9.3. Preventive maintenance

Depending on usage, maintenance should be un-
dertaken by an authorised service engineer at least
once a year in order to prevent defects and failure of
operation. Authorised engineers are persons who due
to their skills and experience have sufficient knowl-
edge of the Hygiene Systems and are confident with
the state work safety regulations, accident preventing
regulations, lines and generally acknowledged techni-
cal regulations such as DIN-norms and VDE-provi-
sions. For your safety, this cleaning unit has been
manufactured according to all relevant regulations
valid in the EU and therefore it has been supplied with
the CE-marking. For further information, please refer
to the service department.

9.4. Rinsing the chemical supply/injector system

The chemical supply must always be
rinsed thoroughly after use.
Remains of detergents or disinfectants can clog the
injector so it needs to be rinsed or replaced.
The following procedure will clean the chemical sup-
ply for detergents and/or remains of disinfectants.
1. Remove User Pack, if any.
2. Hold the rinsing bottle with clean water tightly
against the suction opening (with User Pack) or
against the hose (without User Pack). Alternati-
vely, 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.
3. Activate the hose handle until clean water comes
out of the nozzle (approx. 30 seconds).
This procedure should be
followed both on the detergent
and the disinfectant side (if this is
installed).

9.5. Change of injector

1. Turn off power supply.
2. Turn off water and air supply.
3. Depressurise the system.
4. Unscrew and change injector. Beware of chemi-
cal residue.
5. Reconnect water, air supply and power supply.
