Your Davey Crystal Clear Media Filter
Congratulations on your purchase of a quality product from the Davey Water
Products range of Pool and Spa Equipment. You are assured of many years of
reliable and efficient performance from your Davey Crystal Clear
® Media Filter
backed by Davey’s Ten Year Tank Guarantee and Two Year Valve Guarantee.*
*Refer to guarantee statement 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.
Notice to Users and Installers – 18” to 25” models
Your new Davey Crystal Clear ® Media Filter combines two types of media filter
construction to provide exceptional tank strength – an inner moulded polyethylene
(PE) tank supported by a strong outer layer of spun-wound fibreglass.
You may notice some seepage of water and air from the filter tank upon initial
usage. This is NOT a leak, but simply trapped air and water being expelled from
between the inner PE tank and the outer layer of fibreglass while the tank is
subjected to pressure.
Water deposits (from rain, pool splashing and condensation) between the internal
tank and the outer fibreglass layer are considered normal and will not affect the
performance of the filter or the pool filtration system. Please be aware that this
seepage will disappear once expelled.
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 and 150mm clearance is required behind the pump for pump cooling.
