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.
SAND FILTER MAINTENANCE
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.
1.
Switch off the sand filter and set the Control Valve to the
Closed function.
2.
Close the connection valves.
3.
Remove the Strainer Cover by unscrewing it.
4.
Take out the Strainer, remove any debris.
CLEANING THE STRAINER
5.
Put the Strainer back into position. Ensure
the hole in the strainer is aligned.
6.
Ensure the Seal Ring is in place. Secure
the Strainer Cover back.
7.
Open the connection valves.
NOTE:
The Strainer must be emptied and
cleaned periodically. A dirty or blocked
strainer will reduce the performance of the
sand filter.
