TM 10-4330-237-13&P CHAPTER 1 INTRODUCTION Section I. GENERAL INFORMATION 1.1 SCOPE. Type of Manual: Operator's, Unit Level, and Direct Support Maintenance Model Number and Name: Advanced Aviation Forward Area Refueling System (AAFARS) Filter- Separator, Water, Liquid Fuel, P/N 13230E5875. Purpose of Equipment: To provide filtered fuel at a maximum flow rate of 240 gpm. 1.2 MAINTENANCE FORMS AND PROCEDURES. Department of the Army forms and procedures used for equipment maintenance will be those prescribed by DA Pam 738- 750 as contained in Maintenance Management Update. 1.3 CORROSION PREVENTION AND CONTROL. Corrosion Prevention and Control (CPC) of Army material is a continuing concern. It is important that any corrosion problem with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in future items. While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem. If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality Deficiency Report. Use of keywords such as "corrosion", "rust", "deterioration", or "cracking" will ensure that the information is identified as a CPC problem. The form should be submitted to the address specified in DA Pam 738-750. 1.4 SAFETY, CARE AND HANDLING. The AAFARS liquid fuel filter-separator may be used to filter various fuels. It must be assumed that residual fuel and fuel vapors are present in the liquid fuel filter-separator at all times, even after draining or purging. Therefore the equipment must always be handled with the same degree of caution as actual fuel. One or more fully charged fire extinguishers must be present at all times, not only during operation. In addition, fuels may contain toxic additives. Rubber gloves should always be worn when handling components which are in regular contact with fuel. A static electric charge is always present in all fuels. The charge increases when the fuel is being pumped, stirred, shook, or splashed. Any physical movement of the fuel will increase the static charge. If the charge is allowed to build sufficiently it will discharge, causing a spark which will ignite fuel vapors. The build up of static electric charge is controlled by bonding and grounding of all fuel handling equipment. A grounding cable assembly is provided with the liquid fuel filter-separator and must be inspected, maintained and used consistently and conscientiously to prevent fuel ignition due to electrostatic discharge. Fuels are dangerous under all conditions. Always observe fuel handling safety precautions. 1-1
