SERVICE, MAINTENANCE & DISPOSAL
NOTE
If a detector is damaged, a replacement may be obtained from the
manufacturer. See the Conditions of Safe Use for details. Otherwise, there are
no user serviceable parts. For repairs or decommissioning, return to the
manufacturer.
6.1 Equipment Service
A number of external system based checks
should be completed on a regular basis. These ‘routine
inspec
tions’ must be carried out by suitably trained people with knowledge of the GG2 Detector and the
systems into which it is fitted. Routine inspections may take the form of either visual-only checks, or
visual and ‘hands-on’ checks.
6.1.1 Visual Only Inspections
A basic visual inspection focuses on looking at the installation for signs of physical damage, water or
dust ingress, and the condition of cables and labels. This type of inspection may involve opening
cabinets to gain access to the unit and other equipment. This level of inspection may also include
cleaning display windows that have become obscured by dirt.
Observations would typically be:
Check that equipment enclosures, cable trays, conduits, etc. are in good order with no physical
damage.
Check that sealed wall boxes are free from water and dust ingress internally. Door seals are in
good condition.
Check that connected cables are free from cuts, abrasions and obvious signs of damage. Cable
restraints are in good order and correctly fitted.
Check that labels on equipment, wall boxes and cables are present and in good condition
(especially certification labels).
Check that no modifications have been carried out to installed equipment.
6.1.2 Hands-On (Detailed) Inspections
A more detailed inspection would include all of the elements of a visual inspection, plus some checks
that cover the integrity of connections, fixtures and fittings.
In addition to basic visual observations, more detailed integrity checks would involve:
Verify that equipment housings, wall boxes and other mechanical fixtures are secured in place.
This includes terminal box lids, tightness of cable glands, integrity of wall-box mountings, security
of equipment fixing to walls/DIN rails etc.
Verify all electrical connections are secure with no loose screw terminals or DIN rail terminals not
fitted to rails etc.
6.2 Equipment Maintenance
Refer to GG2B023 GG2 Display User Manual for an overview of calibration and testing procedures.
6.2.1 Periodic Maintenance
Periodic maintenance consists mainly of scheduled checks to ensure the instrument remains in
adjustment and gives the required response to sampled gas. For recommended maintenance tasks
and schedules, refer to the AS/NZS 2290 series.
