GAS 222.21 AMEX
DANGER
Toxic, corrosive gas/condensate
Sample gas/condensate may be hazardous to health.
a) If necessary, ensure a safe gas/condensate discharge.
b) Always disconnect the gas supply when performing
maintenance or repairs.
c) Protect yourself from toxic/corrosive gasses/condensate
when performing maintenance. Wear appropriate pro-
tective equipment.
DANGER
Explosion hazard
Life and explosion risk may result from gas leakage due to im-
proper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.
c) Check tubes and hoses for leakage.
DANGER
Danger to life and explosion during installation and
maintenance
The unit must not be worked on (assembly, installation,
maintenance) in explosive atmospheres.
DANGER
Use in explosive areas
Flammable gasses and dust could ignite or explode. Avoid the
following hazard sources:
Application area!
Never operate the gas probe outside the specifications. Ex-
tracting gases or gas mixtures which are also explosive in the
absence of air is prohibited.
Electrostatic charge (sparking)!
The equipment may only be used where normal operating
conditions do not frequently produce flammable, electro-
static discharge.
Always clean plastic housing parts and decals with a damp
cloth.
Sparking!
Protect the equipment from external blows.
Flame propagation!
If the process holds a risk of flame propagation, install a
flame arrestor.
Adiabatic compression (explosion hazard)
Adiabatic compression may cause high gas temperatures
during blowback. Never blowback if gases are explosive. Only
use nitrogen (inert gas) to blowback flammable gas.
Dust:
If possible, take the electrical components which must be
opened for repair to a dust-free room. If unable to do so, pre-
vent dust from entering the housing.
Ignition of dust layers!
When using the device in a dusty environment, routinely
clean dust from all components.
The ignition temperature resp. smouldering temperature of
flammable dusts resp. dust layers present must be consider-
ably higher than the maximum surface temperature of the
probe (observe applicable standards and statutory regula-
tions).
3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. They must be stored in a covered, dry and
dust-free room at a temperature between -20 °C to 50 °C (-4 °F
to 122 °F).
