Feed-in water
This system is not intended to be used for treating
water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
the system.
The total dissolved iron and manganese may not
exceed 0.1 mg/l. The hard water to be fed into the
unit must always be free of air bubbles. If necessary,
an de-airation device must be installed.
The necessary operating pressure must always be
guaranteed.
A minimum operating pressure is required for the
unit to function (see technical data).
The maximum operating pressure of the unit must
not be exceeded (see technical data). If the network
pressure is higher, then a pressure reducer must be
installed upstream of the unit.
In the case of pressure deviations and pressure
surges, the total of the pressure surge and standing
pressure must not exceed the nominal pressure,
meaning the positive pressure surge must not ex-
ceed 200 kPa and the negative pressure surge must
not fall beneath 50 % of the adjusted flow pressure.
Continuous operation of the softening unit with water
containing chlorine or chlorine dioxide is possible if
the concentration of free chlorine / chlorine dioxide
does not exceed 0.5 mg/l.
However, continuous operation with water con-
taining chlorine/chlorine dioxide causes the ion
exchanger resin to age prematurely. A softening
unit reduces the concentration of free chlorine and
chlorine dioxide. In other words, the concentration
in the outflow of a softening unit is generally consi
-
derably lower than in the inflow.

Installation
The pipe network must be flushed before the unit
is installed.
Use corrosion-resistant pipe materials for installati-
on. Observe corrosion-causing chemical properties
in the combination of different pipes (mixed instal
-
lation), even in the direction of the flow upstream
of the softening unit.
The hose attached to the overflow of the brine
container and flushing water hose must be routed
at an incline to the sewage system or connected
to a pump.
The flushing water hose and the overflow hose
must be secured at the specified distance from the
highest possible waste water level to the sewage
connection (distance greater than the diameter of
the waste pipe).
If flushing water is fed into a pump, it must be desig
-
ned for a water quantity of at least 2 m
3
/h or 35 l/min.
If the pump is used for other units simultaneously,
it must be sized larger by a factor of their water
output quantities.
The pump must be salt-water resistant.
To assist in connecting to the pipework, the following
fitting can be used:
This is a 32 mm FI x 20 mm FI BSP reducing
union set.
Reece Product Code
1906945
This fitting will not only assist in adapting to smaller
tube size pipework, from the 32 mm MI Bewamat
valve, but also assist where installation space is a
hindrance.
20 mm MI elbow / reducing elbow fittings, will also
screw straight into this union set. Contact your local
Reece branch for further information.
