Installation Manual V3 04/18
Installation Advice
• At least 50mm (2”) vertical clearance
must be allowed for the filter bowl (to
facilitate servicing).
• The water flow meter can be installed
anywhere on the side-stream loop or,
if necessary, on adjacent common
pipework. It must always be mounted in
the same water flow as the anode unit.
• Use a NRV (non-return valve), “¼ turn”
isolating valves and drain valves as shown
in the schematic diagrams.
• All pipework and fittings should be
assembled to facilitate easy access for
maintenance.
• Pipework earthing must comply with the
latest electrical safety regulations.
PRINCIPLE INSTALLATION GUIDELINES
• Mechanical connections to the anode
unit and water flow meter must be
demountable to facilitate the servicing of
both units.
• There must be at least three metres of
direct pipeline between the anode unit
and the plant. Additional pipework should
be added (as a coil or serpentine) to
ensure this is achieved.
• The equipment should always be installed
as a side-stream to the main water feed-
line so that it can be easily isolated for
maintenance.
• The filter must always be installed
upstream of the anode unit.
• If the anode unit can be placed on the
in-coming water main then the whole
building will benefit from the protection
the unit can provide.
• The single bowl filter orientation must
always be vertical. Ensure, however, that
the orientation is such that the bowl
sits ‘below’ for sizes 1", 1¼" and 1½"
and ‘above’ for 2". The 2" size has a drain
valve into the pipework body part for ease
of maintenance.
