The injector ST-160.2 is used for admixing liquid detergents to the volume flow in the high-
and low-pressure range using the Venturi principle. The injector housing and the mounted
parts are made of stainless steel.
The injector includes a pair of nozzles. It features a connection for an air valve. For being
able to foam the admixed detergents, foam lances with and without air injector can be
used. For a good foaming result, the correct injector nozzles and inserts must be selected.
The injector is designed for suction of detergents and disinfectants. For details, please refer
to Directive 67/548/EEC.
The injector must only be used with fluids of Group I (e.g. water).
All safety instructions and regulations for high-pressure cleaners such as DIN EN 60335-
79-2 and DIN EN 1829-1 are to be complied with.
The operator must only use the injector if it is in a proper technical condition, without any
structural alterations, as intended, being aware of safety and hazards, and complying with
this User Manual. Only adults familiar with the use of high-pressure cleaners are authorised
to use the injector.
The injector must not be operated using abrasive materials. In order to avoid damage to
the injector, install a fine filter with a recommended mesh size of 50 μm in the water supply
to the high-pressure cleaner. Install a suitable suction filter in the chemical agent hose.
Also comply with the operating instructions of the devices and accessories connected to
the injector and the regulations applying to the detergents.
