Remove and clean the oval rotors (see chap. "9.4 Dismantle the device"
and chap."9.5 Assemble the device").
Add a strainer of 75 µm upstream of the device.
Clean the strainer.
Replace the rotors (see chap. "10 Spare parts and accessories", "9.4 Dis-
mantle the device" and "9.5 Assemble the device").
Clean the strainer.
Verify specifications, adjust the device or the flow rate (see chap. "6.5
Fluid data [Titel level 2]").
Slowly drain air from the pipe.
Verify the assembly of the rotors in the fitting (see chap. "9.4 Dismantle the
device" and chap. "9.5 Assemble the device").
Make sure that the device has been wired correctly (see chap. "7.3
Wiring").
Dismantle the device and modify the position of the rotors (see chap. "9.4
Dismantle the device" and chap. "9.5 Assemble the device").
Replace the rotors (see chap. "10 Spare parts and accessories", "9.4 Dis-
mantle the device" and "9.5 Assemble the device").
Replace the cover with electronic module (see chap. "10 Spare parts and
accessories", 9.4 and 9.5).
