and 2 for flammable versions and Zones 0,
1, and 2 for toxic and oxygen versions, for
Group IIA, IIB, and IIC gases and vapours
for Temperature Classes T1, T2, T3 and T4
2. 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.
3. Compliance with the 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.

From the 1st November 2010, EN60079-
29 part 1 has been harmonised under
the ATEX directive 94/9/EC. Therefore to
comply with the ATEX directive, portable
apparatus sensing flammable gases should
have a functional check with gas before
each day of use. Other testing regimes
may be employed depending on local
circumstances.
Area Classifications: -
Zone 0: An area classified as Zone 0 is an
area in which an explosive mixture
of gas is continuously present or
present for long periods.
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 concentra-
tions of flammable gases, vapours
or liquids present under normal
operating conditions.

Gasman
Personal Single Gas Monitor
Thank you for purchasing the new Gasman Personal Gas Monitor.
Gasman has redefined portable gas monitoring and will give you years
of unparalleled service and reliability.
Please read the instructions carefully before use. Keep the manual for
future reference.
Unpacking
Remove the Gasman Personal Gas Monitor from the packaging. The
Gasman accessories will be located in the bottom of the box. Check the
contents are complete, you should have:
• Gasman unit with alligator pocket clip;
• A configuration report detailing the sensor installed, alarm
settings and a calibration certificate;
• Calibration flow cap and tubing;
• Usermanual.
Optional battery chargers and other accessories will be packed in a
separate box.
Battery check
The Gasman Personal Gas Monitor has two battery options: Li-ion
rechargeable or non-rechargeable batteries. The label on the back of the
detector will have either NR (non-rechargeable) or R (rechargeable) to
indicate which battery option is within the detector.
Rechargeable units
Gasman uses a Li-ion battery pack and should arrive with sufficient
charge so that the unit can be used straight out the box. However, if
this is the first time you have used the Gasman unit, you may need
to charge the battery to attain the full operating time. (The actual
operating time will depend on the types of sensor installed.) The
flammable Gasman will operate for at least 12 hours on a fully charged
battery.

Warning: rechargeable units
Only charge the rechargeable Gasman Personal Monitor with a Crowcon
Gasman charger. Failure to comply could invalidate safety certification,
warranty and safety; and may result in permanent damage to the unit.
Non-rechargeable units.
Gasman uses a CR2 battery which can be easily field replaced. Ensure
only the correct types of battery are fitted to maintain compliance with
certification (see Battery check on page 1).
Gasman IR CO2Personal Single Gas Monitor
The Gasman IR CO2personal single gas monitor an infrared gas sensor
for CO2detection. This version of Gasman is not designed or certified
for use in a hazardous area, and the safety certification data in Section
X is not applicable. Operation and maintenance of the Gasman IR CO2
is essentially the same as for other Gasman units but with the following
points to note.
CO2is present in ambient air at a background concentration of just under 400ppm (0.04%). In
any enclosed environment the ambient CO2concentration will increase as a result of respiration
and if the room is poorly ventilated concentrations well in excess of 1000ppm (0.1%) can
occur. CO2levels in the outdoor air will also be enhanced by any emitted CO2e.g. from vehicle
exhausts or boiler flues venting to atmosphere so it is normal to see fluctuating levels of CO2on
the display whether indoors or outside.

Gasman warm up sequence
a) The Gasman will demonstrate
the alarm LEDs, sounder,
vibration alerts, and the
operator display screen. The
sounder may be silenced by
pressing the button.
The Gasman screen will show the following display during the
warm up sequence. This will take approximately 20 seconds.
Note: these screens may differ depending on what sensor is being used.
b) Autozero
If Autozero is enabled (default), the unit will display the Autozero
confirm screen: the display will alternate between ‘ZERO’ and
‘????’. Press the operator button with a single click to confirm
Zero. If the operator button is not pressed within the 10 second
time out, Gasman will proceed directly to Run mode without
performing Zero.
