4.0 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.
If the unit requires cleaning, then only clean exterior with
a damp cloth to avoid electro-static charge build up.
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 a unit fault should occur, then the unit can be repaired
by MEDC. All parts of the unit are replaceable.
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.
