1.
Now the sand filter is ready for use. Set
the Control Valve to the Filter function.
NOTE:
To prevent the risk of electrical
shock dry any excess water from yourself
and the sand filter.
2.
Switch on the sand filter to run it.
NOTE:
The sand filter has now started its
filtering cycle. Check that water is returning to the pool and
take note of the filter pressure on Pressure Gauge. Generally,
the recommended sand filter pressure is less than
0.45 Bar (6.5 PSI) when it is running.
CAUTION:
You must ensure the sand
filter is switched off and unplugged
before any maintenance begins or
severe risk of injury or death exists.
As dirt builds up in the sand filter, the
pressure reading on Pressure Gauge
will increase. When the Pressure
Gauge is 0.45 Bar (6.5 PSI) or higher,
or water flow to the pool is too low, it is time to clean the
sand.
To clean the sand bed, follow all instructions outlined
previously in
: Backwash and Rinsing.
NOTE:
1.
The Pressure Gauge is just used for measuring the water
pressure, not used for precision measurement.
2.
We recommend you clean the sand bed once a month or
less regularly depending on how often the pool is used. Do
not clean the sand too frequently.
