5. 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 3/8 inch union nut of the appliance inlet 

and outlet pipe, together with the 3/8 inch seals. 
For direct connection, it may be advisable to mount the appliance at a distance as illus-

trated 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-wa-

ter 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.

Note: In case of direct connection, put the strainer into the cold water connection!

Load Shedding Relay

If further three-phase appliances are connected, a load shedding relay designed for 

electronic instantaneous water heaters (Art no. 82250) can be connected to phase 

conductor L2. 
To avoid possible jitter of the load shedding relay caused by low power consumption 

(low temperature set point and low water flow rate) the “Load-shedding-mode” can be 

activated as followed:

•  Disconnect the appliance from the power supply (e.g. by switching of the fuses)
•  Take the jumper off the power electronics and change to position “1” (see picture).
•  Put the appliance into operation again

Structural Prerequisites

•  The appliance must be installed via a permanent connection. Heater must be 

earthed!

•  The electric wiring should not be injured. After mounting, the wiring must not be 

direct accessible.

•  An all-pole disconnecting device (e.g. via fuses) with a contact opening width of at 

least 3 mm per pole should be provided at the installation end. 

•  To protect the appliance, a fuse element with trigger characteristic C must be fitted 

with a tripping current commensurate with the nominal current of the appliance.

Note: Installation work must only be conducted by an 

authorised professional.

Please observe:
•  e.g. VDE 0100
•  The installation must comply with current IEC and national local regulations or any 

particular regulations, specified by the local electricity supply company

•  The rating plate and technical specifications
•  The appliance must be earthed!
