Dual stage 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 nally polished via its inbuilt cartridge lter, producing
crystal clear water.
Simple maintenance
MultiCyclone Plus’s sediment chamber is easily cleaned
by opening its purge valve. Only 15 litres of water is
discharged.

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.
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. Ensure solvents are not excessively applied to ttings as this could run into “o”-rings and
create sealing problems.
7. Do not over tighten ttings or adapters.
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 Plus 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. Connect the pipe extending from the pump outlet to the inlet of the MultiCyclone Plus.
2. Connect from the pipe extending from the outlet of the MultiCyclone Plus to the next
component in line with the ltration system or water return line.
3. Glue all plumbing to barrel union ttings in accordance with glue (solvent) manufactures
specications and allow 24 hours to set. Ensure glue (solvent) is not excessively applied to
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 Plus on
the pool return line to assist with ushing out the collected debris. Please refer to “Insufcient
Water Pressure”.
4. Turn on pool pump. Be sure to check that there are no leaks from the connectors. If required,
tighten by hand.
START UP PROCEEDURES
The MultiCyclone Plus is an advanced and highly efcient lter system that will provide years of
trouble free service if the following maintenance procedures are maintained.
To start up the ltration system either from new or after cleaning is exactly the same.
1. Ensure that the MultiCyclone Plus is plumbed correctly.
2. Ensure that all valves installed before and after the MultiCyclone Plus are open.
3. Loosen the air release valve on top of the MultiCyclone Plus lter lid.
4. Prime the swimming pool pump. (Refer to the pump installation and operation manual).
5. Turn on the swimming pool pump and allow the pump to run until all the air has been expelled
from the MultiCyclone Plus. Water will run from the air release valve.
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 lid of the MulitCyclone Plus whilst adjusting the air release valve
to purge the system of air.
Injury may occur if air release valve becomes loose.

MULTICYCLONE PLUS 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 Plus’s clear sediment chamber. The MultiCyclone
Plus is cleaned by simply opening the purge valve. Only 15 litres (4 gallons) of water is
discharged to clean the MultiCyclone of sediment.
2. A pressure gauge reading of 50kPa (7.2psi) above the operating pressure may result in a
reduced ow rate that is insufcient to meet the requirements of the pool.
Example: Filter operates normally at 60kPa (8.2psi) needs to be cleaned at 110kPa (16psi).
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 Plus 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.
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
Plus on the pool water return line.
The 2 way valve is used to throttle the ow of water out of the MultiCyclone Plus, 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 sedimement chamber is clean, open the 2 way valve and then close the purge valve.
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.

FILTER CARTRIDGE MAINTENANCE
To ensure maximum life from your MultiCyclone Plus’s lter cartridge you need to maintain the
lter cartridge regularly.
When the lter is rst started and has been purged of air, note the pressure on the pressure
gauge. This is what is known as the lter operating pressure and it is important that you be
aware of this gure.
All ltration systems will operate at different pressures depending on the pool hydraulics.
You will need to clean the lter cartridge once the pressure gauge has reached 50kPa (7.2psi)
above the operating pressure.
Example: Filter operates normally at 60kPa (8.2psi) needs to be cleaned at
110kPa (16psi).
Cartridge Cleaning
Prior to removing the MultiCyclone Plus cartridge lter’s lid, you will need to release the pressure
from the lter cartridge housing. With the pump off, loosen the air release valve on top of the
MultiCyclone Plus lter lid to release pressure from the lter housing.
1. Undo and remove the clamp around the cartridge lter’s lid by unscrewing the tightening
nuts, this can be either by hand or using a 25mm (1”) open end spanner/adjustable wrench
on the moulded hexagon section and remove the lid off the lter tank.
2. Remove the lter cartridge from the lter housing.
3. Using a garden type hose clean the surface of the pleated element. Make sure to clean
between the pleats.
4. Place the lter cartridge back into the lter housing ensuring that it is seated correctly.
5. Ensure the lid “o”-ring is clean of any debris and is correctly seated into lter body “o”-ring
groove prior to lid being retted.
6. Place the lid onto the lter housing and ret retaining clamp band and tightening nuts using
a 25mm (1”) open end spanner/adjustable wrench ensuring lid is correctly tted.
7. Refer to the start up procedure to recommence operation.

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
Plus on the pool water return line.
The 2 way valve is used to throttle the ow of water out of the MultiCyclone Plus, 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 sedimement chamber is clean, open the 2 way valve and then close the purge valve.
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.

FILTER CARTRIDGE MAINTENANCE
To ensure maximum life from your MultiCyclone Plus’s lter cartridge you need to maintain the
lter cartridge regularly.
When the lter is rst started and has been purged of air, note the pressure on the pressure
gauge. This is what is known as the lter operating pressure and it is important that you be
aware of this gure.
All ltration systems will operate at different pressures depending on the pool hydraulics.
You will need to clean the lter cartridge once the pressure gauge has reached 50kPa (7.2psi)
above the operating pressure.
Example: Filter operates normally at 60kPa (8.2psi) needs to be cleaned at
110kPa (16psi).
Cartridge Cleaning
Prior to removing the MultiCyclone Plus cartridge lter’s lid, you will need to release the pressure
from the lter cartridge housing. With the pump off, loosen the air release valve on top of the
MultiCyclone Plus lter lid to release pressure from the lter housing.
1. Undo and remove the clamp around the cartridge lter’s lid by unscrewing the tightening
nuts, this can be either by hand or using a 25mm (1”) open end spanner/adjustable wrench
on the moulded hexagon section and remove the lid off the lter tank.
2. Remove the lter cartridge from the lter housing.
3. Using a garden type hose clean the surface of the pleated element. Make sure to clean
between the pleats.
4. Place the lter cartridge back into the lter housing ensuring that it is seated correctly.
5. Ensure the lid “o”-ring is clean of any debris and is correctly seated into lter body “o”-ring
groove prior to lid being retted.
6. Place the lid onto the lter housing and ret retaining clamp band and tightening nuts using
a 25mm (1”) open end spanner/adjustable wrench ensuring lid is correctly tted.
7. Refer to the start up procedure to recommence operation.

Do not over tighten the lid tightening nuts.

I pg 10
It is suggested that you should periodically remove the lter cartridge and soak it over night in
a suitable cartridge cleaning compound. This will remove any debris not removed by hosing
down of the lter cartridge.
Some swimming pool stores offer a lter cartridge cleaning service using the correct solutions
otherwise you may wish to use Waterco Cartridge cleaning solution. Directions of use are on
the product.
The cleaning time depends upon the swimming pool condition and use. Intervals between
cleaning the element should not exceed a period of 12 months in any instance.
GENERAL MAINTENANCE GUIDE
To ensure the maximum life of the MultiCyclone Plus, please follow the procedures below:
1. Clean the lter cartridge regularly according to the instructions set under “MultiCyclone Filter
Cartridge”
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.
WINTERISING
Proper winterising procedures should always be taken in order to protect your lter in cold
climates (temperatures below freezing point).
1. Switch off the Pump / Close the inlet valve.
