AWG | Fittings | Inductors Z2, Z4 and Z8
An adapter from the pump or from the hose on the inlet side is present.
9
The water hose for connection to the fixed coupling of the outlet side
9
is ready at hand.
The container with the required extinguishing foam or additive is ready
9
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 expansion
foam 5 – 6 bar) is present at the foam nozzle.

Foam nozzle flow rate
The connected consumer (foam nozzle or nozzle) must
achieve a water flow rate of at least 200 (Z2), 400 (Z4)
or 800 (Z8) litres per minute at 5 bar.
In the case of foam nozzles with significantly higher
through put, the throw distance or the admixing accuracy
may be affected, the inductor aspirating generally.
In the case of foam nozzles or nozzles with lower through-
put, no foam agent or additive is aspirated.
