2. Maintenance

The main stations and satellites
are maintenance-free. However,
the fi lters should be cleaned at
regular intervals (approx. 1-3
months) depending on the calcare-
ous content of the water.

2.1 Filter

(Fig. 12)
1. Press "0" on the control panel
to stop the main station.
2. Close the ball valve for the inlet
water.
3. Open a tap to release the sys-
tem of pressure.
4. Remove the fi lter and place it in
a scale loosening solvent until
the calcerous substance has
been dissolved.
5. Rinse the clean fi lter thoroughly
and remount.
2.2 Long stops
If long production stops are plan-
ned (more than 6 months) and
the pump is emptied of water, it
is recommended that the pump is
secured as follows:
1. Remove the coupling guard.
2. Spray a couple of drops of silico-
ne oil on the shaft between the
pump head and the coupling.
Carefully follow the instructions
given in the manual provided by
the pump supplier.

3. Start

N.B. Do not start the pump until
it has been vented and fi lled with
water.
N.B. Check that the fl ow switch is
correctly fi tted, see Fig. 13. The
fl ow switch should be placed paral-
lel to the pipe so that the cable
emerges in the direction of fl ow.

3.1 New units

To prevent problems when starting
a new unit, the system should be
rinsed thoroughly through and
vented.
Venting of pipe system
1. Turn on the water supply to rinse
and vent the entire system. If
satellites are installed, open the
tap furthest away until no air or
dirt comes out. Then rinse and
vent the next tap and continue
until the tap closest to you has
been rinsed and vented.
2. Mount satellites, if any.
Venting of pump
3. Loosen the drain plug (A, Fig.
14) one or two turns until water
and air come out.
N.B. Never loosen the drain plug
while the pump is running. This
can damage the gasket.

4. Retighten the drain plug.
5. Start the pump so that the last
air pockets can be pressed to
the top of the pump.
At the same time, check that
the discharge direction of the
B
pump is correct. See the ar-
rows on top of the motor.
6. Stop the pump.
7. Loosen the drain plug one or
two turns again until only water
17467
comes out.
8. Retighten the drain plug.
The main station is now ready for
ope ra ti on. Press "I" on the control
panel.

4. Daily operation

4.1 Start
1. Turn on the water supply which
must be above the main sta ti on.
2. Open the air supply placed
17465
inside the main station (see A,
Fig. 15).

3. Press "I" on the control panel to
start.

4.2 Stop

Main station
1. Press "0" on the control panel
to stop.
2. Turn off the water supply.
3. Close the air supply (A, Fig. 15).
N.B. It is important to interrupt the
water and air supplies when the
mac hi ne is left after use because:
• If the air supply is open when
the main station is not in use,
air may seep into the water
pipe. If this is the case the
system may have to be vented
again.
• The water separator which is
17526
part of the air regulator is only
to be emptied when the air is
shut off.
It may be necessary to vent the
pipes and the main station again
after it has been closed for a lon-
ger period of time (holidays, and
the like).
