WARNING
NEVER
attempt to assemble,
dis as sem ble or adjust the
fi
lter when
there is pressurized air in the system.
Starting the pump while there is any
pressurized air in the system can
cause product failure or also cause
the
fi
lter lid to be blown off, which can
cause death, serious personal injury
or property dam age.
8.
While the DE
fi
lter grid assembly is out of the
fi
lter tank, rinse the inside of the tank with water.
Replace drain plug.
9.
Gently rinse the grids with water. After cleaning
the
fi
lter grids, place the grid assembly back into
the
fi
lter tank bottom (see Sections 6.4 and 6.5 for
further grid cleaning instructions).
10. Replace the tank o-ring and tank lid.
11. Reinstall the tank clamp ring. See Section 3.5 for
tank clamp ring installation.
12. If applicable, open the valves closed in step 4.
5.2 Filter Grid Disassembly/Assembly
1.
Remove the complete grid assembly by following
the instructions in Section 5.1, steps 2-6.
2.
Remove the manifold by
fi
rst unscrewing the tie
rod knob in the center of the manifold. Then lift
the manifold assembly off of the grids and the
outlet tube.
3.
Remove the top spacer from the grids.
4. The
individual
fi
lter grids can now be removed
from the grid support. Use care to avoid damaging
the grids.
5.
See Figure 8 for the arrangement of
fi
lter grids in
the
fi
lter grid assembly.
6.
To reassemble the
fi
lter grid assembly, arrange
the
fi
lter grids into position on the bottom plate
(see Fig. 9). Use the plastic top spacer to hold
the grids in place.

Section 5. Filter Disassembly and
Assembly
5.1 Filter Tank Disassemby/Assembly
1. Backwash
fi
lter according to the instructions in
Section 6.2.
NOTE Omit this step when
fi
rst starting a new
fi
lter.
2.
Turn off the pump. Switch off the circuit breaker
to the pump motor.
3.
IMPORTANT: Completely open air release valve
on top of the
fi
lter tank to release all pressure
from inside the tank and system.
4.
If the equipment is installed below water level,
close the
fi
lter isolation valves on the system to
prevent
fl
ooding.
5. Close
the
fi
lter isolation valves on the system to
prevent
fl
ooding. Remove the drain plug located at
the bottom of the
fi
lter tank and allow the tank to
drain.
6.
Remove the tank clamp ring from the
fi
lter and
remove the tank lid. Inspect the tank o-ring for
cracks or tears and replace if necessary
7.
Pull the DE
fi
lter grid assembly out of the
fi
lter
tank bottom. Use the handles molded into the
manifold to aid lifting.
