Reinstall the screen in the strainer in the same position
as before and tighten the cover or cap. Replace the

Keeping a spare, clean screen will minimize shut

installed across the inlet and outlet will indicate pressure
loss due to clogging and may be used, as a guide, to
determine when cleaning is required. If the strainer is not
set up for backwash cleaning, remove the cover access to
the basket. After cleaning, replace the basket in the same
position as before and tighten the cover. Replace the
gasket or O-ring if necessary. Keeping a spare, clean
basket will minimize shut down time.
Warning: Individuals performing removal and disassembly
should be provided with suitable protection from possibly
hazardous liquids. Knob and clamp type quick opening
covers should not be used for high temperature service.
Consult factory for recommendations. ‘–‡ǣ‹‹—͚͔
