Rain Bird filtration equipment has been designed to filter water, in accordance with the operating
conditions outlined in this manual and the label on the equipment.

• Rain Bird filtration systems are NOT designed for the filtration of hazardous liquids (such as those
specified in section 2 of article 2 of the Executive Committee 67/548/CEE, 27th June 1967) or liquids
for food use.

• This equipment has been designed and manufactured to satisfy the requirements communicated to
the manufacturer by the customer. Any change in its use could cause damage not covered by the
warranty.

• Save this manual so the user of the equipment can familiarize themselves with it.

• These are general instructions for safe operation of the equipment. These instructions are not a
complete list; the user must adopt as many security measures as necessary to guarantee their
safety.

• Follow the instructions described in this manual.

• Do not open the filter clamp when the equipment is pressurized, it could cause serious injury to
people, the equipment or to the surrounding area.

• Do use adequate personal protective equipment (proper working clothing, safety glasses, steel toed
boots and other elements of personal protection).

• Determine the chemical compatibility between the equipment's materials and the characteristics of
the water to be filtered.

• Before using the equipment, make sure that all the covers are properly closed and the connections
are in good condition.

• Make sure that the equipment is depressurized by reading the gauges (0 PSI) on the filters inlet and
outlet manifold before exposing the interior of the equipment to atmosphere (before opening any
filter, removing any coupling, etc.)

• Do not forget to close the safety lock on the clamp. It will prevent its accidental opening.

• Do not exceed the maximum pressure or operation intervals (pressure, temperature, PH, and flow
rate) indicated in the Technical Data.

• In freeze areas, empty the filtration system to prevent damage.

Thank you for selecting a Rain Bird HDF 1X2 Disc filtration system. Please read this manual
carefully as it will help you find answers to most of your questions.

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.

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.
