
An adapter from the pump or from the hose on the inlet side is pre-
sent.
 The water hose for connection to the fixed coupling of the outlet
side is ready at hand.

The container with the required extinguishing foam or additive is
ready at hand, and the pick tube is connected to the container.
Using the inductor
1. By hand or with the use of a coupling spanner, connect the adapter
of the pump-side hose (Fig. 2/1) to the fixed coupling on the inlet
side (Fig. 2/2).
2. By hand or with the use of a coupling spanner, connect the adapter
of the tube-side hose (Fig. 2/6) to the fixed coupling on the outlet
side (Fig. 2/5).
3. Adjust the setting sleeve (Fig. 2/4) to the required admixing rate.
4. Connect the pick tube to the inductor (Fig. 2/3) and insert it into the
foam mixing container.
5. Connect and close the required foam nozzle.
6. Carefully fill the hoses with water and pressurise.
7. Open the foam nozzle and regulate the pressure at the pump until
the required pressure (medium expansion foam 3 – 4 bar, low ex-
pansion foam 5 – 6 bar) is present at the foam nozzle.
Rinsing and uncoupling the inductor
1. Shut off the water supply.
2. Interrupt the supply of foam agent.
3. Open the water supply and the hand lever at the foam nozzle.
4. During rinsing, switch the setting sleeve through all settings in order
to ensure that all internal suction bores are cleaned.
