Those who install, operate, recharge, or maintain these fire sup- pression systems should read this entire manual. Specific sec- tions will be of particular interest depending upon one's responsibilities. Design, installation, recharge, and maintenance of the system must conform to the limitations detailed in this manual and per- formed by an individual who attended an Ansul training program and became trained to install, recharge, design, and maintain the Ansul system. Fire suppression systems are mechanical devices. They need periodic care. Maintenance is a vital step in the performance of your fire suppression system. As such it must be performed in accordance with NFPA 96 (Standard for the Installation of Equipment for the Removal of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment) and NFPA 17A (Standard on Wet Chemical Extinguishing Systems) by an authorized Ansul distributor. To provide maximum assurance that the fire suppres- sion system will operate effectively and safely, maintenance must be conducted at six-month intervals, or earlier if the situa- tion dictates. Twelve-year maintenance must include agent tank hydrostatic testing. ANSUL PART NO. 418087-08 ANSUL, ANSUL AUTOMAN and ANSULEX are trademarks of Ansul Incorporated or its affiliates.

Those individuals responsible for the design of the R-102 system must be trained and hold a current Ansul certificate in an R-102 training program.

These limitations should also be referred to when selecting the mounting location for the regulated release mechanism and agent tank. General Piping Requirements 1. All R-102 system piping is straight line. Therefore, the need for critical lengths and balancing is minimized. 2 Two 45° elbows count as one 90° elbow. 3.

Tape should be applied to male threads only. Make certain tape does not extend over the end of the thread, as this could cause possible blockage of the agent distribution. 8. Before installing blow-off caps on nozzles, apply a small amount of Dow Corning No. 111 silicone grease across the REGULATED opeing in the nozzle tip and also a small amount coating the ACTUATOR exterior of the blow-off cap. This will help keep cooking grease ASSEMBLY FIGURE 85 from building up on the cap. ? 000777 SECTION IV - SYSTEM DESIGN UL EX. 3470 ULC CEx747 Page 4-47 3-1-04 REV.3 DISTRIBUTION PIPING REQUIREMENTS (Continued) Supply and Branch Line Identification SUPPLY LINE The R-102 distribution piping network is broken down into four The Supply Line is defined as the length of pipe which runs from specific pipe runs: the Supply Line, the Duct Branch Line, the agent tank outlet to the last branch line (whether a duct, appli- the Plenum Branch Line, and the Appliance Branch Line.
