Long Stops; New System; Daily Operation - Ecolab S4000 Serie Manual De Servicio

2. Maintenance
Main stations and satellites are
maintenance-free. However, fi lters
must be cleaned at suitable inter-
vals (approx. 1 - 3 months) depen-
ding on the content of cal ci um and
impurities in the water.
2.1 Filter
(Fig. 14)
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 sy-
stem of pressure.
4. Remove the fi lter and place it
in a lime solvent until the calce-
rous substance is 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 be
safeguarded as follows:
1. Remove the coupling safety
guard.
2. Spray a couple of drops of sili-
cone oil onto the axle between
the top section and the coupling.
Carefully follow the instructions
gi ven in the manual provided by
the pump supplier.
3. Start
N.B. The pump should be bled and
fi lled with water before start.
N.B. Check that the fl ow switch is
correctly fi tted, see fi g. 15.

The fl ow switch should be placed
pa ral lel to the pipe so the cable
emerges in the di rect ion of fl ow.

3.1 New system

In order to ensure a problem-free
start of a new system, the pipe
system must be fl ushed and bled:
Bleeding the pipe system
1. Turn on the water supply to
rinse and bleed the entire sy-
stem. If satellites are installed,
open the tap furthest away until
no air or dirt comes out. Then
rinse and bleed the next tap and
continue until the tap closest to
you has been rinsed and bled.
2. Mount satellites, if any.
Bleeding the pump
3. Loosen the relief plug (A, fi g. 16)
1-2 revolutions until water and
air begin to fl ow out.
NB: Never loosen the relief plug
while the pump is running as
this may damage the packing.

7. Loosen the relief plug 1-2
re vo lu ti ons again and bleed the
system until only water fl ows
out.

start.
Satellite
1. Check that the main station has
started
2. Turn on the water supply above
