MAY CAUSE SERI-
OUS BODILY INJURY,
DEATH AND/OR
PROPERTY DAMAGE
AM) Before installing
or servicing your pump,
BE CERTAIN THE PUMP POWER
SOURCE IS TURNED OFF AND DIS-
CONNECTED.
A 2) All installation and electrical wir-
ing must adhere to state and local codes.
Check with appropriate community agen-
cies, or contact your local electrical and
pump professionals for help.
A 3) CALL AN ELECTRICIAN WHEN
IN DOUBT. Pump must be connected to
a separate electrical circuit directly from
the entrance box. Have the electrical
outlet checked by an electrician to make
sure it is properly grounded. There must
be an appropriately sized fuse or circuit
breaker in this line. Tying into existing
circuits may cause circuit overloading,
blown fuses, tripped circuit breakers, or
a burned up motor.
A 4) Do not connect pump to a power
supply until the pump is grounded. For
maximum safety, a ground fault interrupter
should be used. CAUTION: FAILURE
TO GROUND THIS UNIT PROPERLY
MAY RESULT IN SEVERE ELECTRI-
CAL SHOCK.
A 5) WARNING: Reduced risk of elec-
tric shock during operation of this pump
requires the provision of acceptable
grounding:
a) If the means of connection to the
supply-connection box is other than
grounded metal conduit, ground the
pump back to the service by connecting
a copper conductor, at least the size of
the circuit conductors supplying the
pump, to the grounding screw provided
within the wiring compartment.
b) This pump is provided with a means
for grounding. To reduce the risk of elec-
tric shock from contact with adjacent
metal parts, bond supply box to the pump-
motor-grounding means and to all metal
parts accessibie at the well head, includ-
ing metal discharge pipes, metal well cas-
ing, and the like, by means of

cause death
(1) An equipment-grounding conduc-
tor at least the size of the well cable con-
ductors, or the equivalent, that runs down
the well with the well cable and,
(2) a clamp, a weld, or both if neces-
sary, secured to the equipment ground-
ing lead, the equipment grounding termi-
nal, or the grounding conductor on the
pump housing. The equipment-ground-
ing lead, if one is provided, is the con-
ductor that has an outer surface of insu-
lation that is green with or without one or
more yellow stripes.
A 6) The voltage and phase of the
power supply must match the voltage and
phase of the pump.
A 7) Do not use an extension cord;
splices must be made with an approved
splice kit and should be checked for in-
tegrity before submerging in water, above
ground joints must be made in an ap-
proved junction box.
A8) Do not work on this pump or switch
while the power is on.
A 9) Never operate a pump with a
frayed or brittle power cord, and always
protect it from sharp objects, hot surfaces,
oil and chemicals. Avoid kinking the cord.
A 10) Never service a motor or power
cord with wet hands or while standing in
or near water or damp ground.
À 11) Do not use this pump in or near a
swimming pool, pond, lake or river.
A 12) Single phase motors are equipped
with automatic resetting thermal protec-
tors. The motor may restart unexpect-
edly causing the leads to energize or
pump to turn.
A 13) Check for nicks in the wire and
pump insulation by using an ohm meter
and checking resistance to ground before
installing the pump and after installing the
pump. If in doubt on the proper proce-
dure check with a qualified electrician.
A 14) Do not pump gasoline, chemicals,
corrosives, or flammable liquids; they
could ignite, explode, or damage the
pump, causing injury and voiding the
warranty.
15) Do not run this

vere burns. Always use a pressure relief
valve, set below the rating of the tank or
system.
A 16) Pump is capable of building pres-
sures in excess of 100 PSI. Always use
a pressure relief valve.
A 17) The well, cistern, or pit must be
sealed to prevent a child, animal or
foreign object from falling in.
À 18) While the well seal or cap is
removed for repairs, cover the well to
prevent foreign matter from entering,
contaminating the well, and possibly
damaging the pump.
À 19) Test well water for potability; chlo-
rinating the well or purifying, is recom-
mended every time the well is opened.
Check with local Health Departments for
testing and sanitizing procedures.
A 20) The following may cause severe
damage to the pump and void warranty.
It could also result in personal injury:
* Running the pump dry. This will dam-
age the pump seal. Follow priming
instructions.
* Failure to protect the pump from be-
low freezing temperatures.
* Running the pump with the discharge
completely closed.
* Pumping chemicals or corrosive
liquids.
À 21) Never work on the pump or sys-
tem without relieving the interna! pres-
sure.
A 22) Do not pump water above 120°
Fahrenheit.
A 23) Never exceed the pressure rating
of any system component.
A 24) While installing the pump, always
keep the well covered to prevent foreign
matter from falling into the well and con-
taminating the water and/or causing pos-
sible serious damage to the mechanical
operation of the pump.
A 25) After carefully removing your
pump from the carton, make a visual
inspection for any apparent shipping
damage.
O Pump Selection & Inspection
1. Select the right
pump & motor
Gallons per minute desired +
pressure required + depth to
pumping level determines which
Myers Submersible Pump size and
model is right for your water well
system.
2. Inspect your
new pump & motor
After purchase, check the pump and
motor and other contents of the
shipping container for possible
damage. Do NOT lift the Myers
submersible pump by its attached
electric motor cables.
Find the loose owner's information
plate and check the listed model
number against the label data on
the outside shells covering the
motor and the pump.
The entire pump was thoroughly
tested at the factory. However, to
make sure there is no hidden
damage caused during shipment,
we suggest checking for free
rotation of the shaft prior to installa-
tion.
1. New wells
a) Location of pump. Your Myers
submersible pump can be installed
at nearly any well location for years
and years of dependable, trouble-
free service. For new wells, always
locate well to provide for easy
removal and replacement of pump.
The water tank and electrical
controls can, of course, be located
some distance from the well.
b) Determine depth of pump in
‘well in order to purchase electrical
cables of sufficient gauge and
length to reach from pump motor to
electrical motor control box - and to
purchase galvanized iron pipe, PVC
rigid plastic pipe or flexible plastic
pipe of sufficient length to reach
from pump discharge to water tank.
(See cable length and Cable-size
charts in Sections C2 and C3.)
c) Location of water tank and
electrical controls. Always install the
О Pre-Installation Preparation
pressure tank and electrical controls
in a clean dry basement or utility
room to avoid dampness and
temperature extremes. Do not
install control box in direct sunlight.
In any installation where the pump
pressure could exceed the storage
tank pressure, provide a pressure
relief valve piped to a suitable drain.
2. Replacing pump (or
motor only) in existing well
a) Turn off power at electrical
control box.
b) Remove well seal from top of
well. |
c) Remove old pump from well.
1. If galvanized iron or rigid
plastic PVC pipe was used origi-
nally, you'll find a number of rigid
sections joined together. Pull pipe
upward and dismantle each section
as your go, untaping or unbanding
electrical motor cables from each
section until you reach pump.
2. if flexible plastic pipe was
used originally, pull pipe upward -
coiling pipe and cables in a big
circle as you go - until you reach the
pump.
3. when old pump is out of
well, cut electrical cables as close to
original splice connection as
possible.
4. while new cable is preferred
(because it will remain submerged
for a number of years), you may
wish to reuse the old cable. Wipe
off and clean the insulation, exam-
ine carefully for cuts, cracks and
abrasions. If in doubt, purchase
new cable.
5. if new cable is necessary,
measure length of old cable (from
pump motor to electrical control
box) and purchase sufficient re-
placement lengths. (See wire-size
and cable-length selection charts in
sections C2 and C3.)
@ Electrical Preparation
1. Motor voltage
Myers constant pressure controis
operate on 230 volts, single phase
current. The control changes the
voitage to 230 volt, three phase.
2. Cable Size
Submersible pump cable is not just
ordinary wire; the copper cable is
well insulated to withstand many
years of complete submersion in
water. Selection of proper size
cable is very important. Undersized
cable results in too low a voltage
supply to the motor and ultimate
motor failure. Oversized cable will
cost much more than proper-sized
cable. See chart of proper-sized
3
cable (in chart, the smaller the
AWG number, the larger the cable
wire size).
For Canadian installations: a) type
RWU, TWU, SGOW or SWOW
power supply cables are recom-
mended. b) The well seal and
motor case shall be bonded to the
main A-C ground.
3. Length of cable
Maximum cable length specified for
each horsepower size and minimum
AWG cable wire size referred to in
chart means the total distance from
the submerged pump motor to the
electrical motor control box as
shown in this diagram.
Myers warranty is void if undersized
AWG cable is used or if cable
lengths longer than specified for
each cable wire size are used.

4. Splicing power cables to pump
Aîter making sure your power cables are the proper AWG size and speci-
fied length, splice them to the pump cables (see illustrations):

WARNING! Splice and wires
should be checked for nicks and
insulation breakdown prior to
installation.
To isolate ground leakage in splice
and cable, refer to Figure 3 and
proceed as follows:
1. Set selector switch on the
highest scale (RX 100K) and follow
general instructions for ohmmeter
tests.
2. Immerse motor, pigtail, splice
and cable in tank of water with leads
out of water. If cable only is being
tested, be sure to have both ends of
the cable out of water and the ends
connected as shown in Figure 3.
3. Slowly remove cable from
water starting with the end which is
connected to the ohmmeter. Ob-
serve the needle, and when it falls
back to left toward infinity or no
reading, the damage will be at the
point where the cable, splice or
pigtail is just above the water.
4. Repair damaged cable, splice
or pigtail.
5. If the motor is grounded, it
must be replaced.
WARNING! After the pump is
installed in the well insulation
test and motor continuity test
should be run.

Make sure power is off before
performing these tests.
Insulation or ground test using
ohmmeter
To conduct the insulation or ground
test refer to Figure 2. This test is
used to determine if insulation of the
motor or cable has been damaged.
It consists of the following:
1. Set selector knob for the
highest setting (RX 100K) and follow
general instructions for ohmmeter
checks.
2. Attach one ohmmeter lead to
one motor lead.
3. Attach the other lead to an
unpainted metallic part of the motor
or pump. If the unit is in the well,
attach to the metallic drop pipe.
4. Proper resistance will be
greater than 500,000 ohms (5 on
the RX 100K scale). Less resis-
tance than this indicates excessive
ground leakage oat the splice, in the
cable insulation, or in motor winding.
Most manufacturers recommend
pulling the motor for further exami-
nation and correction of leak.
Resistances between 20,000 ohms
and 100,000 ohms do not necessar-
ily indicate a failure. But they do
indicate that a failure may occur in
the future if corrective steps are not
taken.
Motor continuity test of motor
windings and circuit
The motor continuity test, for circuit
resistance, is used to determine the
condition of the motor windings and
circuit. Refer to Figure 1 and
proceed as follows:
1. Set selector knob on the
lowest scale (RX 1) and follow
general instructions listed above.
2. Attach ohmmeter leads to two
of the three motor leads or cable
leads at a time and compare with
the chart in 3C.
3. A reading significantly higher
than manufacturers indicates a
possible burned (open) winding,
loose connection or wrong motor
(different horsepower or voltage
rating than that being checked for).
4. A considerably lower reading
than the manufacturers data
indicates a possible shorted (burned
together) winding or wrong motor
(different horsepower or voltage
rating than that being checked).
5. An unbalanced reading for a
three phase motor indicates a
burned winding or faulty connection.

Figure 2 To test insulation with ohmmeter, set selector knob for highest
setting, RX 100K. Connect one meter led to any other cable lead and the
other meter lead to ground. All three cable wires should be checked in this
test.
Figure 3 To locate leak in cable, ground one ohmmeter lead and clip the
other lead to cable wires. Gradually withdraw wire from water. When
resistance jumps to infinity, leak is just above water level.

1. Before lowering pump
a) Smooth out any rough spots
or sharp edges on the top lip of the
well casing with a hammer or metal
file to prevent damage to the pump
or power cables when lowering into
well.
b) Safety cable. To aid in
lowering pump when plastic PVC or
flexible plastic pipe is to be used or
to aid in raising the pump for future
maintenance - attach nylon or
stainless steel cable to lifting eye of
pumps.
c) The starting torque of the
pump motor tends to give a twist
which could cause the pump shell to
rub against the inside walls of the
well casing - especially if rigid PVC
or flexible plastic pipe is used. To
dampen this twisting we suggest
torque stops be used in all installa-
tions.
d) Attach an adapter to top end
of the pump and tightly band PVC or
flexible plastic pipe tot he adapter
for a tough, long-lasting fit.
e) As you add additional
sections of galvanized iron pipe or
rigid plastic PVC pipe, apply pipe
compound only to the male
threaded ends of each section and
tighten to next section.
CAUTION: Do NOT use pipe
wrench on ANY part of pump
except hex connection at top
of discharge end.

straight up from bottom to top. Do
NOT spiral cable around the pipe.
Use waterproof tape or nylon lock
bands every 5-ft on flexible plastic
pipe or every 10-ft on PVC plastic or
galvanized iron pipe. Do not allow
any excess cable between bands;
cable must be as flat against pipe
as possible.

3. Pressure Switch
The pressure switch has a
manufacturer’s setting of 50 + 2 psi
with a range of 30 psi minimum and
70 psi maximum. Adjustment to the
pressure setting can be made with a
4” Hex wrench. Turning the adjust-
ing screw clockwise will increase
the setting, while turning the adjust-
ing screw counter-clockwise will
decrease the setting.
The pressure switch is equipped
with two female non-insulated spade
terminals. 14 to 18 AWG wire can
be crimped onto these terminals.
These wires are connected to the
PS1 and PS2 switch terminal block
in the control box.
a) Align pump carefully when
beginning to lower it down the well
casing. Do not let the pump, cables
or pipe rub against the well casing.
Take care that cable insulation is not
dragged or scraped over the top lip
of the well casing.
b) Depth of pump setting.
Lower pump into well slowly without
forcing. Use foot clamp to hold
galvanized iron or plastic PVC pipe
while connecting the next length of
pipe and taping the power cables.
(On deep settings, we recom-
mend that a check valve be installed
in the pipe 200 ft. above the pump
and every 200 ft. thereafter to
prevent water shock from traveling
back to pump.)
Lower pump to at least 10 ft.
below the maximum drawdown of
the water level, if possible, and
never closer than 5 ft. from the
bottom of the well.
c) Pipe fitting to support
pump. When a well seal is used,
either a coupling, elbow or tee is

installed on the top end of the last
vertical length of pipe and is allowed
to rest on the outside of the well
seal to support the pipe, power
cables, safety cable and pump.
Most well seals provide a fitting to
seal the power cables; but if not
such fitting is provided, conduit must
be used to protect cables and to
prevent water and any foreign
matter from leaking into well around
cable.
d) Frost-proof pitless installa-
tion. In installation where the pipe
from the well seal to the water tank
is subject to frost or freezing
conditions, a pitless installation is
recommended. (See diagram on
page 7.)

@ Replacing an Existing Pump
Check and follow all local codes
and regulations prior to changing
out your pump.
a) Turn power off to the pump,
control and hot water tank. Drain
water and relieve the pressure from
the system.
b) Disconnect the power lines
at the well, disconnect the pump
from the pitiless adaptor and remove
the pump from the well.
c) Cut the power lines just
above the heat shrink connections.
Unscrew the old pump above the
check valve, and remove the old
pump.
d) Check the old wire for nicks,
if the wire appears nicked or dam-
aged use new wire, (only use
submersible approved wire). New
wire usually comes twisted, do not
straighten the wire the twisting effect
helps prevent radio interference.
e) Use an approved heat
shrink splice kit to splice the
wires. A heat gun is the best way to
heat the splices, if you use a torch
be careful not to damage the wire
insulation. The number one cause
of shorts is insulation damage due
to over heating the wire insulation
damage due to over heating the
wire insulation. (For added protec-
tion tape can be applied over the
heat shrink splice.)
f) Check the pipe for damage,
if check valves are installed, make
sure they are not sticking. Check
the pump, wire, and splices for
insulation integrity, by submerging
the pump and wire in a bucket of
water (see figure 3).
g) Install the new high speed
pump by threading it to the dis-
charge pipe, using Teflon tape and a
pipe wrench (do not over tighten).
h) Attach the wire to the dis-
charge pipe with black electricians
tape very 10-15 ft. Install a torque
arrestor above the pump and tape
off the clamps to prevent them from
nicking the power lines.
i) Reinstall the pump in the
well, be careful not to nick the wires.
It is a good idea to recheck the
resistance to ground before recon-
necting the electricity, (the installa-
tion process could have damaged a
wire). A reading above 2
megaohms is good, above 500,000
ohms is okay, above 200,000 ohms
is usable but should be checked
9
periodically, below 200,000 ohms
should be replaced, below 20,000
ohms is dangerous and should be
disconnected and replaced.
j) If the reading is okay recon-
nect the wires at the well head. At
this time disinfecting the well should
be done per local codes.
k) With the power discon-
nected at the entrance box (circuit
breaker box), change the control
boxes (old two wire units will not
have a control box). After the new
box is installed connect the power
lines and the pump leads to the box.
Make sure you also connect the
grounds from each to the new box.
To minimize any possible radio
interference make sure all exposed
wires are twisted. The box should
be installed above any possible
flood level, it should be mounted to
a dry wall out of reach of small
children. (Do not mount in a flat
position air must rise through the
heat sink) the box should be
mounted indoors protected from the
weather. Make sure the incoming
power agrees with the rating of the
box. Check the circuit breaker at
the entrance box it should be a 15
amp breaker for ¥2 HP and 20 amp
breaker for 1 HP.
I) Disconnect the old pressure
switch, and install the new pressure
switch, use Teflon tape (be careful
not to overtighten). Run the pres-
sure switch wire to the control box.
The circuit runs on 12 volts and 30-
40 milliamps, no ground is required.
The switch comes set at 50 psi to
raise or lower the pressure turn
clockwise to raise the pressure or
counter clockwise to lower the
pressure.
m) Check the tank pressure it
should be set 20 psi under the
pressure setting of the switch.
n) After turning the power on it
takes 10 seconds before the pump
will start.

Connecting Bleed-back
to installation diagram on page 11
and the table at left for recom-
mended distances on various tank
sizes.
b) Connect all piping as shown in
diagram.
c) Start pump. Pressure in tank
will build up to cutoff pressure of
switch setting.
d) After pump has cutout, open
faucet and drain tank pressure to
cutin point of pressure switch.
e) Run the automatic cycle
several times and check the air
charging cycle. Each time the pump
stops, the surface check valve
closes and water starts to drain
back through the bleeder valve.
This causes a vacuum in the
discharge pipe and air is drawn in
through the snifter valve installed in
the check valve. Water will drain
down to the bleeder valve, filling the
pipe between the check valve and
bleeder valve with air. When the
pump restarts, this air will be forced
ahead of the water into the pressure
tank. This method always supplies
excess air which is vented off by the
automatic air volume control.
f) To check proper operation, a
vacuum should be felt at the snifter
vaive when pump stops. (See
illustration for position of bleeder
valve, check vaive and snifter
valve.)
© Controlling Weak Wells
the flow valve method is the
simplest way to prevent drawdown
to pump inlet. The capacity of the
pump discharge is throttled to equal
the well yield. A Dole Flow Valve
delivers a constant capacity regard-
less of pump discharge pressure.
The flow valve is installed in the
discharge line between the pump
and the pressure tank. The usual
way to determine what size of flow
valve to use is to throttle the dis-
charge gate valve to a capacity that
the well will yield without drawing
down. After pump has operated at
this capacity for a sufficient time to
be sure it is suitable, measure the
flow in gallons-per-minute and
select a flow valve size nearest to
this capacity. Install the flow valve
and recheck to be sure operation is
satisfactory.
Dole "low Control Valve
О Trouble-Shooting
The vast majority of service calls
on waterwell systems are caused by
either waterlogged tanks or by
problems which are electrical in
nature. The Myers submersible
pump and waterwell system should
be checked periodically for quality of
water, drawdown, pressure, GPM,
cycling periods (how often the pump
starts and how long it runs) and
proper operation of all automatic
controls.
Never operate the pump for long
periods of time with the discharge
valve closed. This could cause
overheating resulting in damage to
the pump and its motor. A properly-
sized relief valve should be installed
before the tank to prevent the pump
from operating with the discharge
valve closed.
Familiarize yourself with potential
problems and troubleshooting
solutions.
