simultaneously for 15 seconds (two flashing light fields indicate that the

pump is in configuration mode).

3. Keep the buttons depressed, and the flashing light fields will change.

See the meaning of the different settings in the table below.

9. Start-up

Do not start the pump until the system has been filled with liquid and vented.

Furthermore, the required minimum inlet pressure must be available at the

pump inlet. See the general installation and operating instructions.

9.1 Venting the pump

Vent the pump before start-up. See figure below.

Due to air remaining in the pump, the pump may be noisy when first switched

on. This noise should cease after a few minutes of operation.

After start-up, set the desired operating mode and head.

Note

The system cannot be vented through the pump.

Warning

When the air vent screw is loosened, scalding hot liquid

under high pressure may escape. Take care that escaping

liquid does not cause personal injury or damage to

components.
