NOTE: READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL PUMP

DESCRIPTION AND APPLICATION

SM33, 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. DONOT USE THE SSM33 OR SSM33I PUMP SERIES FOR  RAW SEWAGE. The SRM4 series pumps are designed forresidential 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 automaticmodels 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 SRM4use 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 thedischarge 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 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.

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.

MOTOR TYPE

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 whichmust 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.

CSA APPROVED

All pumps have CSA approval. 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 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 thatPVC 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 thetrouble 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 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.

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.
