WARNING
When removing charged cylinders, always disconnect the discharge heads first.
This will minimize the possibility of accidentally discharging the CO

system,
which could result in possible equipment or property damage or injury to
personnel.
WARNING
Discharge head(s) must be left connected to the discharge hose and system
piping to prevent injury in the event of system discharge.
WARNING
Do not remove cylinder(s) from the bracketing if the valve protection cap is
missing. Obtain a new protection cap from Kidde Fire Systems or a distributor
of Kidde Fire Systems products.
