Installing the wall brack et (flush-mounted):
1. Thoroughly rinse the water supply pipes before installation to remove soil-
ing from the pipes.
2. Using a 12 mm hexagon socket screw key, screw the screw-in nipple into
the wall connector. After tightening, the double nipple must protrude by
12 mm.
3. Carefully seal the hot water connection pipe with a little P.T.F.E. Tape and
screwed it into the wall connection. Mount the cold water connector piece
including the 1/2“ seal.
4. Hold the unit on the wall and align it so that the water connectors of the
unit fit over the connections of the wall. Mark the drill holes and drill them
using a 6 mm drill.
5. Mount the unit to the wall and connect the water supply of the unit,
together with the 3/8“ seals.
6. Open the water supply line to the unit and slowly open the shut-off valve
in the cold water connection piece (10 a) (Pos.I). Check all connections for
leaks.
7. Next, open and close the hot water tapping valve several times until no
more air emerges from the line and all air has been eliminated from the
instantaneous water heater.
If you install the instantaneous water heater CRX 9 instead of a conventional instantaneous water heater, there is gener-
ally no need to drill holes for the wall holder. In this case, you only need to screw in the double nipples as described in 2.
and to secure the wall bracket.
