Page 5: Section 1 - Scope
The solenoids can be controlled by manual switching or in automatic mode via a remote signal. The flow of water initiates the operation of the dosing feeder which then injects the SFoam dust suppression chemical in to the water line. The solution concentration can be manually adjusted at the dosing feeder head between 0.2% and 1.6% concentration.

However, if the expansion chambers are installed 5 metres or more above the SFoam unit then higher supply pressures will be required. As a “rule of thumb”, water pressure should be increased 50 kPa for every 5 metres of elevation.
Page 10 Mechanical Installation  Install the SFoam Junior/Senior at ground level on a level site with good access to the required services.  The SFoam Junior/Senior unit comes complete with Ø25 mm male screwed BSP connections for the water and air lines and a Ø12 mm N.B. tube connection for the chemical line.
Page 11: Section 3 - Start Up And Commissioning
SECTION 3 – START UP AND COMMISSIONING First Time Startup (Commissioning)  Ensure that SFoam chemical, air and water are available to the unit. That is, all valves in the delivery lines are in the OPEN position.  Ensure that the red “POWER” on lamp is illuminated.
Page 12: Section 4 - Shut Down
 Turn the “AUTO/OFF/MANUAL” selector switch to the “MANUAL” position.  Run the SFoam unit for a few minutes or until it is apparent that all lines have been flushed clean.  Turn the “AUTO/OFF/MANUAL” selector switch to the “OFF” position.
Page 13: Section 5 - Trouble Shooting
SECTION 5 – TROUBLE SHOOTING When troubleshooting a typical SFoam installation, it is strongly recommended that a portable pressure gauge be carried so water and air pressures can be checked at various points in the system. PROBLEM DESCRIPTION ACTION Poor foam quality – runny, wet foam Insufficient air supply.
Page 14: Section 6 - Maintenance
SECTION 6 - MAINTENANCE Typically, the SFoam unit should require minimal maintenance, however, regular inspection to confirm correct operation is recommended. All maintenance procedures should be performed with the unit shut-down. Refer to the temporary shut-down procedure. Cleaning and Preventative Maintenance Intervals...

Page 16 The customer should also be able to guarantee the supply of a minimum of 40 l/min of water for a SFoam Junior and 75 l/min of water for a SFoam Senior. In practice, the SFoam unit may use less than this but if these quantities are not guaranteed prior to installation then problems may be encountered requiring the installation of a booster pump.
Page 17 Typical Dosing Points The best points for the application of SFoam are at the feed point of crushers, inside conveyor transfer chutes and similar points where the action of the material will tend to mix and thoroughly coat the material with foam before the dust has been created. It is too late to try and treat the material after the dust has been generated.
Page 18 APPENDIX B ESS Engineering Services and Supplies Pty Ltd – Site Service Log Sheet Note: SFoam unit must be inspected whilst operating. If unit is not operating, obtain site managers approval to operate in “Manual” mode for inspection and testing.
