2.2 Ensure the cylinder charge pressure is between 60 and 75 bar and that the security pinis in place.

IF ANY ABNORMALITIES ARE APPARENT, SEND THE UNIT FOR REPAIR.

3 RECHARGING

Ensure the extinguisher is completely discharged.

3.1 Remove the discharge hose from the trigger valve and remove the trigger valve fromthe cylinder.

NOTE

Due to the affect of adiabatic heating, the extinguisher pressure will drop slightly as thecylinder cools after charging. Top up as required.

3.7 Vent and disconnect the charging hosewhip and check the extinguisher for leaks.

3.8 Install the security pin.

3.9 Install the discharge hose, hose adaptor and gasket, ensuring the gasket is in goodcondition and tighten all fittings securely. Replace the gasket if necessary, Part No.1835.

4.2 Ensure the extinguisher is completely discharged and remove the trigger valve.

4.3 Examine the extinguisher valve assembly for apparent mechanical or corrosiondamage to the pressure gauge, valve mechanism and discharge nozzle. Ensure thedischarge lever can move freely and that no part of the mechanism has beendamaged. If damaged, replace with new.

4.4 Ensure that the security pin can be easily inserted and withdrawn.

4.5 Examine the cylinder internal surfaces in accordance with BS 5430 Part 3 or anequivalent recognised standard. Check for excessive radial pitting at the waterline orcorrosion damage to the neck thread.

4.6 Replace the trigger valve O-ring, Part No. 02529 as required. Lightly lubricate withDOW CORNING III silicone compound.

4.7 The extinguisher is now ready for recharging. Refer to Recharging Instructionsparagraph 3.
