Installation / Commissioning instructions
Prior to commissioning, check that :
- the device is suitable for the installation category
- the conditions of operation are compatible with the fluid category
- the check valve is working properly, by testing it a couple of times
On a new installation or after maintenance, the circuit should be rinsed in
order to flush out any solid bodies which might damage the internal parts of
the valve.
The circuit should be gradually brought up to pressure to avoid damaging the
internal parts of the valve. Check that when the flow stops, the check valve
does indeed maintain the pressure. After a prolonged stoppage, a change in the
fluid state can cause damage when the installation is restarted
(solidification, etc.).
An opening/closing manipulation must be done every three months to avoid valve
scaling.
