20 " Big Blue cartridge with plastic housing is well suited for cleaning drinking and production water for apartments, private and summer houses with medium consumption (up to 10 m3 / month).
Another area of use is mechanical filtering of technological water, for example, before reverse osmosis device.
Depending on the purpose of use the BB-filters can be used alone as well as in series or in parallel connection.
Filters are connected with horizontal piping to a vertical position, preferably between valves. One can also add a by-pass valve and manometers for pressure control. Connecting with the water pipe with 3/4
" or 1 " internal thread.
The most important technical data is shown below:
Efficiency rates of up to 80 l / min.(4.8 m3 / h)
Housing dimensions (height x diameter) 610 x 185 mm
Allowed water pressure up to 8 bar
Allowed water temperature of 2-45 ° C
Suitable cartridge (length x diameter)20
x 4 1/2 "
INSTALLING THE FILTER
Installation of the filter must be carried out with the assumption that the rigid connection with the metal pipes don't leave mechanical strains to the screw connections, which can lead to cracks in the plastic housing.
Threaded bendy hoses with wire mesh suit well for connecting plastic filters. Filters are fastened to the wall by brackets in a vertical position. It has to have enough space from the floor, that you have room to unscrew the casing and change the cartridge element.
To simplify the element change, suitable valves are are installed in the input and output.
Filters can be connected in parallel to increase productivity. Filters can be connected in series for many different actions to take place at the same time (mechanical filtering - different possibilities for choosing a cartridge 5-20 micrometers, softening, enhancing the taste of water with activated carbon, for example through removing chlorine and organics, removing bivalent iron).
To monitor the loss of pressure(up to 0.5 bar) it's recommended to install manometers to know when to change the cartridge element in the right time.
For hygienic reasons it's recommended to change cartridge elements after every 6 months.
