OPERATION
Priming with an In-line Check Valve
4. Install a pressure relief valve near the discharge rated to handle pump flow at 75 psi.
• Locate the relief valve near the discharge of the pump and in an area with adequate drainage.
• Orient the relief valve so that the valve will not spray toward the pump or other electrical
devises.
IMPORTANT: For well point installations, also attach a restrictive valve prior to the tank.
5. Add piping and coupling to join up to the service line.
IMPORTANT: Ensure the friction loss will never exceed 20 ft (6 m) of head.
6. For systems with a tank, make sure the pre-charge pressure of the tank is 28 psi, as this pump's pre-
charge pressure (or the pressure at which the pump will start) is 30 psi.
7. Add unions and valves to allow system service without disabling the complete water supply.
OPERATION
Risk of damage to pump or other equipment.
• Pumping sand or other abrasives can damage the pump and void the warranty.
• If pump is run dry, it may damage pump and void the warranty.
Priming with an In-line Check Valve
1. Open the discharge valve on the service line and nearby tap to monitor the water flow.
2. Remove the vent and priming plugs with a wrench.
3. Fully open the control valve.
4. Pour approximately 1 quart (1 liter) of clean water for every 3 feet (1 m) of suction line through the
priming plug opening until water flows out of the vent hole.
5. Insert and hand-tighten the vent plug.
6. Fill the pump until water flows out of the priming hole.
7. Insert and hand-tighten the priming plug.
8. Start the pump.
• If a tap is visible, you may see a short discharge of water for about 5 to 10 seconds.
9. Run the pump for 2 minutes. Shut off.
10. Repeat steps 2 - 9 for every 5 feet (1.5 m) of suction line until the water is pumping continuously.
• Priming will be repeated about 2 - 6 times.
• If the pump does not draw water within 8 tries, shut it off and check the suction line for leaks.
11. Firmly tighten the vent and priming plugs with a wrench.
Priming with a Foot Valve
1. Open the discharge valve on the service line and nearby tap to monitor the water flow.
2. Remove the vent and priming plugs with a wrench.
3. Pour approximately 1 quart (1 liter) of clean water for every 3 feet (1 m) of suction line through the
priming plug opening until water flows out of the vent hole.
NOTE: If the suction line does not fill, follow the directions for an in-line check valve.
4. Insert and hand-tighten the vent plug.
5. Fill the pump until water flows out of the priming hole.
6. Insert and hand-tighten the priming plug.
