PERIODICAL CHECKS & OPERATING ANOMALIES
7.1
PERIODICAL CHECKS
•
To check the sensitivity of the detector, it is essential to have a Refrigerant gas « Test
Leak » of known value.
Present the pipe to port sniffing
« Test leak »
.
Check the correct lighting of the lightbar and the response time.
If the Sensitivity of the Detector has been checked with an R134a Test Leak on the position
« HFC »
or 1234ze on the position
« HF0 »
sensitivity can be considered as valid for other
gases or mixtures.
•
As part of the Quality Assurance standards, we recommend that you carry out an annual
audit at the Vulkan manufacturer, which will draw up a verification report in accordance
with the EN 14624 standard valid for one year.
NEVER EXPOSE THE DETECTOR TO A JET (EVEN VERY FINE) OF PURE GAS TO
TEST THE SENSITIVITY. THIS WOULD DESENSITIZE OR DESTROY THE
DETECTION CELL.
