Stop; Rinsing The Injector; Important; Service - Ecolab S400 Série Manuel D'entretien

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. 11).
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 Combifoamer 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
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 Combifoamer again after
it has been closed for a longer pe-
riod of time (holidays, and the like).

4.3 Rinsing the injector

IMPORTANT: The injector must
always be rinsed thoroughly
through after use. Remains of
topax detergent or topax disin-
fectants may clog the injector so
it needs to be rinsed or repla-
ced. The following procedure will
remove topax detergent and/or
remains of topax disinfectants from
the injector.
1. Remove User Pack, if any.
2. Turn handle on the right side of
the machine into foam po si ti on.
3. Hold the rinsing bottle with clean
water tightly against the suction
opening (with User Pack) or
against the hose (without User
Pack).
Alternatively, you can place a
User Pack with clean water in
the holder or - without User
Pack - place the hose in a
bucket of clean water.
4. Activate the spray handle until
clean water comes out of the
nozzle (approx. 30 seconds).
N.B. This procedure should be fol-
lowed both on the topax de ter gent
and the topax disinfectant side (if
this is installed).

5. Service

Only let authorized and qualifi ed
personnel carry out service.
Warning: The Combifoamer sy-
stem must only be serviced when
there is no voltage or pres su re on
the system:
1. Turn off the main switch.
2. Close the ball valve on the inlet
side.
3. Open a water tap.
