Installation
Read these instructions carefully before installing and operating the filter.
Design Recommendations
If a prolonged pipeline fill time causes a temporary high flow and low pressure situation, it is 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.
The upstream pressure source should not drop below 30psi (2bar) during the rinse cycle. If this cannot be ensured,
consult the manufacturer.
If continued water delivery is essential even during “down time” maintenance periods, it is 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.
Avoid placing the drainage pipe on a rising slope to minimize backpressure.
Secure the open end of the drain pipe to prevent movement during the rinse cycle.
It is recommended to install a mechanical non-return valve downstream of the filter to prevent backflow damage to
the screen.
It is recommended to install a pressure gauge on the three-way valve.
Check that there is sufficient space to remove the lid assembly and the screen from the filter for troubleshooting.
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 Procedure
Ensure the direction of flow is according to the arrows marked on the filter housing.
1.
Connect a minimum of 3" (75 mm) pipe to the exhaust valve. The exhaust pipe should be designed so that it creates
minimal resistance to flow of 20m3/h (88 US-gpm). Water should be allowed to flow to atmosphere freely from the
exhaust pipe.
2.
Connect a minimum of 1" (25mm) flexible tube to the rinse controller drain port. Ensure this drain line is open to
atmosphere.
IMPORTANT!!
Prevent static back pressure or reverse flow through the filter.
Install a manual or a hydraulic valve downstream of the filter.
NOTE:
The filter may enter flushing mode automatically, without prior warning.
