If there are no provisions for testing the operation of the flow detection device on the system, application of the <br /> VSR-F is not recommended or advisable. <br /> i i. . <br />� A minimum flow of 10 gpm (38 Lpm)is required to activate this device. <br /> IMPORTANT NOTICE: Please advise the person responsible for testing of the fire protection system that this system must be <br />, tested in accordance with the testing instructions. <br /> PRINTED IN USA MKT #8800001-REV W PAGE 2 OF 2 <br /> MFG.#5400761-7/02 <br /> ;I <br />
