1 Introduction

1.1 Warnings, cautions and notes

Read this manual and ensure that you fully understand its content before you attempt

to install, use or maintain the analyser. Important safety information is highlighted in

this manual as WARNINGS and CAUTIONS and NOTES, which are used as follows

WARNING

Warnings highlight specific hazards which, if not taken into account,

may result in personal injury or death.

CAUTION

Cautions highlight hazards which, if not taken into account, can result in damage to

the analyser or to other equipment or property.

NOTES

Alerts the user to pertinent facts and conditions.

1.2 Scope of this manual

This manual covers the installation of the SERVOTOUGH FluegasExact Combustion

Gas Analyser, abbreviated to "the analyser" in the remainder of this manual, and the

various options that are available.

Refer to Section 8 of this manual for the latest technical specification.

Addresses for technical assistance and spares are given on the rear cover.

A QuickStart Manual is available, part number 02700003D.

A Service Manual is available for use by qualified personnel, part number 02700002D.

1.3 General safety information

WARNING

You must install and use the analyser in accordance with the

requirements of this section and subsequent sections of the manual. If

you do not, people may be injured, the protection facilities

incorporated into the design of the analyser may not operate as

intended, sample gas measurements may not be accurate, or the

analyser may be damaged.

The analyser must be installed by a suitably skilled and competent

technician or engineer.

You must not modify the analyser in any way (either mechanically or

electrically). If you do, the certification of the analyser will be

invalidated and it may not operate safely.

The sensor head is heated and may be attached to a hot flue.

Consequently, the temperature of the sensor head may exceed 100°C.

To avoid a risk of burns, appropriate protective equipment must be

used when handling the sensor head, even when it is unpowered.

The sensor head aspirator supply must not contain flammable gases.

The sensor head is not suitable for use in hazardous areas / locations

without the use of appropriate safety purge equipment.

Servomex 2700 EU2/UK2/FM2/CS2/NA2 approved control units must

be used if the installation is in a Zone 2 / Division 2 hazardous area /

location.

Flanges and flange adaptors supplied by Servomex DO NOT conform

to ANSI or any other Standards body and must only be used in

Servomex specified applications with process pressure not greater

than 0.34 barg (5 psig).

CAUTION

The analyser may fail if used with sample streams containing substances not

compatible with those listed in Section 8.6 Materials in contact with the sample.

The combustibles measurement is not promoted or recommended as a primary

safety measurement, e.g. for use in electrostatic precipitator (ESP) protection or

coal mill applications.
