Introduction
Congratulations on your purchase of a high quality, Davey Aquashield Centurion
Ultra Violet water treatment system. All components have been designed and
manufactured to give trouble free, reliable operation.
Model Selection
Davey Aquashield Centurion units are selected according to the maximum water or
peak ow requirement. As it is not possible to overdose on UV treatment, the unit can
be oversized for the ow.
The system incorporates pre-ltration to ensure that particulate matter does not
shield micro-organisms from the UV light. In this system water ows through a 20um
lter, followed by a 1um lter for removal of sediments and cysts.
Aquashield Centurion 50W will effectively treat a water owing at a maximum rate of
50 litres of water per minute. Suitable for a single bathroom home.
Aquashield Centurion 70W will effectively treat a water owing at a maximum rate of
70 litres of water per minute. Suitable for a two story house with two bathrooms.
