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 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.
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.
During maintenance, if the cover/lens assembly grease
needs to be re-applied, a PFPE (Perfluoropolyether) based
grease such as Krytox GPL203 by DuPont or Perfluorolube
22/6 by Performance Fluids Ltd should be used, to
prevent damage to the O-ring.
