11 <br />C] <br />Installation Guide Conditions of Approval for City of New York Certificate of Approval #4942 <br />In ft"M101MM, <br />Special Installation Instructions <br />To minimize the chance of experiencing any disruption in the dispensing operation and <br />maximize the benefits of this Red Jacket leak detector, please read this appendix. <br />It is very important that all of the dispenser solenoid valves in the system in which this leak detector will <br />operate remain closed for approximately four seconds every time the submersible pump is activated. The leak <br />detector can only perform a line test during this four -second window. <br />This test requires approximately two to four seconds, depending upon conditions present in the system. The <br />dispenser solenoid valve must stay closed until the test is completed. This may be accomplished by utilizing <br />delays integral to electronic dispensing equipment or by installing a retrofit delay in the junction box. <br />Past experience has shown that without this delay the leak detector has insufficient time to complete its line <br />test and provide uninterrupted service. <br />Contact Red Jacket technical service at 1-800-323-1799 with any questions concerning this procedure. <br />U <br />
