Proper shutdown procedures prolong the life of the CAFSPro system and ensure
the system is ready for operation when needed.
5.1 FOR SYSTEM SHUTDOWN
1. Turn the air injection OFF by pressing the i (ON) button on the CAFSPro
control unit.
The display reads STBY.
2. Turn the Hale FoamLogix foam proportioning system OFF by pressing
the
i
button on the control unit. Also see FoamLogix Operation and
Maintenance Manual, Hale p/n: 029-0020-68-0.
Note: If Class “B” foam concentrate was used during operations, flush the Hale
FoamLogix using procedures in the operation section of the Hale FoamLogix
Operation and Maintenance Manual, Hale p/n: 029-0020-68-0.
Return selector to Class “A” position.
3. Flush all hoses clear of all foam residue.
Establish water flow through the CAFS and/or foam solution hose lines and
flush until discharge is clear.
4. Close discharge valves.
WARNING !
ALWAYS OPEN NOZZLES SLOWLY WHEN FLOWING A CAFS HOSE LINE.
ADDING COMPRESSED AIR TO THE HOSE LINE DRAMATICALLY
INCREASES THE ENERGY CONTENT. HOSE LINES CHARGED WITH COM-
PRESSED AIR FOAM HAVE VERY LITTLE WEIGHT BUT CONTAIN LARGE
AMOUNTS OF ENERGY. NOZZLE REACTION GREATER THAN THAT OF
PLAIN WATER IS TO BE EXPECTED.
IT IS ACCEPTABLE TO LEAVE THE FOAM SELECTOR IN THE CLASS “A”
POSITION. WHEN APPROVED CLASS “A” FOAMS ARE USED READ AND
FOLLOW THE MANUFACTURER’S DIRECTIONS ON FREQUENCY OF USE TO
AVOID SYSTEM PROBLEMS.
