OPERATION
Physical Installation
4. Install a pressure relief valve near the discharge rated to handle pump flow at 75 psi.
5. Install a pressure gauge into the 1/8" NPT hole on the front of the casing, opposite the pressure
switch.
6. For systems with a tank, make sure the pre-charge pressure of the tank is 28 psi.
7. Add unions and valves to allow system service without disabling the complete water supply.
• If the distance from the well to the pump is more than 40 feet, install a check valve close to the
pump, in addition to the foot valve.
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.
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 and then shut it off.
10. Repeat steps 2 - 9 for every 5 feet (1.5 m) of suction line until the water is pumping continuously.
• For systems with an in-line check valve, priming will need to 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.
