Product Information :

The Jabsco 31670-0092 is a dual max 7.5 GPM two stage water system with accumulator tank, 3/4 Inch Hose Ports, coupled to a 12 Volt DC Motor. The two pumps used this system are Multi-Chamber Diaphragm Pumps with Glass Filled Polypropylene construction. The system is Self-Priming and has a Suction Lift to 5 feet (1.5 m) and a flow up to 7.5 GPM (28.4 LPM). The pumps are controlled by a Pressure Switch which turns On at 20 PSI, and Turns Off at 40 PSI. The Motors on the pumps are Permanent Magnet type with Thermal Overload Protection. The Accumulator Tank on this system is Hygienic, with impact and pressure resistant Plastic Construction, and has a 33 fl. oz (1 Liter) capacity.
This is a versatile two stage system and under low demand conditions only the primary pump operates delivering up to 3.8 gpm. Amp draw is well below that of other high flow systems under the same conditions. The accumulator tank capacity is perfectly matched to the primary pump - an additional large accumulator is not required. Under high demand the secondary pump is activated. and flow increases. Under maximum demand total current draw is only 15 amps (12vdc) or 7.5 amps (24vdc). This dual pump configuration offers increased reliability and should either of the system pumps become inoperable for any reason, the remaining pump will continue to function with the capability to supply several outlets.

The Dual Max Automatic Water System is designed for boats and RVs with multiple outlet water systems. The system operates automatically. When a faucet is opened, the system instantly begins operation to provide a smooth constant flow from tank to faucet. Closing the faucet automatically discontinues system operation. The accumulator tank smooths water flow and reduces on/off cycling of the pump by lessening the variation in pressure. Even flow of water gives better control of hot water temperature especially noticeable with instantaneous gas water heaters and showers. Reduced on/off cycling reduces noise from the pump, water hammer and gives longer pump life. INSTALLATION The Dual Max system is selfpriming and may be located above or below the fresh water tank in a dry location. If the system has rigid piping, provide a short length of hose between pipe and the pump to avoid noise and vibration. Use stainless steel clamps at both ends of hose. NOTE Inlet and outlet hose must be minimum 3/4 Inch ID reinforced hose. Branch lines to outlets should be no smaller than 3/8 Inch. Two inlet strainers have been installed in the Dual Max system to keep debris out of system. Fresh water tank must be vented. If the system includes a city water inlet, an inlet pressure regulator which reduces pressure to 40 psi or less is required. The Jabsco 44410 Series is recommended. Avoid any kinks or fittings which could cause excessive restrictions. Remember to periodically clean faucet and Pumpgard screen. Each of the two pumps is supplied prewired with an automotive type fuse. These fuse/holders must remain in place to isolate the pumps from each other and allow the remaining pump to operate should one fail. ACCUMULATOR TANK PRESSURE Accumulator tank precharge air pressure should be checked annually. Turn pump circuit off. Open a faucet and relieve all system water pressure. Adjust precharge air pressure using an ordinary tire pressure gauge and tire pump. Air inlet valve is located on the end of the accumulator tank. Tank precharge pressure should be 10 psi. Close faucet and turn pump power on. Do not overpressure tank. Pressures over 125 psi may rupture tank.
