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 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.
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. Other purpose flow rates may include but are not limited to: operating spa jets,
operating water falls or water features, operating a suction pool cleaner.
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 eCombi EE2 will provide around 29,000 litres per hour on high speed, depending on pipework, valves, filter size and other
equipment installed on your pool. On low speed the flow rate is approximately 14,000 litres per hour, therefore, operating
the pump 4 hours per day will provide a 56,000 litre pool one complete turn over.
Low speed will use approximately 20% of
the power consumption
that high speed will use.
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 HIGH medium speed to achieve full circulation and good surface skimming 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
time on high speed 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.
