Filter Installation
•
Before lifting this unit we recommend a full risk assesment be conducted, taking into account the balance on
the unit and potential stress and damage, which may be caused to pipework by unsupported lifting.
• Place the filter in its final position ensuring the location is stable, level and suitable for the support of the
system’s operational weight. Installers should ensure suitable access is available to dismantle top flange of
the unit to carry out any media loading or maintenance that may be necessary. Check this by removing and
refitting top flange. (Filter is pre-loaded with media prior to dispatch).
• Check for all round access allowing at least 1m in all directions for ease of access. In restricted locations
please refer to factory before fixing in place in any areas that are adjacent to fixed objects. Once these
criteria are satisfied, secure the filter down.
• The filter may be located inside or outside, but if an outside location is chosen, care should be taken that the
filter is not subjected to ambient temperatures of below +2 ° C without heat tracing. If there is any risk of this,
you should consult with Amiad Water Systems.
• Connect inlet/outlet process pipe-work, backwash and drain to the unit as necessary and check all filter
connections for tightness, as fittings may become loose during transit. Remember not to overtighten the
connections.
• If the control panel doesn’t come pre-mounted, mount it adjacent to the filter unit. The control panel should
be located so as not to come into direct or sustained contact with water. The panel has an IP rating of IP65.
Client Scope of Supply
• An incoming electrical supply suitable for a control panel.
• A suitable pipe-work for connecting the filter via V1, V2, V3, V4.
• Note that pipe-work interface V4 must allow a flow under gravity without any obstructions (2-10m max).
• A gate valve on the outlet pipe-work to adjust the process flow (Downstream V2).
•
A gate valve on the drain pipe-work to adjust the backwash flow (Downstream V4).
•
An isolation valve on the inlet & outlet process supply is recommended as good engineering practice.
• A by-pass to allow for filter maintenance offline is a good engineering practice and strongly recommended.
• All pipe-work should be fully supported to ensure no undue mechanical stress is placed on the filter.
