Checking the high pressure adaptor
A 400 µm strainer is built into the high pressure adaptor to protect the flow control valve. We
recommend cleaning this strainer twice a year.
We recommend shortening the maintenance interval according to the degree of
contamination of the tested fluid.
The flow through the high pressure adaptor is regulated to
≈
0.55 ...0.7 l/min. Maintenance
should be performed if this flow is not reached.
11.4.1 Cleaning / changing the strainer in the high pressure adaptor

D
A
Remove the measurement coupling (A) from the union (D) with an open-jaw wrench (size 22
mm) in a counterclockwise direction. Then unscrew the strainer (B) with a Philips head
screwdriver or the special tool (see accessories list 13.1) in a counterclockwise direction.
The strainer (B) can be washed out and blown dry with compressed air.
TIP
Operating the FCU without a suction strainer can lead to malfunction.
To mount the strainer (B), screw it in to the union (D) in a clockwise direction using a Philips
head screwdriver or the special tool.
Then check the sealing ring at the measurement coupling (A) for damage and replace if
necessary. Turn the measurement coupling (A) completely in a clockwise direction and
screw tight with 25 Nm.
