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 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
