AF9800 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.
AF9800 5. Initial Installation & Operation General The filter assembly is protectively packed with all parts assembled. Installation Take the filter assembly out of the wood platform. Install the filter assembly to the inlet line and outlet line. Connect a drainpipe to the hydraulic flushing valve outlet opening (at least 63 mm or 2”...

AF9800 Initial Operation Gradually open the inlet valve (make sure that the outlet valve, if installed, is open). Check the filter assembly and its connections for leaks. Perform a flushing cycle by disconnecting the low pressure tube from the differential pressure indicator (closing of the electrical circuit) – re connect it immediately as flushing start.
AF9800 6. Maintenance & Periodical Checks 6.1 – Electric Motor Removal & Installation Close the inlet and the outlet line valves. Set the main switch at the control panel to "0" position. Verify that filter is drained prior to service. A qualified technician will carry out the electrical connections.
AF9800 6.2 - Solenoid Removal & Installation The solenoid hydraulically controls the flushing valve's operation. 1. Remove the upper cover, disconnect and remove the 4 x 1.5V batteries. 2. Disconnect the solenoid control tubes. 3. Remove the fittings from the damaged solenoid. 4.
AF9800 6.3 – DP Indicator Removal & Installation The differential pressure indicator supplies data to the electronic control unit, which controls the filter's self-cleaning process. 1. Set the main switch at the control panel to "0" position. 2. Close the inlet and outlet valves of the filter and verify that filter is drained prior to service.
AF9800 6.4 – Hydraulic Piston Assembly Removal & Installation The hydraulic piston enables the linear movement of the dirt collector. Set the main switch at the control panel to "0" position. Close the inlet and outlet valves of the filter and verify that filter is rained prior to service.
AF9800 6.5 - Coarse Screen Removal & Installation 1. Close the inlet and the outlet line valves. 2. Set the main switch at the control panel to "0" position. 3. Verify that filter is drained prior to service. 4. Remove the nuts and washers attaching the cover to the filter housing. 5.
AF9800 6.6 - Fine Screen Assembly Removal & Installatione 1. Close the inlet and the outlet line valves. 2. Set the main switch at the control panel to "0" position. 3. Verify that filter is drained prior to service. 4. Remove the nuts and washers attaching the cover to the filter housing. 5.
AF9800 6.7 - Dirt Collector Removal & Installation 1. Close the inlet and the outlet line valves. 2. Set the main switch at the control panel to "0" position. 3. Verify that filter is drained prior to service. 4. Remove the nuts and washers attaching the cover to the filter housing. 5.
AF9800 6.8 - Periodical Checks Perform yearly Periodical Checks at the beginning of the season, according to the following instructions: 1. Check the condition of the coarse screen. If defective, replace according to "Coarse Screen Removal & Installation". 2. Check the condition of the fine screen assembly. If defective, replace according to "Fine Screen Assembly Removal &...
AF9800 8. Appendix 8.1 –ELI 02 Controller & Electrical Wiring ( V-08-2019) Warning - Do not operate the system without checking the motor rotation. Summary of Abbreviations DP = Differential pressure switch which measures the differential pressure across the filter, And activates the flushing mechanism above a set point. (Normally set to 0.5 bar) SV = Flushing solenoid , Which activates the flush filter hydraulic mechanism.
