: CASAGRANDE STYLE FILTER ASSEMBLY
Saturation Instructions:
1 Remove the sealing screw from the bottom end of the piezometer.
2 Fill a bucket full of water.
3 Immerse the piezometer in the bucket of water so the sealing screw is pointing
upwards.
4 Allow the air within the piezometer to escape. Gently tap and move the
piezometer around underwater.
5 Replace the sealing screw underwater after all the air has been removed from
the piezometer.
6 Note that with a low-pressure range piezometer (70 kPa), readings must be
taken with a readout box while carefully pushing the filter housing on so as not to
over-range the sensor.
7 To maintain saturation, the unit should be stored under water until installation.
