4.0 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.
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.
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.
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.
Removing/replacing xenon tube
CAUTION: Before removing the cover assembly,
ensure that the power to the unit is isolated.

These units each contain two separate xenon tubes
which should both be replaced at the same time.
Unscrew the setscrew on the cover one full turn
(2.0mm A/F hexagon key). Carefully unscrew and
remove the cover assembly (using a 120mm hook
wrench if required).
Remove the old tubes by unscrewing the terminal block
fixings. The replacement xenon tubes can now be fitted
(see the xenon tube installation sheet, which is supplied
with the replacement tube).
To replace the cover, use the same procedure as above
but in reverse manner, ensuring the cover is screwed
down tightly and ensuring there is no damage to
the thread surfaces or mating faces of the cover and
enclosure. There should be a maximum gap of 0.2mm
between the faces of the cover and enclosure to ensure
correct o-ring compression and maintain the IP rating of
the unit.
