Restaurant System Service Technician Responsibilities
Service technicians keep restaurant suppression systems operational and reliable. Here are some tips to help you do your job according to code.
Owner’s Manual
The system owner is required to keep a copy of the system owner’s manual in the restaurant and make it available if requested by the authority having jurisdiction. Make sure to carry extra copies and provide
them to customers as needed.
Flush and Blowout Piping
After a system has discharged, the system piping must be flushed with clean water and then blown out with dry air or nitrogen. Nozzles must be dry, free of agent, and installed in proper locations
with caps or foils.
System Recharge
System recharging is performed after any system discharge and when insufficient pressure is indicated on the system pressure gauge. System recharging is also performed after the 12-year hydrostatic test.
Old wet chemical is removed and replaced with new extinguishing agent. Only the agent marked on the system agent container is permitted to be used for recharging. No substitutes are permitted. Wet chemical is kept in the original shipping
container until recharging is performed.
Service Manual
Maintenance is performed every 6 months in accordance with the system manufacturer’s design, installation, and maintenance manual. The manual should be available for every service call.
Service Collar
Maintenance service collars are installed on stored pressure cylinders indicating the month and year of service using a hand punch. Service collars are not installed on cartridge-operated containers. Service
collars should be inspected monthly.
Maintenance Report
After completion of the semi annual maintenance, the owner must be provided a maintenance report including any corrective actions taken and recommendations. Maintenance reports must be kept by the owner
for one year.
These tips will help you do your work according to code. Remember to keep these things in mind for your next service call. Click here for a Restaurant Systems Monthly Inspection check off list.
