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 0.45 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: Pressure gauge is for maintenance purpose only,
and the pressure gauge value is just for reference, it should
not be used as a precision instrument.
NOTE: 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.
