11. MAINTENANCE
A regular and thorough clean is necessary for the maintenance of your pool, in the long term this will save time, the equipment will last longer and
the water will be of a better quality.
For the correct maintenance of the filtration equipment (pump, valves, etc..) follow the manufacturers instructions.
Periodically inspect the filter media and all the filter components (diffusers, laterals, air and water drain cocks, pipes, seals etc..) including the
polyester tank, replacing or repairing any damaged parts.
Periodically clean the filter with pressurised water to remove dust accumulated over time. Do not use solvents that could damage the plastic parts
or the sight glass.
If you close the pool in winter adequately drain the equipment to prevent any damage from ice.
12. TABLE OF LOAD LOSS FROM VALVE BATTERY AND SAND FILTERS
The maximum operating temperature is 50ºC.
Under no circumstances should you exceed the maximum working pressure, indicated on the filter characteristics plate.
14. POSSIBLE FAULTS
PROBLEM
No filtered water flowing
You observe characters in the sand bed
Pressure gauge oscillates violently
Sand is entering the pool from the filter
Sand is escaping to the drain during backwash
Leaks in the connections or lids
CAUSE
The filter is dirty
The collecting basket is covered
Formation of preferential channels, lack of
backwash or broken collector
The pump has air in it
Suction half closed
There is something broken in the collector
system
Excessive water flow during backwash
Loose screws

13. SAFETY WARNINGS
Switch off the pump before operating any valve.
Do not connect the filter direct to the mains drinking water as
the pressure can rise and exceed the maximum authorised
working pressure for the filter.
Remember that it is very important to position the battery
valve supports to prevent any filter connections from
breaking.
The filters are designed to be highly resistant to internal
pressure, but at the same time they are very susceptible to
exterior knocks.
If the installation has more than one filter installed on the same
battery there should be a valve on each of the connections to
allow the filter to be completely isolated.
Start backwash
Clean the collecting basket
Start a backwash
Drain the sand and check if the collector is
defective. Replace the sand
Check the whole installation and eliminate
possible leaks
Check the suction valves are completely open
Repair the collector system
Reduce the flow rate during backwash
Tighten the screws, being careful not to break
any plastic pieces. If the problem is not resolved,
phone technical support
