Pentair S33 service manual Running the pump continuously, Piping, Pump Motor

IMPORTANT INSTRUCTIONS BEFORE INSTALLATION

Failure to follow these instructions may cause serious bodily injury and/or property damage.

Warranty void if product modified, drilled, painted, or altered in any way; if used to pump hot water, or to pump liquids other than water (such as but not limited to chemicals, fertilizers, flammable

liquids, herbicides, mud, tar, cement, wood chips); or otherwise abused.

WARNING, risk of electric shock – This pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, grounding-type receptacle. This pump has not been investigated for use in swimming pool areas. DO NOT WORK ON PUMP UNTIL POWER IS UNPLUGGED. DO NOT cut off ground pin or use an adapter fitting. DO NOT use an extension cord. The pump power cord should be connected to a separately fused, grounded 115 volt line with a capacity of 15 amps. NEVER touch the pump when it is connected to electrical power.

1.Before installing or servicing your pump, BE CERTAIN pump power source is disconnected.

2.Installation and electrical wiring must adhere to state

and local codes and must be complete before priming pump. Check appropriate community agencies, or contact local electrical and pump professionals.

3.CALL AN ELECTRICIAN WHEN IN DOUBT. Pump should be connected to a separate 15 amp circuit breaker or 15 amp fuse block. Plugging into existing outlets may cause low voltage at motor, causing blown fuses, tripping of motor overload, or burned out motor.

4.A permanent ground connection from pump to the grounding bar at the service panel is mandatory. Myers sump pumps come with a grounding conductor and a grounding- type attachment plug. Do not connect pump to a power supply until permanently grounded. For maximum safety, ground pump to a circuit equipped with a fault interrupter device.

PERFORMANCE TABLE (in gallons per minute)

PUMP	TOTAL HEAD (vertical pumping distance) IN FEET
MODEL	6	8	10	12	14	16	18	20	22	22
S33	33	30	29	27	25	23	17	15	12	2

5.Voltage of power supply must match the voltage of the pump. All Myers sump pumps are factory preset to 115V, 60Hz.

6.Before installing pump, clear sump basin of any water, debris, or sediment.

WARNING: Sump basin must be vented in accordance with local plumbing codes. Myers sump pumps are not designed for and CANNOT be installed in locations classified as hazardous in the National Electric Code, ANSI/NFPA 70.

7.The sump basin should be between 14" and 18" in diameter for the S33A1, S33P-1, S33A1C, S33PC-1, S33M1C and 12"–18" for the S33V1, S33V1C, S33PV1 made of plastic, fiberglass, or concrete.

8.The following may cause severe damage to pump and will void warranty:

•Using the pump without a check valve.

•Using an extension cord.

•Cutting off the ground pin or using an adapter fitting.

•Working on pump or switch while plugged in.

•Removing motor housing, unscrewing impeller, or otherwise removing impeller seal.

•Running the pump continuously.

•Pumping chemicals or corrosive liquids.

•Pumping gasoline or other flammable liquids.

PIPING

Plastic PVC pipe is shown in the illustrations, but drain hose, galvanized steel or copper pipe may be used if desired. All piping must be clean and free of all foreign matter to prevent clogging. Use thread compound on all threaded joints unless specified otherwise.

9.Do not open pump housing to attempt repair–this will cause a severe shock hazard.

10.Any finished basement or living area should be equipped with a sump pump alarm to warn of a pump failure and protect against water damage.

11.Cycle the pump at least once per month when regular use isn’t occurring.

12.Always use a properly installed check valve with this sump pump.

A CHECK VALVE MUST BE USED IN THE DISCHARGE LINE FOR ALL PUMPS. A shut-off valve should be used. Always install check valve with arrow on body in direction of flow.

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.
