Instruction for use:
For use in static setting
The tank is suitable for water storage, distribution and chlorination and the cover help to prevent evaporation and contamination. The tank cannot be used for transportation.
The tank should be installed on an even, stable and horizontal earth platform at least 1.5 m above ground level or higher if possible. When the tank is installed on an earth embankment, the slopes of the embankment should be protected from erosion with dense grass, stones or plastic. The water distribution tap stand should be installed reasonably away from the tank with proper drainage arrangement to protect the embankment. The area surrounding the tank should preferably be fenced.
The tank shall be protected from direct sunshine as much as possible
The tank shall be thoroughly cleaned and dried before folding it for transportation or storage.
