backed by Davey’s Ten Year Tank Guarantee and Three Year Valve Guarantee.*
*Refer to guarantee statement on page 8 for full details.
Davey Media Filters have been specifically designed for the filtration of swimming
pool water in conditions set out in the Australian Standard for swimming pool water
quality (AS 3633) or equivalent. They should not be used for any other purpose
without first consulting your Davey Dealer or Davey Water Products Pty Ltd.
The Crystal Clear Water Difference
Media filtration is nature’s own proven method of filtration. Pool water enters the
filter and passes through graded media where the suspended particles are trapped
and the water is returned to the pool. As the build-up of dirt in the media increases,
so the water pressure rises and the flow decreases. When the pressure reaches
an unacceptable level, the flow must be reversed to clean the filter media bed in a
process called “backwashing” which discharges the dirt to waste.
Installation Location
The filter should be placed in its permanent location, preferably as close to the pool
as practicable. Position the filter tank and pump on a level concrete slab or similar
base with minimum dimensions of 900mm x 600mm (3’ x 2’). Do not use sand to
level the concrete slab, as it may wash away and cause vibration and inefficient
performance. Allow sufficient space around the filter for routine maintenance and
provide for adequate filter drainage and pump ventilation.
Place the pump in position on the slab and locate the filter tank alongside with the
multiport valve “PUMP” port oriented toward the pump.
A minimum clearance of 400mm above the multiport valve is required to permit easy removal.
Weather Protection
Davey Media Filter tanks are made from UV stabilised materials. However to
ensure years of reliable service, it is recommended that every effort be made to
ensure the filtration system is adequately protected from the weather. For proper
care and maintenance of your filter, see section on “Filter Care”.
Assembly
1. Undo the V-band clamp or flange nuts and remove the multiport valve.
2. Look inside the tank and ensure the laterals are secure inside the hub assembly
and that the stand pipe is inserted with the o-ring correctly into the under drain of
the valve.
3. Half fill the tank with water to provide a cushion for the media.
4. Make certain the under drain assembly is correctly located onto it’s stand at the
base of the tank.
5. Place the sand guide in the top of the filter opening.
6. Pour the correct amount of media into the tank (refer specifications), evenly
distributing it around the central pipe. Level out the top of the media bed.
