MULTICYCLONE
MultiCyclone is a brilliant preltration device that can save
water and minimise pool lter maintenance. Based on
the principals of centrifugal water ltration, MultiCyclone
lters up to 80% of the pool’s dirt load before it reaches
the pool lter and only requires 15 litres (4 gallons) of water
to cleanse.

Centrifugal Water Filtration
Incoming water tangentially enters its multiple hydrocyclones, generating a strong centrifugal
effect. Approximately 80% of the incoming dirt load is spiralled down to its clear sediment
chamber. The outgoing water is piped to the nally polished via the pools ltration system.
Simple maintenance
The MultiCyclone sediment chamber is easily cleaned by opening its purge valve. Only 15 litres
(4 gallons) of water is discharged.
Minimise Sand Filter Backwash Frequency
The installation of a MultiCyclone as a pre-lter to a sand lter can reduce its backwash
frequency to once per year, resulting in a saving of up to 7000 litres (1850 gallons) of water per
year for an average domestic sized swimming pool.
Minimise Filter Cartridge Cleaning and Replacement
The installation of a MultiCyclone as a pre-lter to a cartridge lter can reduce lter cartridge
cleaning and replacement to once per swimming season and even up to once per year,
depending on the size of the cartridge lter.

INSTALLATION
Be sure to comply with the local plumbing codes.
Be sure that all provisions for wastewater disposal meet local, state or national codes. Do not
discharge water where it will cause ooding or damage.
If the incoming water pressure is higher than the maximum operating pressure of 350kPa /
3.5Bar / 50psi, a Pressure Regulating Valve (PRV) must be installed upstream of the lter inlet.
ThePRVshouldbesetto90%ofthemaximumoperatingpressureofthetank.
If the incoming water ow is less than the lter’s minimum ow requirements, the lter’s ltration
efciency will be affected, please consult Waterco.
Typical Installation
1. Position the lter as close to the Swimming Pool / Spa as possible.
2. Position the lter so that it is free from ooding, away from sumps, guttering, garden hollows,
etc.
3. Position the lter so that the piping connections purge valve and air release valve is
convenient and accessible for operation, servicing and winterising.
4. Ensure that the compliance label is facing the front to allow easy identication.
5. The lter should be placed on a level concrete slab, very rm ground, or equivalent. Ensure
that the ground will not subside, preventing any strain from the attached plumbing.
6. Ensure that there is no movement of the lter during operation of the Purge valve.
7. Allow sufcient clearance around the lter to permit visual inspection of the entire system.

Optional Mounting Stand (200373)
An optional mounting stand is also available for situations where the MultiCyclone cannot be
installed directly above your pool pump.
Installation with optional Mounting Stand
Screw the supplied half barrel unions and tails onto the inlet and outlet before gluing the UPVC
piping onto the lter.
Use only recommended glue for connection pipe and fittings
Cut and t the pipe and ttings onto the MultiCyclone and the pump. Refer to Pump Installation
Manual for correct pump plumbing procedures.
It is best practice to t all the cut pipe and ttings onto the ltration system before gluing; this
will ensure that the system has been aligned correctly.
Glue the pipe and ttings onto the pump, lter and pool return lines and allow the glue to set
for 24 hours before commissioning the system.
Plumbing Connection
1. Ensure that a foot valve / non return valve is installed if the pump is installed 500mm / 20”
above the water level.
2. If the lter is installed below the water level or connected to mains water, isolation valves
should be installed at the inlet and outlet of the lter. This will prevent water ow during any
routine maintenance.
3. Minimise the length of pipe and the number of ttings to minimise restrictions to water ow.

ttings as this could run onto “o”-rings and create sealing problems.
Note: Waterco recommends that a shut off valve be installed after the MultiCyclone on the pool
return line to assist with ushing out the collected debris. Please refer to “Insufcient Water
Pressure”.
7. Connect to Waste Line. Glue the plumbing from the Sediment Purge Valve to a waste line,
drain or suitable drainage area.
8. Turn on pool pump. Be sure to check that there are no leaks from the connectors. If required,
tighten by hand.
!
Plumbing
1. Check that the incoming water pressure is within the lter’s recommended working pressure
and ensure that a pressure limiting valve is installed if using mains water or a high pressure
pump.
2. Ensure that a foot valve / non return valve are installed if the pump is installed 500mm / 20”
above the water level.
3. If the lter is installed below the water level or connected to mains water, isolation valves
should be installed at the inlet and outlet of the lter. This will prevent water ow during any
routine maintenance.
4. Minimise the length of pipe and the number of ttings to minimise restrictions to water ow.
5. Ensure that all plumbing connections are glued and tightened securely to prevent leaking.

6. Re-tighten the air release valve.
7. The lter is primed and ready for operation.
Note: In some cases this may be required to be done a few times before the unit will remain
primed and be fully operational.
Do not stand over the top of the MulitCyclone whilst adjusting the air release valve to
purge the system of air.
Injury may occur if air release valve becomes loose.
!
MULTICYCLONE FILTER MAINTENANCE
The MultiCyclone Plus lter maintenance is determined by the following conditions:
1. The sediment chamber is half lled with sediment. This accumulation of sediment can be
visibly monitored through the MultiCyclone clear sediment chamber. The MultiCyclone is
cleaned by simply opening the purge valve. Only 15 litres (4 gallons) of water is discharged
to clean the MultiCyclone of sediment.
Flush out the sediment chamber
With pump running:
Whilst the water pump is running simply open the sediment purge valve until the sediment has
been ushed out. This is visible through the clear sediment chamber. Once the sediment has
been ushed out, close the purge valve.
Without pump running:
Alternatively, switch the pump, off. Open the air release valve and then open the purge valve.
The water will drop through the MultiCyclone ushing out most of the debris from the sediment
chamber. Then close the air release valve and turn on the pump and the turbulence of the
water entering the sediment chamber will ush out the rest of the sediment. Once the sediment
chamber has been cleansed, close the purge valve, start the pump and close the air release
valve once water is owing out through the air release valve.

I pg 11
MultiCyclone
Do not close the 2 way valve prior to opening the purge valve and do not close the purge
valve while the 2 way valve is closed or partially closed. Both valves should never be
closed or partially closed at the same time.
If the MultiCyclone is installed as a pre-lter to a sand lter, water ow to the sand lter can be
closed via the sand lter’s multiport valve.*

*NOTE: This position is
not available on 4-Way
Multiport Valves.
INSUFFICIENT WATER PRESSURE
In situations where the water ow from the pump is not powerful enough purge the sediment
out of the sediment chamber. Waterco recommends tting a 2 way valve after the MultiCyclone
on the pool water return line.
The 2 way valve is used to throttle the ow of water out of the MultiCyclone, increasing water
turbulence through the sediment chamber and improving its purging action.
Whilst the pump is operating, open the purge valve, and then partially close the 2 way valve,
throttling the water ow sufciently to purge the sediment chamber of trapped sediment. Once
the sediment chamber is clean, open the 2 way valve and then close the purge valve.
!
GENERAL MAINTENANCE GUIDE
ToensurethemaximumlifeoftheMultiCyclone,pleasefollowtheproceduresbelow:
1. Visually monitor through the MultiCyclone clear sediment chamber. Clean sediment chamber
when accumulated sediment is half full.
2. Maintain a correct chemical balance of your pool / spa water. The chemical balance of water
is a relationship between its pH, total alkalinity, calcium hardness and water temperature.
The water must be maintained at all times to the following:
PHLEVEL  :BETWEEN7.2&7.8.
TOTALALKALINITY :BETWEEN80&150ppm.
CALCIUMHARDNESS :BETWEEN150&300ppm.
Also,withinthesetolerancesbebalancedtotheLangelierSaturationIndexwithinarangeof
-0.2 to +0.2.
Note: Testing kits are available to test the water yourself or alternately bring a sample of the
water to a professional pool and spa shop.
3. Mains water and rural water supplies need to be monitored. Saturation (life) in mains water
or bore (rural) will vary depending on water quality.
4. To prevent damage to the pump and lter and for proper operation of the system, clean
pump strainer and skimmer baskets regularly.
5. Replace the pressure gauge if faulty readings are observed.
