INSTALLATION
Design recommendations
1. The filter requires 4 m
3
/h (26USgpm) 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 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 4 m
3
/h (26USgpm).
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, to enable regulation of the flushing flow rate.
