5– CLEANING PRECAUTIONS
5.1 Basic precautions
DGPT2
®
plastic body is made of a transparent polyamide specifically treated against
ultraviolet with an improved outdoor weathering behaviour.
When the DGPT2
®
plastic body needs to be cleaned, always make sure that the
composition of the cleaning product (or leak detection product) does not contain
any chemical listed on page 9. Diesel fuel and kerosene are excellent cleaning
agents.
If you use a cleaning product containing one of these chemicals, cracks caused by
the stress release inside the polyamide will appear on the DGPT2
®
plastic body.
These stress-cracks will cause leaks and make the DGPT2
®
inoperative until its
plastic body has been replaced.
5.2 Loss of transparency
In contaminated atmosphere, successive layers of deposit can alter the DGPT2
®
plastic body transparency, and even totally occult the visibility of both the dielectric
level and the floats.
In that case, the best way to recover partial visibility is:
To use a cleaning product containing no chemical listed on page 9.
To use an ultrafine plastic or painting polishing compound used for car body.
