Wiring the Pump
IMPORTANT: Employ an electrician to do the wiring.
1.
Use a separate circuit from the distribution panel
with properly sized protection to power the pump.
2. Install a properly fused disconnect switch in the line.
• Use the correct gauge of cable to carry the load.
IMPORTANT: Undersized wire between the motor
and the power source will adversely limit the start-
ing and load-carrying abilities of the motor.
3. Wire the connections.
• Connect the power lines to the pressure switch terminals marked L1 and L2.
• Very long leads will require a larger cable.
• Ensure the pump and motor is grounded to the ground in the distribution panel or to the well
casing, if metal.
IMPORTANT: For driven wells, water levels may be too low to pump at times. Employ an electri-
cian to replace the pressure switch with a low pressure cut-off switch to prevent pump damage.
Physical Installation
Well Installation
1.
Place the red rubber gasket over the venturi.
• Make sure the hole sizes match.
2. Attach the injector assembly to the front of the pump casing, using the provided washers and
bolts.
• Be sure the "bottom" label is at the bottom of the pump.
NOTE: Any extra venturis and nozzles in the injector kit are not needed for this application.
Driven Wells
1.
Drive the well point into the ground.
• Refer to the well point manufacturer's instructions.
• Ensure the well point is deep enough to bore through the water bearing formation below the
water table but does not exceed 25 feet of depth.
• If an individual well point does not supply enough water, consider a multi-point installation.
2. Install enough piping to reach the water source and leave 1 foot (30 cm) of protruding pipe.
• The rise pipe should be galvanized in approximately 5 feet (1.5 m) sections.
3. Attach a 1¼-inch 90° elbow to the end of each pipe.
4. Attach a 1¼-inch check valve to the 1¼-inch galvanized nipple.
5. Attach a 1¼-inch male PVC adapter to the 1¼-inch check valve.
Drilled Wells
1.
Find the total length needed for 1¼-inch PVC pipe and coupling(s).
• Measure the distance from the top to bottom of the well and subtract 5 feet.
2. Assemble the foot valve, 1¼-inch male PVC adapter, and well piping.
IMPORTANT: Remove any burrs or shavings from cutting the pipes.
3. Firmly clamp the unfinished pipe end with a pipe clamp 1 foot (30 cm) from the top of the pipe.
