Astralpool CANTABRIC 400 Manual De Instalación Y Mantenimiento página 4

INSTALLATION
The filter should be installed as close as possible to the swimming pool and preferably at a level of 0,50 metres below the
surface of the water in the swimming pool. Make sure there is drainage available at the place where the filter is to be
installed.
If the filter is installed indoors, a correctly sized drain should be installed, to drain off as much water as possible from the
swimming pool, to avoid flooding risks of the premises or adjoining areas. If this is not done, the filter manufacturer will
not be held liable for possible damage to third parties caused by the filter.
IMPORTANT: Do not use an iron and hemp pipe for the selector valve connection, it is essential to use plastic accessories
and TEFLON tape. Pipe terminals are available threaded fixing in 1 ½ " and 2".
Always leave enough space round the filter in order to perform the necessary examinations and maintenance during the
filter's life.
ASSEMBLY
Follow these indications for a correct assembly of the filter:
1.- Place the filter on a horizontal and clean surface.
2.- Place the filter in its final location.
3.- In case of a filter with a lateral valve, install the selector valve in the filter. Make sure that the joints between the valve
and the filter are correctly placed.
4.- Perform the three connections of the selector valve: pump piping to the valve, valve to the waste drain and valve to the
pool return. Each of these three outlets is clearly identified on the valve.
5.- Set the manometer T, the joint, the manometer and the air drainage (see exploded view). It is not necessary to use
teflon tape, as the watertightness is guaranteed in this case by the joint. Do not tighten the manometer T with a tool, as
manually will be sufficient.

16 / 32 inches. With the quantity indicated on the plate specifying the characteristics; proceed as follows:
Load up when the filter is installed in position and the connection pipes have been joined.
1.- Unscrew and remove the cover.
2.- Remove the selector valve or transparent cover, depending on the model, and the O-ring.
3.- Check that all collector arms are in good condition.
4.- Fill the filter with water to half capacity.
5.- Pour the required, slowly and very carefully, quantity of sand, as indicated on the label, inside the filter.
6.- Clean the seating of the lid joint.
7.- Place the O-ring and the selector valve or transparent cover, depending on the model.
8.- Screw on the cover.
Attention: when operating check that water does not leak from the filter through the cover.
Note: the manufacturer will not be held responsible for any damage caused to the filter while filling it with sand.
