Fit shut-off valves up- and downstream of the unit. The unit can be connected
to the water-supply network with commercially available fittings and stop
valves.
We recommend that you connect the unit using flexible hoses, e.g. with the
connection set. Softening units with more than 90 litres of resin per bottle
must have flexible, must have flexible, must have flexible, i.e. not rigid, piping. must have flexible, must have flexible,
An E multiblock module can only be installed on Rondomat Duo 2 and 3
models if blended water is to be used (not at a residual hardness of
< 0.1 °d) < 0.1 °d) < 0.1 °d). < 0.1 °d) < 0.1 °d)
If the residual hardness is less than 0.1° d, a GIT multiblock module can be
used.
Please note that there is a separate manual for the E Multiblock/GIT Module
and for connection set DN 32/32.

1. Position softening columns (1+2
tion diagram), and remove the central pipes. Note!
central pipes! The length of the central pipe with the distributor is
designed precisely for the softening columns.
Make sure that the softening columns are empty and clean.
2. The distributor at the lower end of the central pipe has a recess.
There is a mortice at the bottom of the softener column. Place the
central column with the distributor nozzle downwards on the mortice
in the softener column. The mortice secures the distributor of the
central pipe. Seal the pipes using protective caps.

3. Put the filling cone in place and pour in the correct quantity of coarse
chip, followed by fine chip and resin, making sure that they are evenly
distributed around the central pipe. Flush in the last 1 - 2 sacks of ion
exchanger with a disinfectant solution.

5. Smear O-rings with high-quality grease (e.g. Vaseline), and screw
the control valve (3 3 3 3 3 ) and the adapter (4 4 4 4 4 ) on the softening columns,
ensuring a tight fit. The central pipes must engage in the openings
sealed by the O-rings on the control valve and adapter respectively.
Turn the softening column into the connecting position. Pull the O-rings
onto the reinforced hoses (17 17). Insert the reinforced hoses into the 17 17 17
control valve and adapter and secure each one with two support clamps
18 18
(18 18 18).
Secure the controller mounting-plate
Unscrew two screws on the control valve (see below) and secure the
mounting plate using these screws. Screw the Soft-Control controller
and the transformer onto the mounting plate.

The local hard and soft water pipes should be connected to the input and
output pipes on the unit respectively.
Insert the brine hose (9 9 9 9 9 ) into the tapered opening of the brine hose
connection (16 16 16 16 16) and tighten the coupling ring.
Secure the flushing-water hose (16 x 3) to the flushing-water connec-
tion (10 10 10 10 10) using hose clamps. Route the hose with a natural incline to the
sewage system connection and secure against sudden pressure-in-
duced movement.
Note! Note! Note! Note! Note!
If the flushing-water hose is routed above the total height of the unit
(max. 1.5 m), the admission pressure on the injector must be reset by
our after sales service staff when the unit is started.
Fasten a hose (13 x 2) around the overflow (8 8 8 8 8 ) of the brine container.
Secure it with hose clamps and route it with an incline to the sewage
system connection (drain). There should be no constriction of the cross
section of either hose.
Please note: According to DIN 1988, the flushing water and overflow Please note: Please note:
Please note: Please note:
hoses must be routed separately and connected to the sewage water
system at least 20 mm above the highest waste water level (unimpeded
drainage).
Make electrical connections (see terminal connection diagram; 8-wire
valve block, numbered cables; salt low, water meter, transformer).
