5.5 Analyzer cell maintenance
Pollution of vacuum circuit components
During maintenance operations for vacuum circuit components, avoid any contamination
which could subsequently result in the degassing of the parts. Special caution must be ex-
ercised to ensure cleanliness. To avoid this:
● Perform the maintenance in an appropriate area (clean, dust-free and ventilated).
● Use non-woven materials.
● Dust the parts with filtered dry air (unless otherwise stated).
● Wear unpowdered vinyl gloves (clean room gloves).
5.5.1 Disassembly/reassembly of the analyzer cell
WARNING
Risk of burns in case of contact with hot surfaces
For the operator’s safety, the products are designed to avoid thermal risk. However, specific operat-
ing conditions may exist that require extra caution on the part of the operator due to the high temper-
atures (surfaces > 70 °C for parts inside the cover(s)).
► Wait for the product to fully cool down before working on it.
► Protective gloves must be worn in accordance with standard EN 420.
Disassembly
1. Create an air inlet on the analyzer cell from the menu
[Maintenance] [Maintenance turbo pump
& cell] [Stop and vent]
(see chapter “Information” in the operating instructions).
2. Power off the leak detector (see chapter “Powering Off”).
3. Remove the cover (see chapter “Cover disassembly/reassembly”).
