Before operating foam system, personnel must familiarize themselves with all
procedures and instructions regarding water pump, discharge devices, and foam
making devices. Failure to understand and follow any instructions could result in
injury to personnel and/or damage to equipment.
Open and close all valves slowly during any procedure. Sudden changes in
pressure may cause equipment to react faster than personnel can be alerted.
Ensure surrounding personnel are aware of changes being made to settings on
equipment. Failure to comply may result in injury or death to personnel and
damage to equipment.
CAUTION
When in foam mode, never open TANK FILL & RE-CIRCULATION LINE valve control.
This will cause foam agent to enter water tank. If re-circulation is needed to keep
pump cool, open PUMP COOLER valve.
Foam system operation from pump operator's panel requires system pressure of at least 125 to 250 psi (862 to
1,724 kPa) for proper proportion.
