For Domestic And International Use: HFC - 227.
You should frequently check the fire extinguisher for the correct pressure. If the pressure is below
specification, have the unit serviced.
You should also weigh the cylinder (less the bracket) for proper weight. If the gross weight has deviated
from the specification label, service or replace the fire bottle. Weigh the cylinder at least twice a year.
