Equipment specifications for this project are based on microprocessor-based fuel day tanks specification. 1.4 SUBMITTALS A. Shop drawings: 1. Outline drawings of assembly. 2. One line diagrams and wiring diagrams for assembly and components. B. Product data: 1. Technical data on all major components. C. Project information: 1. Test reports and certifications. 2. Factory test procedures. 1.5 QUALIFICATIONS The fuel day tank manufacturer shall be certified to ISO 9001 International Quality Standard and shall have third party certification verifying quality assurance in design/development, production, installation and service, in accordance with ISO 9001. The manufacturer of this equipment shall have produced similar equipment for a minimum period of ten years. When requested by the engineer, an acceptable list of installations with similar equipment shall be provided, demonstrating compliance with this requirement. Production pressure test shall be performed by the manufacturer on each tank prior to shipping in accordance with prevailing standards of UL-142 and CAN/ULC-S601-07. These tests are intended to verify compliance with production requirements of the standard for leakage. The test is to be conducted before painting the tank by applying an internal air pressure and using soap suds, or equivalent material, for the detection of leaks. For a horizontal or rectangular tank, the test gauge pressure is to be not less than 3 psi (21 kPa). If a leak should be detected during production testing, the leak shall be repaired. Tanks shall be retested until zero leaks are apparent during two (2) successive test periods. A record of the manufacturer's testing shall be permanently maintained and available to the end user or customer. The installing contractor must have a minimum of five (5) years' experience in the design, installation and testing of fuel day tank systems. A list of systems of a similar nature and scope shall be provided on request. The installing contractor shall test the system during start-up to assure the overflow line transfers an overflow through continuous piping, without valves or traps, back to the source tank or to a collection system. The installing contractor shall test the system during start-up to assure the return pump system will move fuel overflow back to the source tank or to a collection system. 1.6 WARRANTY The manufacturer shall warrant the material and workmanship of the fuel day tank for a minimum of one (1) year from date of shipment. The manufacturer of the fuel day tank(s) shall offer an extended coverage (years 2 - 5) 2.0 PRODUCTS 2.1 CAPACITY Fuel Day Tank capacity shall be based on NEC 2011, NFPA 70, Article 701.12 (B) (2) where internal combustion engines are used as the prime mover, an on-site fuel supply shall be provided with an on premise fuel supply sufficient for not less than two (2) hours of full-demand operation of the system. The day tank shall be sized in accordance with these standards and the capacity shall not be less than ___2 gallons. 2.2 CONSTRUCTION Fuel Day Tank shall be made of heavy gauge steel construction. Tank shall include removable, welded steel top cover for indoor applications, Tank shall be coated with rust inhibitor within inner tank, primed and finish painted on external tank with epoxy paint. The installing contractor shall provide schedule 40, ASTM A 53, black iron pipe connections to the day tank fittings. All connections to be made with pipe unions to facilitate tank service/removal. The tank shall include at a minimum the following fittings: o 1" NPT engine supply o 1" NPT engine return o NPT fitting for emergency vent, sized per the requirements of NFPA 30 and UL-142/ULC-S601 o 1" NPT overflow. o 2" NPT normal vent o 4 ½" square inspection port below electrical controls The tank shall be provided with atmospheric (normal) vent cap with screen and emergency pressure relief vent sized per the requirements of NFPA 30 and UL 142 / ULC S601. Emergency vent cap shall be spring-pressure operated. Opening Pressure shall be 0.5 psig; full opening pressure 2.5 psig. Flow rate shall be marked on top of each vent. 2.3 DESIGN REQUIREMENTS 2.3.1 Fuel Day Tank Control, Alarm and Status Display. The microprocessor-based electronic control module (ECM) shall be specified for control of redundant pump operation. Where power is needed for the operation of the fuel transfer pumps to deliver fuel to a generator set day tank, the pumps shall be connected to the legally required standby power system. The ECM shall receive a signal from a single electrical analog float sensor. The ECM shall be provided with the following indications: fuel level, alarm, function, and existing warning and shutdown conditions and be located within a Type 1 zinc-plated enclosure for indoor use. The lamps shall be high-intensity LED type. The lamp condition shall be clearly apparent under bright room lighting conditions.
