Maintenance Overview;

     This chapter will detail the basic procedures for proper maintenance of the Kitchen Fire Suppression System. Maintenance of the system must be in compliance with the parameters set forth in this manual and be performed by a factory trained, Authorized company of the product. The producer company is not responsible for systems installed or maintained by personnel that are not factory trained and Authorized.

Owners Inspection;

Monthly;

• Monthly inspections shall be performed as per NFPA-17A and are required by producer comnpany. On a monthly basis the owner of the Fire Suppression System must perform the following “quick check” to verify the following:
• The extinguishing system is in its proper location.
• The manual actuators are unobstructed.
• The tamper indicators and seals are intact.
• The maintenance tag or certificate is up to date and in place.
• No obvious physical damage or condition exists that might prevent operation.
• The pressure gauge is in the operable range.
• The nozzle blow off caps are intact and undamaged.
• The hood, duct, and cooking appliances have not been replaced, modified, or relocated.
• If any deficiencies are found the owner is to contact an Authorized Service immediately.

Note: A record of monthly inspections is to be kept by the owner of the system that includes the date of inspection, the person performing the inspection, and any corrective action required.

Semi-Annual Maintenance;

• Semi-annual maintenance of the System is required by NFPA-17A and producer company and must be performed by a factory trained, authorized company. Semi-annual maintenance shall include the following:
• Check that the hazard area has not changed.
• Check entire system for mechanical damage.
• Check all nozzle orifices to assure that they are unobstructed and that all nozzle caps are in place.
• Nozzles must be completely unobstructed and show no signs of internal blockage. If nozzle(s) show any signs of internal damage or blockage, remove nozzle from service and replace with a new nozzle
• Disconnect the Systems Releasing Module or pneumatic tubing from the valve cap of each agent cylinder.
• Remove the face plate from the control head and insert the keeper pin in the hole above the piercing pin in the cartridge manifold.
• Remove the actuation cartridge from the systems releasing module and then the keeper pin.
• Activate the Systems Releasing Module by releasing tension from the end of the fusible link line. Make certain that the Systems Releasing Module fires and the gas valve closes.
• Reset the Systems Releasing Module and then activate the system by using the remote pull station. Make certain that the Systems Releasing Module fires and the gas valve closes.
• Inspect the fusible links and fusible link detection line for grease build-up or mechanical damage. Replace links, corner pulleys, or conduit if necessary.
• Check the cylinder pressure gauge, making sure it is in the operable range.
• Install the Nitrogen Actuation Cartridge, and then reconnect the Systems Releasing Module to the cylinder valve or pneumatic tubing.
• Remove the keeper pin from the Systems Releasing Module and replace the Systems Releasing Module cover. Verify that the date on the cartridge is visible in the viewing window.

Note: Annual maintenance of the system is required by NFPA-17A and producer company and must be performed by a factory trained, Authorized services. Annual maintenance shall include the following:

Annual Maintenance;

• Inspect and test in accordance with steps 1 – 11 of semi-annual maintenance instructions.
• Disconnect the discharge piping from the cylinder valve. Using air or nitrogen, blow out the discharge piping and make sure all the nozzle caps have blown off. If any nozzle cap(s) fails to blow off during test, carefully examine piping system and nozzle to determine cause and take appropriate corrective action. Repeat test to assure both piping system and nozzles are unobstructed.
• Replace all fusible link detectors.
• Replace the Nitrogen Actuation Cartridge being sure to write the current date in the space provided.
• Reconnect the Systems Releasing Module to the cylinder valve or pneumatic tubing.
• Remove the keeper pin from the Systems Releasing Module and replace the Systems Releasing Module cover. • Verify that the date on the cartridge is visible in the viewing window.

12 Year Maintenance;

     In addition to the required annual maintenance, all agent cylinders must be removed from the system, discharged, and hydrostatically tested as per the requirements of NFPA-17A. The cylinder should then be recharged in accordance with this manual and returned to service.
Note: New extinguishing agent must be used when performing this procedure.
