The dispenser pump hoses are subject to severe wear and tear (aggressive
agents) and should therefore be replaced at least once per year; see Replacing
the Dispenser Pump Hose Complete With Pump Cap, 091 4.2. To suit the various
agents in use several different hoses are available. A conversion kit contains a
dispenser pump cap with a pre-installed hose.

A Fill-level sensor,openfor full dispensing containers!
B Float switch (flow monitoring),closedfor liquid media!
A spring-loaded float switch for flow monitoring was integrated into K-series DOS
modules, in addition to G-series DOS modules. After flow, this spring pushes the
piston of the float switch back into its initial position. It is switched in parallel to the
fill-level sensor within the module housing and is therefore pin-compatible to the...

3 Fault Repair
3.1 Swelling of Hose Material
Cause
To ensure that elastomers are treated as gently as possible, disinfecting, alkaline
detergents with a high active chlorine content should not be used at temperatures
above 176°F/80°C. In particular, liquid agents with tensides and disinfectants can
lead to large variations in the volume capacity of dispenser pumps (usually due to
swelling of the hose material).
Remedy
AReplace the hoses.
