ClimaCool Y Type & Basket Type Strainers
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. 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.
Threaded end strainers should use an appropriate sealant.
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.
IMPORTANT! Ultimate responsibility for strainer and
material selection rests with the end-user or facility
manager, as only the end-user or facility manager knows
the particular application and operating parameters to
which the strainer will be subjected.
CAUTION: PRIOR TO DISMANTLING THE
STRAINER FOR CLEANING, IT IS IMPERATIVE
THAT THE STRAINER ASSEMBLY IS ISOLATED AND
COMPLETELY DE-PRESSURIZED.
Strainer Removal Instructions
A. Drain piping.
B. Vent line to relieve pressure.
C. Loosen flange bolts (flanged ends).
D. Secure necessary lifting equipment to strainer assembly.
E. Remove inlet/outlet flange bolts (flanged end), or
unthread (threaded ends) and carefully remove strainer.
F. Tighten cover. The strainer is ready for line start-up.
For Basket Strainers, Follow Steps G through L.
G. Drain piping.
H. Vent line to relieve pressure.
1. Loosen cover and open to access basket.
J. Remove, clean and replace basket in original position.
(Note: In some instances, a high pressure water jet or
steam may be required for effective cleaning).
K. Inspect cover gasket for damage. If necessary, replace.
(Note: If spiral wound gaskets have been used, they must
be replaced and can be used again).
L. Tighten cover. The strainer is ready for line start-up.
Y Type & Basket Type Strainers
CAUTION SHOULD BE TAKEN DUE TO POSSIBLE
EMISSION OF PROCESS MATERIAL FROM PIPING.
ALWAYS ENSURE NO LINE PRESSURE EXISTS
WHEN OPENING COVER.
Maintenance Instructions
For maximum efficiency, determine the length of time
it takes for the pressure drop to double that in the clean
condition. Once the pressure drop reaches an unacceptable
value, shut down line and follow the "Strainer Removal
Instructions" above.
A pressure gauge installed before and after the strainer
in-line will indicate pressure loss due to clogging and may
be used to determine when cleaning is required.
Trouble Shooting Guides and Diagnostic Techniques
A. After pressurizing, inspect cover and other joints for
leakage. Gasket replacement or cover tightening is
necessary if leakage occurs.
B. If the required filtration is not taking place, ensure the
screen is installed in the correct position, and that the
screen is mounted flush to the upper and lower seating
surfaces.
