External Pump Filling (Hydrants) Connection

causym CAUTION: If the tank is filled via a high capacity hydrant it is recommended to open the tank lid in order to avoid "blowing up" the tank. The maximum filling capacity for the external pump filling system is 500 l/min and the maximum pressure allowed is 4 bar. Never exceed this filling capacity and maximum pressure.

For safe and easy filling of the machine via an external pump (hydrant), a special hydrants connection is available to prevent backflow of spraying liquid to the hydrant. A hose (50 mm) can be connected to the left front of the machine (A). There are different couplings available like camlock (quick release coupling), Fire Service and C-coupling (Storz). These couplings are delivered separately (male and female parts with hose barb and hose clamps). The male coupling should be screwed into the 1.5" thread connection (A) on the left front side of the sprayer and the female coupling with hose barb should be connected to the supply hose with the hose clamps.

The liquid then flows via a 1.5" ball valve (B) to the hydrant connection (E) located above the raised filling hole. This has four recesses at the end. During the filling process, the water is sprayed with great force into the tank. In the case of a malfunction (for example a loose hose), air will flow through the four recesses, so that spraying liquid cannot flow back. After the filling process, the overflow piece with hose is fitted near the filling hole on a camlock (C). The cover cap (D) with chain must be used to close off the connection.

Before the supply hose is uncoupled, the 1.5" ball valve must be closed in order to prevent any leftover liquid in the hose flowing back.
