heater features an automatic air bubble protection to prevent it from inadvertently running dry. Nevertheless, the appliance must be vented before using it for the first time. Each time the appliance is emptied (e.g. after work on the plumbing system, if there is a risk of frost or following repair work), the appliance must be re-vented before it is used again.

1. Disconnect the instantaneous water heater from the mains (e.g. via deactivating the fuses).
2. Unscrew the jet regulator on the outlet fitting and open the cold water tap valve to rinse out the water pipe and avoid contaminating the appliance or the jet regulator.
3. Open and close the hot water tap until no more air emerges from the pipe and all air has been eliminated from the water heater.
4. Only then should you re-connect the power supply again (e.g. via activating the fuses) to the instantaneous water heater and screw the jet regulator back in.
5. The appliance activates the heater after approx. 10 seconds of continuous water flow.

Cleaning and maintenance

• Plastic surfaces and fittings should only be wiped with a damp cloth. Do not use abrasive or chlorine-based cleaning agents or solvents.
• For a good water supply, the outlet fittings (e.g. jet regulators and shower heads) should be unscrewed and cleaned at regular intervals. Every three years, the electrical and plumbing components should be inspected by an authorized professional in order to ensure proper functioning and operational safety at all times.

Troubleshooting and service

This instantaneous water heater was manufactured conscientiously and checked several times before delivery. Should malfunctions nevertheless occur, it is usually only due to a bagatelle. First attempt to switch the house fuses off and on again in order to reset the electronics. Next, try to remedy the problem with reference to the following table. In doing so, you will avoid the unnecessary expense of customer service assistance.

(Art. no. 36100)
The instant water heater can be installed by means of this mounting kit in the below situations. The power supply cable is coming out of the wall at any place from behind the unit, but the wall has unusual surface conditions, making it difficult for installing the water heater.
When using the RDX the protection class changes from IP25 to IP24.

Extension kit VDX

(Art. no. 34120) – RDX / RDX 3 is necessary! –
The instant water heater can be installed by means of this extension kit if the water pipes are coming displaced or exchanged out of the wall or if they are coming edge-wise on the wall to the unit. The power supply could come out of the wall at any place under the unit or the wiring could be installed surface-mounted.

Extension kit UDX

(Art. no. 34110) – RDX / RDX 3 is necessary! –
The instant water heater can be installed by means of this extension kit if the water connections are expiring above the unit. The power supply could come out of the wall at any place under the unit or the wiring could be installed surface-mounted.

Installing the wall bracket

Note: If you install this instantaneous water heater in exchange for a conventional instantaneous water heater, there is generally no need to drill holes for the wall bracket, in this case step 2 would not be necessary.
Thoroughly rinse the water supply pipes before installation to remove soiling from the pipes.

1. Using a 12 mm hexagon socket screw key, screw the screw-in nipples into the wall connections. The seals must be fully screwed into the thread. After tightening, the double nipples must protrude by 12 – 14 mm.
2. Hold the included mounting template on the wall and align it so that the holes in the template fit over the double nipples. Mark the drill holes according to the template and drill them using a 6 mm drill. Insert the included dowels.
3. Pull down the faceplate and unscrew the main hood screw to open the appliance.
4. Loosen the knurled nut to remove the wall bracket and screw the wall bracket to the wall. Offset tiling or uneven surfaces can be compensated by up to 30 mm with the aid of the spacers supplied. The spacers are fitted between the wall and the wall bracket.

Installing connection pieces

Note: Fasten the screw nuts with caution, to avoid damage to the valves or the piping system.

• As shown in the illustration, screw the cold water connection piece with the union nut and the ½ inch seal onto the cold water connection.
• Screw the hot water connection piece with the union nut and the ½ inch seal onto the hot water connection.
• Put the water flow limiter “D” into the hot water connection piece. The O-ring must be visible

Installing the appliance

The electrical power supply cable may be connected in the upper part or is surface mounted. Only in such case, first follow steps one through three according to the description “Electrical connection from above” in chapter “Electrical connection”.

1. Place the appliance on the heater bracket so that the threaded rod of the wall bracket fits in the corresponding hole of the appliance. If necessary, slight corrections are possible by carefully bending the threaded rod of the wall bracket. However, it must be possible to screw on the water connection pipes of the appliance without applying force.
2. Screw the plastic knurled nut onto the threaded rod of the wall bracket.
3. Screw the two ⅜ inch union nuts of the appliance‘s water connection pipes, each with the ⅜ inch seal, onto the fittings.
4. Open the water supply line to the unit and slowly open (position “open“) the shut-off valve (a) in the cold water connection piece. Check all connections for leaks.
5. Next, open and close the hot water tapping valve several times until no more air emerges from the line and all air has been eliminated from the instantaneous water heater.

Direct connection

Note:
Fasten the screw nuts with caution, to avoid damage to the valves or the piping system.

For direct connection, the two ½ inch screw-in nipples and the ½ inch seals must be screwed into the ½ inch union nuts of the hot-water and cold-water connectors. The two ½ inch caps of the side outlets of the hot-water and cold- water connectors must be removed and screwed onto the open end of the screw-in nipples. Put the water flow reducer “D” into the hot water connection piece. The hot-water and cold-water connectors must then be screwed into the ⅜ inch union nut of the appliance inlet and outlet pipe, together with the ⅜ inch seals. For direct connection, it may be advisable to mount the appliance at a distance as illustrated alongside, using the spacer sleeves supplied. The two fixing holes near the lower pipe connections are also to be professionally fixed with 6 mm dowels and screws. The flared end of the pipes must be screwed into the ½-inch side outlets of the hot-water and cold-water connectors with ½-inch union nuts and ½ inch seals. The holes required for the pipes must then be opened of the housing with the aid of a blunt implement. In case of direct connection please note: Put the strainer into the cold water connection!
