9.0 CCS FILLING SEQUENCE
Before starting the fill procedure, attach the following:
a. 3/4” clear, flexible hose to Valve No. 4 and terminate in a 55 gallon drum.
b. Water source to Valve No. 6 (garden hose).
Refer to the appropriate concentrate schematic for valve descriptions.
Step 1: Close all valves except No.’s 4, 5, 6, and 7, and fill line master shut-off (Valve No. 11 for AFFF units, Valve
No. 9 for ARC units), WHICH MUST BE OPEN.
Step 2: Fill the shell with water through Valve No. 6 (do not exceed 25 PSIG water pressure) until a steady full flow
occurs from Valve No. 4. DO NOT CLOSE VALVE No. 4 WITH LINE WATER PRESSURE ON VALVE NO.
6. CLOSE VALVE NO. 6, THEN CLOSE VALVE NO. 4.
Step 3: Check for water at Valve No. 7. If water has appeared, and if water flow continues, consult the CCS supplier
before proceeding. If no water appears, proceed to next step.
Step 4: Close Valve No. 7.
