or halogenated hydrocarbons,
ketones, esters, alcohol’s (over
25%) and acids (over 25%),
they will cause “crazing”
especially of the UV transparent
plastic and should not be
used for cleaning. Do not use
abrasive creams or scourers. Dry
components with clean tissues
prior to use.

Maintenance
• To remove the safety lid, push thumbs down on
the plastic lugs and lift the lid vertically with
your fingers.

leakage will be seen on the tissue paper. If any
leakage is seen, do not attempt to repair or use
the apparatus, but notify Hoefer technical support

able water-soluble disinfectant, to reduce the risk
of infection.
