SAFETY INFORMATION

4Part # 23833A627 (09-01-21)
PUMP MODELS
These instructions cover the installation and service of the
Myers pumps as listed on the front cover. The hazardous
location models are Factory Mutual approved and listed
hazardous location for hazardous sewage locations Class 1,
Division 1, Groups C & D.
MOTOR HP AND VOLTAGES
These pumps are offered in a three phase wiring configuration
only. Voltages will vary according to the application.
ELECTRICAL CONTROLS
All of these pump models must be used with a control panel.
Myers built control panels are designed to supply the correct
electrical controls, motor starting equipment and include the
circuitry for moisture and heat sensors. It is recommended that
a Myers built control panel be used so that all warranties apply.
GENERAL CONSTRUCTION
The motor construction is designed to meet Factory Mutual’s
requirements for Class 1, Division 1, Groups C & D sewage
applications. The hazardous location models are certified and
nameplated with this approval. The motor chamber and seal
chamber are filled with a high dielectric type oil for improved
lubrication and heat transfer of the bearings and motor. Since
the bearings have been designed for 50,000 hours of life, the
oil should never require replacement under normal operating
conditions. An air space above the oil level in both the seal
and motor chambers is provided to allow for the expansion of
the oil when at operating temperature. The power and control
lines are sealed and strain relieved by a grommet in the cord
cap, and internally through the use of a dielectric potting resin
surrounding the electrical wires. All of the pump fasteners and
shafts are made from corrosion resistant stainless steel, while
the pump castings are made of ASTM A-48 Class 30 cast iron.
The wear ring is brass and all impellers are two vane enclosed
solids handling design made from ductile iron.
GENERAL INSTALLATION
Various configurations and methods of plumbing this series
of solids handling pumps may be used; however, for ease
of installation and service a Myers 4" rail lift-out system is
recommended.
Note: If the hazardous location pumps are used in conjunction
with a rail lift-out system, it must be an F.M. approved
nonsparking, hazardous location system. The Myers approved
lift-out models are:
4" Liftout 6" Liftout
SRAX44HH SRAX66
If these guidelines are not followed, the Factory Mutual approval
is void.
HAZARDOUS LOCATION SERVICE
These pumps are to be used for handling sewage, wastewater
and storm water only. Do not use in other hazardous locations.
These motors must be repaired and serviced only at Myers
Authorized Service Centers or at the Myers factory. Any
unauthorized field repair voids the warranty, the hazardous
location rating, and Factory Mutual approval.
After the pump is installed and sewage has entered
the basin there are methane and hydrogen sulfide gases, which
are poisonous. Never enter a wet well unless the cover is open
for a sufficient period of time to allow fresh air into the basin.
Myers recommends using the rail lift-out system so that no
service is required inside the basin.
OIL FILLED MOTOR
The motor chamber and seal chamber are dielectric oil-filled
for good heat transfer and lubrication of bearings and seals.
The motor requires no other lubrication. Oil level in the motor
housing should be to the bottom of the oil fill plug with the pump
in a vertical position, ensuring the upper bearing is submerged
in oil. Do not overfill the motor housing since some space is
required for oil expansion. Oil level in the seal chamber should be
checked with the pump lying horizontally with the fill plug at the
top. The oil level should be approximately 3/4" from the outside
surface of the housing. Transformer oil should be used and may
be purchased from your Myers distributor.
Each motor is provided with heat sensor thermostats attached
directly to the motor windings. The thermostats open if the
motor windings see excessive heat and, in turn, open the motor
contactor in the control panel, breaking the power to the pump.
When the motor is stopped due to an overheated condition, it
will not start until the motor has cooled and the heat sensor
reset button is manually pushed on the front of the Myers control
panel. This circuitry is provided in the Myers control panel
designs.
The thermostats are set to open at a temperature of 302º F
(150ºC). The maximum contact rating is 18 amps at 115 VAC and
12 amps at 230 VAC. Motor winding insulation is good for Class F
(311ºF, 155ºC, or higher).
Note: Failure to use proper circuitry and to connect the motor
overheat protection in the control panel would negate all
warranties and Factory MutualApproval.
MOTOR SEAL FAILURE WARNING
The seal chamber is oil filled and provided with moisture sensing
probes to detect water leakage through the lower shaft seal.
The probes can also detect moisture present in the upper motor
housing.
INSTALLATION AND OPERATION

5
Part # 23833A627 (09-01-21)
The presence of water energizes a red seal leak warning light
at the control panel. This is a warning light only, and does not
stop the motor. It indicates a leak has occurred and the pump
must be repaired. Normally, this indicates the outboard seal
has leaked. Allowing the unit to operate after the warning could
cause upper seal leakage along with motor failure.
The resistance across the moisture seal (seal failure) probes
should be checked after a seal leak warning light has lit. This
can be done by disconnecting the red and orange control wires
from the control panel, and measuring the resistance with an
ohmmeter between the wires. If the measured values are below
specification, then the pump may have a lower seal failure and
require service.
On the Myers hazardous location control panels the seal leak
test switch tests the seal leak circuitry continuity. When pushed
the seal leak test bulb should light. If the test bulb does not light
it means either the wiring circuitry to the seal leak probes has
been broken or the bulb has burned out.
Note Myers built control panels supply the correct circuitry for
moisture and heat sensor connections. Failure to install the
correct circuitry with proper connection would negate warranty
and Factory Mutual Approval.
MOTOR POWER CORD, CONTROL CORD AND CORD CAP
ASSEMBLY
Each motor power cord has 4 conductors – white, black, red
and green. For a three phase motor the red, black and white
conductors connect to the three line leads, and the green is
connected to a good ground. Interchanging any two leads will
reverse the rotation of the motor.
Note: Rotation should be clockwise when observed from the top
of the pump. This can be checked by noting which direction the
pump torque is upon initial starting. A properly rotating pump
will torque counter- clockwise upon start.
The control cable has 5 conductors – black, white, red, orange
and green. White and black connect to the heat sensor
terminals in the control panels; red and orange connect to
the seal failure terminals in the control panel; and the green
connects to the ground in the control panel.
The cord cap is epoxy potted. The cord cap provides for a
sealed wire connection with terminals so that connections can
be made without breaking the motor seal. This allows the cord
cap, with cords, to be removed from the motor. An approved
hazardous location junction box is required for hazardous
locations.
Note: Each cable has a green ground wire and must be properly
grounded per the National Electric Code and local codes.
ELECTRICAL MOTOR CONTROLS
All electrical controls and motor equipment should be as
specified in these instructions. Consult factory for any
acceptable alternatives. For hazardous locations the controls
and control panel must be installed outside the hazardous area,
or approved hazardous location controls that are intrinsically
safe must be used.
JUNCTION BOX
If a junction box is used in a hazardous location, it must be a
hazardous location approved type with hazardous location cord
connectors. Wires from the junction box must pass through a
hazardous location seal connector.
LEVEL SENSING CONTROLS
Intrinsically safe type float controls are recommended for all
applications and required for hazardous location service. An
intrinsically safe control panel relay will limit the current and
voltage to the level controls. A Myers control panel can be
supplied with this type circuitry.
The float level controls maintain the basin sewage water level by
controlling pump turn-on and turn-offlevels.
1. The lower turn-off control should be set so that the pump
stops at approximately the top of the pump. Consult the
factory for any settings below thispoint.
2. The upper turn-on control should be set above the lower
turn-off control. The exact height between the controls is
determined by the number of pump starts desired and the
depth of the basin. A maximum of 10 starts per hour should
not beexceeded.
3. The override control is set at a specified height above the
upper turn-on control.
4. The alarm control is set about 6" to 12" above the override
control.
5. No control should be set above the inlet invert.
ELECTRICAL CONNECTIONS
All electrical wiring must be in accordance with local code and
only qualified electricians should make the installations. All
wires should be checked for shorts to ground with an ohmmeter
or megger after the connections are made. This is important, as
one grounded wire can cause failure of the pump, control panel
or personal injury.
INSTALLATION AND OPERATIONS

6Part # 23833A627 (09-01-21)
PUMP
The fluid end of the pump is field serviceable and can be
disassembled in case of wear, damage, plugging or outboard
seal failure. The following will describe the disassembly and
reassembly process.
DISASSEMBLY
1. With the pump located in a secure place, remove the bolts
fastening the seal housing to the volute. The motor and
impeller can now be removed as aunit.
2. Lay the unit down on its side. If the lower seal is to be
removed, it is recommended that the oil in the seal
chamber be drained. This can be done by removing the
lower seal chamber plug and draining the oil into a holding
container.
3. To remove the impeller, first remove the bolts from the
nose cone. The nose cone will pull off. Using a proper
wrench, the impeller retaining bolt and washer must
be removed. This may require a piece of wood placed
between the vanes to keep the impeller from rotating while
removing the bolt. Once the bolt has been removed, tap
lightly with a hammer around the outside diameter of the
impeller to loosen from tapered shaft and key.
The impeller is large and heavy and will need to
be supported.
4. If the lower seal needs to be removed, first remove the
compression spring that rides between the impeller and
the seal assembly. Next remove the compression ring
that surrounds the rubber bellows on the rotating portion
of the seal assembly. Again using screwdrivers, pry the
remaining portion of the rotating seal assembly off the
shaft. The ceramic stationary can be removed by placing
a screwdriver between the rubber and the ceramic face
and then prying, working around the entire diameter. Note,
these parts should be discarded and a new seal assembly
installed.
5. If the oil in the seal chamber was drained, examine the
contents to determine if the upper seal has been damaged.
Sign of grit or other abrasive material may indicate that the
upper seal has also been damaged. Pressurizing the motor
housing assembly between 7 and 10 psi and observing
any drop in pressure will indicate if the upper seal is
functioning properly.
Note: Upper seal repairs must be done at a Myers
Authorized Service Center or at the Myers factory. Any
unauthorized field repair voids warranty and the hazardous
location approval on the Factory Mutual listed pump.
6. The wear ring can be removed from the volute for repair or
replacement.
REASSEMBLY
1. Remove the ceramic portion of the new seal from the
package. Brush new dielectric oil around the rubber portion
of the stationary assembly and into the pocket in the seal
housing. Note, keep the oil off the seal face. Without
scratching the seal face, press the ceramic stationary
portion into the seal housing with a Myers® seal pusher.
With clean cloth, lightly wipe the face of the seal surface to
make sure it is dirt free. Remove the rotating portion of the
seal from the package and lubricate the inside diameter of
the rubber bellows and the outside diameter of the shaft.
Place the seal over the shaft (make sure the key is removed).
Evenly press on the body of the rotational assembly and slide
it down the shaft until the seal faces meet. Once the seal
assembly is in position, place the spring over the register on
the rotational portion of the seal.
2. Position the key into the seat of the shaft. Align the impeller
onto the shaft, making sure that the seal spring is registered
properly onto the back side of the impeller. Insert the bolt
and washer assembly into the shaft and tighten. Replace the
nose cone onto the impeller. The proper Loctite® should be
applied to the bolts. Install and tighten.
3. Fill the seal chamber with new dielectric oil. An air gap of
10–15% volume must be left for the expansion of the oil when
it is at operating temperature.
4. The wear ring can be aligned with the retaining holes and
tapped into place with a soft mallet. The proper Loctite®
should be applied to the bolts. Install and tighten.
5. The motor and impeller assembly can be installed into the
volute. Make sure that the impeller aligns properly with the
volute. Install the volute retaining bolts and tighten.
6. Air tends to trap in the pump case when water rises in the
sump or when the pump is lowered into the water after
service. To vent off this air, a small hole is drilled into the
volute casting. Be sure this vent hole is clean after any
service work on pump. Air venting is not a problem after
initialstart.

CHECKING FOR MOISTURE IN MOTOR
Use an ohm - meter or a megger and set on highest scale.
Readings on the large power cord between any of the
conductors red, black or white to the green conductor or to
the motor housing should be greater than 1,000,000 ohms (1
megohm). Service work should be done only at an authorized
service facility. Note, readings should be taken with line leads
disconnected from the control panel.
RESISTANCE OF WINDINGS
Every motor winding has a fixed resistance. The windings must
check close to specification values. Verification of the proper
wiring of a dual voltage motor can also be checked by measuring
the motor winding resistance.
TROUBLESHOOTING
CONDITION PROBABLE CAUSE
Red light comes on at control box.
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 for replacement of lower seal.
This preventive repair will save
an expensive motor.
Overload trips at control box and alarm buzzer
or ashing red light comes on due to high water
level in basin.
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.
Yellow run light stays on continuously.
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 very reduced capacity.
4. Gate valve or check valve may be clogged causing low pump flow.
5. Pump may be air locked.
Circuit breaker trips.
1. Reset breaker by pushing completely down on handle then back to ON position. If breaker
trips again in a 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.
Pump is noisy and pump rate is low.
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.
Grease and solids have accumulated around
pump and will not pump out of basin.
1. Lower control 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.
