3. INTRODUCTION

4.1 Filtration Phase

In the filtration phase, water is carried from the inlet
manifold, through the backflushing three-way valve
(valve 1), to the interior of the filter through the inlet.

Once the water enters the filter, the only paths for it to
follow are the channels of the discs. The particles are
trapped by the channels in the discs.

The stack is compressed by the spring action and the
hydraulic power itself.

The filtered water goes through the 2” hydraulic valve
and proceeds through the rest of the installation. The
outlet manifold is responsible for collecting the filtered
water and carrying to the exterior.

Rain Bird HDF 1X2 Disc Filters consists of a filtering element comprised of grooved discs that allows
the retention of particles of a size larger than the required filtration grade. The equipment combines the
advantages of the disc filters with those of the helico-centrifugal effects of the Rain Bird HDF 1X2.

The system carries out two independent phases, one called the FILTRATION PHASE and the other
called the BACKFLUSHING PHASE.

4. HOW IT WORKS

Thanks to the filters helico-centrifugal effect, the number
of backflushings are dramatically reduced, minimizing
water consumption.

This is achieved by the patent-pending design located on
the base of the cartridge.

7

4.2 Backflushing Phase

Through the feeding of the three-ways valves
chamber, the inlet of water to the filter closes,
beginning the inner of the filter with the drainage
manifold, thus starting the backflushing cleaning.

The filtered water given by the Special backflushing T,
is introduced in the filter.

The available hydraulic power is used to overcome the
pressure exerted by the spring on the discs stack,
generating a decompression due to the piston
displacement (raising).

The release of the discs creates rotation due to the
tangential projection of the water coming from the
feeder bars which at the same time are used as a
structural shoulder for the discs stack.

The end of the backflushing coincides with the closure
of the drainage outlet and the opening of the outlet
manifold, allowing water coming from the feeder
manifold to come into the interior of the filter. This
allows the systems to re-establish the filtration phase.

5.2 Product Labeling

The equipment is identified by two labels, one is placed on one of the main
manifolds, the other is placed on the filters.

The modification or elimination of this
label voids any warranty; and impedes

1. Unpack the equipment carefully and check that there no is no evident damage.

2. Confirm that all installation parameters are met in accordance with those of the equipment.

3. You can modify the height of the equipment with the adjustable supports. Once the supports
are in place adjust their height as required. Due to the equipment dimensions, the shoulders
height should be adjusted so that, the upper part of the drainage manifold is placed at a
distance of 33,2" (843 mm) from the ground. The separation between the shoulders should be
560 mm.

4. Screw the stainless steel bushing to the outlets of the three-way hydraulic valves. It is very
important to use sealer in the threads of both bushings.

5. Assemble the equipment, connecting the inlet, outlet and drainage manifolds using their
connections.

6. Install a glycerin pressure gauge 0-145 psi (0-10) bar to measure the pressure coming into the
valve. It is recommended you use liquid sealer or LOCTITE 5331, but not in excess.

7. Place the 2” NPT Cap in the open outlet of the filter base. The cap does not need sealing
because it is provided with an o-ring.

8. Place the cartridge in the filter base. Once this is completed, place the lid on the unit and close
the clamp.

9. Check all connections of the equipment and secure the base to the ground in order to avoid
vibration.

To close the filter check for debris on the 0-ring in the base. Carefully install the lid and close the
filter clamp. To close the clamp, place the bolt in the grooved seat and adjust the lever then
clamp the anti-opening device and thread the saftey screw without forcing it.

6.4 Securing the Equipment

Before securing the equipment to the ground, verify that
the equipment is level. Secure the equipment to the
ground using the appropriate type screws or bolts for the
type of ground the equipment will be resting on. The
screws should be placed in the 10 mm diameter
manifold holes.

6.5 Connection of the main manifolds, inlet, outlet and drainage

The main manifolds connections (inlet and outlet manifolds) are grooved. Use the supplied
accessories (as required) to connect the equipment to the rest of the system.

The drainage manifold has a PVC grooved coupling from factory that glues to a 3” PVC pipe.
Connect the inlet, outlet and drainage manifolds with its corresponding connections.
