1.3 SAFETY PRECAUTIONS NFPA 30A states that: “When maintenance to Class I dispensing devices becomes necessary and such maintenance may allow the accidental release or ignition of liquid, the following precautions shall be taken before such maintenance is begun: • Only persons knowledgeable in performing the required maintenance shall perform the work. • All electrical power to the dispensing device and pump serving the dispenser shall be shut off at the main electrical disconnect panel.
2 2.1 INSTALLATION Inspect the Equipment Examine the shipment immediately upon arrival to make certain there has been no damage or loss in transit. Damaged or lost equipment must be reported to the carrier. Any damage or loss that may occur in transit is not covered under the Wayne/Dresser Warranty. Make sure that all the component parts, including keys and optional equipment (if any), are accounted for.
Figure 2-1 Typical Emergency Valve Installation. The Emergency valve is designed to close the product line due to shock or fire. The shear section, shown above, functions if the dispenser is knocked out of position. 6 Part No.
2.4 CHECK VALVES (SUCTION PUMPS ONLY) Suction pumps require a check valve in the product lines to stop product from draining back to the tank. Wayne recommends double poppet foot valves inside the underground tank. The foot valves should be the same size as the suction lines. Foot valves designed for handling petroleum products are equipped with a coarse mesh strainer screen. The bottom of this screen is blocked off so that the product enters the valve from the side.
2.6 Lifting and Installing the Dispenser Remove the dispenser from its shipping carton. Survey the site and determine if any special installation requirements, such as a canopy, will affect the installation. If the dispenser is equipped with an optional valance, survey the site to determine if it should be installed before or after the dispenser is set on the island. Wayne recommends installing the valance after the dispenser is installed, if practical, to protect it from installation damage.
2.7 Electrical Wiring 2.7.1 General Wayne recommends employing a qualified electrician for all wiring. A hazardous liquid is being handled, so it is important to ensure that all wiring is in accordance with the National Electrical Code (NFPA 70) as well as all federal, state and local regulations. Note that U.L. requires that all electrical connections to the dispenser be made with threaded, rigid conduit and properly sealed conductors.
2.7 Electrical Wiring, continued Figure 2-3 Location of Components in the Dispenser (Typical). Location may vary slightly by model. WARNING Electric Shock Hazard! No connections (including neutral) may be shared between groups of dispensers. A separate Control Power Circuit Breaker must be provided for each group. Failure to do so may result in serious injury. 10 Part No.
2.7 Electrical Wiring, continued 2.7.5 Dispenser to Wayne Control System Wiring For connection to a 2400 MCS or Wayne Plus follow the installation instructions supplied with that system. The installation wiring diagrams in Appendix C show two DATA wires to the Data Distribution Cabinet required for the 2400 MCS or Wayne Plus Console pump control operation, and two DATA wires to the Site Controller for Card Processing and/or cash acceptor operation.
2.8 Sale Display Lights The dispenser is delivered with the sale display lighting circuit connected to the control power circuit at the terminal strip in the dispenser junction box. The sale display lighting may be connected to a separate circuit breaker by making a wiring change at the terminal strip in the junction box; refer to the appropriate Installation Wiring Diagram in Appendix C. 2.9 Hose Installation Hose assemblies should be U.L.
2.11 Priming Suction Pumps Suction pumping units must be primed before their initial operation; it is not advisable to run any type of internal gear pump dry during the priming process. Insert a small quantity of light-grade oil (1/2 pint or 1/4 liter) through the priming plug in the pumping unit before starting the pump for the first time. 2.
2.13 iMeter Calibration All iMeters are tested, calibrated and sealed at the factory before a dispenser is shipped. Local codes and regulations may require verification of meter accuracy at Start-up. If verification or calibration is required, sufficient product must be run through each meter to thoroughly flush out all air and completely fill the system prior to the calibration process. Each iMeter module contains two meters. The Intelligent pulser contains two sets of sensors, one set for each meter.
Figure 2-6 iMeter Module. The Intelligent Pulser has two calibration doors - one for each meter. Only one door may be opened at one time during meter calibration. 15 March 2003 Part No.
2.14 Balance Vapor Recovery System Installation Requirements 2.14.1 Dynamic Back Pressure Testing At initial installation, balance vapor recovery dispensers should have a dynamic back pressure test performed at each nozzle to ensure there are no blockages in the vapor recovery system. The dispenser should be connected to the underground and the hanging hardware (hoses, nozzles, breakaways, etc.) should be installed.
2.14 Balance Vapor Recovery System Installation Requirements, continued 6. If back pressure readings are very low (less than .02 @ 20 CFH; 0.18 @ 60 CFH; 0.4 @ 100 CFH): 1. Check test fixture for tight seal at nozzle entry point. 2. Check bellows and face seal for tears. 3. Check vapor piping for leaks. 7. If back pressure readings are high: 1. 2. 3. 4. 5. 6.
