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 efcient performance from your Davey Crystal Clear Media Filter
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 specically designed for the ltration 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 rst consulting your Davey Dealer or Davey Water Products Pty Ltd.
The Crystal Clear Water Difference
Media ltration is nature’s own proven method of ltration. Pool water enters the
lter 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 ow decreases. When the pressure reaches
an unacceptable level, the ow must be reversed to clean the lter media bed in a
process called “backwashing” which discharges the dirt to waste.
Installation Location
The lter should be placed in its permanent location, preferably as close to the pool
as practicable. Position the lter 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 inefcient
performance. Allow sufcient space around the lter for routine maintenance and
provide for adequate lter drainage and pump ventilation.
Place the pump in position on the slab and locate the lter 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 ltration system is adequately protected from the weather. For proper
care and maintenance of your lter, see section on “Filter Care”.
Assembly
1. Undo the V-band clamp or ange 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 ll 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 lter opening.
6. Pour the correct amount of media into the tank (refer specications), evenly
distributing it around the central pipe. Level out the top of the media bed.

7. Remove the sand guide and all traces of media from the tank ange.
8. Ensure the closure o-ring is clean and in the correct position. If necessary, apply
a thin lm of oring lubricant to the o-rings. Assemble the multiport valve to the
tank aligning the ports to the appropriate plumbing.
9. Apply Teon tape to the thread on the pressure gauge and barrel unions and
screw into the multiport valve body. 7 turns of tape is required.
CAUTION
• A non return valve is required in between the pump and lter.
• On installations where the waste line is more than 3 metres below pool
water level and more than 12 metres in length, a vacuum break valve
must be tted in the waste line close to the lter.
• If an auxiliary pump is installed in line downstream of the lter, it should
be protected against causing negative pressure in the lter tank. A ow
or pressure switch which only enables the auxiliary pump to run when
the main lter pump is running will achieve this.
• If the pump and lter are located below pool water level, it is necessary
to t isolating valves in the pipe between the pump and the skimmer
box and in the return pipe from the multiport valve to the pool. This
prevents water draining from the pool during maintenance.
FAILURE TO COMPLY WITH THE ABOVE CAUTIONS MAY RESULT IN FILTER
DAMAGE NOT COVERED BY THE GUARANTEE.
Pipe Connections
Use Teon tape on all male threads. Piping should be independently supported and
not impose heavy loads on the lter or pump. Use 40mm or 50mm (1
1
/2” or 2”) pipe
from the pump to the skimmer box, return pipe for the multiport valve to the pool and
from the multiport valve to the drain.
DO NOT OVERTIGHTEN
The ttings and multiport valve on this product are constructed of
ABS. Some PVC jointing compounds are incompatible with ABS.
Check compound suitability before use.
For models that use the 40mm (1.5”) valves, i.e. DCC2140, DCC2540
If the pipe length in the installation, is less than 15m, use the supplied 40mm barrel
unions as provided with 40mm PVC pipe.
If the pipe length in the installation is greater than 15m, 50mm PVC pipe is
recommended and the supplied unions should be adapted to suit. 50-40 reducing
adapters will need to be purchased at your local building/plumbing supplier.
For models that use the 50mm (2”) valves, i.e. DCC2550, DCC2850
It is recommended to use 50mm PVC pipe, regardless of the length of the pipe.
50mm barrel unions are provided with the multiport valve for connection of PVC pipe
to “pump”, “pool return” and “waste”
NOTE:
Ensure pipework is connected to appropriately labelled multiport
valve connections.
