INSTALLATION
Design recommendations
1. The filter requires 5.7m3/h (25USgpm) for flushing, in addition to the working flow rate at a
minimum pressure of 1.5 bar (22 psi). In the event that the system cannot provide the flushing
flow in addition to the working flow, at the minimum required pressure, a hydraulic valve should
be installed downstream of the filter. This valve will be closed during the flushing process in
order to ensure sufficient cleaning.
2. Do not allow water to flow in opposite direction. In case that there is a chance of back flow a non-
return check valve should be installed downstream of the filter.
Installation instructions
1. Install a manual valve upstream of the filter in order to enable convenient maintenance.
2. The diameter of the inlet pipe must not be smaller than that of the filter inlet.
3. Install the filter in a way that enables convenient approach and enough space to dismantle the
filter for maintenance purposes.
4. It is recommended to install the filter horizontally, especially if the water contains sand.
5. Ensure the direction of flow is according to the arrows marked on the filter housing.
6. The exhaust valve can be facing downwards or sideways. Connect a minimum of 1.5" (40 mm)
pipe to the exhaust valve using a detachable connector or a flexible pipe. The exhaust pipe
should be designed so that it creates minimal resistance to the flow of 5.7m3/h (25USgpm).
7. If the system is designed to operate with a working pressure higher than 6 bar (85 psi), it is
recommended that a manual valve will be installed on the exhaust pipe, in order to enable
regulation of the flushing flow rate.

START- UP AND FIRST OPERATION
1. Set the controller to 16 seconds flushing time and 2-4 hour intervals.
2. Operate a "dry" flushing cycle. Verify proper operation of the controller, the motor and the
solenoid valve.
3. Open the inlet valve to the filter, while the outlet valve remains closed or with an open by-pass
valve (This will keep the flow in the filter at a minimum), and operate a flushing cycle by
pressing the push-button on the controller panel.
4. Make sure the exhaust valve opens and all stages of the flushing cycle are carried out. Attend to
leakage, if any.
If necessary, change the time setting to ensure complete up and down motion of the suction
scanner.
5. Gradually open the outlet valve and/or close the by-pass valve. Operate the filter at the
designed hydraulic conditions.
