INSTALLATION
Pump Location
4. Lower the foot valve end of the piping assembly into the well.
5. Install the well seal and a well vent tube.
• Ensure the foot valve is suspended 4 ft from the well bottom.
• The 1¼-inch pipe should extend 1 foot (30 cm) above the seal.
• The 1-inch pipe should extend 10 inches (25 cm) above the seal.
6. Attach a 1¼-inch 90° elbow to the end of each pipe.
Pump Location
• Install the pump indoors in a clean, dry, and ventilated location shielded from direct sun and precip-
itation.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding, and
equipment drainage.
• Bolt unit down evenly on a good foundation, preferably concrete, to prevent unnecessary stresses
from pump movement.
• Install as close as possible to water source to minimize suction piping length.
• Keep motor-operating area as dry as possible.
Piping Connections
Risk of bodily injury, property damage, or damage to system by pressurized
fluids.
• Do not install this product if incoming water pressure is greater than 75 psi. Serious damage to plumbing can
occur.
• A pressure relief valve (not included) rated to handle full pump flow at 75 psi should be installed in the system to
prevent personal injury or property damage.
Risk of damage to pump or other equipment.
• Do not apply power to the system until the pump is primed. Do not run the pump dry, which can cause overheat-
ing and damage the impeller and seals. This will void the warranty.
• Do not use open-style wrenches to loosen plugs. Plugs may become damaged and difficult to remove.
1.
If included or desired, install a pressure gauge into the ¼-inch NPT hole on the front of the casing,
directly beside the discharge opening.
IMPORTANT: For driven wells, have an electrician replace the pressure switch with a low pressure
cut-off.
2. Attach a 1¼-inch male PVC adapter to the top hole in pump casing.
IMPORTANT: Do not over-tighten.
3. Install piping between the pump and the well piping.
4. Turn off the main water supply and the power at the main breaker.
5. Open a nearby faucet until the water pressure in the system is released.
