Pentair Myers S4 User manual

Brand: Pentair

Model: Myers S4

Type: User manual

Pentair Myers S4 sump and effluent pumps are designed for removing excess water from various collection basins. These pumps can handle basement drainage, septic tank effluent, and can also be used to pump floodwater from basements. The pumps are easy to install and can be used with various piping materials. The S4 pumps have a built-in mechanical ball float switch that activates the pump when the water level rises and turns it off when the water level drops. The pumps also have a thermal overload protector to prevent damage in case of overheating.

SUMP AND EFFLUENT PUMPS

INSTALLATION AND SERVICE MANUAL

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.

23833A128 11/08/12

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.
