5.0 MAINTENANCE
During the working life of the unit, it should require little or no maintenance. GRP will resist attack by most
acids, alkalis and chemicals and is as resistant to concentrated acids and alkalis as most metal products.
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.
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.
