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.

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).

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
Air pressure in the tank must be
2 PSI lower than the “cut-in” of
the pressure switch.
Wrap all threads with thread tape. In
order for the pump (A) and the pressure
tank (not included) to operate properly,
the pressure tank needs to be drained of
all water BEFORE INSTALLING IT TO THE
PUMP. Thread a 10" (25.4 cm) tank tee
(not included) or another necessary size
tee into the pressure tank.
Plug one outlet on top of the tank tee
with a 1/4" (6.4 mm) plug (not included)
and install a pressure gauge (not
included) on the other outlet on top of
the tank tee. Thread two 1" (2.5 cm)
female PVC adaptors (not included) onto
the two inlet sides of tan tee. Thread a
1/2" (1.3 cm) relief valve and a
1/2" (1.3 cm) drain valve (both not
included) to the front of the tank tee.
10
11
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 (not
included). 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.
12 Using PVC purple primer and PVC
cement, attach a section of
1" (2.5 cm) PVC pipe (not included)
as needed to connect the 1" (2.5 cm)
male PVC adaptor on the discharge
tee to the 1" (2.5 cm) female PVC
adaptor on the tank tee. Attach
another section of 1" (2.5 cm) PVC
pipe (not included) as needed to
connect the other 1" (2.5 cm) female
PVC adaptor on the tank tee to the
water system from the house.
CAUTION! Never install a shut-off valve
between the pump (A) and the tank, as
this can cause excessive friction loss and
can damage the pressure switch and/or
pump (A). If necessary, only install a fully
open gate valve (not included).

14
To prime, remove both:
a. The plug from the top of the
discharge tee (water will be
filled in here); 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 trap 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 wrench.
NOTE: All electrical work should be
performed by a licensed electrician.

PRESSURE SWITCH INSTALLATION INSTRUCTIONS
To complete the installation, you must connect the power source to the pressure
switch. A 30/50 PSI pressure switch has been installed on the pump. The pressure
switch allows for automatic operation; the pump starts when pressure drops to the
“cut-in” setting (30 PSI pre-set).
You will need a tire gauge to test the pressure in the tank!
1. To wire the pressure switch:
2. Remove the pressure switch cover on
pump to expose the wiring terminals.
3. Connect the green ground wire of the
power supply to the switch ground
terminal.
4. 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 (ex. 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.
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.
