SAFETY
SAFETY
WARNING
• 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 (pre-set) or 115 V,
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 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 pump to be exposed to freezing temperatures. This can crack the
cast iron and void the warranty.

SAFETY
ADDITIONAL SAFETY PRECAUTIONS
1. Know the pump applications, limitations, and potential hazards.
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 system before servicing any component (drain all
water from the system).
5. Secure discharge line before starting 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 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
PREPARATION
Before beginning assembly of 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 Assembly 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
Accessories Required for Assembly (not included):
DETERMINING THE DEPTH OF WELL
Using a weight tied to as 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.

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.
INSTALLATION PREPARATION
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.

INSTALLATION INSTRUCTIONS
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.
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.
Before 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.
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).

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.
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.

INSTALLATION INSTRUCTIONS
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
trapping in the pipe).
Wrap thread tape around the
threads of a male PVC adaptor
(not included). Thread the
adaptor into the front of the
pump (A).
Wrap thread tape (not included)
around threads of a 1" (2.5 cm)
discharge tee (not included).
Using a pipe wrench, thread the
1" (2.5 cm) discharge tee into
top of the pump.
