Note: Before actioning any installation observe the 'Safety information' in Section 1.
Refering to the Installation and Maintenance Instructions, name-plate and Technical
Information Sheet, check that the product is suitable for the intended installation:
3.1
Check materials, pressure and temperature and their maximum values. If the
maximum operating limit of the product is lower than that of the system in which
it is being fitted, ensure that a safety device is included in the system to prevent
overpressurisation.
3.2
Determine the correct installation situation and the direction of fluid flow.
3.3
Remove protective covers from all connections.
3.4
The AE50S should be installed vertically with the inlet at the bottom. Because of
the way automatic air and gas vents operate they all dribble water and liquid when
discharging air and gas. This is perfectly normal.
We recommend piping the discharge to a safe visible point or drain via an air break.
3.5
For installation on superheated water
applications:
We at Spirax Sarco
recommend 1 to 2 m of
¾
" vertical pipeline should be fitted prior to the inlet of the vent.
On superheated water systems the outlet pipework must be sized to accommodate
any flash steam created during discharge.
Direct the outlet pipework to a safe point of discharge where there is no risk of injury
to persons or damage to property.
3. Installation
Because of the way automatic air vents operate they all
dribble water when discharging air. This is perfectly normal,
because of this we recommend piping the discharge to a
drain via an air break.
