INSTRUCTION AND MAINTENANCE MANUAL
2.2. INSTALLATION OF VALVE MANIFOLDS
Install the valve manifold before loading the lter with the lter aid. The valve
manifold brackets will support the weight of the valves, the pipes and the water
inside them, and will reduce the force that the lter connecons will need to
withstand. It is necessary to install these brackets on a suciently resistant surface
and adjust their height correctly.
2.3. HYDRAULIC TEST
Test the lters with water by running the system before lling them with lter aid.
This hydraulic test will detect any problems with water ghtness that may have
arisen with the lter or the set up.
2.4. FILLING THE FILTER
•Remove the upper cap of the lter and the side cover (if applicable).
•Check the condion of the internal parts before starng to load the lter aid into
the lter. The diuser and collector must be in perfect condion, and the nozzles
must be in their correct place and fully ghtened.
•Before loading the lter aid into the lter, ll it approximately halfway with water.
If it is a model with a side hole, ll it up to the level of the side hole. This will
prevent damage to the nozzles or collector arms while the lter is being loaded
with the lter aid.
•Use a lter aid that is recommended according to the technical informaon
supplied in the lter specicaons.
•The rst layer of gravel should cover the collector and reach to about 10cm
above it and be spread evenly across the whole surface. Care should be taken
when carrying out this procedure so as not to damage the collector.
•Load the following layers of sand following the same procedure,
unl the maximum recommended height is reached.
•Once the height of the side hole has been reached, replace the cap to
connue lling the lter.
•Carefully clean the neck of the lter, the cap and the cap seal, removing any
remaining traces of lter aid. Finally replace the seal and then replace and ghten
the cap.
•Once the lter is full and correctly closed, it must be cleaned.
