4.0 MAINTENANCE
During the working life of the Heat Detector it should require little or no maintenance. However, if abnormal or
unusual environ-mental conditions occur due to plant damage or accident etc., then visual inspection is
recommended. If a fault should occur, then the unit can be repaired by Cooper MEDC.
UNDER NO CIRCUMSTANCES SHOULD ANY ATTEMPT BE MADE TO EITHER UNSCREW THE HEAT DETECTOR
ELEMENT FROM THE ENCLOSURE OR GAIN ACCESS TO THE INSIDE OF THE HEAT DETECTOR ELEMENT.
EITHER OF THESE ACTIONS WILL RESULT IN THE ASSEMBLY BECOMING UNSAFE FOR USE IN A
POTENTIALLY EXPLOSIVE ATMOSPHERE.
If you have acquired a significant quantity of Heat Detectors, then it is recommended that spares are also
made available, (please discuss your requirements with Cooper MEDC's Technical Sales Engineers).
