•
Check the unit’s production date and service life span
This list may not be exhaustive
Note that the entire system, including all parts/components, must be checked regularly in accordance with the
supplier’s guidelines and/or local laws. International guidelines recommend performing monthly checks on the
following components, electric wiring, electric contacts, fixed bolts and generators casing.
Please be aware that the extinguishant contains materials that have a relatively low melting temperature. These
materials increase the extinguishant’s efficiency, but it is therefore important to always ensure that the AF-X
Fireblocker is not exposed to temperatures that are outside the normal operating temperature range of -10 and +
50 degrees Celsius, as stipulated in this manual. The service life of the AF-X Fireblocker is monitored by the
producer by testing product batches on a regular basis.
7.1
Maintenance task for the user of the AF-X Fireblocker system
The installer shall provide the user with an inspection programme for the system and components. The
programme should include instructions on the action to be taken in respect of faults.
The user’s inspection programme is intended to detect faults at an early stage to allow rectification before the
system may have to operate. A suitable programme is as follows.
a) Weekly: Visually check the hazard and the integrity of the enclosure for changes which might reduce the
efficiency of the system. Carry out a visual check that there is no obvious damage to cables and that all operating
controls and components are properly set and undamaged.
b) Monthly: Check that all personnel who may have to operate the equipment or system are properly trained and
authorised to do so and, in particular, that new employees have been instructed in its use.
WARNING — Always operate a system isolate switch prior to entering the protected enclosure if the unit is not
designed for occupied spaces.
