Only run the pump when the system is filled, dry running will destroy the pump. The
recommended flow rate for systems up to 12 m² is 1 l per minute per square meter (m²)
absorber surface (10 tubes = 1 m²).
1. Set the pump to low speed and switch it on manually using the controller
(see the following paragraph).
2. If the flow is higher than required set the flow meter to the required flow rate by
adjusting the shut-off valve using a screw driver (as shown in the drawing) whilst
the pump is running. Repeat this step until the value reaches the required flow rate.
3. Stop the pump.
