NOTE: READ THESE INSTRUCTIONS CAREFULLY
BEFORE ATTEMPTING TO 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
applications. When used in effluent dosing or S.T.E.P.
applications, the pump must be installed in a separate
tank or compartment at the discharge side of the
septic tank. NEVER INSTALL PUMP IN MAIN TANK
WHERE SLUDGE COLLECTS. DO NOT USE THE
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: These 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) piggyback 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. An engineered
thermoplastic vortex impeller designed to efficiently
produce the required pressures and flows is used.
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.
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.
LEVEL CONTROLS
The automatic models come with 10' or 20' power
cord and mechanical (mercury free), piggyback
float switch. The 115 or 230 volt piggyback switch
is tethered directly to the pump. The switch can
optionally be mounted to the discharge 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.
MOTOR TYPE
The motors used in these pumps are pressed into the
cast iron housings and surrounded by dielectric oil
for superior heat transfer. 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).
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.

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 gases 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
antibuoyancy. 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 ensure 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.
POINTS TO 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 backward. 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
OR TURN OFF ALL MAIN AND BRANCH CIRCUIT
BREAKERS BEFORE DOING ANY WORK ON
THE PUMP. If control panel is remote from pump,
disconnect lead wires to motor so that no one can turn
the circuit breaker back on.
TO REPLACE AUTOMATIC FLOAT
1. Unplug the pump power cord from the back of the
piggyback float plug.
2. Unplug the piggyback float plug from the power
receptacle.
3. Remove the pump from the sump if access to the
tether point is inaccessible.
4. Disconnect the switch from its tether point and
remove from the discharge piping.
5. Retether the new cord to the pump or discharge
piping.
6. Cable tie or tape the power and switch cords to the
discharge piping.
7. Plug the switch into the power receptacle.
8. Plug the power cord into the switch plug.
9. Fill basin and test switch operation.
ALL PUMP REPAIRS SHOULD BE DONE AT AN
AUTHORIZED MYERS SERVICE CENTER.
