WARNING
Check valves must be in operating position
during operation
For this reason:
– Check valves must be set to operating
position after filling or flushing.
The ball valve in the primary circuit (storage cylinder
supply) is equipped with a check valve. In operating
position, (illustr. 17 on the left), the fluid is only
transported in the direction of flow.
For filling and flushing the installation, the check
valve can be opened by turning the handle to 45°
(Illustr. 17 on the right).
