The water hose for connection to the fixed coupling of the foam nozzle
9
is ready at hand.
If the device is equipped with a stop valve with hand lever, the hand
9
lever must be closed (Fig. 2/B).
Coupling the hose
1. By hand or with the use of a coupling spanner, attach the coupling of
the water hose (Fig. 2/6) to the coupling on the foam nozzle (Fig. 2/5).

2. Point the finishing tube (Fig. 2/1) at the source of fire.
3. Open the water supply.
The water supply is started. Once a steady water pressure has built up, a uni-
form extinguishing foam is produced. The extinguishing foam is produced as
long as the foam agent is admixed and the hand lever remains open.
The pressure gauge indicates the inlet water pressure.
4. Interrupt the water supply.

2. Open the water supply.
3. Point the finishing tube (Fig. 2/1) at the source of fire.
4. Open the foam nozzle by turning the hand lever (Fig. 2/4) longitudinal
to the direction of flow of the water (Fig. 2/A).
The water supply is started. Once a steady water pressure has built
up, a uniform extinguishing foam is produced. The extinguishing foam
is produced as long as the foam agent is admixed and the hand lever
remains open.
The pressure gauge indicates the inlet water pressure.
5. Close the hand lever (Fig. 2/4) crossways to the flow direction of the
water (Fig. 2/B).

Required flow pressure
The foam nozzle is designed for a flow pressure of 3 to
5 bar on the inlet side. Within this range, optimum foaming
is achieved.
