Storage
Installation
For prolonged storage, factors such as temperature, humidity,
saline atmosphere, etc. may damage the detector elements.
In this case, it may have operating problems.
Before starting up after storage for over six months, it is
recommended to change all the seals (contact customer
service).
The seal kits must be kept away from heat and light (direct
sunlight and ultraviolet light) in order to prevent hardening of
the elastomers.
The performances of the detector (pumping speed, accuracy
and reliability) depend on:
- the ambient temperature;
- the vacuum connections;
- the frequency and quality of maintenance;
- the helium calibration.
Position the unit so there is no possible risk of the unit falling
or tilting.
