1. Only the combustible gas detection portion of this instrument has been assessed for
performance by CSA.
2. Refer to local or national regulations relative to installation and use at the site.
Note: This equipment is designed and constructed to prevent ignition sources arising,
even in the event of frequent disturbances or equipment operating faults. The
electrical input is protected with a fuse.
3. Installation should consider not only optimum siting for gas detection related to potential
leak points, gas characteristics and ventilation but also placement where the potential for
mechanical damage is minimised or avoided.
4. Observe precautions for handling electrostatic discharge sensitive devices when accessing
the interior of the Transmitter Unit.
5. Calibration procedures should only be performed by qualified personnel.
6. Ensure that when forcing signals on the Transmitter Unit's output that the effects on the
network and controller are understood.
7. Ensure that the Apex Transmitter Unit or Junction Box flamepath is not damaged during
dismantling procedures. The flamepath is formed by the mating surfaces of the unit's top
and base.
8. During installation/maintenance only use the supplied parts. Replacement with alternatives
will invalidate certification.
9. Exposure to fluorinated hydrocarbons or silicones will poison the sensor beads on catalytic
sensor cartridges. If a sensor is known to have been poisoned then it must be re-calibrated.
If not sure then flow gas over the sensor and if the reading is incorrect re-calibrate within the
cartridge's tolerance value.
10. Only cartridges with the following part numbers can be fitted to the Certified Sensor:
2110B30x0, 31x0, 32x0, 33x0, 34x0, 35x0 series
2110B3700 - 2110B3999 range
Note: Certified to CSA C22.2 No. 152 only when fitted with specific cartridges.
See specifications for details.
11. Do not use the unit where the temperature is lower than -40°C (-40°F) or higher than
+65°C (149°F).
12. Exposures to gas above the recommended range may result in ambiguous readings and
may require subsequent re-calibration of the sensor.
13. Review cartridge data sheets for operating temperatures and humidities, which are
determined on a cartridge by cartridge basis.
14. Dispose of in accordance with local disposal regulations. Materials used:
