DETAILED INSTALLATION INSTRUCTIONS
s WARNING
!
DO NOT RUN THE PUMP BEFORE PRIMING IT; THE SEAL AND IMPELLER COULD BE PERMANENTLY DAMAGED
Before proceeding, ensure power has been shut o at the breaker. If this is replacing an existing pump, completely relieve pressure from the water system
before working on the water system. Open the faucet nearest the tank and allow the water to drain until the tank is empty.
SHALLOW WELL APPLICATION
(for pumping depths down to 25 ft [7.6 m])
Shallow well installations use only a single pipe connecting the pump to
the water supply. This pump can be used for drilled wells (see Figures 3,
4 or 6) or driven wells (see Figure 5). Drilled wells are holes drilled into
the ground by professional well drillers using a large rig. Driven wells use
a well point (also known as a sand point), which is a long pointed tube
with a screen that allows water to enter the pipe but keeps out sand and
sediment. The water level in a driven well is fairly high or near ground
level (maximum 30 ft [9.1 m]). Continue with the appropriate shallow
well installation.
DRILLED WELLS (with foot valve)
1. Measure from the bottom of the well to the top of the well and
subtract 5 ft (1.5 m). This is the length of 1-1/4" rigid PVC pipe
and couplings you will need from the bottom of the well to the
first elbow. Cut the pipe and use a round file to smooth the pipe
cutting. Ensure the pipe is clean and free of any pipe shavings
or pieces, as these could get into the pump and damage the
impeller. The remainder of the pipe will be used to connect the
pump to the well.
2. Attach the 1-1/4" male PVC adapter to one end of the rigid PVC
pipe and attach the adapter to the foot valve. Check to ensure the
joints are airtight. Even a pinhole can prevent proper operation
of the pump.
3. Firmly clamp the unfinished end of the pipe with a pipe clamp
1 ft (30 cm) from the top of the pipe. This will prevent the pipe
from dropping to the bottom of the well. Lower this section into
the well foot valve-first.
4. On the end protruding from the well, which is held in place with
the pipe clamp, insert the well seal and have the pipe protrude
1 ft (30 cm) outside of the well seal. If you have measured
correctly, the foot valve will be suspended 4 ft (1.2 m) from the
bottom of the well. This will ensure that sand and sediment
doesn’t get drawn into the system. Install a well vent tube
in the well cap.
5. Attach the end of the pipe securely to a 1-1/4" PVC 90° elbow.
6. Install the pump in a clean, dry, and ventilated location that
provides adequate room for services and protection from freezing
temperatures. The pump should be bolted to a good foundation,
preferably concrete, and provided with adequate drainage.
Locating the pump as close as possible to the water source
reduces the friction in the suction pipe and will provide
maximum performance.
7. A pressure gauge is not supplied with the pump. It should be
installed into the 1/8" NPT hole on the front of the casing on the
opposite side of the pressure switch (see Typical Installations,
Figures 3, 4 or 6).
8. Attach a 1-1/4" male galvanized adapter into the suction inlet.
Do not overtighten, as this could crack the fitting.
9. Use the remainder of the PVC pipe from Step 4. Smooth the pipe
cutting using a round file. Ensure the pipe is clean and free of any
pipe shavings or pieces, as these could get into the pump and
damage the impeller. Connect one end of the pipe to the adapter
attached to the suction inlet. Check thoroughly for any leaks.
All connections and joints must be airtight. A small pinhole leak
can prevent the pump from operating properly.
10. Follow the Pump to Tank Installation procedures.
11. Verify everything has been completed using the Installation
Checklist provided in this manual.
