MAINTENANCE
AFTER FIRE HAS BEEN EXTINGUISHED
1.
Make certain that horn valve is left open until all pressure is relieved from hose.
2.
Remove the empty cylinders and have them recharged immediately. See instructions for removal of cylinders
elsewhere in this book.
3.
Rewind hose on rack or reel and replace horn in clip. The valve must be left in its closed position.
4.
For remote control systems, pull the control cable back and forth between the cylinder(s) and break-glass pull box
to make certain it operates freely. Replace glass at the pull box.
PERIODIC INSPECTION
Kidde equipment requires no more than ordinary care to insure its proper operation at all times. Frequent inspections,
however, should be made to determine the exact condition of the apparatus.
ONCE EVERY MONTH
Make a general inspection of the equipment to make certain that nothing has been placed to interfere with the operation of
equipment. The discharge horn and reel or rack, also, should be unobstructed.
Inspect piping and hose for any mechanical damage. Operate horn valve several times to make certain it does not stick.
The valve should be left in its closed position.
ONCE EVERY YEAR
It is recommended that the system be inspected by a service engineer of Walter Kidde & Company, Inc.
The Kidde cylinders should be removed and weighed to determine the carbon dioxide content. (Do not attempt to
determine content by using a pressure gauge.) See instructions for removal included in this book before proceeding. The
tare weight should be subtracted from the charged weight stamped on the valve body. This resultant weight is the actual
weight of the charge, and should this have decreased by more than 10% of the charged weight assembly should be
recharged. Record the net weight of the gas in each cylinder on record sheets included in this book.
ONCE EVERY TWO YEARS
Blow out the entire system with air or carbon dioxide to make sure that it is not plugged. Be sure to run hose out to its full
length.
