Introduction

The cleaning unit is designed for automatically cleaning the sensor cartridge membranes

(refer to Figure 1 on page 2). The streamlined design of the cleaning unit minimises the

points where interferences could occur. Refer to Figure 3 on page 3 for the cleaning unit

dimensions.

The cleaning unit is exactly matched to the sensors so that the sensor cartridge

membranes are kept clean even in difficult inlet applications. The cleaning head requires

compressed air (2 to 3.5 bar (29.01 to 50.76 psi) maximum) that is produced by a

compressor or supplied from an existing compressed air system.

Important Note: The compressed air must be oil free.

Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after

12 August of 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC),

European electrical equipment users must now return old or end-of life equipment to the Producer for disposal at no

charge to the user.

Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return

end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal.
