7. Check the nameplates for legibility, looseness or corro-
sion. If the wording is illegible, the nameplate must be
cleaned or replaced. A loose nameplate must be removed
for examination of the area under the plate. If corroded,
take appropriate corrective action as the surface condition
would indicate, meaning clean and repaint, hydrostatic
test and then re-affix the nameplate using a good grade
of heatless adhesive or replace extinguisher if necessary.
8. Remove cartridge guard and check integral inside compo-
nents for mechanical damage or evidence of corrosion.
“E” Models (Metal cartridge guard) –
Pull the guard
straight out from the side of the extinguisher.
“G” Models (Composite cartridge guard) –
To remove
the composite cartridge guard, remove the nozzle from
the nozzle retainer, lift the hose out from behind the punc-
ture lever, (it will be necessary to break the visual seal),
pull on the upper portion of the guard until it releases
from the cartridge, and then pull up until the bottom fork
of the guard clears the discharge elbow.
9. Unscrew the cartridge (turn in direction of arrow on
cartridge) to examine seal. Ensure that it has not been
punctured and it is the proper ANSUL cartridge and has
the proper ANSUL seal. A spent or used cartridge is
readily identifiable from a full cartridge by the large hole in
the seal, made by the puncture pin upon operation of the
extinguisher.
10. Weigh the cartridge. If weight is 1/4 oz (7.1 g) for Model
10 or 1/2 oz (14.2 g) for Models 20/30 less than stamped
on the cartridge, replace with full cartridge. Cartridges
which weigh more than 1/4 oz (7.1 g) over stamped
weight should also be replaced.
!
CAUTION
Do not return cartridge to receiver at this time. Failure to
comply could result in personal injury or property damage
due to violent cartridge movement or premature extin-
guisher pressurization.
11. Install safety shipping cap (Part No. 77250 for left-hand
and 77251 for right-hand threaded cartridges) onto
cartridge at this time.
!
CAUTION
Cartridge safety shipping caps must always be installed
whenever cartridge is removed from receiver (except
while weighing). If shipping cap is not installed, and seal
ruptures due to damage or high temperature, the cartridge
could become a projectile causing possible personal
injury or property damage.
12. Remove nozzle from its holder and lift hose out from
behind and under the puncture lever, breaking the visual
seal, and, if provided, the tamper-proof seal, at this time.
Note: On extinguishers with the composite guard, the
seals will already have been removed and the hose will
be out from behind the puncture lever.
