NOTE: READTHESE INSTRUCTIONS
CAREFULLY BEFORE ATTEMPTINGTO
INSTALL PUMP.
DESCRIPTION AND APPLICATION
SSM33, SSM33I and SRM4
Myers SSM33, SSM33I and SRM4 Series Pumps are single
seal units, available in automatic or manual. The SSM33
and SSM33I series pumps are designed for normal sump
and dewatering, and can also be used in effluent applica-
tions. When used in effluent dosing or S.T.E.P. applications,
the pump must be installed in a separate tank or compart-
ment at the discharge side of the septic tank. NEVER
INSTALL PUMP IN MAINTANK WHERE SLUDGE COL-
LECTS. DO NOT USETHE SSM33 OR SSM33I PUMP
SERIES FOR RAW SEWAGE. The SRM4 series pumps are
designed for residential sewage and dewatering applications
where a larger solid size is required.
General
The SSM33, SSM33I and SRM4 pumps use shaded pole,
1550 RPM motors. SSM33 and SSM33I are available in 115
volt only and the SRM4 is available in 115 or 230 volt and all
are single phase only. Both the manual and automatic
models come standard with a 10 ft. power cord. A 20 ft. cord
and switch length are optionally available. All automatic
models come with a mechanical (mercury free) piggy-back
float switch or a vertical float switch. The SSM33 and
SSM33I pumps are designed to handle 1/2” spherical solids
and have a 1-1/2” NPT discharge threading. The SRM4
pumps are designed to handle 2” spherical solids and have
a 2” NPT discharge threading. The SSM33, SSM33I and the
SRM4 use an engineered thermoplastic vortex impeller
designed to efficiently produce the required pressures and
flows.
WARNING! THESE PUMPS ARE NOT APPROVED FOR,
AND SHOULD NOT BE USED IN SWIMMING POOLS,
FOUNTAINS OR PUMPING POTABLE (DRINKING)
WATER.
AIR LOCKING
A pump is said to be air locked if water traps air in the pump
and it cannot get out, thus preventing the pump from
operating.
The SSM33, SSM33I and SRM4 sump pumps have a 1/16”
air vent hole in the impeller chamber to let out trapped air. If
this hole becomes plugged, pump may air lock. As a
secondary precaution a 1/8” hole should be drilled in the
discharge pipe below the check valve. The check valve
should be 12 to 18 inches above pump discharge. Do not
put check valve directly into pump discharge opening.
PACKAGING
Each pump is packaged separately in a carton marked with
a catalog number and Myers engineering number. The
pumps are carefully packaged to prevent damage in
shipping. However, occasionally damage may result due to
rough handling. Carefully go over the pump and check for
damage that could cause the pump to fail.
LEVEL CONTROLS
The automatic models come with 10’ or 20’ power cord and
mechanical (mercury free), piggy-back float switch. The 115
or 230 volt piggy-back switch is tethered directly to the
pump. The switch can optionally be mounted to the dis-
charge pipe using a minimum 3-5/8” tether length. The
switch must float free from pump and basin wall. Plug the
switch cord plug into a properly grounded, rated voltage
receptacle. Plug the power cord into the back of the switch
cord and tape the cords to the discharge pipe every 12”.
The power receptacle must be located outside the wet sump
or basin due to the DANGER of current leakage.
On all duplex units or simplex installations with additional
options like high water alarm, the power cord plug must be
cut off and wired into a control panel or into a sealed
junction box if used in wet sump or basin. The AWS-1
control also acts as a sealed junction box for connecting
power cord to pump cord.
DESIGN OF PRESSURE SEWER SYSTEMS
Myers has available complete computer SOFTWARE for
designing PRESSURE SEWER SYSTEMS. This gives pipe
sizes to use and gives exact flow from any pump or group of
pumps in the system when operating simultaneously.
This design DISK for IBM®or COMPATIBLE computers is
available to engineers on request.
MOTORTYPE
The motors used in these pumps are pressed into the cast
iron housings and surrounded by dielectric oil for superior
heat transfer. Both models use a shaded pole, 1550 RPM
motor. The SSM33 and SSM33I are rated at 1/3 HP and the
SRM4 is rated at 4/10 HP. All units have class A motor
insulation. SSM33 and SSM33I are available in 115 volt,
single phase only and SRM4 is available in 115 or 230 volt,
single phase. All have overload protection, and use a
double sleeve bearing design. These pumps have no
starting switches and do not require a control panel for
simplex installation.
SAFETY WARNINGS
WARNING: Risk of electric shock. Pumps are supplied with
a grounding conductor and grounding-type attachment plug
on the power cord. To reduce the risk of electric shock, be
certain that it is connected only to a properly grounded,
grounding-type receptacle. DO NOT cut off ground pin or
use an adapter fitting. DO NOT use an extension cord with
this pump.
All pumps have a GROUND WIRE that is connected to the
motor. This wire goes to the receptacle or control panel
which must be connected to a good outside GROUND.
When wiring this pump follow all local electrical and safety
codes and ordinances as well as the most recent National
Electric Code (NEC-ANSI/NFPA 70).
UL AND CSA APPROVAL
All pumps have UL and CSA approval pending. Myers is a
SSPMA certified pump member.

INSTALLATION
WARNING: Basin or tank must be vented in accordance
with local plumbing codes. These pumps are not designed
for and CANNOT be installed in locations classified as
hazardous in accordance with the National Electric Code
ANSI/NFPA 70.
CAUTION: Never enter pump chamber after sewage or
effluent has been in basin. Sewage water can give off
methane, hydrogen sulfide and other gasses which are
highly poisonous. For this reason, Myers recommends
installing effluent pumps with a quick removal system. The
quick removal system may be a union or Cam-lok® coupling
if the pipe or discharge hose is within reach from the
surface, or a rail system type quick disconnect on deeper
installations. See installation drawings for suggested
installation.
The dosing tank or pumping chamber must be constructed
of corrosion resistant materials and must be capable of
withstanding all anticipated internal and external loads. It
also must not allow infiltration or exfiltration. The tank must
have provisions for anti-buoyancy. Access holes or covers
must be adequate size and be accessible from the surface
to allow for installation and maintenance of the system.
Access covers must be lockable or heavy enough to prevent
easy access by unauthorized personnel. The pumping
chamber holding capacity should be selected to allow for
emergency conditions.
The discharge pipe must be the same size as the pump
discharge 1-1/2” for SSM33 and SSM33I, 2” for SRM4 or
larger. In order to insure sufficient fluid velocity to prevent
any residual solids from collecting in the discharge pipe, it is
recommended that a minimum flow of 2’per second be
maintained. (12 GPM through 1-1/2” pipe, 21 GPM through
2” pipe and 46 GPM through 3” pipe). It is recommended
that PVC or equal pipe is used for corrosion resistance. A
full flow (ball or gate) shut off valve must be installed to
prevent back flow of effluent if the pump must be removed
for service. A check valve must be installed on pressure
sewer systems and on other systems where conditions allow
to prevent backflow and to reduce wear on the pump
system.
A high water alarm must be installed on a separate circuit
from the pump circuit. The alarm should have the ability to
be tested for proper operation.
POINTSTO CHECK IF PUMP DOES NOT
RUN OR DOES NOT RUN PROPERLY
(1) Pump does not run or start when water is up in tank.
(a) Check for blown fuse or tripped circuit breaker.
(b) Check for defective level switch
(c) Where control panel is used be sure H-O-A switch is
in the AUTO position. If it does not run, turn switch to
the HAND position and if the pump runs then the
trouble is in the automatic electrical system. Have
ELECTRICIAN make electrical checks.
(d) Check for burned out motor. Occasionally lightning
can damage a motor even with lightning protection.
(e) Where plug-in cords are used be sure contact blades
are clean and making good contact. DO NOT USE
PLUG-IN CORDS INSIDE A SUMP OR WET WELL.
(f) Level control ball or weight may be stuck on side of
basin. Be sure it floats freely.
(2) Pump runs but does not deliver flow.
(a) Check for airlock. Start and stop pump several
times, if this does not help it may be necessary to
loosen a union in the discharge line to relieve airlock.
(b) Check valve may be installed backwards. Check flow
arrow on valve body. Check shut-off valve. It may be
closed.
(c) Check vertical elevation. It may be higher than pump
can develop. (See pump curve).
(d) Pump inlet may be plugged. Remove pump to
check.
CAUTION: ALWAYS UNPLUG POWER CORDS ORTURN
OFF ALL MAIN AND BRANCH CIRCUIT BREAKERS
BEFORE DOING ANYWORK ONTHE PUMP. If control
panel is remote from pump, disconnect lead wires to motor
so that no one can turn the circuit breaker back on.
BEFORE DISMANTLING PUMP FOR
REPLACEMENT OF PARTS
Clean pump thoroughly. Knock off all scale and deposits.
Submerge complete unit on Clorox solution for one hour
before taking apart.
