guisher has been subjected to extremes of heat or cold. High tem-
peratures can cause high gauge readings and low temperatures,
low readings. When in doubt, condition the extinguisher to 70ºF
(21ºC) for several hours to obtain more accurate pressure gauge
readings.
2.
Leak through valve
Remove valve assembly, downtube, spring and valve stem assem-
bly. Install new valve stem (GREEN SEAL) assembly. Check valve
seat for scratches or foreign matter.
