Explosion relief panel

The explosion relief panel is designed to rupture and open at very low over
pressures and must be handled with great care. Never poke/press or lean
against the relief panel and do not bend the frame securing the panel.
Inspect the explosion relief panel with the vacuum unit switched off.
Replace it at the first sign of corrosion or other damage. No other preventive
maintenance is required.
WARNING! Risk of personal injury.
Relief panel must be kept free from debris such as snow, ice, leaves and other
items that might block or prevent explosion panel from opening.
