FOREWORD
This manual is intended for use with PYRO-CHEM KITCHEN
KNIGHT II Restaurant Fire Suppression Systems.
Those who install, operate, recharge, or maintain these fire
suppression systems should read this entire manual. Specific
sections 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 a PYRO-CHEM training
program and became trained to install, recharge, design, and
maintain the PYRO-CHEM 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 PYRO-CHEM distributor. To provide maximum
assurance that the fire suppression system will operate effec-
tively and safely, maintenance must be conducted at six-month
intervals, or earlier if the situation dictates. Twelve-year main-
tenance must include agent tank hydrostatic testing.
