Installation
Design Recommendations

The inlet and outlet pipes must be the same or a larger diameter than the inlet and outlet diameters of the filter.

The upstream pressure source should not drop below 30 psi (2 bar) during the rinse cycle. If this cannot be ensured, consult the
manufacturer.

If a prolonged pipeline fill time causes a temporary high flow and low pressure situation, it recommended that you install a
pressure sustaining valve downstream of the filter. The pressure sustaining valve will ensure a controlled fill-up of the line.

If continued water delivery is essential even during “down time” maintenance periods, it recommended that a manual or
automatic by-pass be installed, and that isolating valves be installed up and downstream of each filter unit for isolation purposes.

Shut off valves must be installed in the inlet and outlet lines to enable maintenance.

A non-return valve should be installed where water hammer or back flow may be a problem.

The filter must be installed in the direction of flow indicated by the arrow on the filter body.

Secure the drain pipe so that there is no movement during flushing.

The highest point of the drain pipe should be no more than one half meter above the filter.

The drain pipe must allow free flow and be free of restrictions.
Preparations for Installation

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 approach and enough space for dismantling and maintenance.
Installation Instructions

Ensure the direction of flow is according to arrows marked on the filter housing

Install a drain valve in place of one of the pipe plugs in the inlet or outlet pipe on the installation manifold.
Important!

Prevent static back pressure or reverse flow through the filter.

Install a manual or a hydraulic valve downstream of the filter.

The filter may enter flushing mode automatically, without warning.
