3.0 INSTALLATION
3.1 GENERAL
3.1.1 Position the filter as close to the swimming pool/spa as possible.
3.1.2 Position the filter so it is free from flooding, drainage infrastructure and areas where
water may pool, such as ditches, guttering, garden hollows, etc.
3.1.3 Position the filter so that the piping connections, Multiport Valve and winter drain is
convenient and accessible for operation, servicing and winterising.
3.1.4 Ensure that the compliance label is facing the front to allow easy identification.
3.1.5 The filter should be placed on a level concrete slab, very firm ground, or equivalent.
Ensure that the ground will not subside, preventing any strain from the attached
plumbing.
3.1.6 Ensure that there is no movement of the filter during operation of the Multiport Valve.
3.1.7 Allow sufficient clearance around the filter to permit visual inspection of the entire
system.

3.2 FILLING THE FILTER MEDIA
3.2.1 Before filling the filter media into the filter vessel, carry out a visual check of the laterals.
Look for broken or loose laterals. Replace if necessary.
3.2.2 To eliminate stress on the laterals, fill the filter vessel half full of water to provide a
cushioning effect when the filter media is poured in.
3.2.3 (a) Top Mount Fibreglass Filters - Top Mount Fibreglass Filters are supplied with a
perforated plastic locator, which centres the stem and prevents media from entering
the stem pipe. Place the perforated plastic locator on the centre stem of the filter and
carefully pour in the filter media via the perforated holes of the plastic locator. Remove
the plastic locator once completed.
3.2.4 Note: If a template is not provided or is lost, you must centre the stem and cover the
stem opening to prevent non-alignment and media from entering the stem pipe.
3.2.5 (b) Side Mount Fibreglass Filters - Remove the top diffuser from the internal diffuser
pipe and place the flexible air relief tube inside the filtervessel and to the side, out of the
way. Cap the internal diffuser pipe with the filter media shield provided to prevent filter
media from entering it. Do not move the diffuser pipe, as this can affect the integrity of
the bulkhead seal.
3.2.6 Note: The above instructions do not apply to Side Mount Fibreglass Filters larger than
SM600 filters. Any filter media entering the diffusers will be removed during normal
operation.
3.2.7 Wash all the filter media and debris away from the threads and sealing surfaces of the
filter vessel.
3.2.8 Lubricate the o-ring or gasket on the Multiport Valve. The lubricant used should be
silicon-based and not petrochemical-based.
3.2.9 Thread the Multiport Valve or Top Cap onto the filter tank and hand tighten.
3.3 PLUMBING
3.3.1 Check that the incoming water pressure is within the filter’s recommended working
pressure. Ensure that a pressure limiting valve is installed if using mains water or a
high-pressure pump.
3.3.2 Ensure that a foot valve/non-return valve is installed if the pump is installed at 500mm
(20”) above the water level.
3.3.3 If the filter is installed below the water level or connected to mains water, isolation
valves should be installed at the inlet and outlet of the filter. This will prevent water
flow during any routine maintenance.
3.3.4 Minimise the length of pipe and the number of fittings to minimise restrictions to water
flow.
3.3.5 Connect all plumbing to the Multiport Valve, ensuring all plumbing connections are
glued and tightened securely to prevent leaking.
3.3.6 Ensure solvents/glues are not excessively applied to fittings as this could flow into
o-rings and create sealing problems.
3.3.7 Do not overtighten fittings or adapters.

3.4 MULTIPORT VALVE INSTALLATION
3.4.1 Top Mount Media Filters are supplied with either a top mounted screw down Multiport
Valve or a clamp down Multiport Valve.
3.4.2 Side Mount Media Filters are supplied with a side mounted Multiport Valve with a
plumbing kit designed to be connected to the side ports of the filter.
3.4.3 Each Multiport Valve is supplied with three threaded barrel unions.
3.4.4 Check that the top of the filter is free from any filter media or debris, and if there is a
valve o-ring, check that the valve o-ring is in place.
3.4.5 Check the label of each valve port and position the valve accordingly. The PUMP port
must be plumbed to the pump discharge, the WASTE port must be plumbed to the
waste line, and the RETURN port must be plumbed to the return line.
3.4.6 (a) Top Mount Screw Down Multiport Valve - Rotate the Multiport Valve into the filter
vessel’s threaded connection.
3.4.7 (b) Top Mount Clamp Down Multiport Valve – Align the valve with the top of the tank
flange. Place the coupling clamp half over the valve flange and the tank flange. Insert
the screws and nuts in the coupling clamp jaws, ensuring that the nuts are located in
the retainer slots on the clamp jaws. Tighten the clamp screws firmly and check that
the valve, tank flange and coupling clamp are correctly assembled.
3.4.8 (c) Side Mount Multiport Valve – Align the Multiport Valve’s plumbing kit with the
filter’s threaded connection ports. Screw the plumbing kit’s barrel unions onto the filter
connection ports, and hand tighten. Do not overtighten the barrel unions, as this can
lead to damage and void the product warranty.
3.4.9 Screw the Multiport Valve barrel unions onto the threaded connection ports of the
Multiport Valve and hand tighten. The barrel unions should be firmly threaded into the
Multiport Valve, and there should be no play between the thread. Do not overtighten the
barrel unions, as this can lead to damage and void the product warranty.
3.4.10 Glue the PVC pipe tothe barrelunions and allow the glueto set as perthe manufacturer’s
instructions before starting the filter.
3.4.11 Test the filter and check for leaks around the threads.

4.1 FILTER - POSITION FOR FILTRATION.
Incoming water from the piping system is automatically directed by the Multiport Valve
to the top of the filter bed. As the water is pumped through the filter bed, dirt and debris
are trapped by the filter bed. The filtered water is returned from the bottom of the filter
vessel through the Multiport Valve and back through the piping system.
4.2 BACKWASH - POSITION FOR CLEANING THE FILTER MEDIA.
Water flow is reversed by the Multiport Valve through the filter bed so that water flow
is directed to the bottom of the filter vessel and up through the filter bed, flushing the
previously trapped dirt and debris out of the waste line.
4.3 RINSE - POSITION FOR FLUSHING THE FILTER SYSTEM.
The water flow is directed by the Multiport Valve through the filter bed and out. This
process settles the filter media bed into place and ensures any dirt or debris is rinsed
out of the filter, preventing dirt or debris from returning to the swimming pool/spa.
Note: The RINSE position is not available on 4-Way Multiport Valves.
4.4 WASTE - POSITION FOR BYPASSING THE FILTER BED TO WASTE.
The water flow is directed by the Multiport Valve straight to the backwash outlet,
bypassing the entire filter bed. This Multiport Valve position is used to lower the water
level or to vacuum water with high dirt loads.
4.5 RE-CIRCULATE - POSITION FOR BYPASSING THE FILTER BED TO THE POOL/SPA.
The Multiport valve recirculates water flow directly back to the swimming pool/spa,
bypassing the filter.
4.6 CLOSED – POSITION FOR CLOSING ALL FLOW TO THE FILTER.
The Multiport Valve can be closed to enable pump servicing without draining the
water from the filter. This position is not to be used with the pump operating.
Note: The CLOSED position is not available on 4-Way Multiport Valves.
4.7 iCAUTION: Operation of the Multiport Valve or mode selection is always to be done
with the pump switched off.

5.0 INITIAL STARTUP OF FILTER
5.1 Be sure the correct amount of filter media is in the filter vessel and that all connections
are hand tightened.
5.2 Depress Multiport Valve handle, rotate to the BACKWASH position, and open the air
release valve on the filter or Multiport Valve.
5.3 Note: To prevent damage to control valve seal, always depress handle before turning.
5.4 Switch on the pump and open the Inlet Valve allowing the filter vessel to fill with water.
5.5 Note: If a pump is installed, switch the pump on and off, instead of closing and opening
the Inlet Valve.
5.6 Once a steady flow of water runs through the waste line, close the air release valve and
let the pump run until the wastewater is clear. The initial backwashing of the filter is
recommended to remove any impurities or fine particles from the filter media until the
sight glass is clear. This process may take up to 3 minutes.
5.7 Turn the pump off, rotate to the RINSE position, switch on the pump and open the Inlet
Valve until the water in the sight glass is clear — approximately 10 to 15 seconds.
5.8 Switch off the pump and close the Inlet Valve, set the Multiport Valve to the FILTER
position, switch on the pump, and open the Inlet Valve. The filter is now operating in its
normal filter mode.
5.9 Adjust pool suction and return valves to achieve the desired flow. Check the plumbing
and filter for water leaks and tighten connections, bolts, and nuts, as required.
5.10 Record the pressure gauge reading (start up pressure) during the initial operation. After
a period of use, the accumulated dirt and debris in the filter causes a resistance to flow.
The pressure will start to rise, and the water flow will decrease. When the pressure
gauge reading is 50kPa (7.2psi) higher than the initial start up pressure, it is time to
backwash and clean the filter, see 6.0 Backwashing.
5.11 Note: If the filter is connected to mains water, it is not necessary to record the start up
pressure, as mains pressure tends to fluctuate.
6.0 BACKWASHING
6.1 GENERAL
6.1.1 The function of backwashing is to separate the deposited particles from the filter media
and flush them from the filter bed. Backwashing is achieved by reversing the flow of
water through the filter bed at a fairly high flow rate. This high flow rate expands the
filter bed and the water flow carries the debris out to waste.
6.2 IMPORTANCE OF BACKWASHING
6.2.1 The importance of backwashing cannot be overstated. Without proper and frequent
backwashing, filter media can become ‘packed’ — creating channelling in the filter bed,
loss of efficiency and early exhaustion ofthe filter bed. Moreover, if debris is not flushed
from the media, the filter bed will saturate until the filter fails to operate.

7
6.3 CONDITIONS FOR BACKWASHING
6.3.1 The requirements for backwashing are determined by the following conditions:
1. The flow rate through the filter bed decreases until it is insufficient to meet the
demand.
2. The debris removal efficiency of the filter bed decreases to the point where filtered
water quality deteriorates or results in dirt or debris returning to the pool.
3. The pressure gauge reading is 50kPa (7.2 psi) higher than the start up pressure.
Note: If the filter is connected to mains water, pressure rise is not an accurate
indicator as mains pressure tends to fluctuate. It is best to rely on the actual flow rate.
6.4 BACKWASHING INSTRUCTIONS
6.4.1 Switch off the pump and close the Inlet Valve.
6.4.2 Release the filter’s pressure by loosening the Pressure Release Valve until the pressure
gauge needle drops to zero.
6.4.3 Retighten Pressure Release Valve.
6.4.4 Depress and turn the handle 180° to the BACKWASH position. In the BACKWASH
position, water flow is automatically reversed through the filter so that it is directed
to the bottom of the filter vessel and up through the filter bed, flushing the previously
trapped dirt and debris out the waste line, see Fig. 3.
6.4.5 Switch on the pump and open the Inlet Valve. Backwash water will flow out through the
filter bed drain pipe.
6.4.6 When the backwash water in the sight glass appears clear, switch off the pump and
close the Inlet Valve.
6.4.7 Depress and turn the handle to the RINSE position. In the RINSE position, water flow is
directed through the filter bed as normal filter mode but out through the waste outlet.
This process settles the filter media bed into place and ensures any dirt or debris is
rinsed out of the filter, preventing possible return to the pool.
6.4.8 Switch on the pump and open the Inlet Valve. Rinse water will flow out through the
drain pipe.
6.4.9 When the rinse water in the sight glass appears clear, switch off the pump and close
the Inlet Valve.
6.4.10 Depress and turn the handle to the FILTER position and switch on the pump and open
the Inlet Valve for normal operation.

7.0 MAINTENANCE
7.1 The filter media will only require replacement once it has reached the limits of its
designated life. Refer to the product information of the particular filter media used.
7.2 To ensure the maximum life of the selected filter media, please follow the procedures
below:
1. Backwash the filter regularly as per 6.0 Backwashing.
2. Refer to the specifications of the filter media used and implement regeneration
procedures accordingly.
3. 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: 7.2 - 7.8.
Total Alkalinity: 80 - 150ppm.
Calcium Hardness: 150 - 300ppm.
And 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.
7.2.1 To prevent damage to the pump and filter and for proper operation of the system, clean
the pump strainer and skimmer baskets regularly.
7.2.2 Replace the pressure gauge if faulty readings are observed.

8.0 TROUBLESHOOTING
Fault/Problem Possible Causes and Remedies
Above normal or
excessive force
to operate the
Multiport Valve
Scoring or jamming with foreign matter or debris. If this condition persists after
rinsing, disassemble the valve to clear dirt and debris. Continued operation of the
valve may result in a non-sealing condition (damage to spider gasket). This will lead
to water loss to the backwash line or to inecient ltration.
Note: A lter sock is recommended during pool vacuuming, to prevent dirt and
debris lodging between the spider gasket and Multiport Valve body.
Water is not clear
Insucient ltration time.
Heavy bathing or dirt load.
