STRAINER INSTALLATION INSTRUCTIONS
A . Ensure all machined surfaces are free of defects and that the inside of the
strainer is free of foreign objects.
B . For horizontal pipelines, the strainer should be installed so that the drain
connection is pointed downwards.
C . For flanged end strainers, the flange bolting should be tightened gradually in
a back and forth clockwise motion.
D . Once installed, increase line pressure gradually and check for leakage around joints
E . If the strainer is supplied with a start-up screen, monitor pressure drop carefully.
