The PAR-MAX Automatic Water System Pump is designed for self-contained boats and RV’s with multiple fixture water systems. The system operates automatically. When a fixture is opened, the pump instantly begins operation to provide a smooth constant flow from tank to faucet. Closing the faucet automatically discontinues pump operation.
The PAR-MAX pumps are self-priming and may be located above or below the fresh water tank in a dry location. To vertically mount these units, it is best to do so with the motor on top. This will prevent water dripping on motor in the event of a leak. Place pump on a solid surface and secure with four mounting screws (not included) being careful not to compress the rubber grommets which act as shock absorbers.
Select two of the port adaptors supplied to match your plumbing system. Flexible potable water hose or PEX tubing is recommended instead of rigid piping at pump. If you choose to use rigid piping, provide a short length of hose between pipe and the pump to avoid noise and vibration. Use clamps at both ends of hose to prevent air leaks into the water line. NOTE: Intake hose must be minimum 1/2″ (13 mm) ID reinforced hose. Main distribution line from pump outlet should also be 1/2″ (13 mm) ID with branch and individual supply lines to outlets no smaller than 3/8″ (10 mm). A Jabsco “Pumpgard” in line strainer should be installed between pump and tank to keep debris out of pump and system. Fresh water tank must be vented. Avoid any kinks or fittings which could cause excessive restrictions. Remember to periodically clean faucet and “Pumpgard” screens.
In an easily accessible location, install a switch (Jabsco 44960-Series) to control electricity to the pump. Turn the pump off when not used for extended periods or when the tank is empty. The electrical circuit should be protected with an overcurrent protection device in the positive lead. See chart for proper size. The pump circuit should not include any
other electrical loads. The free lead at the pressure switch is positive. Black wire from the motor is negative. Select wire size from chart below. Use total length of wire from the battery to pump and return. Chart allows for 3% voltage drop. If in doubt, use next larger wire size.
