TM 10-4320-303-13Figure 2-17. TWDS Water Source Connection Components Assembly.NOTETo prevent leakage, make sure coupling pipe fitting is tightly fitted to couplinghalf.Suction hose lengths, coupling pipe fitting, coupling half, and Y connectionreducer are packed in crate marked 10-MILE SEGMENT.Wrap antiseize tape in direction of threads.i. Wrap antiseize tape (item 9, appendix E) around threads on 6 inch coupling pipe fitting (Figure 2-17,3). Screw 6 inch coupling pipe fitting (3) into 6 inch coupling half (4).j. Install 6 inch coupling pipe fitting (3) (with attached 6 inch coupling half (4)) on end of 6 inch butterflyvalve (1) on suction port of 600 gpm pumping assembly using grooved-end pipe quick disconnectcoupling clamp (2), unpacked from "PUMP STATION" crate, (para 2.3.3.2).k. Locate 6 inch x 10 foot lengths of rigid-walled, wire reinforced suction hose assemblies (5) with quick-disconnect fittings.l. Push cam arms on 6 inch coupling half (4) forward to open position.CAUTIONTo prevent leakage, close both cam arms at the same time. Do not strike camarms to close. Damage to couplings could result.m. Connect suction hose (5) to 6 inch coupling half (4). Close cam arms.n. Install additional 6 inch suction hose assembly lengths (5), as required, until lead pumping station canbe connected to water source.o. Push cam arms on last suction hose (5) forward to open position.2-43
