WARNING

Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use information
can result in death, serious personal injury, property
damage, or damage to the equipment.
Keep this Manual for future reference.
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.
Installation
Before installing the simplex basket strainer, be sure its pressure rating is correct for the system. If the end connections are
threaded, be sure the piping is straight and not at an angle or
offset. If the strainer has flanged ends, be sure the flanges of
the connecting piping are square with the pipe so that no undue
stresses are put on the strainer or piping when tightening flange
bolts. Tighten bolts in sequence crossing to opposites.
Maintenance
For maximum efficiency, a differential pressure gauge 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 cover.
Replace the gasket or O-ring if necessary. Keeping a spare,
clean basket will minimize shut down time.
Spare Parts
To order replacement baskets or gaskets and O-rings, which are
the only items normally required, specify the following.
A. Size and model number of strainer or casting number as it
appears on the body of the strainer.
B. Specify service. For example: water, steam, gas, air, oil. The
working pressure and temperature of the system and particle
size to be strained out should also be specified.
