Removing Temporary Strainer
The temporary strainer must be removed following system
clean up as follows:
After all debris has been removed from the system, or a
maximum of 24 running hours, stop the pump and close the
pump isolation valves. Drain the Suction Guide by removing
the drain plug or opening the blowdown valve, if installed.
Remove the insulation disc held on with Velcro (the disc has a
“CAUTION Remove Startup Strainer After 24 Hours” sticker).
Remove the suction guide cover and remove the strainer
assembly from the valve body.
The temporary ne-mesh start-up strainer is tack-welded to
the permanent stainless steel strainer, see Figure 104. This
temporary strainer should now be removed from the permanent
strainer. The ne-mesh strainer is designed to remove small
particulate from new piping systems and could easily clog with
debris if left in place. This will be detrimental to the operation of
the pump.
Replace the permanent strainer into the tting body once the
temporary strainer is removed.
Inspect the cover O-ring and replace if necessary. Replace
the cover into the body. Ensuring that the strainer is properly
seated, tighten the cover bolts diagonally, evenly and rmly.
The seal may drip at initial start up as it breaks in. If the drip
continues for more than a few hours, service may be required.

Seasonal Shutdown
Follow the instructions in the chiller unit for seasonal shutdown
procedures.
In addition for the pump package:
No components or piping on the pump package are heat
traced. If heat tracing is eld installed, carefully remove
the factory insulation, install the heat tracing and carefully
replace the insulation, being careful to seal it against
moisture penetration.
If draining the chilled water system, see diagrams beginning
on page 15 for the location of drain points in the piping
and pumps, both of which must be thoroughly drained.
