Instantaneous water heater
Assemble the instantaneous water heater as shown in the illustrations. Observe the information in the text.
**** Safety information
- The instantaneous water heater must only be connected and started up by an authorised technician.
- The statutory regulations of the respective country, as well as those of the local electricity and water suppliers must be adhered to.
- The instantaneous water heater is an appliance of protection class I and must be connected to the protective earth conductor.
- The unit have to be connected durably to the mains electricity supply via an all pole disconnecting device with contact gap must be at least 3 mm.
- The instantaneous water heater is suitable for enclosed (pressurised) operation only.
- The tap fittings must be permitted for operation with enclosed (pressurised) instantaneous water heaters.
- The instantaneous water heater must only be connected to a cold-water pipe.
- The instantaneous water heater is suitable for connection to DVGW-tested plastic pipes.
- The instantaneous water heater must only be installed in a frost-free room.
- Prior to installation, the electric connecting cable must be disconnected from the mains voltage and the water supply cut off!
- Only connect the electric supply after the water supply.
- When making holes in the rear panel, only make the number of holes required for installation. If the appliance is reinstalled, any holes that are not used must be made watertight.
- Live components must not be touched subsequent to installation.
Assembly
Unpacking / removing the housing cover
- Unpack the appliance and check for transportation damage.
- Dispose of the packaging and, where applicable, the old appliance, in an environmentally conscious manner.
Preparation for assembly
Wall-mounted assembly
- The instantaneous water heater must be fitted securely to the wall. If required, secure the appliance using the lower adjusting screws.
- The distance from the wall is variable. This allows you to compensate for any unevenness in the wall surface.
- The sleeve in the rear panel must fit tightly round the connection cable. If the sleeve is damaged during installation, the holes must be sealed water-tight.
Water supply
- The flow-through heater must be vented. Open the warm water tap completely and allow to flow through for one minute.
Electric supply
- The mains connection can either be mounted above or below. At least 40 mm of the connecting cord’s insulating jacket must be clamped inside the appliance.
Startup
- For low water line pressure, remove the flow limiter (see Supplementary Information A).
- Instruct the user with regard to the operation of the instantaneous water heater.
- Separate the required language version from the rest of the operating instructions. This can be kept in the swingout control panel of the instantaneous water heater.
Additional information
If the flow-through heater does not achieve adequate flow as a result of water
line pressure that is too low in your house installation, remove the flow
limiter.
Priority circuit for the combination with electro storage heating units: For
operation with the priority circuit, a special load reducing relay (special
accessory) is required. Other already existing load reducing relays with the
exception of electronic load reducing relays could cause malfunctions.
