Page 9: Description Of Filter Operation
The SAF-4500 is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by an electric motor. The SAF-4500 is designed to work with various types of screens in filtration degrees from 10 to 500 micron, and is available in 4", 6" and 8" inlet/outlet diameter. - Page 10 Initiation of self-cleaning: The filter initiates the self-cleaning process under any one of the following conditions: 1. PD flush - The Pressure Differential Switch (PDS) closes a free potential contact signal when the pressure differential across the screen reaches the pre-set value (usually 0.5 bar =7 psi). The control board registers the signal and activates the flushing cycle.

Page 11: Installation
INSTALLATION Design recommendations: 1. Often, flow increases and pressure drop dramatically during fill-up of a water system. In this case, a pressure-sustaining valve installed downstream of the filter will ensure the minimum required pressure for the filter and a controlled filling-up of the line. - Page 12 Start-up and first operation 1. Make sure all the electric wiring is correct, according to the enclosed drawings. 2. Switch ON the control & 24V circuit breakers and the motor protector O.L. The motor will start operating *. 3. CHECK ROTATION: The suction scanner shaft should turn clockwise (CW) and move towards the filter housing until it reaches limit switch "A".

Page 13: Maintenance
MAINTENANCE General inspection Initiate a flush cycle by closing the 1/4" valve at the low pressure sensing port of the pressure differential switch for 5 seconds. Check that the exhaust valve opens, that the scanner moves properly, and when it reaches the limit switch - verify that the exhaust valve closes. - Page 14 Cleaning the coarse screen: 1. Close the filter inlet valve. 2. Release pressure from the filter by performing a flush cycle. 3. Remove the service lid (24) by disconnecting the bolts (26) from the nuts (28) 4. Clean the coarse screen: - To remove large particles insert your hand into the coarse screen area.

DISMANTLING AND ASSEMBLING THE FILTER COMPONENTS Prior to opening the filter perform a flush cycle by pressing the "TEST" push button. The Fine screen Dismantling: 1. Close the filter inlet and outlet valves and release the pressure. 2. Release the lid bolts (23) from their nuts and remove the lid (21). 3. - Page 17 The drive shaft housing and coarse screen: Dismantling: Close the inlet and outlet valves of the filter and release pressure. Disconnect power supply from the control board. Dismantle the suction scanner and fine screen as described previously. Pull out the plug from the solenoid coil (60). Remove the limit switch sling (6 on page 22) from the drive shaft housing by unscrewing the bolts (14 on page 22).
