Note: Before actioning any maintenance programme observe the 'Safety information'
in Section 1.
The AE50S is a sealed automatic air and gas vent. It is adjustable and requires no
maintenance.
After installation or maintenance ensure that the system is fully functioning. Carry out tests
on any alarms or protective devices.
At start-up the air vent is open allowing air to pass through the main valve. As soon as water
reaches the vent the float is raised and the lever mechanism closes the valve.
When more air reaches the vent it displaces water and the float falls thus opening the valve.
After the air is discharged the valve is closed, as the water level rises to replace the air.
