1) INSTALLATION
We recommend you to locate the DOSABOX on a solid and flat ground, sheltered from the cold and
from direct light to prevent deterioration of the electrical and hydraulic components..
Fertilizer tanks must be placed at the same height of the pre-mixing tank..
The connecting pipes between the fertilizer tanks and injection group must be of the same length.
1.1 Connection to the main line
The DOSABOX must be connected to the irrigation network with a by-pass system (through a
derivation from the main line) using the two 1” threaded male. (See the installation diagram
attached)
It is recommended to assemble the included 1” filter on the inlet derivation of water to the venturi
injectors as per attached diagram.
!! NB: We recommend to install the DOSABOX after the main
filtering system.
