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 />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 /> <br />PRINTED IN USA <br /> <br />PAGE 2 OF 2 <br /> <br />MKT,#8800001-REVW <br />MFG, #5400761 - 7/02 <br />
