Description The FFS Foam inductor Adjustable is designed as a simple and reliable construction and offers a unique combination of high performance in relation to weight and dimensions.

The Foam inductor is for installation in the piping system between the water pump and the monitor(s). A typical installation is in a by-pass line around the discharge valve to save pressure loss when Foam inductor is not in operation. The Foam inductor is of wafer type and is installed between two flanges. Suction height of foam liquid must be considered.

The Foam inductor generate vacuum and inject foam into the water line according to specified mixing ratio. It is equipped with a check valve to prevent water from accidentally entering the foam tank and a metering valve for foam mixture setting.

Each Foam inductor is order specific for each system and FFS ensure the correct performance according to pressure and water flow calculation.

Material for the Foam inductor is bronze alloy with excellent corrosion resistance and diffuser is composite.

Due to the simple construction the FFS foam Foam inductor is reliable and require no maintenance.

1 GENERAL DESCRIPTION

This document is made to describe the operation and maintenance of the foam mixing inductor FFS 300Fi to FFS 600Fi designed and manufactured by FFS AS.

The FFS Foam inductors offer a unique combination of high performance in relation to weight and dimensions.

Material for the Foam inductor is bronze alloy with superb corrosion resistance and diffuser is composite (POM).

The Foam inductor generates vacuum and inject foam into the water line according to specified mixing ratio. The Foam inductor is equipped with a check valve to prevent water from accidentally entering the foam tank.

2 INSTALLATION

2.1 Safety precautions

The installation is uncomplicated, but must be performed by qualified personnel. The directives given in this manual must be followed closely.

Only use approved and certified lifting gear for performing lifting operation.

2.2 Inspection

Inspect the Foam inductor carefully for any signs of transport damage or other deviations which may have occurred during transport. Make sure that all equipment and parts are available.

2.3 Installation

The Foam inductor is for installation in the piping system between the water pump and the monitor(s). A typical installation is in a by-pass line around the discharge valve. The Foam inductor is of wafer type and is installed between two flanges with the diffuser part inserted in the pipeline (se picture below). Make sure the Foam inductor is installed in correct flow direction. Installation is recommended low as possible in the engine room, but normally not more than 3m higher than the bottom of the foam tank. Ensure straight pipe at least 0,5m before and 1m after the Foam inductor.

Place a standard gasket on each side of the Foam inductor and make sure that the correct

no. of bolts and nuts are available. Ensure gaskets is in place between the flanges before the bolts are inserted. Tighten the bolts in cross-sequence up to the recommended torque of 385 Nm.

Connect the foam pipe to the Foam inductor and ensure the pipe size to the foam tank is minimum same as the connection to the Foam inductor.

3 OPERATION

3.1 Start up and Commissioning

1. Ensure the foam tank is filled with foam liquid (alternative water or test foam for testing).

2. For FFS Foam inductors FFS-FiA (Adjustable), select the correct foam consentrate setting by the handle. For the FFS-Fi (not adjustable), the foam consentrate setting is fixed by factory.

3. Run the monitors with water and switch to “Foam mode” / ”Reduced Capacity” if applicable.

4. Open the main valve for the Foam inductor.

5. Ensure water is only running trough the inductor by closing other valves installed by-pass the

Foam inductor (i.e. main discharge valve, by-pass discharge valve).

6. Ensure the pump is running with correct pressure (operating speed).

7. Open the foam suction valve.

8. Check foam is coming out of the monitor or other foam equipment.

9. Check valves are in correct position after running the Foam inductor.

3.2 Trouble shooting

If no foam is produced during operation check the following:

1. Ensure the valves are in correct position.

2. Ensure the pump is running with correct pressure.

3. Check no air is coming into the foam line trough leaking flanges, valves or connections.

4. Check the suction line is not blocked.

5. Ensure the check valve on the Foam inductor is not jammed.

6. Check the counter pressure on the Foam inductor outlet is not more than 2/3 of inlet pressure.

If the counter pressure is too high, the monitor nozzle may be adjusted to higher capacity.

4 MAINTENANCE AND INSPECTION

4.1 Maintenance

The Foam inductor does not require any regular maintenance.

4.2 Inspection

Visually inspect the Foam inductor for any occurred damages, 5 REFERENCES

Droplet Adjustment

Box 369

The FFS-1200/300 and FFS-600/150 dual flow monitors are equipped with a flow regulating Droplet in the nozzle of the monitor for adjusting the capacity. Normal operation is to adjust the capacity to reduced when running with foam (Droplet in outer position). The pressure will then increase and in some cases the counter pressure is too high for the Foam Injector and foam will not be injected into the water. The Droplet must then be adjusted to increase capacity (reduce counter pressure), ref. doc. FFS-239 ch.3.2.6.

Adjusting Droplet:

1. Dismantle the Nozzle (FFS-1200/300 shown below, FFS-600/150 Nozzle including barrel)

2. Pull out the Droplet by hand to get access to the Lock Nut

3. Loosen the Lock Nut and turn it at least 3 turns CW (seen towards monitor outlet).

4. Turn the Droplet 2 turns CW (seen towards monitor outlet).

5. Tighten the Lock Nut.

6. Assemble back the Nozzle

Test the foam system. If still not working repeat procedure 1-6 one more time. If still not working, contact

FFS.
