1. Introduction
General
YAMIT Filtration & Water Treatment Ltd. (hereinafter YAMIT) congratulates you on
purchasing the new AF-9800 SERIES self-cleaning filter. This filter now joins the wide
family of filters produced and supplied by YAMIT or agriculture, municipal water and
sewage systems, and all types of industrial applications. All products manufactured by
YAMIT are easy to install, use and service and don’t require special skills to operate
them.
For operation and maintenance of the filter please follow the instructions in this
manual.
2. Safety Instructions
1. It is necessary to use a noise protection device while the filter is in operation.
2. In the model with 12V DC power supply use the device which is provided by
YAMIT or equivalent (with certifications and power rating).
3. Verify that the control panel is grounded. Also verify that the AC power cord is
connected to the control panel through 3 x 6A-fuse protector.
4. Verify that the filter housing is grounded to the appropriate location.
5. Confirm AC power disconnection prior to service.
6. Confirm filter draining prior to service.
7. Take precautions while lifting, transporting or installing the filter.
8. Installation and operation of the filter should be performed so as to avoid direct
water splashing on the control unit.
9. Confirm that filter weight, when full, meets the support construction
requirements.
10. Prior to installation confirm line pressure matches filter’s operational pressure.
11. During installation, use standard flanges and connections only.
12. Check that all filter flanges bolts are properly secured.
13. Please note, the filter enters a flushing mode automatically, without prior
warning.
14. Use original parts only, while servicing the filter.
15. No changes or modifications to the equipment are allowed.

Filter Assembly General Description
The AF-9800 Hydro electric self-cleaning screen filter enables high quality
filtering at filtering degrees of 10-3000 micron from different types of fluid
sources such as sewage, reservoirs, rivers, lakes, and wells.
The AF-9800 SERIES filter contains the following parts:

Filter Operation General Description
Filtration
Water enters the filter through the “Inlet” (1) and passes through the coarse
screen (2) that functions as a “first stop” for rough particles. Water then
reaches the fine screen (3), which further purifies the flow by separating
smaller particles from the water. As more water flows through, impurities
build up on the fine screen. As impurities on the screen accumulate, a
pressure imbalance is built up between the internal section of the fine screen
(3) and its external section.
Cleaning Process
When the difference in pressure (ΔP) reaches the preset value on the
differential pressure indicator, Or when the preset time in the controller
arrives, a series of events is triggered while water continues to flow to the
system units. The controller transmits a signal for a 15 second flushing cycle.
The solenoid opens the flushing valve (4), and release the pressure from the
hydraulic piston (5). Water flows outside from the flushing valve (4). Pressure
in the hydraulic chamber (6) and the dirt collector (7) is significantly lowered
resulting in a suction process via the suction nozzles (8) to the dirt collector (7)
and from there to the hydraulic chamber (6) through the flushing valve (4)
outside. The electric motor (9) simultaneously rotates the dirt collector (7)
around its axis. The pressure is released from the piston (5) and the high
pressure inside the filter causes linear movement of the dirt collector. The
combination of the linear movement and rotation efficiently cleans the entire
internal screen (3) surface.
At the end of the 15 second cycle the flushing valve (4) closes and the
operation of the electric motor (9) is stopped. The increased water pressure
returns the hydraulic piston (5) to its initial position. The filter is now ready for
the next cycle, with clean and filtered water flowing through the “Outlet” (10).
The 15 second flushing cycle resumes operation whenever the difference in
pressure reaches the preset pressure value set on the differential pressure
indicator. Or when the preset time in the controller is triggered on. If the
pressure difference remains unchanged after one cycle, another cycle will start
after a delay of 10 seconds
