SAND FILTER MAINTENANCE
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 0.56 Bar (8.0 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.
CLEANING THE STRAINER
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.
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.
