Figure 4-2 H-310 Nose piece/Stainless steel screen
Step 4- Rinse the pressure ports with water to clear mud and silt. You may want to swish the
H-310 in a bucket of water or in the stream it is monitoring to rinse out the pressure
ports.
CAUTION: Be careful not to create large pressures by using sticks and the like to push
debris out of the way. This may cause a plunger effect, and thus over
pressure the H-310. USE COMMON SENSE.
Step 5- Replace the plastic filter and the stainless steel screen. Position the joints of the two
screens 180 apart. The end of the stainless steel screen with a slight bend should be on
the outside. Compress the screen with a turning action and slip both screens into the
groove in the nose piece.
Step 6- Slide the plastic slip ring into place such that the screen fits inside the groove of the
ring. You may need to twist the screen slightly until it fits snugly in both grooves.
Step 7- Slip the rubber bumper back into place.
