Weather Protection
Davey Cartridge Filters are constructed of corrosion resistant materials.
However, to ensure years of reliable performance, it is recommended that
the ltration system is adequately protected from the weather.

Davey Cartridge Filters provide economy, high performance and convenience in a well-designed pressure lter. The polyester element can be removed quickly for rinse cleaning without water loss. Davey Cartridge Filters
feature large lter areas which ensure even water distribution, peak ltration
performance and longer lter cycles.
The corrosion-resistant construction of Davey Cartridge Filters provides
long-life and durability. Davey Cartridge Filters are capacity matched with
Davey pool pumps forming a total pool ltration system that lasts and lasts.
Davey Cartridge Filters are also very suitable for use with other pool pumps.
Take care to match the pump and lter capacities to gain maximum performance and efciency.
The Sparkling Clear Water Difference
Cartridge ltration is an effective trouble-free proven method of ltration.
Pool water enters the lter and passes through a polyester element car-
tridge. Suspended particles are trapped and the water is returned to the
pool. As the build-up of dirt in the element increases, so the water pressure
rises and the ow decreases. When the pressure reaches an unacceptable
level, the element must be removed and cleaned. (Spray washing with a
common garden hose is generally sufcient).
* Refer to guarantee statement for full details
Installation and Operating Instructions 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. Allow sufcient space around the lter for routine main-
tenance and provide for adequate ventilation and drainage.
Pipe Connections
Piping should be independently supported and not impose heavy loads on
the lter or pump. Use 40mm or 50mm pipe for pump and pool return lines.
50mm should always be used if length of piping is over 15m.
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 pool, and in the
return line from the lter to the pool.
Barrel unions need to be hand tightened on. No sealant, glues or
silicones are required.
1. Pump to the Filter
Davey Cartridge Filters are equipped with two inlet ports marked ‘INLET’.
Select the inlet port most suitable for the installation and plug the other
inlet port with the blanking cap provided. Using quick connect couplings,
connect the pool pump delivery piping to the selected inlet port. Tighten by
hand only. Ensure the oring on the tting is clean, lubricated with oring lubricant and in the correct position.
2. Filter to Pool Return
Using quick connect couplings, connect the pool return piping to the lter
tting marked ‘OUTLET’. Tighten the tting by hand only. Ensure the oring
on the tting is clean, lubricated with oring lubricant and in the correct posi-
tion.
Place the pump in position on the slab and locate the lter alongside with
the appropriate pump inlet connection oriented towards the pump. Refer to
the specication section for the minimum clearance measurements required
for each model.
The lter base is provided with four mounting holes to enable it to be secured, if required.

Filter Operation
1. Make sure the pump is primed according to manufacturer’s directions.
2. Be sure all valves are open on suction and discharge lines. Ensure
the air bleed valve on the lter lid is open and the lid lock ring is in
place and secure.
3. Start the pump. Close the air bleed valve when water is expelled.
4. To determine the correct operating conditions with a clean lter, check
that the pressure gauge reading is 80kPa or below.
5. Record the pressure gauge reading or mark the needle position on
the face of the pressure gauge.
6. Operate the lter for a sufcient time to circulate the total pool water
volume daily. The lter should also be operated at all times the pool is
in use and for about one hour afterwards. During winter, the
running time may be reduced. Filter operating requirements will vary
for spa applications, depending upon the system design, type and
size of spa. Consult your builder or spa supplier.
7. When the pressure gauge reading is 50 - 70kPa higher than the
‘clean lter’ reading as in (4) above, it is time to clean the element/s.
(See “Cartridge cleaning procedure”)
Cartridge Cleaning Procedure
When the lter gauge reading is 50 - 70kPa above the clean lter gauge
reading, cleaning the element cartridge is required. To perform the cleaning
procedure :
1. Switch off the pump.
2. Close isolating valves on suction and discharge lines where tted.
3. Open the air bleed valve on the lter lid, unscrew the lock ring and
remove the lter lid.
4. Lift the element/s out.
5. In most cases the element can be easily cleaned with a garden hose,
using good velocity sprayed directly on the pleats.
NOTE:
Algae, calcium, clay, sun tan oil and body oils can form a coating on
the element which may not be easily removed with normal hosing.
These materials can be removed by soaking the element in a degreaser and/or de-scaler. Your local Davey Dealer will be able to
recommend suitable products.
Cartridge Re-Assembly Instructions
1. Install the cartridge/s & centre pipe so that it is located in the bottom
spigot.
2. Ensure the lter lid oring is clean, lubricated with oring lubricant and
located in the bottom groove of the lid.
3. Replace the lid and press rmly in place. Screw down the lock ring,
hand tight is sufcient - DO NOT OVERTIGHTEN.
4. Make sure the pump is primed according to manufacturer’s direc-
tions.
5. Ensure all valves are open on suction and discharge lines.
6. Start the pump.
7. Close the air bleed valve when water is expelled.
Water Quality
Maintaining balanced water chemistry is important to the life of your pool
pump. This pump is designed to be used with Pool & Spa water, balanced
in accordance with Langlier Saturation Index, with a pH level of between
7.2 and 7.8 and is regularly treated with a chlorine sanitising agent with the
level not exceeding 3000PPM.
Please consult your local pool shop regularly to have your water tested.
Filter Care
The Davey Cartridge Filter is the heart of the pool equipment installation.
Proper care and maintenance will add many years of service and enjoyment to your pool. Keep the exterior of the lter clean using a mild detergent and water.
Trouble Shooting
Reduced ow of water to the pool generally indicates the lter is ready to
be cleaned. Check the lter pressure gauge. (See section on ‘Filter Operation’). If cartridge cleaning is required, perform the steps described earlier in
‘Cartridge Cleaning Procedure’. If there is still reduced ow after cleaning,
check for blocked or plugged lines which could restrict the volume of water
entering the pool.
Dirt & debris returning to your pool may indicate the pressure relief
valve has been activated. Remove & clean the element and check
that valve inside base of lter is free of foreign matter.
Failure to undertake regular maintenance may cause damage not
covered by warranty.

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.
Specications
CLEARANCE TO REMOVE CARTRIDGE
NOTE: When making any enquiries about your Davey Filtration Equipment,
be certain to quote the Model Number from the nameplate on the equipment.
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 pres-
surised.
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 undi-
luted chemicals may damage pump and lter and void warranty.
