6. Installation
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 brack-
et, 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 at least 12mm.
2. Hold the included mounting template on the wall and align it so that the holes in
the template fit over the connections. Mark the drill holes according to the template
and drill them using a 6 mm drill. Insert the included dowels.
3. Screw in the wall bracket. 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 the wall bracket
Note: Fasten the screw nuts with caution, to avoid damage to the valves or the
piping system.
1. As shown in the illustration, screw the cold water connection piece with the union
