MAINTENANCE
MAINTENANCE
If a questionable condition exists, refer to Service and
Repair. Become familiar with the Service and Repair
section prior to performing maintenance.
To provide maximum assurance extinguisher will operate
effectively and safely, maintenance must be conducted
annually or when specifically indicated by an inspection.
NOTICE
Always be alert for any indications of damage
or in-operability in the unit. No manual can
anticipate everything that could happen to a
unit. In the event that something not covered
in the manual is found, ascertain whether
any potential for damage exists and repair or
replace, as necessary.
1. Make certain the extinguisher is in its designated
place, conspicuous, readily accessible and immediately
available in the event of fire.
2. Remove the extinguisher from its wall hanger or bracket.
Check the securement of the hanger or bracket. See
page 19 for maintenance of the extinguisher bracket. A
loose hanger or bracket could lead to loss of the extin-
guisher with resultant harm to the extinguisher and/or
people in the vicinity.
NOTICE
Extinguishers out of service for maintenance
or recharge shall be replaced by spare extin-
guishers of the same type and at least equal
rating.
3. Check the date of manufacture stamped on the shell or
the date of last hydrostatic test on the label affixed to the
extinguisher to make certain it does not exceed the test
interval (twelve years) specified in the latest edition of
NFPA 10, Standard for Portable Fire Extinguishers.
4. Invert the extinguisher and open the nozzle to ensure that
any pressure is relieved from the shell.
5. Return extinguisher to the upright position, place the hose
in its normal position and insert the nozzle in the holder.
6. Examine the dry chemical shell and all other external
components for evidence of corrosion, mechanical
damage, or the presence of welding, soldering or brazing
repairs other than as allowed by Johnson Controls. (See
Introduction, page 1, of this manual for welding/brazing
restrictions.) Depending on the degree of corrosion,
extent of mechanical damage, or type of repair, the extin-
guisher may constitute a potential hazard to persons in
its vicinity, to operators, or service personnel; and may
require replacement or hydrostatic test.
