PUMP MODELS
These instructions cover the installation of the 4V,
4VH, 6VH, 4R, 4VC and 6VC series of solids handling
pumps. All models are designed for handling raw
sewage and wastewater.
The 4R series is made with a recessed impeller. All other
models have 2 vane solids handling impellers. All models
will pass 3" dia. solids.
All models with 4 in the model number have a
4" std. flange discharge.
All models with 6 in the model number have a
6" std. flange discharge.
VOLTAGES
All single phase motors are for 230 volts only. All three
phase motors are either 200, 230, 460, or 575 volts. Most
4VC and 6VC models can be configured for 230 or 460
voltages. All 200 volt and 575 volt motors are single voltage.
DESCRIPTION OF PUMP
For the 4R, 4V and 4VH models, pressure connectors
are used on wire connections inside motor cover. The
4VC and 6VC series have terminal connections inside the
motor cover. Power cord and cap can be removed without
disturbing motor on 4VC and 6VC units.
WARNING: Only qualified persons shall conduct services
and installations of this pump. The pump must be wired by
a qualified electrician, using an approved starter box and
switching device.
DANGER: Sewage water gives off methane and hydrogen
sulfide gases, both of which are highly poisonous.
It is for this reason that Myers®recommends the lift-out
check valve so that no service is required in the basin.
Consult federal, state and local codes for confined space
entrance guidelines.
CALIFORNIA PROPOSITION 65 WARNING:
This product and related
accessories contain chemicals known to the
State of California to cause cancer, birth
defects or other reproductive harm.
SEAL FAILURE
All motors have a probe installed in seal chamber so
that any leakage past the lower seal into seal chamber
is detected.
A red warning light at the control panel comes on if water
enters seal chamber. This is an indicator only and does
not stop motor, but warns that seal should be replaced
immediately to prevent motor damage. Pump must go to
authorized service facility for seal replacement.
HEAT SENSOR
All motors have a heat sensing thermostat installed in
top winding of motor. Any motor winding temperature
above 248°F for 4R, 4V, 4VH, 6VH and 266°F for 4VC,
6VC will open thermostat and stop motor. Thermostat will
automatically reset as soon as it has cooled.
CAUTION: Automatic (reset) motor can start at any time
after thermostat is tripped so never do service work on
pump unless power supply is disconnected.
IMPORTANT: Be sure heat sensor wires and seal failure
wires are connected at panel terminal block. Warranty is
void if wires are not connected or are jumped.
MOTOR POWER CABLE AND
CONTROL CABLE
Each pump motor is furnished with a power and control
cable. Longer than standard cord lengths are available on
request.
Each power cord has four conductors – white, black,
red and green. For 3 phase, the red, black and white
conductors connect to the three line leads and the green is
connected to a good outside ground. Interchanging any two
leads reverses the motor.
For single phase, the white and black leads connect to the
two line terminals and the red connects to the start winding
terminal. The green is for ground and must be connected
per NEC.
The control cable has five conductors – black, white,
red, orange and green. White and black connect to heat
sensor terminals; red and orange connect to the seal failure
terminals and green connects to the ground terminal.
APPLICATION
All Myers solids handling pumps can be used to pump raw
sewage, storm water and other wastewater. Do not use for
acid water. Maximum solid size for all units is 3" diameter.
SINGLE PHASE MOTORS
Single phase motors are for 230 volts only. A special
control panel with start and run capacitors and start relay is
required for these pumps.
These control panels must be obtained from Myers or must
be approved by Myers or warranty on pump is void.
OIL FILLED
Motor chamber and seal chamber are oil filled for coolest
running, best heat transfer and best lubrications for
bearings and seals. Motor requires no oiling or greasing.
Motor is sealed for life of bearings.

3
POWER CORD SIZES
Power cord gauge size is determined per NEC.
Motors are generally furnished for single voltage, but
the larger motors in the 4VC and 6VC pumps can be
configured for dual voltage. Dual voltage configuration
is for 230 or 460 volt only. When ordering a dual voltage
capable pump, the cord size for the lower voltage must
be used. 200 and 575 volt motors are single voltage only.
CAUTION: Never pull pump or work on control box
until incoming power is disconnected. Never run motor
until green ground conductor is connected per NEC at
control box.
MAKING ELECTRICAL CONNECTIONS
1. Level controls are held by support bracket
and cords are adjusted for proper depth.
a. Lower turnoff control should be set so
that pump stops when water level is
about at top of check valve or straight
through casting.
b. Upper turn-on control is set to start
pump when level is at height specified
above pump.
c. Override control is set at height
specified above upper turn-on control.
d. Alarm control is set about 6" to 12"
above override control.
e. No control should be set above
inlet invert.
2. If control panel is mounted directly on basin
top, the power and control wires are taken
directly to control box and are sealed in the
cord plate with cord grip connectors.
3. If panel is installed remote from basin
the cords can be taken through a conduit
to control panel, or junction box can be
used in the basin to make connections.
The Myers junction box has a built-in
sealing connector to seal the outgoing
wires. If other than Myers junction box
is used, a separate sealing connector
must be used where wires leave the basin.
CAUTION: If cords are taken directly through a
conduit to control box, a seal fitting must be used at
inlet of conduit to prevent gas vapors from getting to
control box. This type of installation is generally not
recommended because the sealing cement must be
broken to remove a cord.
SINGLE PHASE MOTORS
Single phase pumps have only one rotation and do not
need to be checked.
THREE PHASE MOTORS
Rotation for three phase motors must be checked. The
pump impeller should rotate counterclockwise when
looking at the suction end of pump. To reverse rotation,
interchange any two line leads to motor.
CAUTION: Pump motor is not to be taken apart in the
field. Motors under warranty must be serviced by a
Myers authorized repair facility or be sent to factory.
50 CYCLE PUMPS
All Myers 60 cycle solids handling, three phase pumps
can operate on 50 cycle power at reduced performance.
60 cycle, 460 volt pumps should operate on 380 volt,
50 cycle. Single phase, 60 cycle, 230 volt pumps can
operate on 220 volts, single phase, 50 cycle.
REMOVING PUMP CASE AND IMPELLER
In case of wear, damage due to dropping, plugged
pump, or replacing a defective motor, the pump volute
case and impeller can be removed in the field.
1. Remove bolts between seal housing flange and
volute case. The motor and impeller can now be
lifted off as a unit.
2. If necessary to remove impeller, lay pump on its side.
With a screwdriver bend the tabs of the lock washer
away from the head of the hex head bolt.
3. Loosen and remove the bolt by turning
counterclockwise. Since Loctite®is used to secure
the bolt and is applied to the shaft/impeller interface,
heating of the shaft end to 450° or 500°F will usually
be required.
4. Impeller is mounted by a straight fit with driving key.
Pry evenly on opposite impeller sides with two large
screwdrivers or small bars behind the impeller.
5. Set motor on end with shaft up after removing
impeller so that oil will not drain past the seal.
REPLACING IMPELLER AND PUMP CASE
1. Before reassembly, apply Loctite®#680 in keyway,
impeller bore (lower shaft O.D.), and on the threads
of the hex head cap screw.
2. Before placing the impeller on the shaft, be sure the
mechanical seal and its spring are in place.
3. Position retaining washer with long pin extension in
keyway.
4. Assemble hex head cap screw and tighten securely.

TROUBLE CHECK LIST
Troubles listed are generally caused by the pump. Other trouble can occur from faulty control box operation.
These will be listed with the control box instructions.
CONDITION PROBABLE CAUSE
Pump runs but does not pump
liquid from basin.
1. Pump impeller may be air locked. This occasionally occurs on
a new installation. Start and stop pump several times to purge air. Be
sure air vent hold in volute case is clean.
2. Run additional water into basin so that pump will be
submerged deeper to clear air.
3. If pump is three phase, rotation may be wrong. See
instructions for checking proper rotation.
4. If pump has been installed for some time and does not pump,
it may be clogged at inlet.
5. Discharge gate valve may be closed.
6. Discharge check valve may be clogged or have a broken
clapper or spring.
7. Discharge head may be too high. Check elevation.
8. If above checks do not locate trouble, motor rotor may be
loose on shaft which allows motor to run but will not turn
impeller or only at low RPM.
Checking for Moisture in Motor: Use ohmmeter
and set on highest scale. Readings on the large power
cord between any of the conductors red, black, white
to green conductor or motor housing should be more
than 500,000 ohms.
Readings should be taken with line leads
disconnected from terminal strip.
Resistance of Windings: Every motor winding has
a fixed resistance. Winding must check close to the
specification values to operate properly. This winding
resistance also shows if motor is connected for
voltage being used. Use ohmmeter for this test and
set on scale to read directly in ohms.
CHECK LIST IF PUMP DOES NOT OPERATE PROPERLY

TROUBLE CHECK LIST (Cont’d)
CONDITION PROBABLE CAUSE
Red light comes on at control box.
Overload trips at control box
and alarm buzzer or flashing
red light comes on due to high
water level in basin.
Yellow run light stays on
continuously.
Circuit breaker trips.
Pump is noisy and pump rate
is low.
Grease and solids have
accumulated around pump
and will not pump out
of basin.
This indicates some water has leaked past the lower seal
and has entered the seal chamber and made contact with
the electrode probe. Pump must be removed from basin
immediately for replacement of lower seal. This preventive
repair will save an expensive motor.
1. Push in on red reset button to reset overload. If overload
trips again after short run, pump has some damage and must
be removed from basin for checking.
2. Trouble may be from clogged impeller causing motor to
overload or could be from failed motor.
3. Trouble may be from faulty component in control box. Always
check control box before removing pump.
1. Indicates H-O-A switch may be in the Hand position.
2. Level control switch may have failed causing pump to
continue to operate when water is below lower control.
3. Impeller may be partially clogged causing pump to
operate at much reduced capacity.
4. Gate valve or check valve may be clogged causing low pump flow.
5. Pump may be air logged.
1. Reset breaker by pushing clear down on handle then back
to On position. If breaker trips again in few seconds it indicates
excessive load probably caused by a short in the motor or
control box. Check out instructions given with control box
before pulling pump.
2. If this condition happens after an electrical storm, motor or
control box may be damaged by lightning.
3. Resistance reading of the motor with lead wires disconnected
from the control box can determine if trouble is in motor or control box.
1. Impeller may be partially clogged with some foreign objects
causing noise and overload on the motor.
2. Impeller may be rubbing on wear ring due to bent shaft or misalignment.
3. Pump may be operating too close to shut-off. Check head.
1. Lower weight of level switch may be set too high.
2. Run pump on Hand operation for several minutes with small
amount of water running into basin to clean out solids and
grease. This allows pump to break suction and surge which
will break up the solids. If level switch is set properly this
condition generally will not occur.
3. Trash and grease may have accumulated around floats
causing pump to operate erratically.
