Carefully replace the
Hydraulic Motor
and
Plate
into the
Filter Housing
, ensuring that
the
Piston Shaft
is inserted into the hole in the middle of the
Inlet Disc
.
22.
Push down firmly on the
Plate
. When correctly in place the
central collar
of the
Plate
will be flush with
the top of the
Housing
. Make sure the
Shaft
can move up and down, and rotate / spin freely.
23.
Ensure the rubber
Filter Cover O-ring
is in place in the
Cover
24.
Replace the filter cover assembly on to the filter
Housing
, rotating the
Cover
slightly to seat the
O-Ring
25.
Replace and fasten the
Clamp
WARNING
Use caution when fastening the clamp, avoid injury to your fingers
26.
Re-connect the Drain pipe to the Drain valve assembly
27.
Reinstall the
Piston
, making sure the
O-Ring
is in place on the Piston thread. Rotate it clockwise
by hand only – as per
3.4.1 Backwash Controller Installation,
do not use any tools.
28.
Re-attach the
1/4” Plastic Tubing
into the
Piston
– push in hard.

5.2 Piston Maintenance
The piston shaft requires lubrication on a quarterly schedule.
1.
2.
Remove the
1/4” Tubing
from the push to connect fitting on the top of the
Piston
.
3.
Unscrew the
Piston
(counter clockwise)
4.
A silicon grease should be applied to the
Piston Shaft
which should be cycled in and out a few times to get
the grease distributed to the inner O-ring seal. Two applications of grease and cycling is adequate.
5.
The
Piston
may drip water from the lower vent hole. This is normal during the course of operation.
If the lower vent hole continually flows water, the piston should be replaced.
5.3 Winterization
If you have unions on the inlet and outlet, storing the HN-G Filter in a room that is above freezing (and will not freeze) is the best way to
winterize it. This would minimize the thoroughness required of the steps below (but still recommended before storage).
1.
Run a cleaning cycle by pressing the M button on the Filtron 1-10 (
HN-G-01-1-XXX, HN-G-02-1-XXX
models) or
from the irrigation controller (
HN-G-01-2-XXX, HN-G-02-2-XXX
models),
, empty completely.
2.
Empty the
Piston
of excess water by removing it and then cycling the Piston Shaft in and out. Lubricate the piston
shaft with silicone grease and cycle the shaft in and out a few times while adding grease each time (the idea is to
get the grease to the lip of the internal seal). Store the piston in a plastic zip lock so the water does not completely
evaporate (keeps the seals lubricated). It is best to store the piston inside and block off the hole in the filter cover.
3.
Blow out all of the ¼” and 5/16” control tubing.
4.
Gently blow out each side of the DP switch on the controller (remove the 5/16” tubing at the red and black connectors).
5.
Unscrew the solenoid on the 1” Rinse valve (
) and make sure that any excess water is removed from the diaphragm
