6 Installation

By the operator of the unit

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

must

have flexible,

have flexible, i.e. not rigid, piping.

A 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

(not at a residual hardness of

< 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 Multiblock/GIT Module and for
connection set DN 32/32.
The univalve block 1

“ order no.: 11822 can also be used for Rondomat

6 models.

Units 6 and 10 only

Units 6 and 10 are delivered empty and in unassembled form.

1. Position softening columns (1+2

1+2

1+2) in a suitable location (see installation

diagram), and remove the central pipes. Note!

Note!

Note! Do not mix up 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 an alignment.
There is a counter piece at the bottom of the softener column. Place the
central column with the distributor nozzle alignment downwards on the
counter piece in the softener column. 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.

Disinfectant solution preparation:

6 g powder for 10 liters of water

Safety note!

Safety note! Wear disposable gloves when preparing and flushing.

4. Clean softening column upper sections and threads of resin. Remove

Remove

the protective caps from the middle pipes. Do not pull the pipes upwards.

5. Smear O-rings with high-quality grease (e.g. Vaseline), and screw the
control valve (3

3) and the adapter (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 control valve

and adapter and secure each one with two support clamps (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.

Connect the unit to the local water-supply network

Connect the unit to the local water-supply network
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) into the tapered opening of the brine hose connection

(16

16) and tighten the coupling ring.

Secure the flushing-water hose (16 x 3) to the flushing-water connection
(10

10) using hose clamps. Route the hose with a natural incline to the sewage

system connection and secure against sudden pressure-induced movement.

Fasten a hose (13 x 2) around the overflow (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:

Please note: The flushing water and overflow 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).
