4. MAINTENANCE
During the working life of the unit, it should require little or no maintenance. However, if abnormal or unusual
environmental conditions occur due to plant damage or accident etc., then visual inspection is recommended.
The replacement of the xenon tube, See below, can be carried out by competent site personnel. Other repairs
should be undertaken by returning the unit to MEDC or by an authorised repairer of Ex equipment.
If you acquired a significant quantity of units, then it is recommended that spares are also made available. Please
discuss your requirements with the Technical Sales Engineers at MEDC
