Page 3: Introduction
Model Selection Davey Aquashield Centurion units are selected according to the maximum water or peak flow requirement. As it is not possible to overdose on UV treatment, the unit can be oversized for the flow. -
Page 4: Installation
Choosing a Site To protect your Davey Aquashield Centurion from the weather, make sure the site is water proof, frost free and has adequate ventilation. Choose a site with a structurally appropriate mounting position on the wall. -
Page 5: Mounting, Plumbing And Start-Up
Mounting, Plumbing and Start-up The unit has 25mm BSP plumbing connections. The inward side has a 25mm female connector and requires male plumbing. The outward side has a connector that requires either 25mm female plumbing OR 20mm male plumbing. – Use the mounting template to mark the position of holes required for mounting. Fix screws to the wall that will allow the Aquashield Centurion to be mounted using the key-holes in the back of the unit. -

Never use PVC pipe directly connected to unit. PVC pipe and fittings can be used after 90º metal elbows are connected to the inlet and outlet of the chamber eg. brass fittings. Larger diameter pipe may be used to minimise resistance to flow, but maximum flow rates should not be exceeded, as correct water treatment cannot be assured at higher flows. -
Page 7: Maintenance
Maintenance Cleaning the quartz sleeve – 3 monthly (or more often if used with hard water). If dirt is allowed to build up on the quartz sleeve it will impair the UV output. The quartz sleeve should be removed after one month and inspected for deposits. –... -
