is preferable to use a hose with a significant amount of water
pressure. DO NOT USE A PRESSURE WASHER
Step 5: Wash all matter from the strainer gaskets and clean
the inner-ring where the bottom of the strainer element rests.
Step 6: Make sure the U-shaped gasket is fitted securely to
the bottom of the strainer element. Reposition the strainer
element into the body of the strainer.
Step 7: Make sure the strainer head gasket is secure on the
top of the strainer body. On V-Band models, O-rings should
be seated completely in the body flange. Reposition the
strainer lid back on the strainer body. Tighten the lid securely
either with the bolts or with the band-clamp.
• For band-clamp models, opening and closing is achieved
without adjusting the lock nut. It is tightened at the
factory to the correct compression. (Minor tightening
may be necessary if the gasket loses memory over time.)
To open the clamp, depress the safety latch and pull the
over-center lever outward. To close the clamp, make sure
the T-Bolt is seated in its receiver and push the over-
center lever back toward the strainer housing. Be sure
that the safety latch is engaged before putting the module
to use.
What Is Water Hammer?
Water hammer is a phenomenon that can occur in fluid
systems with long pipes. Water hammer is a rapid change of
pressure caused by a rapid change in velocity. If the flow has
been abruptly shut off downstream, the pressure in the entire
system is raised very quickly.
What Causes Water Hammer?
Any action that can cause a rapid change in the velocity
of the flow can set off a water hammer, such as closing a
downstream valve, pump stoppage, etc. Typically, for short
lengths of pipe (below 500 feet), downstream valves that
are closed within 1/10th of a second can generate a water
hammer.
What Can Water Hammer Do?
Pressure spikes from water hammer can raise fluid pressures
to dangerously high values. These pressure spikes can cause
serious damage to valves, pipes, strainers, joints, etc. The
ClimaCool Strainer is rated to an absolute maximum pressure
of 150 PSI for bolted lid models, and 125 PSI for band clamp
lid models. A water hammer pressure spike that raises the
pressure higher than the maximum rated pressure may result
in strainer damage, voiding the manufacturer's warranty.
What Can I Do To Prevent Water Hammer?
There are certain precautions that can be taken to prevent or
decrease the effect of water hammer. The addition of a surge
tank or accumulator fitted with a suitable pressure relief valve
and strategically located within the water system may provide
adequate protection against the effects from water hammer.
Careful attention should be given to the design and control
strategy for valves and pumps so their actions do not invite a
water hammer.
Automatic Timer Flush (AFT) Package (Optional)
The ATF-EA-1.5 flush valve package provides an automatic
method for flushing away the debris collected In the strainer's
