INSTALLATION
Pre-installation preparations
Design Recommendations
If a long pipeline fill time causes a temporary high flow and low pressure situation, it is recommended to
install a pressure-sustaining valve (PSV) downstream from the filter. The PSV will ensure a controlled
fill-up of the line.
It is highly recommended to install isolation valves upstream and downstream from the filter for
maintenance and troubleshooting purposes.
In case a PRV is required, it is highly recommended to install it downstream from the filter.
It is highly recommended to install a mechanical non-return valve downstream of the filter to prevent
backflow damage to the screen.
Make sure that the filter location offers sufficient clearance to remove the cover assembly and the
screen assembly from the filter for troubleshooting (see page 8).
Avoid placing the flush pipe on a rising slope to prevent backpressure.
Flush pipe diameter: Minimum 2".
Preparations for Installation
Prepare the inlet and outlet pipes according to the dimensions and type of connection (thread/flange) of
your filter (see page 9).
Ensure suitable lighting at the area of the filter to enable good visibility and safe maintenance.
Arrange suitable platforms and safety barriers to enable easy, safe access to the filter.
Allow a convenient access and adequate space arround the filter for dismantling and maintenance.
