Warning
To avoid possible personal injury:
• Substitution of components may impair
intrinsic safety.
• Do not use the detector if it is damaged or
something is missing, contact Crowcon
immediately.
• Use only sensor modules specifically
designed for your Gasman. (Please see the
section on replacement parts and accessories.)
• Periodically, “bump test” the sensor with
gas to confirm its ability to respond to gas
by exposing the detector to a targetted gas
concentration that exceeds the high alarm
setpoint. Manually verify that the audible
and visual alarms are activated.
It is recommended that the detector be calibrated before first-time use, and then at
least once every 90 days and only by qualified personnel.
For use in potentially explosive atmospheres
where oxygen concentrations do not
exceed 21%(v/v).
Do not turn off the detector during a work
shift. Turning off the detector resets the
time weighted average gas exposure values
to zero.
Ensure that the sensor is not blocked.
High off-scale %LEL readings may indicate
an explosive concentration.
Only charge the battery using a Crowcon
supplied charger.
Do not use any other charger. Other chargers may damage the detector making it
unsafe for use in hazardous areas.
Do not change or charge batteries in a hazardous location. Doing so may lead to fire
or explosion.
Flammable Gas Units Only
• Extended exposure of the flammable sensor
to certain concentrations of combustible
gases and air may stress the sensor element, which can seriously affect its performance. If an alarm occurs due to a high
concentration of combustible gases, recalibration should be performed, or if needed,
the sensor replaced.
• Do not test the combustible sensor’s
response using a butane lighter. Doing so
may damage the sensor.
• Prior to each days usage, sensitivity must be
tested on a known concentration of
methane equivalent to 25-50% of full scale
concentration (accuracy must be within
0±20% of actual). Accuracy may be corrected by recalibrating the instrument.
• Any rapid up-scale reading followed by a
declining or erratic reading may indicate a
gas concentration beyond the upper scale
limit, which may be hazardous.
