Pipework Connections
• The waste /dirty backwash water V4 connection, should not create any back-pressure on the filter. The
drain pipe-work should be kept to a minimum of 2 meters and have a minimum of bends. It should not
rise above the filter outlet. The drain line should be of a minimum 2” diameter or larger and not exceed
10 meters in length. If a greater drain length is required, it should be done via a tundish arrangement
breaking any back pressure build up. A suitable valve (gate type) is required to allow flow regulation.
•
Backwash water V3 supply to be connected to the backwash pump outlet. It is recommended that an
isolation valve be installed to facilitate valve maintenance/removal.
• Make sure that the HP (inlet) and LP (outlet) connections on the filter are connected to the differential
pressure switch.
Electrical Connections
• Electric wiring must be performed by an authorized electrician only, using standardized and approved
components.
•
Install a lockable main power cut-off switch close to the control panel.
•
If due to site constraints, the control panel is installed without a clear line of vision to the filter, an
additional lockable power disconnect cut-off switch should be installed near each filter unit.
• The filter should be installed in a manner in which the electrical components and/or the control panel are
protected from direct contact with water.
•
Always ensure all connections to the panel are made with suitable cabling and glands. Under no
circumstances should the equipment be hooked up temporarily.
• Check all panel connections are tight and that no components have become dislodged in transit.
• Connect a suitable (per specification) incoming supply to the control panel.
• Connect to ground as per the diagram and isolate any earth bonding of the filter as required.
