5. Installation prerequisites

Local installation instructions, general guidelines
(e.g. WVU, EVU, VDE, DIN or ÖNORM, DVGW or
ÖVGW.), hygiene conditions and technical data
must be observed. The installation area must be
frost-proof and preferably horizontal. Note that a
DIN DVGW / ÖVGW tested filter (filter depth 90 μm)
must be installed upstream of the softening or limes-
cale protection system so that the pipework is free
from hazardous chips, hemp or similar contaminants.
In addition, the section from the water meter to 1m
downstream of the multiblock X must be fully pro-
tected against corrosion using components of the
HydroMODUL domestic water distribution system,
all manufactured from the same corrosion-resistant
materials. Please ensure that the specified nominal
10 bar pressure is not exceeded. We recommend
connecting a pressure reducer (DR module or DR
connection module) from a minimum supply pres-
sure of 4 bar to avoid an excessively high load on
both the equipment and the entire domestic water
installation.
6. Installation
Basically, installation is carried out in the cold water
pipe between the shut-off valves (which must be
closed prior to installation), and ideally behind the
water metering system and filter (fig. 3). The easiest
way to install it is on a HydroMODUL distribution rou-
te (fig. 5), in which case the supplied screw-in part
and connection screw must not be used.
In a conventional installation (fig. 1) the screw-in part
is mounted on the input side and the connection
screw on the output side of the pipework. Note the
flow direction arrows here. Check that the system
has the correct electricity and water installation (in
accordance with DIN 1988, part 100). All connections
and pipework links must be re-examined for leaks
prior to commissioning.

7. Operation

To interrupt the operation
Turn the handwheel on the multiblock clockwise to
the lower stop (arrow mark on the handwheel: "Z"
for "closed") – the supply to the device is shut off,
the multiblock is in the "bypass" operating mode.
To resume the operation
Turn the handwheel on the multiblock anticlock-
wise to the upper stop (see the arrow mark on the
handwheel: "A" for open). The water supply is then
activated and the equipment supplies the rest of the
domestic water system.

8. Maintenance

Each technical installation requires regular mainte-
nance. We recommend the system is tested by a
BWT professional during routine inspections of the
equipment.
