Your Davey EcoPure 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 efcient performance from your Davey EcoPure 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 specically 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 EcoPure 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 inefcient
performance. Allow sufcient 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 specications), 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.

– 3 –
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. Connect barrel unions utilising O-Rings supplied on ttings and screw into the
multiport valve body.
10. Connect the pressure gauge to the air bleed port utilising the supplied O-ring on
the air bleed plug. Do not apply Telfon tape to the pressure gauge thread as it
may damage the valve.
CAUTION
• A non return valve is required between pump and pool on the inlet side.
• 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 Teon tape on all male threads. Piping should be independently supported and
not impose heavy loads on the lter or pump. Use 40mm or 50mm (11/2” 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. DEP2140, DEP2540
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. DEP2850, DEP3250, DEP3650, DEP4050
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.

Commissioning Filter
Refer to “operating instructions” below for safety warning and multiport valve
control prior to the lter start-up. The pool should be slightly overlled and the lter
backwashed and then run on RINSE to prevent dust and ne particles in the media
bed returning to the pool.
1. Backwash the lter for up to 2 to 3 minutes, then stop the pump.
2. Position the valve handle to “RINSE”.
3. Start the pump and run until the water in the valve sight glass becomes clear.
4. Stop the pump and position the valve handle to “FILTER”.
5. Start the pump. The Filter is now in ltration mode.
6. To determine the correct operating conditions, check the pressure gauge
reading is 80kPa or below. Record the clean operating pressure of your lter.
Operating Instructions
WARNING - FILTER OPERATES UNDER HIGH PRESSURE
• Ensure all lids / closures / clamps are correctly secured before
operating system.
• Never adjust clamps or change valve settings with the system
under pressure.
• Relieve all pressure from system before working on lter.
Multiport Valve Control
The ow of water through the lter is controlled by the multiport valve on the top
of the lter tank. The handle on top of the valve can be moved to any one of six
positions, which have the following functions:

– 5 –
Valve Position Function
FILTER Normal ltration and vacuuming through lter.
BACKWASH Clean the lter.
RINSE Used on initial lter start-up and after backwash to
prevent dirt in the sand returning to the pool.
WASTE By-passes the lter; used for vacuuming to waste, or
draining the pool.
RECIRCULATE By-passes the lter to circulating water to the pool or to
boost spa jets.
CLOSED Shuts off all ow to the lter. Do not run pump.
CAUTION:
Never shift the valve handle position while the pump is running.
This lter tank must not be operated under vacuum. Should leaf
baskets or suction lines become clogged, blocked or closed, lter
damage not covered by guarantee may occur (particularly if an
auxiliary pump is installed in line down stream of the lter).
Normal Filter Cycle
1. Set the valve to FILTER and start the pump.
2. With a clean lter, record the pressure gauge reading or mark the needle
position on the pressure gauge.
3. Operate the lter each day for a sufcient time to turn over the water in the pool
once every day. The lter should also be operated at all times the pool is in use and
for about one hour afterwards. During the winter, the running time may be reduced.
4. When the pressure gauge reading is 40 - 50kPa higher than the clean lter
gauge reading as in (2) above, it will be necessary to clean or backwash the
lter (see section on Backwashing the Filter).
Backwashing the Filter
When the lter gauge reading is 40 - 50kPa above the clean lter gauge reading,
cleaning or backwashing is required. To perform the backwash operation:
1. Shut off the pump. Be sure to disconnect any automatic Vacuum Cleaner.
2. Shift the valve handle to BACKWASH.
3. Start the pump and run until the water appears clean through the sight glass
(this will take two or three minutes).
4. Shut off the pump and turn the valve handle to RINSE.
5. Start the pump and run for approximately one minute.
6. Shut off the pump and turn the valve handle to FILTER.
7. Start the pump; a new lter cycle has now begun.
8. If a backwash cycle does not reduce the operating pressure of the lter, the
media will need to be changed. Contact your local pool shop.
CAUTION: Most lter media contains dust and ne particles that
must be backwashed from media before lter is set to ‘Filter’.
CAUTION:
Never vacuum while backwashing.

WARNING! Pump suction is hazardous and can trap and drown or disembowel
bathers. Do not block suction. Do not use or operate swimming pools, spas
or spa baths if a suction cover is broken, missing or loose. Two suction covers
and inlets must be provided into every pump to avoid suction entrapment.
Routine Maintenance tasks – to maximise the life of your pool equipment & personal
safety, use this checklist once a week. Turn pump off rst.
a. Make sure that any pressure gauges are in working condition and the operating
pressure is within limits as specied on the product.
b. Make sure that each suction inlet, and main drain has a cover that is securely attached
and in safe working condition.
c. Make sure that all skimmer covers are securely attached and in safe working condition.
These should be replaced every 3 to 4 years.
d. Remove any obstructions or debris from the main drain cover.
e. Ensure the skimmer baskets and the pump hair and lint pots are free of leaves and
debris at least once a week.
f. Remove obstructions and combustibles from around the pump motor.
g. Make sure all wiring connections are clean and that all wiring and electrical equipment
is in good condition. Damaged wiring must be repaired or replaced by a qualied
electrician as soon as damage is discovered.
h. Check water balance and sanitiser levels at your local pool shop.
Small children using the pool or spa must ALWAYS have close adult
supervision.
DANGER - Hazardous suction. Do not block water entry into ltration
system with any part of your body as the pressure can trap hair or body
parts, causing severe injury or death. Do not block suction. Turn off
pump immediately if someone becomes trapped.
Caution! Do not add chemicals directly to the pool skimmer. Adding
undiluted chemicals may damage pump and lter and void warranty.
To avoid explosion and possible severe or fatal injury, lter pressure must
not exceed 280kPa. Do not test lter with compressed air. Check that all
clamps and fasteners are in good condition and are rmly secured before
pressurising system. Never adjust clamps or fasteners while lter is
pressurised.
WARNING:
Always relieve pressure from system before performing any
service work.
