3. The equipment is certified for use in ambient
temperatures in the range –20°C to +65°C
(-4 to +149 F). The equipment should not
be used outside these ranges. Toxic and
Oxygen sensors are not rated for continuous
operation at high temperatures greater than
40°C (104°F).
4. Compliance with Essential Health and
Safety Requirements has been assured by
compliance with EN60079-0:2004 + Amds 1
& 2, EN60079-1:2004 and EN60079-11:2006,
as certified by Baseefa. Compliance with gas
detection performance standards EN50054,
EN50057, EN61779-1 and EN50104 has been
certified by Lloyd's Register. EMC compliance
to EN50270 has been certified by 3C Test Ltd.
5. Repair of this equipment and gas sensor
replacement shall be carried out by the
manufacturer or approved service centre in
accordance with the applicable code
of practice.
6. If the equipment is likely to come into contact
with aggressive substances, then it is the
responsibility of the user to take suitable
precautions that prevent it from being
adversely affected, thus ensuring that the
type of protection is not compromised.
7. The rechargeable battery must only be
charged in non-hazardous (safe) areas by
connection to the specified Linde charger.
Rechargeable batteries can only be replaced
by a Linde Group Authorised Service Centre.
8. Only the following CR2477 battery types are
approved for use in the battery compartment
of the non rechargeable product variants:
Panasonic, GP, Energiser and Maxell. Do
not use Duracell batteries. Batteries must
only be changed in a non-hazardous
(safe) area. Users can only change non
rechargeable batteries in G-TECTA
SG instruments.
9. The equipment is not certified for use
in atmospheres containing more than
21% Oxygen.
Area Classifications
Zone 0: An area classified as Zone 0 will always
have ignitable concentrations of flammable
gases, vapours or liquids present under normal
operating conditions.
Zone 1: An area classified as Zone 1 is likely to
have ignitable concentrations of flammable
gases, vapours or liquids present under normal
operating conditions.
Zone 2: An area classified as Zone 2 is not likely
to have ignitable concentrations of flammable
gases, vapours or liquids present under normal
operating conditions.
Instructions – specific for use
in non-hazardous areas
G-TECTA
The G-TECTA
infrared gas sensor for CO
of G-TECTA
use in hazardous areas, and the intrinsic safety
information for this instrument is not applicable.
Operation and maintenance of the G-TECTA
is essentially the same as for other G-TECTA
instruments but with the following points to note.
CO is present in ambient air at a background
2
concentration of just under 400ppm (0.04%).
In any enclosed environment the ambient
CO concentration will increase as a result of
2
people or animals breathing and if the room is
poorly ventilated concentrations well in excess
of 1 000ppm (0.1%) can occur. CO
the outdoor air will also be enhanced by any
emitted CO
flues venting to atmosphere so it is normal to
see fluctuating levels of CO
display whether indoors or outside.
