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).
