¦ In order to meet the current safety requirements, an all-pole disconnecting device must be present on the installation side. The contact gap must be at least 3 mm. ¦ The continuous-flow heater is suitable for enclosed (pressurized) operation only. ¦ The tap fittings must be permitted for operation with enclosed (pressurized) continuous-flow heaters. ¦ The continuous-flow heater must only be connected to a cold-water pipe. ¦ The continuous-flow heater is suitable for connection to DVGW-tested plastic pipes. ¦ The continuous-flow heater must only be installed in a frost-free room. ¦ Prior to installation, the electric connecting cord 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 wall, 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. Mounting I. 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. II. Preparation for assembly III. Wall-mounted assembly ¦ The continuous-flow heater must be fitted securely to the wall. Fasten the heater by means of the enclosed screws and rawl plugs. ¦ The adjustable screws can be used to compensate for any unevenness of the wall's surface. IV. Water supply ¦ The flow-through heater must be vented. Open the warm water tap completely and allow to flow through for one minute. V. Electric supply ¦ For appliance DE1UF24, the electrical supply clamp can also be mounted underneath. For appliances DE1UF18 and DE1UF21, special accessory BZ45Z20 is available for this purpose. At least 20 mm of the connecting cord’s insulating jacket must be clamped inside the appliance. VI. Startup ¦ For low water line pressure, remove the flow limiter (see Supplementary Information A). ¦ Instruct the user with regard to the operation of the continuous-flow heater. Additional information A B 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 electrostorage heating units: For operation with the priority circuit, a special load reducing relay BZ 45L20 (special accessory) is required. Other already existing load reducing relays with the exception of electronic load reducing relays could cause malfunctions.
