TOP ASSEMBLY ROTATION All Automatic Shutoff Valves are shipped as standard in a configuration compatible with conventional piping, but if OPEN/ SHUT indicator is not visible when valve is installed, top assembly can be rotated (in 90° increments) by following procedure below for either 1516 Manual Reset or 1517 Motorized Valves. Operating personnel should become familiar with characteristic opening/closing action of the valve. Should operation ever become sluggish, remove valve from service and contact North American for replacement recommendations.

ALL 1517 VALVES 1. Shut off all electrical power to valve and close upstream gas or oil cock. 2. Remove terminal block cover and disconnect incoming lead wires (tag carefully for reassembly). 3. Remove conduit and leads. 4. Remove sideplate and carefully note position of signal switch wands. 1 8 5. Unscrew the actuator bolts (two or four depending on valve size) to ¼ ", with 5⁄16 " 12-point box wrench ( 3⁄8 " for valves 2" and larger). Do not completely remove. These bolts secure the valve body to the valve's top assmbly housing. 2 6.Gently lift top assembly NOT MORE THAN ¼", just enough to break the seal between valve body and the Buna "N" rubber gasket . WARNING : Lifting too far may dislodge some small parts inside the top housing, requiring complex reassembly and retesting by trained factory personnel. 8. Carefully rotate top assembly about 30° beyond, and then back to the desired position, in a plane parallel to the top of body casting . This should align OPEN/SHUT indicator with its window and the latch arm roller of operating mechanism with its pedestal. 3 5 7. Remove the two actuator bolts , (that were partially re- moved in step 5). 2 3 5 4

9. Align screw clearance holes in valve body casting with the corresponding tapped holes in the bottom of top assem- bly . 10. Reinsert body screws , carefully engaging threads, and tighten securely. 11. Reconnect conduit and electrical leads. 2 3 MAINTENANCE INSTRUCTIONS Oil shutoff valves are endurance-tested and they are designed for long life even if frequently cycled, and to be as maintenance and trouble-free as possible. Every valve is operationally tested and meets the requirements of ANSI B16.104 Class VI Seat Leakage when it leaves our plant WARNING: Do not attempt field repair of valve body, top assembly, or motor drive unit. Any alterations void all war- ranties.
