Installing connection pieces
To open the appliance hood, take off the faceplate
and unscrew the main hood screw.
When replacing an appliance, the electrical power
supply cable may be connected in the upper part.
Only in such case, follow the instructions “Electrical
connection from above”.
Place the appliance on the heater bracket so that
the threaded rod of the wall bracket fits in the
provided hole of the appliance. If necessary, slight
corrections are possible by carefully bending the
threaded rod of the wall bracket. However, it must be
possible to screw on the water connection pipes of
the appliance without applying force.
Screw the two ⅜” union nuts of the appliance’s
water connection pipes, each with the ⅜” seal, onto
the fittings.
Screw the plastic knurled nut onto the threaded rod
of the wall bracket.
Open the water supply line to the unit and slowly
open (position “open”) the shut-off valve (a) in the
cold water connection piece. Check all connections
for leaks.
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.
As shown in the illustration, screw the cold water
connection piece with the union nut and the ½” seal
onto the cold water connection.
Screw the hot water connection piece with the union
nut and the ½” seal onto the hot water connection.

Note
Fasten the screw nuts with caution, to avoid
damage to the valves or the piping system.
Installing the appliance
For direct connection, the two ½” screw-in nipples and
the ½” seals must be screwed into the ½” union nuts
of the hot-water and cold-water connectors. The two
½” 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. The hot-water
and cold-water connectors must then be screwed into
the
3
/
8
” union nut of the appliance and delivery pipe,
together with the
3
/
8
” seals.
For direct connection, it is advisable to mount the
appliance at a distance as illustrated alongside, using
the spacer sleeves supplied. It should therefore be
noted that the two fixing holes near the lower pipe
connections are also used.
The flared end of the pipes must be screwed into
the ½” side outlets of the hot-water and cold-water
connectors with ½” union nuts and ½” seals. The
holes required for the pipes must then be broken out of
the housing with the aid of a blunt implement.
In case of direct connection please note:
Put the strainer into the cold water connection!
Note
Fasten the screw nuts with caution, to avoid
damage to the valves or the piping system.
