FlowBox Solar 7000
Flow volume adjustment (Fig. 2)
- The flow volume is set on the regulating valve using an SW 4 Allen
Key.
- The set volume can be directly read on the scale.
- The valve stroke is spread over several spindle revolutions, thereby
permitting a high level of setting precision.
- The setting values are based on the calculations for the system.

Gravity brake (Fig. 3)
- For filling, flushing and draining the system, the gravity brake must be
open. It is opened by turning the ball valve to the 45° position.
For normal operation of the system, the ball valve must be completely
open.
