PENTAIR Myers S4 Sump and Effluent Pumps Instruction Manual

PENTAIR Myers S4 Sump and Effluent Pumps

SAFETY PRECAUTIONS

All Myers sump pumps are grounded to prevent electrical shock. POWER CORD MUST BE PLUGGED INTO GROUNDED TYPE RECEPTACLE. A separate circuit breaker or fuse block should be used for the pump and 15 amp circuit breaker or fuse should be used. Receptacle must be installed at least 4 feet above floor level to prevent tampering by small children and to be out of possible flooding range. Be careful with power cord to prevent cutting or pinching.
DO NOT USE AN EXTENSION CORD WITH SUMP PUMP. DO NOT CUT OFF GROUND PIN OR USE AN ADAPTER FITTING. DO NOT WORK ON PUMP OR SWITCH UNTIL POWER CORD OR CORDS ARE UNPLUGGED.
Sump basin 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.

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.

PUMP DESCRIPTION

The S4 is offered for either 115 volt or 230 volt–single phase–60 hertz. The S4 sump pumps can be used to pump any basement drainage water. NOT TO BE USED FOR SEWAGE WATER EXCEPT TO PUMP SEPTIC TANK EFFLUENT.
The S4 can be used to pump septic tank effluent but must be installed in separate tank or compartment at the discharge side of the septic tank. NEVER INSTALL PUMP DIRECTLY WHERE SLUDGE COLLECTS.
For septic tank pumping the automatic pumps should be used with a junction box. The manual pumps should be used with a junction box and an MLC level control. When a junction box is used, cut off the plugs on the pump cord and the MLC switch cord and strip ends. The MLC switch must be connected in series with one line. This provides a completely sealed system for power cord and pump cord with no open receptacles or taped connections that can cause electrical failure. The S4 sump pumps can be installed in any open or closed type sump basin with a diameter of 12 to 18 inches. A polyethylene, fiberglass or concrete tile basin may be used. If concrete tile is used, cement should be poured in the bottom to give a smooth surface free of stones.

PIPING
Pumps can be installed with ABS, PVC, polyethylene, galvanized or copper pipe. Proper adapters are required to connect plastic pipe to pump. The S4 discharge is threaded for 1-1/2 inch pipe.
NOTE: DO NOT USE THREAD COMPOUND OR OVERTIGHTEN DISCHARGE PIPE INTO PUMP PLASTIC DISCHARGE FITTING.
A CHECK VALVE MUST BE USED IN THE DISCHARGE LINE FOR ALL PUMPS. A shutoff valve should be used with all S4 sump pumps. Always install check valve with arrow on body in the direction of flow.

AIR LOCKING
A sump pump is said to be air locked if water traps air in the pump and the air cannot get out, thus preventing pump from operating.
ALL MYERS SUMP PUMPS HAVE A SMALL AIR VENT HOLE IN THE IMPELLER CHAMBER TO LET OUT TRAPPED AIR. IF THIS HOLE BECOMES PLUGGED, PUMP MAY AIR LOCK. THIS USUALLY HAPPENS ON PUMPS THAT ARE USED MAINLY IN THE WET SEASONS. IN SUMMER MONTHS, THE PUMP MAY BE TURNED OFF AS SUMP WATER DRIES UP. WHEN PUMP IS TURNED ON AGAIN AND WATER COMES UP IN SUMP, THE AIR WILL TRAP IN PUMP IF NOT VENTED. AS A SECONDARY PRECAUTION IN INSTALLATIONS OF THIS TYPE – 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.

STARTING PUMP – S4A (AUTOMATIC)

1.  These pumps have an integral mechanical ball float switch as shown on installation drawing.
2. The S4A1C is for 115 volts and S4A2C is for 230 volts. Plug cord into the proper voltage GROUNDED RECEPTACLE. The 115 volt plug will not plug into a 230 volt receptacle and vice versa.
3.  Run water into sump until pump starts.
4. Allow pump to operate through several on-off cycles to be sure operation is satisfactory.
5.  If shutoff valve is used in discharge line, be sure valve is open.

NOTE: TETHER LENGTH OF SWITCH CORD MUST BE A MINIMUM OF 3-5/8″.

STARTING PUMP – S4M (MANUAL) USING MFS SWITCH WITH SERIES PLUG

1. Install unit as shown on the installation drawing. Secure ball float to discharge pipe with minimum 3- 1/2 inches between float and cable tie.
2. The S4M1C is for 115 volts and the S4M2C is for 230 volts. Plug MFS switch cord series plug into proper voltage GROUNDED RECEPTACLE.
3. Plug pump cord plug into back of switch cord series plug.
4.  Run water into sump until pump starts. The level should be 12 to 13 inches above sump bottom.
5.  Be sure gate valve in discharge line is open.

NOTE: TETHER LENGTH OF SWITCH CORD MUST BE A MINIMUM OF 3-5/8″.

USING THE S4M FOR MANUAL OPERATION

The pump cord for these units can be plugged directly into proper GROUNDED RECEPTACLE for continuous pump operation.
CAUTION: THIS TYPE OF OPERATION SHOULD BE USED ONLY FOR EMERGENCY USE OR WHERE A LARGE VOLUME OF WATER IS TO BE PUMPED, SUCH AS A FLOODED BASEMENT.
PUMP MUST NOT RUN CONTINUOUSLY OUT OF WATER. DO NOT USE WITH EXTENSION CORD.

AUTOMATIC/MANUAL MODEL
The model S4 sump pumps can be changed from one style, automatic or manual, to the other by only interchanging the plug ends of the float control with the manual plug. The ball floats must be tethered with a cable clamp, as shown. DO NOT REMOVE THE MOTOR CAP.

HOW MECHANICAL SWITCH FLOAT OPERATES

This level control uses a mechanical switch sealed in a polypropylene float cylinder. The switch is not position sensitive; that is, it will operate regardless of position. When level rises in the sump, the cylinder floats up with the level. When the cylinder position is at an angle of about 45°, the steel ball rolls over a detent and activates the switch. This starts the pump motor. As the sump level draws down, the cylinder floats down and when it is again at an angle of about 45°, the steel ball drops away, deactivating the switch and the motor stops.
BE SURE CYLINDER FLOATS FREELY IN SUMP BASIN WITHOUT TOUCHING THE BASIN WALLS. ADJUST PUMP POSITION IN SUMP IF NECESSARY.

PUMP MOTOR
NEVER REMOVE MOTOR HOUSING OR UNSCREW PUMP IMPELLER. Warranty on pump is void if motor housing, impeller or seal have been removed. Any repair on motor must be done by an authorized Myers service center.

CLEANING FLOAT
If pump becomes inoperative because of accumulation of trash on the float, remove pump from sump and clean float.

1.  Wipe all water and dirt from pump and float.
2. Be sure float operates freely after cleaning.

CLEANING IMPELLER AND VOLUTE CASE

1. Remove the 5 screws that hold the lower plastic base to the plastic volute case.
2. Use screwdriver to separate the plastic parts. Use care not to gouge a groove in the plastic. Pry in several spots to loosen.
3. Remove loosened part and clean impeller and volute passage.
4. Be sure impeller turns freely after cleaning.
5. Clean out holes in plastic pump base and wash thoroughly before replacing.
6. DO NOT UNSCREW IMPELLER.
