Installation
Installation is not permitted
­ Hot water pipes
­ Circulation pipes
­ Non­drinking water pipes
Danger of crushing
The device has an electrically operated shut­off.
Never insert objects or body parts into the pipe
openings when voltage is present through the power
supply unit or the emergency power batteries are
inserted.
Malfunction possible due to incorrect
installation position
"Overhead" installation, i.e. installation with the display
facing downwards, is not permitted.
The following prerequisites must be met:
­ The mains pressure must not exceed 1,0 MPa
(10 bar). In the event of a higher mains pressure, the
RE.GUARD water control must only be installed after a
pressure reducer set to a maximum of 1,0 MPa
(10 bar).
­ If drinking water consumers are installed in the
building which must not be shut off by the RE.GUARD
water control system, their supply lines must be
branched off beforehand. These could be:
­ Any type of extinguishing water system, e.g. wall
hydrant for independent fire fighting, burn­back
protection for solid fuel boilers, sprinkler system
­ Any type of emergency cooling device such as a
thermal discharge safety device
­ Any type of make­up device for relevant systems
which, if they cease to function, would cause more
damage than leaking water, e.g. the cooling system
of a server room or the heating system for a
greenhouse
Install the device correctly according to the flow
direction (observe the flow direction arrows on
the device).
in:
Before installing the RE.GUARD water control, check that the
drinking water installation has sufficient dimensions.
If agents are added to drinking water (e.g. for hardness
stabilisation) or if softening or demineralisation measures are
taken, please contact REHAU.
The RE.GUARD water control should preferably be installed
immediately after the installation section of the domestic
water meter in the drinking water installation, i.e. directly after
the shut­off device with backflow preventer, directly after the
water meter.
Basically, no inlet section is required for the installation of the
RE.GUARD water control directly after the water meter or
other straight fitting.
For installation directly after a deflection (e.g. 90° bend/
angle), an inlet section of approx. 5 x DN is recommended in
order to improve the measurement result for flow and
pressure.
For operation and maintenance above the RE.GUARD display,
maintain a clearance of at least 20 cm so that the upper part
can be removed without risk of damage.
In the shell construction phase, the RE.GUARD water control
can be replaced by a water meter fitting of length 190 mm
with threaded connections G1" male thread (to be procured
on site).
For the reliable detection of leakage events, in
particular for the detection of microleaks, it is
necessary for all installed non­return valves (after the
domestic water meter, after the branch for water
provision, at the withdrawal fittings) to work correctly.
Ensure their function by regular maintenance.
Only use suitable flat gaskets suitable for
drinking water.
Do not use the housing or other parts of the
RE.GUARD water control as counterholds when
tightening threaded connections.
After installation, flush the drinking water
installation in accordance with national
regulations and check all newly made threaded
connections for leaks. If leak detection agents are used,
the manufacturer of the agent must be consulted in
advance as to the extent to which the materials of the
RE.GUARD water control can be influenced.
Only use leak detectors suitable for drinking water.
