Xgard
gas detectors must be installed, operated and maintained in
strict accordance with these instructions, warnings, label information,
and within the limitations stated.
•
The lid on flameproof versions of
Xgard
must be kept tightly closed
until power to the detector is isolated otherwise ignition of a
flammable atmosphere can occur. Before removing the cover for
maintenance or calibration purposes, ensure the surrounding
atmosphere is free of flammable gases or vapours.
•
Xgard
detectors are designed to detect gases or vapours in air, and
not inert or oxygen deficient atmospheres.
Xgard
oxygen detectors
can measure in oxygen deficient atmospheres.
•
Electrochemical cells used in toxic and oxygen versions of
Xgard
contain small volumes of corrosive electrolyte. Care should be
observed when replacing cells to ensure that the electrolyte does not
come into contact with skin or eyes.
•
Maintenance and calibration operations must only be performed by
qualified service personnel.
•
Only genuine Crowcon replacement parts must be used, substitute
components may invalidate the certification and warranty of the
detector.
•
Xgard
detectors must be protected from extreme vibration, and direct
sunlight in hot environments as this may cause the temperature of the
detector to rise above its specified limits and cause premature failure.
A sunshade is available for Xgard.
•
This equipment must not be used in a Carbon Disulphide atmosphere.
•
Xgard
Types 2, 3, 5 & 6 are certified for use in atmospheres that may
contain flammable dusts. They will not however detect the presence
of flammable dust, and the response of the gas sensor may be
compromised by becoming blocked in a dusty environment.
Xgard
detectors should be inspected regularly if used in a dusty
environment.
