AFTER AN ACTUATION
CLEAN-UP
Kitchen surfaces should be cleaned immediately after a system discharge due to the fire-suppressing agent’s alkaline
nature.
• Observing the recommendation and clearance from the fire officials, allow the system to cool down before
attempting to clean.
• Ensure all fuel or electrical sources to the equipment to be cleaned are OFF.
• Unplug the hood and all appliance’s electrical controls to avoid any risk of electrical shock resulting from the
cleaning process or from an electrically conductive liquid agent.
o Discard all food and cooking oil that has contacted the extinguishing agent. It is no longer suitable for
consumption.
• Wipe agent off with paper towels or rags removing as much excess agent as possible
• Use hot, soapy water to clean away residue on all surfaces that the agent has come into contact with.
• Completely dry all areas before continuing Maintenance procedure
INSPECT THE UNIT
Ensure that no fire and/or smoke damage is present on any of the unit’s components
DETERMINE THE CAUSE OF THE DISCHARGE
Determining the cause of the system’s discharge before replacing the fire-suppression system and re-setting the unit is
critical to ensure the system performed correctly, or if there is evidence of malfunction.
NOTE: Contact the manufacturer before continuing if a malfunction is suspected.
Potential Causes:
• The fusible links have been melted by a fire, causing the system to discharge.
o If there is evidence of a fire inspect the electrical system and wiring for heat damage.
• The remote pull station (optional) was pulled.
• If fusible links are over 6 months old or have expired, they may have stretched causing the actuation cable to
be released.
RESET THE SYSTEM
• Refer to local codes in bringing the system back to operation.
• Remove the extinguisher tank and replace with a test tank (see Page 22).
• Remove the fusible links from the actuation cable assembly and replace links with new properly rated links
and one test link at the terminal end (see Page 22).
• Return the tanks discharge paddle and actuation cable to the set position.
• Replace the nozzles.
• Using wire cutters, cut the test link at the terminal end to simulate an actuation.
• If the mechanism does not actuate, check the following and address as needed:
o The fusible links are in the correct position through pulleys.
o No twists or knots are present in the actuation cable.
o Ensure that the actuator arm is in place and in the set position.
o Verify the safety pin is removed from the tank and the safety key has been removed.
o Re-test the system after installing a new test link on the terminal end.
o If problems persist contact the manufacturer.
• Once the system actuates successfully replace the test tank with a fully charged tank and replace the test
link with the correct fusible link.
WARNING
:
Safety glasses and gloves must be worn for all operations. Flush thoroughly with water
if agent comes in contact with skin or eyes.
