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. However, it
is essential that your professional pool installer adjust
your low speed so that your chlorinator cell remains
full or near full of water during operation and that your
skimmer weir door is creating sufficient surface tension
to skim leaves from your pool. Other factors for
adjusting low speed may include satisfactory operation
of a suction cleaner or increased flow rate to circulate
water to “dead” spots in the swimming pool.
• Medium Speed
is generally set up as your special
purpose flow rate. For example, an In floor cleaning
system will require higher pressures and flow rates
to operate and medium speed can be set up to
operate the In floor 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.
• Overdrive Mode
can be used to drive in floor cleaning
systems, obtain extra pressure when spa jets are
selected or for additional vacuum suction when
cleaning the pool.
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 P320XT 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 P520XT 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 hour. 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.
