SELECTION OF APPROPRIATE SPEEDS
General Rules:
The total volume of water in your pool should be turned over at least once a day.
If operating for longer periods of time, you may be able to turn the output of your salt chlorinator to a lower
level. Check your chlorine level frequently to ensure you do not over or under chlorinate your swimming
pool.
Low Speed
is factory pre set and is the recommended setting for your daily filtration flow rate
–
enough to
gentle turn the water over once per day and circulate the water completely around your pool.
Medium Speed
is generally set up as your special purpose flow rate. For example, an infloor cleaning
system will require higher pressures and flow rates to operate and medium speed can be set up to operate
the infloor cleaning system. Other special purpose flow rates may include but are not limited to:
operating spa jets, operating water falls or water features, operating a suction pool cleaner.
High Speed
is generally set up to backwash your sand filter. As a rule of thumb, this speed should be set
so that the gauge on your filter is approximately 70kPa to 100 kPa in pressure but this will depend on the
size of your filter, and the size and length of the backwash pipe line.
In warmer weather, or when the pool is used a lot, your pump should operate for 12 hours a day or more. Check
your chlorine levels and visually inspect your water to ensure that (a) you have adequate chlorine and (b) the water
in your pool looks clear and inviting. If you have any doubts, take a sample of water to your local pool shop for a
water analysis.

Some Tips:
The P320 will provide around 15,000 to 18,000 litres per hour on high speed, depending on pipework, valves, filter
size and other equipment installed on your pool. On low speed the factory preset flow rate is approximately 7,500
litres per hour
. Low speed will use approximately 10% of the power consumption
that high speed will use.
Therefore, operating the pump 8 hours per day will provide a 60,000 litre pool one complete turn over.
The P600 pump will provide around 36,000 litres per hour on high speed, depending on pipe work and the Factory
preset low speed at 1125 RPM will provide around 12,000 litres per minute. This is sufficient to turn a 96,000 litre
pool over once per day.
As a guide, low speed should achieve a visible skimming of the surface of the pool through your skimmer box.
When connected to an AstralPool compatible salt chlorinator, Viron Connect Touch Screen Control System, we
recommend that for one hour a day the filtration period is operated on at least medium speed to achieve full
circulation and good surface skimmer of the pool. The balance of the filtration cycle can then be set on low speed.
However, should your pool water develop cloudiness or your pool surface exhibit algae growth you may need to
increase the low speed of your pump to ensure adequate circulation of water and chlorine to all parts of your pool.
It is important to check your chlorine levels, pH and other parameters to ensure your water quality is correct before
adjusting the speed of your pump. We recommend these checks are carried out by your professional pool shop or
service technician.
