ARMING YOUR SYSTEM

Insure release valve latch is engaged (See FIGURE below) and remove the cylinder valve safety pull pin from the extinguisher cylinder assembly (FIGURE 22) to arm system.

CAUTION: Refer to initial installation, system checkout, activation instructions in this manual for repositioning / re-aiming the nozzles and sensors anytime they are moved, removed, or reinstalled. (See FIGURES 18-21)

AFTER A DISCHARGE

IN THE EVENT A FIRE SHOULD OCCUR AFTER THE GUARDIAN III SYSTEM HAS BEEN INSTALLED AND EXTINGUISHED A FIRE, PROCEED AS FOLLOWS:

RECHARGE / REACTIVATION OF SYSTEM

CAUTION: Before replacing the fire suppressant agent, the extinguisher cylinder, release valve assembly, or other system components, it is recommended to wear approved type eye protection and rubber gloves.

1. Remove the 9V DC battery from the CPU board.

2. Disconnect heat sensor 1 & 2 terminal wire connections from the CPU board and remove the heat sensors from underneath the range hood. Both heat sensors may be required to be replaced with new heat sensors (Part #G305A30 and G305B54)

NOTE: Insure pressure gauge indicator needle is in the "Recharge area of the gauge face prior to disconnecting the quick connect.

3. Disconnect the quick connect at the magnetic base with Tee Assembly and remove the distribution assembly from underneath the range hood.

4. Thoroughly flush distribution assembly with water to remove any residual fire suppressant. Inspect distribution assembly (hoses, fittings, nozzles) for leaks or other damage and wipe dry with a clean cloth. Set assembly aside and let completely dry.

NOTE: If leaks or other damage are found in the distribution assembly, do not reinstall distribution assembly until those parts, which are leaking or damaged, have been replaced. See Parts List, Page 15, if required.

5. Disconnect extinguisher cylinder release valve terminal wire connections from the CPU board (see FIGURE 3, Page 5) and remove the extinguisher cylinder assembly from the enclosure base.

6. Unscrew and remove the extinguisher cylinder manifold / siphon tube assembly from the extinguisher cylinder. Pour out any residual fire suppressant, which may be left in the extinguisher cylinder.

7. Refill extinguisher cylinder with 5 lbs. (58 oz.) of Ansulex Low pH (Part #79372) fire suppressant.

8. Replace the extinguisher cylinder manifold "0" ring (Part #G303-D) and reinstall manifold / siphon tube assembly into the extinguisher cylinder. Do not combine / mix chemicals or suppressants.

CAUTION: Do not use extinguisher cylinder gauge to determine when the intended charge pressure has been reached.

9. Connect a nitrogen supply line to the 1/4" male quick connect fitting and pressurize to 100 PSI.

10. Reinstall the extinguisher cylinder assembly in the enclosure base.

11. Refer to initial installation / system check-out / activation instructions to complete reinstallation / reactivation of the system. See FIGURES 3, 18, 19, 20, 21, and 22, Pages 5, 11,12 and 14.
