SAFETY
SAFETY
• This pump is meant to be used where the vertical lift of water is less than 25' (7.6 m). If the
well is deeper than that, you need to purchase a deep well convertible jet pump.
• Do not pump flammable or explosive liquids such as oil, gasoline, kerosene, ethanol, etc. Do
not use in the presence of flammable or explosive vapours. Using this pump with or near
flammable liquids can cause an explosion or fire, resulting in property damage, serious
personal injury and/or death.
• Always disconnect the pump from its power source before inspection.
• Do not touch the pump housing while it is operating as the pump may be HOT and can cause
serious skin burns.
• Do not disassemble the motor housing. This pump has NO repairable internal parts, and
disassembling may cause leakage or dangerous electrical wiring issues.
CAUTION:
• The motor MUST NOT be started before the pump is primed!
• This is a dual voltage motor. It can be wired for 230 V or 115 V (pre-set), depending on the
power source.
• This pump is equipped with a 30/50 PSI pressure switch. If the previous pump used a
different switch, you must reset the tank to 28 PSI. An air compressor may be needed to
do this.
• In order for the pump and tank to operate properly, the tank needs to be drained of all
water and set to the proper pressure level BEFORE startup.
• For safety, the pump motor has a resetting thermal protector that automatically will turn
off the pump if it becomes too hot. Overuse of this feature will damage the pump and void
the warranty.
• Once the thermal protector detects that the pump has cooled to a safe temperature, it will
allow the pump to operate normally. If the pump is plugged in, it may restart unexpectedly.
• Do not allow the pump to be exposed to freezing temperatures. This can crack the cast
iron and void the warranty.

2. Make certain the electrical power source is adequate for the requirements of the pump.
3. ALWAYS disconnect the power to the pump before servicing.
4. Release all pressure within the system before servicing any component (drain all water from
the system).
5. Secure the discharge line before starting the pump. An unsecured discharge line could whip,
possibly causing personal injury and/or property damage.
6. Secure the pump on a solid base.
7. Check that all pipe connections are tight to minimize leaks.
8. Make certain the electrical circuit to the pump is protected by a dedicated 15 A or larger fuse
or circuit breaker.
9. Never use extension cords with this pump!
10. Do not handle pump or pump motor with wet hands or when standing on a wet or damp
surface, or in water.
11. Wear safety glasses at all times when working with pumps.
12. Follow all electrical and safety codes, particularly the National Electrical Code (NEC) or the
Canadian Electrical Code (CEC), and in the workplace, the Occupational Safety and Health Act
(OSHA) or the Canadian Centre for Occupational Health and Safety (CCOHS).
13. This unit is designed only for use on 115 V or 230 V, 60 Hz. Directly connect pump wires into
properly grounded circuit board in accordance with the NEC or CEC and local codes and
ordinances. All wiring should be performed by a qualified electrician.
14. Protect the electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking
the cord. Do not use damaged or worn cords. Failure to properly wire this pump is dangerous
and will void the warranty.

INSTALLATION PREPARATION
INSTALLATION PREPARATION
Before beginning assembly of the product, make sure all parts are present. If any part is missing or
damaged, do not attempt to assemble the product. Contact customer service for replacement parts.
Estimated Installation Time (new installation): 30–60 minutes
Tools Required for Assembly (not included): Wrench, Pliers, Cross-head Screwdriver, Thread Tape,
PVC Purple Primer, and PVC Cement
DETERMINING THE DEPTH OF WELL
Using a weight tied to a string, determine the depth of the well by dropping the weight down the
well, and then:
• Measure the ground level mark to where the string is wet. This is your well's water level.
• This number must be 10' (3 m) under the pump's normal pumping level.
• Subtract 5' (1.5 m) from this measured water level number. This number must be less than
25' (7.6 m).
• See Step 3 of Installation Instructions for a diagram.
Accessories Required for Assembly (not included):
1 1/4" (3.2 cm) and 1" (2.5 cm) PVC adaptors
1 1/4" (3.2 cm) and 1" (2.5 cm) PVC pipes
1" (2.5 cm) sealing gasket
Relief valve
Drain valve
1" (2.5 cm) MNPT x 1 1/4" (3.2 cm) SLIP PVC adaptor
1 1/4" (3.2 cm) single drop well seal
1" (2.5 cm) flexible joint
1 1/4" (3.2 cm) foot valve

LOCATION OF THE PUMP
Decide on the area for the pump installation. Select a pump location with adequate space for
future pump maintenance. It can be located in the basement or utility room of the house, at the
well, or between the house and the well. If installed outside of the house, it should be protected
by a pump house with auxiliary heat to prevent possible freezing. The well also should be
protected for sanitary reasons. Mount the pump as close to the well as possible.
TANKS — PRE-CHARGED STORAGE
For best performance of the pump, it is recommended that you use a diaphragm pressure tank
(not included). It is best to have this in place before installing the pump. A pre-charged storage
tank has a flexible bladder or diaphragm that acts as a barrier between the compressed air and
water. This barrier prevents the air from being absorbed into the water and allows the water to
be acted on by compressed air at initially higher than atmospheric pressures (pre-charged).
More usable water is provided than with a conventional type tank. Pre-charged tanks are
specified in terms of a conventional tank. For example, a 20-gallon pre-charged tank will have
the same usable water or draw-down capacity as a 40-gallon conventional tank, but the tank is
smaller in size.
CAUTION:
In order for the pump and tank to operate properly, the pressure tank needs to be drained
of all water BEFORE INSTALLING THE NEW PUMP. After draining, if you are using the
supplied 30/50 PSI pressure switch at the pre-set settings, add or adjust the air pressure
in the tank to 28 PSI of pressure BEFORE startup.

NOTE: Use a minimum of 1 1/4" (3.2 cm) diameter PVC piping for the suction pipe for best performance.
A 1" (2.5 cm) MNPT x 1 1/4" (3.2 cm) SLIP adaptor will be needed to make the connection to the pump.
SHALLOW WELL INSTALLATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
WARNING:
All joints and connections must be AIRTIGHT. A single leak will prevent the proper operation
of the pump. Wrap thread tape clockwise on all threaded connections. For all non-threaded
connections, you must use PVC purple primer and PVC cement to ensure airtight seals.
Measure all pipe lengths before attaching.

3Before sliding the pipe assembly into the
well, firmly clamp the assembly with a pipe
clamp (not included) to prevent the assembly
from sliding down into the well.
Subtract 5' (1.5 m) from the depth of the
well. This is the total length of PVC pipe and
adaptors needed. Using PVC purple primer
and PVC cement (not included), attach as
many couplings and sections of rigid PVC
pipe (not included) to the adaptor as
necessary.
Wrap thread tape (not included) around
threads of a 1 1/4" (3.2 cm) male PVC
adaptor (not included). Thread adaptor into a
1 1/4" (3.2 cm) foot valve. Hand tighten, then
tighten 1/2 turn with a pipe wrench.
Remove pipe clamp and slide a well seal
(not included) over the PVC pipe and onto
the well casing (not pictured). The PVC pipe
should extend approximately 12" (30 cm)
from the well seal, depending on the height
of the pump (A).
NOTE: DO NOT let the assembly slide down
into well. Tighten the well seal until the
rubber gaskets are tight against the well
casing and the PVC pipe.

6Wrap thread tape around the threads
of a male PVC adaptor (not included).
Thread the adaptor into the front of
the pump (A).
8Wrap thread tape around the threads
of a 1" (2.5 cm) adaptor, thread it
onto the tee.
Using PVC purple primer and PVC
cement, attach a 1 1/4" (3.2 cm) PVC
elbow (not included) onto the rigid PVC
pipe extending from the well seal.
Using PVC purple primer and PVC
cement, attach as many sections of
rigid PVC pipe and couplings (not
included) as needed to connect the
male PVC adaptor to the PVC elbow.
Ensure the pipe slopes slightly toward
the well (to prevent air from being
trapped in the pipe).
9Spread the PVC cement on the outer
screw of the adaptor and inner screw
of the adjustable adaptor. Install the
1" (2.5 cm) adjustable adaptor into the
water system and seal with gasket.

12 This pump is pre-wired at 115 V. If the power
source is 230 V, remove the electrical
housing cover. Flip the switch to 230 V.
Replace the cover.
NOTE: All electrical work should be
performed by a licensed electrician.
11 To prime, remove both:
a. The plug from the top of the discharge
tee (fill pump and piping through
priming tee); and
b. The priming plug in front of the
discharge tee (this is to allow air to
vent out while priming).
Fill the discharge tee with water until
water overflows.
NOTE: It may take several minutes or
more to fill the pipes and the pump (A)
completely. Watch the water level in the
discharge tee. Make sure the water level
is stable and there are no air bubbles.
WARNING: If the pump is lower than the
suction pipe, air may get trapped in the
pipe. The pump may not work properly.
Make sure the pipe slopes away from the
pump.
Wrap the discharge tee plug and priming
plug threads with thread tape and
re-attach to the pump (A). Tighten with a
wrench.
Air pressure in the tank must be 2 PSI lower than the "cut-in" of the pressure switch.
NOTE: The pump (A) has a 30/50 PSI pressure switch, which means the "cut-in" is 30 PSI;
therefore, the tank needs to be set to 28 PSI. To check the pressure in the tank, use a tire
pressure gauge. If more air is needed, add air to the tank with a tire pump or air compressor.
If less is needed, bleed out some air.

INSTALLATION INSTRUCTIONS
PRESSURE SWITCH INSTALLATION INSTRUCTIONS
To complete the installation, you must connect the power source to the pressure switch. The
pressure switch allows for automatic operation; the pump starts when pressure drops to the
“cut-in” setting (30 PSI pre-set).
To wire the pressure switch:
• Remove the pressure switch cover on
pump to expose the wiring terminals.
• Connect the green ground wire of the
power supply to the switch ground
terminal.
• Connect the power supply wires to the
two outside terminals marked “LINE”
and replace the switch cover.
If you had a different pressure switch on the old pump (e.g., 20/40 PSI), make sure to adjust the
pressure in your tank to 28 PSI. You may need an air compressor to add air pressure. If you have
too much air pressure in the tank, simply press the air stem down to release air.
You will need a tire gauge to test the pressure in the tank.
WARNING:
• Before wiring the pressure switch, turn off the power source to which you are connecting
to avoid potentially life-threatening electric shock.
• It is recommended all electrical work be performed by a licensed electrician.
• When wiring from the power source to the pressure switch, it is recommended that you
use either a 14-gauge or 12-gauge cord.
Note: The ground connection must be made at this terminal. The ground conductor must not be
smaller than the circuit conductors supplying the motor.
