Installation Pressure Relief Procedure Pre–Installation Procedure 1. Install the battery. See Replacing the Battery on page 31. 2. Follow the Pressure Relief Procedure. The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the dispense valve, or splashing fluid, follow this Pressure Relief Procedure when you: • • • 3. Close the shut–off valve (B, FIG. 1, page 5). 4. Ground the hose and reel or console.
Installation 4. a. Place the hose end (with no dispense valve connected) into a container for waste oil. b. Secure the hose in the container so it will not come out during flushing. c. If you have multiple dispense positions, first flush the dispense position farthest from the pump, then work your way toward the pump.
Installation Installing Extension and Nozzle on Meter B 26a 26c 26b ti12081a FIG. 8 FIG. 7 1. Thread the sealing nut (26c) onto the extension (26a). 2. Thread extension into meter outlet at least three full turns to tighten securely. (FIG. 7). (Over torquing may cause casting meter to split) NOTICE • Do not overtighten extension to sealing nut.
