Soil piping to the system must slope 1/4 inch per foot when the vessel is at its normal trim. This will insure adequate flow velocity and prevent deposition of sewage solids in the pipes. Bypass. Provision should be made for direct overboard discharge of sewage, bypassing the FAST system. This will provide sanitary facilities for the crew in case of malfunction, and also permit bypassing at sea where treatment is not required. The simplest method is a two valve gravity flow arrangement.-Ball valves arc fooommondod. Gate valves are acceptable so long as the stems are oriented upward to prevent clogging. When larger vent size is required, enlarge to the larger pipe size as close to the media tank as possible. **Each wfmedia tank used in the+SW-is equipped with a 3 4r'-inch vent connection. These should be combined into a single vent of the size specified in the table as close to the media tanks as possible." '// The trap should be equipped with a 2 inch cleanout and fill connection at the top of the inlet pipe, and a 2 inch cleanout at the bottom. Trap. It is necessary to isolate the vessel soil piping from the sewage system with a water seal trap. Occasionally, detergent foam will form in the media tank and partially block the media tank vent, creating backpressure. The trap will prevent this backpressure from affecting operation of the toilets. The minimum depth of the trap shall be not less than sixteen (16) inches, from the centerline of the outlet pipe to the centerline of the pipe at the bottom of the trap. Note that the inlet to the trap is 1 -0" or more above the outlet. This 1 '-O" drop corresponds to the expected worst case backpressure in the media tank vent.4f.4 :-Q".drop4cnot available, Trap Vent. The upstream side of the trap should be equipped with a 2 inch vent to the exterior of the vessel. This will permit free flow of sewage in the soil pipes.4f the soil fees.are-adequatoly vented to atmosphere,'this vent may.not. be required. However, if the fixtures incorporate one way (check valve) air inlets, a separate trap vent will be required. The trap vent may be fabricated from ordinary black iron pipe. ^SHEET NO. 66 Media Tank Vent. The media tank must be vented to the exterior of the vessel, and this vent must not be combined with the trap vent or any other soil line vent upstream of the trap. The media tank vent should be fabricated from galvanized steel pipe or other material suitably protected against corrosion.)(a flame screen is required (for inspected vessels only), the exterior termination of the vent should be fitted with a EXXON BOSTON SEPT. 19F8 EXX-MOR-010731 3 pipe reducer, so that the opening and flame screen will be two pipe sizes larger than the vent pipe size. This will reduce the additional pressure drop due to the screen. The exterior termination of the vent should be located to permit removal and cleaning of the screen. See Table 1 for minimum tank vent size. Air Piping. Air piping from blower to media tank must be one (1) inch pipe size. Acceptable Vent Piping (General). Vents must terminate not less than 10 feet from any ventilation air inlet, window used for ventilation, doorway normally used by personnel, or source of vapor ignition. Vent piping must slope not less than 1 inch per foot upward and away from the media tank or trap so that condensation will not accumulate in the vent. Vent runs should be as short as practicable. For inspected vessels, the U. S. Coast Guard requires a flame screen on all vents. Water Piping. Pump discharge piping should be 1-1/4 inch and all other water piping shall be 2 inch pipe size. The 2 inch pump suction piping should be reduced to 1-1/2 inch at the pump suction connection. If media tank and wet well are set at the same deck level, maximum length of the spillover line from media tank to chlorinator to wet well is 30 feet. Piping should slope downward from the media tank at 1 /4 inch per foot. The run between the media tank outlet and chlorinator inlet must be equipped with a trap with centerline to centerline depth of sixteen (16) inches. No drop is needed. Inlet and outlet of the trap can be at the same level. Media Tank. The media tank may be installed on a flat deck or on two longitudinal or three transverse frames with bearing areas at least 3 inches wide. The frames should pick up the six bolt holes predrilled on the tank baseplate. The tank may be secured in place with six 1/2 inch grade 5 bolts, or with ifrroo,.3 inoh long 3/6 ffl-oh ftitetwoldC'Opaood ateog caoh long-eidc-of ae.baseplate. The tank baseplate should be horizontal when the vessel is at its normal trim. Provide at least 2 -0" above the top of the tank for access. Tablet Chlorinator. The tablet chlorinator is preassembled to a bracket for bulkhead mounting. It should be installed so that the notches in its bottom are at the downstream end. Tilt the bracket or shim the chlorinator so that it slopes 1 /4 inch per foot (centerline of outlet connection about 1/2 inch below centerline of inlet connection). Be sure the tilt angle is such that water does not accumulate in the bottom of the chlorinator. The chlorinator may be located at any point in the line between media tank and wet well, but must be downstream of the trap and not less than 2 -8" above the base of the wet well. Provide at least 1 -O" access above the top of the feed tubes for their removal. Note: in both water and air piping use unions to permit removal and maintenance of components. SHEET NO. 67 Wet Well. The wet well may be installed on a flat deck or on two frames with bearing areas at least 3 inches wide. The frames should pick up the four bolt holes predrilled on the tank baseplate. Secure with either four 112 inch grade 5 bolts - or with two 3 inch long 3/16 inch fillet welds on each side. The tank baseplate should be horizontal when the vessel is at its normal trim. EXXON BOSTON SEPT. 1078 EXX-MOR-010732 4 Allow at least 1 '-6" above the top of the tank for access. Discharge Pump. The discharge pump should be operated in the flooded suction mode. Its base should be not more than 2 -0" above the baseplate of the wet well. If the discharge head is greater than 15 feet or if the discharge point may be submerged, install a check valve in the discharge line. The pump base should be tack welded to the deck. Do not run the pump dry! If the pump is run backward, the rotor may unscrew and the pump will not deliver water. If this happens, disassemble the pump and reassemble the rotor and pump. Electrical Equipment. Motors and the pump starter control transformer can be connected for either 220/230 VAC or 440/460 VAC operation. (These motors are not suitable for 208 VAC operation. If 208 VAC operation is required, special motors are required.) Unless otherwise stated in the purchase order, the overload heater coils furnished will be for 440/460 VAC. Table 3 lists proper Cutler-Hammer part numbers. Table 3. Overload Heater Coil Part Numbers Line Voltaqe Blower Starter Pump Starter Blower. The blower assembly is preassembled to a bracket for bulkhead mounting. Install so that the silencer inlet will not pick up foreign objects from the deck, and with belt drive towards the bulkhead. Make sure that the blower gear case has oil in it before starting. The fill plug is at the top of the gear case (opposite the drive end), the oil level plug is below it and just above the drain plug. Add SAE 40HD oil until it overflows from the oil level plug hole. See Table 2 for standard sheave sizes. Table 2. M Series Sheave Sizes FAST Model No. Motor Sheave Blower Sheave The pump starter incorporates a line disconnect which can break all current to both motors. It should be located in sight of the motors. The pump starter also incorporates a fused control transformer to produce 110 VAC for the pump pilot circuit. 2 6* 14.6 M.I I Blower Relief Valve. The-roliof-valvo should bo The purpose of the relief valve is to protect the blower from damage due to overpressure. Make sure that the relief valve operates freely and is lubricated with machine oil. Electrical service required is 3.5 KVA. The branch circuit feeding the motor starters should be protected by a 20 amp circuit breaker. Cables should be bronze armored marine type, TTIB-4 and DTIB-4 as applicable. Junction boxes should be watertight, and cables should enter starter enclosures at the bottom. In running cables and locating cable supports do not weld on body of media tank or wet well. The liquid level switch on the wet well incorporates 3 independent sets of contacts: pump off (2 red wires), pump on (2 yellow wires) and high level (2 blue wires).
