1 Selection Selection Information General The Racor Marine Diesel Spin--on Series feature a variety of compact sizes to fit most installations and cramped engine compartments. Mounting Heads: These units feature multiple fuel ports and many have more than one inlet or outlet. All have a unitized mounting bracket. The and Series heads feature a built--in, hand operated fuel priming pump to simplify servicing procedures. Filters: All units feature spin--on replaceable filters and contaminant collection bowls except for the high--pressure A. All units may be specified with an in--bowl water probe when used with diesel or kerosene applications. High--capacity Aquabloc t filter elements stop water and remove solid contamination. A micron filter (or secondary and even final) is used to filter fuel which is known to be of good quality. A micron filter, used with the R model, (or final filter) is the finest filtration available and is the last filter used prior to engine ingestion. A simple rule to remember is the finer the filtration, the more frequent the filter change. (Carry extra filters on board). Reusable Collection Bowls: The metal bowls used with these models feature an NPT tapered thread plug for removing contaminants. An optional UL. Listed shut--off drain valve may be ordered to simplify servicing. Options --Available for Diesel fuel systems only. Water Probe RK9. When used with a Racor Water Detection Module, the operator can be alerted of a high--water condition, even while the equipment is operating. The bowl is then drained of water at the earliest convenience. Note: A Racor Water Detection Module is needed to work with this probe. See Accessories. Water Probe RK. Same features as above, except the or vdc electronic detection module is built--in the probe housing. Includes a detachable connector. See Accessories. Danger! Do not use water probes with gasoline applications. This could cause an explosion. SELECTION. Along with the information you obtained in SECTION, SELECTION (page 9), consider the following: Are there any space limitations in the available location? The location should provide adequate space for removing the element, draining off contaminants from the bowl (and operating the primer pump on and Series models).. What filtration rating is needed?, or micron?. What options are needed? Water probe and/or a bowl shut--off drain valve? Using this information, select a unit from the next page, or check the models which follow to find the right unit for your application.
