Disassembly & Reassembly

Disassembling a Strainer

Follow these steps to disassemble a strainer:

1. Carefully clean strainer basket cover plate to remove all

foreign matter, and remove the four bolts and washers from
the end cover plate.

2. Remove the end cover plate (cover plate is on the top of

FS/FSAA/FSA strainers) and o-ring from the strainer
housing.

3. Remove the strainer basket. This may dislodge dirt and

particles into the strainer housing. Check inside the strainer
housing for any foreign material. Be sure to wipe the housing
clean, using a soft cloth.

4. Clean the strainer basket by flushing the basket with a liquid

cleaning agent suited for your application. A soft brush may
be used to dislodge imbedded particles. If the embedded
particles cannot be removed, replace the basket.

NOTE:

 Never tap the basket ends on a hard surface to dislodge particles. This may dent

the basket and make reassembly difficult or cause improper sealing.

5. With a clean, soft cloth, clean the inner face of cover plate, mating face of the strainer

body, and seal ring.

6. Make sure the o-rings are cleaned of all dirt and grime. Check the o-rings for damage. If

the o-rings cannot be cleaned or are damaged or frayed, replace them.

Replace PTFE O-rings

Never reuse PTFE O-rings. Always replace them even if they appear to be in good
condition.
