MAINTENANCE

It is essential that operation and maintenance in explosion hazard areas are only carried out by 

trained specialist personnel authorised to do so by the system operator.

For maintenance and repair work in explosion hazard areas, the standards EN60079-17 or 

IEC60079-17, EN60079-19 or IEC60079-19 and the relevant national regulations must be 

applied.

In the U.S. maintenance and inspection must be carried out in accordance with ANSI / ISA 

RP12.6.01-2003 and the NEC.

In Canada maintenance and inspection must be carried out in accordance with CEC

6.1  Filter replacement

The protective filter should be cleaned or replaced periodically, in particular whenever

it has been noted that the response time has become longer.

When replacing a filter, ensure that the sensor is NOT touching the metallic filter cap!

6.2 Cleaning

6.2.1  Cleaning the display

To clean the display screen, use a damp cloth to avoid static. 

6.2.2  Cleaning the sensor

Thanks to the very robust design of the sensor element, any cleaning required is very easy to 

carry out. This can be carried out using suitable chemicals such as isopropyl alcohol (normal 

industrial product). After cleaning in isopropyl alcohol, dip the sensor element in water and 

allow to dry. The cleaning time should not be more than 2 mins. To avoid damaging the sensor 

layer, the use of mechanical equipment is not permitted!

When screwing on the filter cap, ensure that the sensor is NOT touching the metallic filter cap!

6.3  Customer adjustment of humidity and temperature
