Maintenance
Ionisers require periodic cleaning. During normal operation, dirt will build-up on
the emitter pins and upon the body of the ioniser. This will cause a reduction in
performance.
Typically, weekly cleaning is sufficient. However, equipment used in some heavy
contamination areas, such as gravure printing or where plastic fumes are present, may
require daily cleaning. Equally, in a Class 100 area, cleaning may only be required
on a monthly basis. Advanced systems with performance monitoring, e.g 977CM and
904CM, will alert the operator to the need to clean the equipment before performance
drops to an unacceptable level.
Before cleaning, ensure that the equipment is switched off. Emitter pins can be
cleaned very effectively with a brush. A dry toothbrush is ideal.
Ionising bars will need periodic wiping to clean grey deposits from the surface
of the bar. A cloth moistened with a small amount of IPA or methylated spirits is
recommended. Allow a moment to dry before switching back on.
The Bar Should not be washed down.
