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
