Fig. 3: Vacuum closure and safety device
WARNING
The vacuum closure and the safety device protect the vacuum space from positive
pressure . Only the manufacturer’s qualified staff may conduct the re-evacuation .
CAUTION
The protective cap (2) retains the valve insert (1) if excessive pressure builds up in
the vacuum space.
• Do not remove the protective cap (2).
• Protect the valve from heat or cooling because embrittlement can lead to the loss
of operating vacuum.
