Fire Extinguisher-Charging

NOTE: Water fire extinguisher is shipped uncharged. Prior to delivery of machine the water fire extinguisher must be charged.

When an antifreeze charge is used to freeze protect extinguisher, a complete discharge and maintenance is required.

causym CAUTION: Before attempting to recharge ensure that extinguisher is completely depressurized.

1. Discharge all remaining pressure and water (or antifreeze solution) making sure there is no remaining air pressure.

2. Loosen nut (A) and remove valve assembly (B) from cylinder (C).

IMPORTANT: Fire extinguisher must not be exposed to freezing temperatures unless protected with antifreeze. See instructions decal on extinguisher for further information.

NOTE: Corrosion inhibitor must be used, if water includes high levels of chlorides (40 ppm).

3. Fill cylinder with clean water or antifreeze solution until it overflows 9.5 L (2.5 gal.).

causym CAUTION: Hand tighten nut to specification. Over tightening with wrench will damage valve.

4. Install valve assembly (A) and tighten nut (B) to specification.

Specification

Nut -Torque 11.3-11.9 N·m (100-105 lb-in)

5. Remove cap from pressurizing valve (C).

NOTE: Set pressure regulator on air compressor to no more than 175 kPa (1.75 bar, 25 psi) higher than gauge operating pressure.

causym CAUTION: Never leave fire extinguisher connected to a regulator of a high-pressure source for an extended period of time. Do not over pressurize fire extinguisher. Fire extinguisher may rupture if over pressurized.

6. Pressurize fire extinguisher to specification using air or nitrogen.

Specification

Fire Extinguisher -Pressure 690 kPa 6.9 bar (100 psi)

NOTE: Check nut, gauge, pressurizing valve, cylinder welds and valve orifice for leaks using leak detection fluid or a solution of soapy water.

7. Install previously removed cap on pressurizing valve.
