The injector ST-160.2 is used for admixing liquid detergents to the volume ow 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 uids 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 ne lter with a recommended mesh size of 50 μm in the water supply
to the high-pressure cleaner. Install a suitable suction lter 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.

▪ The product is a pressure-retaining equipment according to the Pressure Equipment Directive 2014/68/EU. Due to its
parameters of use, it is subject to the scope of Article 4 / Clause 3 of this directive („sound engineering practice“) and thus
a declaration of conformity and CE marking are not admissible!
▪ The product must not be installed in devices which have to comply with the Pressure Equipment Directive 2014/68/EU!
▪ The component is a standard component in terms of the Machinery Directive 2006/42/EC!
For Your Safety
▪ Do not use the device if people not wearing protective equipment are in the immediate vicinity.
▪ Before starting work, check the high-pressure system (spray unit, hoses, screwing, etc.) for leakages and damage.
▪ Immediately stop operation if leakages or malfunctions occur.
▪ The suction hoses must not show any kinks
▪ Check the amount to be dosed
▪ Rinse the cleaned surfaces with clear water
▪ Read and comply with the safety data sheets of the detergent manufacturers
▪ Check if the chemical agents used are suitable for the surfaces you want to clean
Installation
Modication
▪ Switch off the high-pressure generator before performing any installati-
on works on the high-pressure system.
▪ Protect the high-pressure generator from being switched on acciden-
tally.
▪ Switch off the water supply.
▪ Make sure that the system sections and lines to be opened are depres-
surised.
▪ Seal the screw connections according to the application using an
appropriate sealant such as Teon tape or liquid sealants (refer to R+M
catalogue, Chapter 06, Adhesives and sealing materials)
▪ Fasten the support rmly to a vertical surface.
▪ Suspend the injector in the support without any play and tighten the
screw on the back.
▪ Connect the high-pressure hoses to the inlet and outlet
▪ Pay attention to the markings for the ow direction
▪ Fasten the suction hoses (9 mm ID) using hose clamps
Any kind of modication of the injector is not allowed!
Compressed air supply (optional)
For foaming with a passive foaming lance, an appropriate tting can be inserted in the lateral port. Place the container with the
chemical agent under the injector. (max. suction height 3 m)
(Optional) Connect the compressed air hose.

a) passive foamlance
Typical types of connection:
The air for foam generation is generated by the compressed-air generator (7)
b) active foam lance
The air for foam generation is
sucked in by the lance (1)
Setup: Lance with air injector:
Use the injector in the indicated pressure, volume ow, and temperature range, only. Before starting work, check the
values at the high-pressure generator and adjust them if required.
Foam quantity and concentration can be set using dosing inserts.
After studying the safety rules the use of the injector is very simple.
In order to clean the outside, use a lint-free cloth and do not use any aggressive cleaning agents.
Rinse the suction hoses using clear water to rinse the check valve.
After usage and prior to longer interruption of work (more than 1 hour), rinse the injector using clear water.
