1. General
1.1. Swimming Pool Filters
Fig 1-1
Filters are, without a doubt, the most inportant accessory used in the treatment of swimming pool water. Their purpose is
to eleminate suspended particles from the circulating water, thuis improving the clarity of the water.
The principle of opeation consists of passing the swimming pool water through a bed of sand which will retain any
particles that are suspended in the water,
It should be kept in mind that the filtration system consists of a number of elements, such as metering equipment, pumps,
pool shell fittings and pipe work which ensures the correct suction and return flows that will affect the resultant condition of
the treated water.
Normally each country (possibly each state) will have its own standards for public and private pools. It is the responsibility
of the installer to be aware of these codes before designing, specifying or installing any piece of equipment for a
swimming pool.
The quality of filtration depends on various factors: the size and shape of the media, the media bed depth, characteristics
of the media such as granular size, density, etc. A most important paramenter is the water filtration rate. Other factors
affecting the selection of a filter are the materials used for its construction, the working temperature, and the operating
pressures.
1.2 Fluidra Filters
Manufactured from polyester resin and fiberglass, they are virtually corrosion-proof. The internal fittings (diffuser and
lateral system) are manufactured from PVC and ABS. They are unaffected by salt water and are normally manufactured
for a working pressure up to 50 psi and a maximum working temperature of 122°F.
Depending on the filtration velocity, filters are classified into three groups:
•SLOW RATE FILTERS: Filtration velocities 5 to 10 GPM/ Ft² of filtration area
•MEDIUM RATE FILTERS: Filtration velocities from 10 to 15 GPM/ Ft² of filtration area
•HIGH RATE FILTERS: Filtration velocities in excess of 15 GPM/ Ft² of filtration area
For good filtration results, we recommend that filtration velocities of 15 GPM/ Ft² are not exceeded, bearing in mind that
filtration velocity is dependent on the granular size of the media and the bed depth. It is also important to check all state
and local codes that pertain to water filtration for swimming pools.

1.3 Selection of filters and installation
1.3.1Filter charateristics
Fluidra recommends that the filtration system should filter at least 50% of the water from the surface of the pool as well as
50% from the lower levels of suction. The maximum turnover time for a publice pool should not exceed 4 hours, and for
semi-public pools 6 hours. In case of publice pools for children the turnover should not exceed 1 hour. The times will vary
from state to state and all local and state codes must be satisfied when using any filtration system.
Example:
If we have a public pool with a capacity of 15,000 gallons we need a filter capable of filtering this water in 4 hours:
15,000 gal/ 4 hours = 3,750 gal/ hour or 62.5 GPM
To obtain a high quality water filtration we recommend that the filtration velocity should comply with the following:
Water parks 10 GPM/ Ft² Commercial Pools 15 GPM/ Ft²
62.5 GPM/ 10 GPM/ Ft² = 6.25 Ft² of filtration area required
Now choose the filter or filters that meet this requirement. Remember it is possible to add filters together to obtain the
correct amount of filtration area required. It is also a good idea to oversize the surface area required by 10% or more, this
will allow better water quality. Whenever possible use more than one filter in conjunction, this will allow one filter to be
serviced while one is still functioning.
When sizing the plumbing for a filtration package be sure to keep in mind that the velocity of the water pipes is very
important. Each state or country may have different maximums for velocity in the plumbint. The recommendations of
Fluidra are as follows: the return line should not exceed 10 ft./ s and the suction line should not exceed 5 ft./ s.
1.3.2 Installation characteristics
To insure the correct pump size, the required flow must be obtained by taking the system head into consideration. The
system head is the added difficulty to move the water through the system presented by using elbows, piping, tees,
changes in elevation, etc. Normally, 60 ft. of water (60’ of head) is sufficient but will depend upon each individual system.
It is advisable to use the same number of pumps as filters, each pump producing the required flow for one filter. It is also
recommended that the discharge from each pump is brought together in a single manifold to the filters. This will allow
greater rates for the backwash cycle.
For each suction side, it is also recommended that the supply to each pump come from either a general suction manifold
or balance tank. The should be taken from both the surface and from the bottom of the pool.

3. Installation
3.1 General installation notes
BEFORE DOING ANY INSTALLATON IT IS VERY IMPORTANT TO READ THIS ENTIRE SECTION.
Note: Filters are supplied in a box with accessories included. Due to their weight and size it is recommended that
mechanical means be employed to move the filters into position. It is also very important to inspect the filters carefully
before installing. Make noe on the shipping paperwork if there is any damage to the packaging. Polyester filters can
be damaged easily during transportation and is the responsibility of the installer to inspect at the time of delivery.
Damages to filters from transportation that are not noted on the bill of lading are not covered by Fluidra’s warranty policy
and all costs to repair will be the responsibility of the owner.
Never put the media into the filter until it is in its final working position and all prior steps are complete.
The filters should be accessible for periodic maintenance or media change. It is absolutely necessary to leave a minimum
access space around the filter(s).
It is recommended that the filters be installed below the level of the pool surface and as near as possible to the balance
tank or pool itself.

The equipment room should be well ventilated and provided with adequate drainage capabilities so that should an
emergency occur, resulting in flooding from a pipoe, filter or pump, the water can be easily
damage. If drainage cannot be supplied directly from the equipment room, consideration should be given to the
installation of an alternate system to remove water from the mechanical room.
3.2 Filter Installation
Move the filter(s) in
to place using whatever means available. Be sure to use care if moving by hand. Be careful not to hit
the filter against something solid while positioning. Before continuing, be sure that the filter(s) are in the desired locati
with the connection facing
the direction necessary for proper installation. It is also very important to make sure the filter is
sitting on a level hard surface.
It is possible that during transportation, some of the internal components have loosened. It is now necessary to remove
the filter lid and enter the filter, being careful not to break any of the connections. By hand, check the tightness
laterals in the bottom of the filter making sure they are firmly tightened. Also, while in the filter, check for any cracks o
breaks in the body of the filter or the PVC internals that might have occurred during transportation using a flashlight.
Refer to the parts breakdown section at the back of the manual for quantity and location of all accessories for reference
during the installation process.

to see some types of damage that may have occurred. It is important to test the system without sand first to check for
leaks. Fill the system with water, replace the lid and gasket. Run the system as normal and check for leaks. If there is a
problem with the test, contact Fluidra customer service immediately. If sand is added before the test and there is a
problem with the filter, the sand will need to be evacuated for inspection. Fluidra will not pay for the removal and
replacement of the sand under warranty, nor will Fluidra provide the labor to evacuate and replace the sand for repair
work done due to transportation or installation damage. This also a good chance to check all plumbing for the system. Do
not drain the water from the fitler after the testing sequence.
3.5 Installation of the media
After the testing has been finished and the system is 100% operation, we need to add the filteration media required.
Remove the lid and gasket from the fitler as before. The filter should be full of water at this time. If the filter is not full of
water, the filter needs to be filled at least to the diffusers before adding the media. The proper amount of media for each
filter is listed in Fig. 2-1. If a diffuser head is directly underneath the manhole cover, remove diffuser assembly or cover
with plastic and tape to prevent media for entering the plumbing.
Now, replace the lid and gasket to the top of the filter. Be sure the cover is free of sand. If the cover is not free of sand, the
gasket will not seat properly and could cause the filter to leak at the lid. Put the filter into backwash mode (see next
section) and run for about 5 to 6 minutes. This will level the sand inside the fitler. Put the valves into the filter position and
the system is ready for operation.
4. Operation
4.1 Filtration
Note: There are many different styles of manifolds and multiport valves available for the Aster line of filters. !!!NOTE,
Tank must be full of water prior to start of the Filtration Mode!!!
With the pump off, arrange the valves or multiport into the filtration position. Normally, while a filter is running, inlet
pressure is 12 to 15 psi and the outlet pressure is 6 to 9 psi. This is normal pressure when the filter is clean. As the filter
media cleans the water, it traps particles of debris from the water inside the filter. These particles will make it more
diffucult for water to pass through resulting in less water flow and a higher filter pressure. When the pressure rise is 7 psi
above starting pressure, it is time to backwash the system.
4.2 Backwash
In filter beds, there are thousands of channels for water to pass through, trapping particulate matter. As time passes these
channels become blocked and it becomes necessary to clean the filter bed to restore the filter to its optimum working
condition by discharging the trapped particles to drain. The velocity of the water for the backwash cycle should be the
same as for the filtration mode. This velocity should never exceed 20 GPM/ Ft² of filtration surface area to prevent
discharging sand to drain and possibly damaging the filter.
The backwash cycle should run for 3 to 5 minutes. It is advisable to fit a sight glass in the drain line close to the filter so
that when backwashing is carried out, one can see the water clearing and stop the backwash when the water is clean to
avoid an unnecessary waste of water.
To carry out the backwash, stop the pump, set the valves into the backwash position and restart the pump. Once
backwash is complete turn off pump and position valves to retain water inside the filter vessel. Reposition the valves to
the filter mode and start the pump immediately. If water is allowed to escape the fitler vessel, the sand bed will be
disturbed by the introduction of air. !!!Note, the filter tank must be full of water after backwash and before starting
the filtration mode!!!
4.3 Empty
When it is necessary to empty the pool, it is possible to drain through the filter system. The water can be redirected to
waste using the multiport valve on the filter. The valve can be positioned in the drain position and the filter will by-pass the

filter and go directly to waste. !!!Note, before moving the position of the multiport valve always discontinue
operation of the pump!!!
4.4 Isolate/ Close
As the name implies, the multiport valve can be put in the closed position. This position is used for filter maintenance,
cleaning and general shut down of the facility. !!!Note, before moving the position of the multiport valve always
discontinue operation of the pump!!!
5. Changing of the filter media
The procedure for changing the filter media is as follows:
• Turn offf pumps
• Remove lid and gasket from filter
• Open the water drain port to drain the water from the filter
• Using a shop vacuum or small bucket remove the sand
• Using a hose from above, spray the sand to loosen if necessary
• Clean the remaining sand from the walls as best as possible with the hose and vacuum
• Add the filtration media as required in Figure 2-1 of this manual
6. Other recommendations of Interest
• Fluidra filters are virtually corrosion resistant and need very little maintenance. It is advisable to clean the surface
of the filter every 2 years, or whenever dirty, with a mild soap and water to maintain the looks of the fitler
• Every filter is equipped with a manual air vent fitted in the top of the filter. In addition, each filter has a water drain
located in the bottom of the filter that can be connected directly to a drain.
• When installing the valve manifold system, it is advisable to use adequate pipe supports to suppor the weight of
the manifold and the water flowing through it. Supports can be purchased from Fluidra if not already included with
the fitler manifold box.
• If the installation is to be shut down for long periods of time, it is advisable to drain the water during the period of
non-use.
• Where freesing can occur, be certain to drain the filter before the opportunity to freeze can occur. Freezing of the
water in a full filter will result in permanent damage to the fiberglass shell.
