2.0 SAFETY INFORMATION
2.1 ENVIRONMENTAL PARAMETERS
The STS Siloxane Monitor operates from a 110V mains supply, the instrument case
should not therefore be opened without having first isolated the power supply and disconnected
the kettle lead form the rear of the instrument. The high voltage section of the instrument is
protected by clear cover – this should not be removed unless necessary- having followed the above
instructions. FAILURE TO ISOLATE THE SUPPLY MAY RESULT IN ELE TRI SHO K.
It is the responsibility of the owner of the instrument to complete a risk assessment on its
installation, operation and servicing before being commissioned for use.
Inhalation of gases may be harmful to health, it is the responsibility of the operator to ensure they
have adequate training in the safety aspects of handling biogas/landfill gas and that they follow
appropriate procedures at all times. The vent/exhaust form the instrument must be piped to an
area designated safe to discharge to atmosphere- a flame arrestor may be required to be fitted.
Installation and Maintenance of the unit should only be carried out by suitably trained personnel
according to the applicable code of practice.
Maintenance should be carried out only using STS approved replacement parts and components –
use of substitutes will invalidate the warranty and may be hazardous to both operator and
instrument.
No alterations should be made to the instrument or its ancillary components.
Failure to comply with the instructions in this manual could result in injury to the user.
The instrument captures fuel gas any work associated with the instrument must be carried out by a
class of person competent and certified to do so.
Should at any point you require additional help or information on the safe installation or
use of the system please contact STS at: sales@safetrainingsystems.com or +44 (0) 1344 483563

•The Siloxane Monitor is not weatherproof and must be housed in a suitable kiosk or cabinet
if sited outside of a building
•If siting inside a building consideration should be given to the local conditions as regards to
dust, moisture and ventilation the Monitor is available supplied in a 19” rack case suitable
for indoor use with inbuilt thermostatically controlled extraction fans.
•The monitor is suitable for use between 5 and 45 without additional cooling/heating
required.
•Gas supply to the instrument should be at a minimum of 200mbar
•Adequate ventilation/air passage around the instrument should be provided.

3.0 OVERVIEW
3.1 INSTRUMENT DESIGN
3.1.1 INSTRUMENT S HEMATI
3.1.2 INSTRUMENT
Biogas is supplied to the instrument via a sampling system that removes water and particulates.
The instrument has been assessed in accordance with IGE SR 25 for potential leakage risk and
development of explosive atmospheric conditions internal to the instrument.

th
August 2017, STS Instruments Ltd, Installation ManualInstallation Manual Jan 2018
The instrument is designed to be installed down stream of a boosted gas supply.
The design of the instrument is such that failure of any internal joint inside the instrument cannot
give rise to an explosive atmosphere inside the instrument. Nevertheless prior to energising the
instrument a tightness test including the instrument shall be performed. This test shall be in
accordance with IGE UP1B and include the instrument.
(35mb for 1 minute temperature stabilisation followed by a 2 minute tightness test). The tightness
test shall have no pressure drop.
The installer shall perform a let-by test of the upstream bio-gas section isolation valve. The valve
shall be closed and the pressure reduced to approx 50% of the operating pressure and tested for
let-by for a period of 1 minute. If a rise in pressure of more than the gauge readable movement
(GRM) is observed the isolation valve shall be replaced.
If during the tightness test there is a pressure drop then the instrument shall be disconnected and
the installation sealed with the appropriate fitting, the case shall be removed and the internal
elements inspected for damage. If the leakage cannot be corrected the instrument shall be
removed for factory inspection and correction.
Any work on the instrument shall be undertaken by a suitably competent person approved for the
time being by the Health and Safety Executive.

3.2.1.2 INTERMEDIATE AND POST FILTER SAMPLE LINE S HEMATI S
3.2.2 SAMPLING SYSTEM
Biogas is sampled by taking samples of raw and or treated biogas from the main gas pipework used
to supply the biogas engine.
The sampling arrangement may be single port or multiport, so that the instrument is capable of
sampling raw untreated gas, partially treated gas and treated gas prior to combustion in the biogas
engine.
The sample lines should be connected into purge points by means of a reducing T and additional
isolation valve. The sample points shall be installed so that the purge point on the main gas
pipeline remains usable for nitrogen or air purging.
The sample points shall be provided with individual isolation and test points to enable sample line
isolation and to enable sample line purging.
Sample pipelines shall be mounted on robust racking.
Sample lines shall be provided with trace heating and lagging from the instrument to the sample
point. Electrical power for the trace heating shall be taken from the instrument supply.
The sample line pressure shall be tested and a regulator selected to ensure an instrument sampling
system pressure does not exceed 35mb. If the system pressure has been declared by the operator
the installer shall nevertheless verify the site system pressure and selected regulator and ensure
that compliance with a 35mb inlet pressure is achieved.
