7. Care & Maintenance
7.1 Safety warning
As this equipment has been designed as non-electrical equipment for potentially explosive
atmospheres. Specific precautions have to be taken regarding maintenance of the device. The
user can exchange parts and modules if following points are observed:
1. Never carry out any repair or trouble shooting in a hazardous area.
2. Substitution of components may impact safety. Use only original spare parts.
3. Work shall be done only by maintenance personnel who has experience with equipment
certified for use in potentially explosive atmosphere.
The design of the equipment is modular, i.e. in case of damage, check which modules or spare
parts have to be replaced. Order new parts according to enclosed drawings and specific item
number TS -----. The instrument consists of the following modules:
Mechanical parts
Tape assembly
Tape cleaner
7.2 Care
Clean the instrument of any excess of liquid after use. Remove the winder holder and clean the
storage tube. This cleaning must be done very properly, in particular when corrosive liquids are
sampled, such as strong acids or caustic soda for instance.
Store the instrument in a dry location.
Check periodically whether the general state of the device is still OK.
Check periodically whether all sealings are still OK.
Check the tape wiper for wear.
Clean periodically the sampling bottle. Check the valves of sampling bottles for liquid leakage.
Check periodically tape for kinks.
Check periodically (at least every 6 months) the continuity of grounding by measuring the electrical
resistance between the hook lock (or the sampling bottle) and the quick connect coupler.
Resistance should not exceed 100
.
7.3 Sampler cleaning
To clean HERMetic Sampler A2, winder holder can be easily removed and sampling bottle
detached from tape.
It is required to fit the cleanliness level with the sample goals. Where appropriate, dismantle the
winder holder and clean the parts with an appropriate cleaner to prevent any contamination of the
sample by the sampler itself.
