1/3 or more of the basket open area�
Note: Never disassemble or remove
any strainer component without veri-
fying that the system is depressurized
and drained.
Strainers should be thoroughly flushed
clean after each system operation or
flow test and during routine inspections
as follows:
Step 1. Open flushing connection
valve (Ref� Design Criteria) allowing
flow until drain water runs clear� Close
valve�
Note: If heavy sediment in drain water
persists or there are indications that
all debris such as large stones may
not have been removed, basket must
be removed for cleaning; Proceed to
Step 2.
Step 2. Shut down and drain system�
Step 3. Remove end closure nuts and
bolts, flange and ring gasket�
Step 4. Withdraw basket in slow, hori-
zontal motion to minimize possibility of
debris falling from open inlet end into
body�
Step 5. Empty debris from basket and
clean body interior�
Step 6. Insert basket into body until
open inlet end is fully seated against
inlet connection flange�
Step 7. Install end closure gasket,
flange, and nuts and bolts� Gradually
