What documentation must a service technician have to service the wet chemical fire-extinguishing system?

• A. The owner's manual
• B. The applicable manufacturer's design, installation, and maintenance manual and service bulletins
• C. The warranty certificate
• D. The system listing certificate

Answer: (B)

The needed documentation is the manufacturer’s design, installation, and maintenance manual plus any service bulletins. Wet chemical systems are purpose-built for specific hoods and kitchens, with exact procedures for inspection, testing, recharge, and replacement parts tailored to that model. Having the current manual ensures the technician follows the correct steps, understands the correct agent quantities, and follows any updates or recalls issued in service bulletins. Relying on a generic owner’s manual or a warranty certificate does not provide the detailed, model-specific instructions required for safe and compliant service, and a system listing certificate only confirms approval, not how to service it.
