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 overcenter 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 ft), 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 .
