3 Warning AFTER A FIRE, DO NOT PERFORM ANY MAINTENANCE UNTIL THE EQUIPMENT HAS COOLED SUFFICIENTLY. WORKING ON THE EQUIPMENT BEFORE IT HAS COOLED MAY RESULT IN BODILY INJURY AND / OR DEATH. NEVER USE WATER TO BLOW OUT DISTRIBUTION PIPING. RESIDUAL MOISTURE MAY CAUSE CORROSION AND RESULT IN DISTRIBUTION SYSTEM RESTRICTION AND/OR BLOCKAGE. NEVER USE OXYGEN TO BLOW OUT DISTRIBUTION PIPING. OXYGEN MAY EXPLODE IF CONTACTED BY OIL. Before Activating the Kiddie Fire system check for faults that caused the system to expel fire suppression and repair 3

4 Dry chemical, when discharged, will drift from the immediate discharge area and settle on surrounding surfaces. Prompt cleanup will minimize possible staining or corrosion. Caution: Eye protection, dust mask, and gloves is recommended during clean up. Note: All information provided in this Grab N Go are from the Kiddie Maintenance Manual. For more detailed information please refer to the Kiddie System Manuals. 4

5 1. Install the protective caps on the outlet port of all cone nozzles to prevent the introduction of foreign material into the distribution system while removing the discharged dry chemical extinguishing agent from the vehicle surfaces. On Van Hool coaches there are 4 protective caps 5

6 2. Brush, blow, vacuum or wash all discharged dry chemical extinguishing agent from all vehicle surfaces.!caution! Eye protection, dust mask, and gloves are recommended. 6

7 3. Unplug the electrical connector from the extinguisher assembly. 4. Unscrew the distribution hose from the discharge adapter on the extinguisher assembly. 7

8 After System Discharge 5. Unscrew the anti-recoil cap from its storage point on the extinguisher bracket and install it on the valve outlet port on the extinguisher assembly. 6. Remove the extinguisher assembly from the extinguisher bracket and set aside. Refer to the Kiddie manual on replacing the bottle. 8

9 7. Unscrew all cone nozzles. Blow off with DRY air or DRY nitrogen. Verify no obvious physical damage or condition exists that might prevent normal operation. Replace any cone nozzle or protective cap that was exposed to direct flame or subjected to excessive heating.! WARNING! NEVER USE WATER TO BLOW OUT DISTRIBUTION PIPING. RESIDUAL MOISTURE MAY CAUSE CORROSION AND RESULT IN DISTRIBUTION SYSTEM RESTRICTION AND/OR BLOCKAGE.! WARNING! NEVER USE OXYGEN TO BLOW OUT DISTRIBUTION PIPING. OXYGEN MAY EXPLODE IF CONTACTED BY OIL 9

10 8. Connect a pressurized DRY air or DRY nitrogen source to the distribution hose that was removed from the discharge adapter on the extinguisher assembly. Blow out the distribution piping until residual dry chemical extinguishing agent no longer discharges from any of the distribution piping terminations. 10

11 9. Inspect the entire distribution system. Verify no obvious physical damage or condition exists that might prevent normal operation. Replace any hose, fitting, tee, elbow, distributor or nozzle bracket that was exposed to direct flame or subjected to excessive heating. 11

12 10. Re-install all cone nozzles with protective caps in place 12

13 11. Obtain a NEW or REBUILT extinguisher assembly and double check the extinguisher nameplate to ensure it is the correct configuration for the intended application (dry chemical extinguishing agent type and gauge location). Also double-check that the extinguisher pressure gauge pointer is in the green arc at room temperature (70 F). NOTE: Depending on your coach model Bottle location and hose routing can be different. Refer to the appropriate manual for your selected Coach. 13

14 12. Before your Kiddie system is ready for use. Check to see what caused the discharge. Fire accidental discharge. Fire: Must find what was the cause and repair. If thermal wire was damage it must be replaced. 14

15 Accidental Discharge: Replace the safety pin clip on the manual discharge fire button located in the drivers compartment. 13. Once the system faults have been repaired. The last step is to check the fuse for the system located in the battery compartment. Remove the fuse and inspect. Replace if needed 15
