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.

Introduction

CAUTION
Indicates a potentially hazardous situation that may result in minor or moderate
injury.

Important Note: Indicates a situation which, if not avoided, may cause damage to the

instrument. Information that requires special emphasis.

Note: Information that supplements points in the main text.

Precautionary Labels

Read all labels and tags attached to the instrument. Personal injury or damage to the
instrument could occur if not observed. A symbol, if noted on the instrument, will be
included with a danger or caution statement in the manual.

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.

Cleaning Unit

The manufacturer recommends using the High Output Airblast Cleaning System for the
compressed air supply; this is a compressor in a weather-proof plastic housing. This
complete system is operated through a relay in the sc100/sc1000 controller.

DANGER
Only qualified personnel should conduct the tasks described in this instruction
sheet.

CAUTION
Make sure the cleaning unit is disconnected from the compressed air during
installation and service work.

When using an external compressor or an existing compressed air system, a suitable
valve is required (and, if necessary, a pressure reducer) and can be configured through a
relay on the sc100/sc1000 controller.

Figure 1 Principle of operation of the cleaning unit

Unpacking the instrument

Verify that all items (refer to Figure 3 on page 3) are included. If any items are missing or
damaged, contact the manufacturer or a sales representative.

Do not send the items without contacting the manufacturer or a sales representative.

Note: Retain the original packaging materials. Instruments returned for service should be shipped in
the original packaging material to protect against damage during transportation.
