11. Storage
Before the system is stored, all traces of any medium residue
must be removed. This is particularly important if the medium
is a health hazard such as corrosive, toxic, carcinogenic,
radioactive, etc.
Before installation, in order to prevent damage to the pressure instru-
ments, the following points should be observed:
The pressure transmitter should be left in its original packing until installation.
After taking the transmitter out (e.g. for tests), reuse the original packaging
material.
The storage temperature should not be less than -40 °C or more than +70 °C.
Avoid the following influences:
Direct sunlight or vicinity to hot objects
Mechanical vibration
Soot, steam, dust, humidity and corrosive gasses
Potentially explosive environment, inflammable atmosphere
12. Maintenance and servicing/cleaning
The instruments require no maintenance or servicing and will give very long
service when handled and operated properly.
The indicator and switching function should be checked once or twice every 1
months. The instrument must be disconnected from the process before being
checked using pressure testing equipment.
The instruments should be cleaned with a damp cloth, moistened with soap
solution. Clean the instrument with a damp cloth. Particularly with regards to
ATEX model do not use a dry cloth for cleaning (electrostatic charging!)
Ensure that all parts are dry before the power is switched on again.
