ECO-FLO EFSA50 (01) PDF Document

Always use extreme caution when installing or maintaining your ECO-FLO EFSA50. A sump pump is an electrical device designed to operate in inherently wet environments.

General Safety:

Risk of burns: Do not touch an operating motor. Motors are designed to operate at high temperatures. To avoid burns when servicing the pump, allow it to cool for 20 minutes after shut-down before handling.

Do not allow the pump or any system component to freeze, as this will void the warranty.

Pump water only with this pump.

Periodically inspect the pump and system components.

Wear safety glasses at all times when working on pumps.

Risk of explosion: The pump body may explode if used as a booster pump.

WARNING: Do not work on the pump until power is unplugged.

WARNING: Do not cut off the 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 line with a minimum capacity of 15 amps. It can be connected to a non-fuse breaker at the recommended amperes.

1. Before installing or servicing this pump, be certain the pump’s power source is disconnected.

2. Installation and electrical wiring must adhere to state and local codes and must be completed before priming the pump. Check appropriate community agencies or contact local electrical and pump professionals.

3. Call an electrician when in doubt. The pump should be connected to a separate 15 amp circuit breaker or 15 amp fuse block. Note that plugging into existing outlets may cause low voltage at the motor, which could cause blown fuses, tripping of motor overload, or a burned-out motor.

4. A permanent ground connection from the pump to the grounding bar at the service panel is mandatory. These sump pumps come with a grounding conductor and a grounding-type attachment plug. Do not connect the pump to a power supply until permanently grounded.

5. The voltage of the power supply must match the voltage of the pump.

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

WARNING: The sump basin must be vented in accordance with local plumbing codes. These sump pumps are not designed for and CANNOT be installed in locations classified as hazardous.

The following may cause injury and/or severe damage to the pump and will void the warranty:

(a) Using an extension cord.

(b) Cutting off the ground pin or using an adapter fitting.

(c) Working on the pump or switch while it is plugged in.

(d) Removing the motor housing, unscrewing the impeller, or otherwise removing the impeller seal.

(e) Running the pump continuously.

(f) Pumping chemicals or corrosive liquids.

(g) Pumping gasoline or other flammable liquids.

CAUTION: Check local codes before installing the pump.

STEP 1: The pump must be installed in a suitable sump which is at least 14″ wide.

STEP 2: The pump must be placed on a hard surface in a sump that has been cleared of all debris. Never place the pump on clay, earth, or gravel surfaces. It is suggested the pump be placed on two bricks approximately 2″ apart.

STEP 3: Connect the discharge pipe, fittings, and check valve to the discharge port of the pump. It is recommended that the discharge pipe diameter be equal to or larger than the discharge size of the pump. Discharge piping can be PVC, polypipe, or galvanized steel.

WARNING: Verify that the voltage and frequency of the pump shown on the nameplate correspond to those available on the mains. The installer must make sure that the electric system is grounded in accordance with the code.

• For outdoor use, it is necessary to use a cable with a length of at least 10′. The plug and connection should be protected from water splashes. Before using the pump, always inspect it visually (especially the power cable and plug).

• Do not use the pump if it is damaged.

• If the pump is damaged, have it inspected by an authorized service center.

• Make sure that electric connections are protected from flooding. Protect the plug and the power cable from heat or sharp edges.

WARNING: The power cable must be replaced by qualified personnel only. Grounding: The plug of the power cable has a double grounding contact, so that grounding can be performed by simply inserting the plug.

The ECO-FLO EFSA50 pump series has a built-in thermal protection switch. The pump stops if an overload condition occurs. The motor restarts automatically after it has cooled down. If it doesn’t start automatically, unplug the pump and plug it back in.

If your ECO-FLO EFSA50 does not run and makes a humming sound, check the following possible causes and solutions:

• Line circuit breaker is off, or fuse is blown or loose.

• Water level in the sump has not reached the turn-on level as indicated in the installation drawing.

• Pump cord is not making contact in the receptacle.

• The float is stuck. It should operate freely in the basin.

• If all of the above are OK, then the motor could be malfunctioning.

If your ECO-FLO EFSA50 runs but does not deliver water, consider these possible causes and solutions:

• Check if the check valve is installed backward. The arrow on the valve should point in the direction of flow.

• The discharge shut-off valve (if used) may be closed.

• The impeller or volute openings are fully or partially clogged. Remove the pump and clean.

• The pump is air-locked. Start and stop it several times by plugging and unplugging the cord. Check for a clogged vent hole in the pump case.

• Inlet holes in the pump base are clogged. Remove the pump and clean the openings.

• The vertical pumping distance is too high. Reduce the distance or change the discharge fittings of the pump.

If your ECO-FLO EFSA50 runs continuously and does not stop after pumping out the sump, check these issues:

• The float is stuck in the up position. Be sure the float operates freely in the basin.

• The float switch is defective. Replace the float switch.

If your ECO-FLO EFSA50 is delivering only a small amount of water, investigate these possible causes:

• The pump is air-locked. Start and stop it several times by plugging and unplugging the cord. Check for a clogged vent hole in the pump case.

• The vertical pumping distance is too high. Reduce the distance or change the discharge fitting of the pump. Inlet holes in the pump base are clogged. Remove the pump and clean the strainer and openings.

• The impeller or volute openings are fully or partially clogged. Remove the pump and clean.

• The pump impeller is partially clogged with tar or paint, causing the motor to run slow and overload. Remove the pump and clean.

If the fuse blows or the circuit breaker trips when the ECO-FLO EFSA50 pump starts, check the following:

• The pump impeller is partially clogged, causing the motor to run slow and overload. Remove the pump and clean.

• The motor stator may be defective.

• The fuse size or circuit breaker may be too small (must be 15 amps).

• The impeller or volute opening are fully or partially clogged. Remove the pump and clean.

If the motor on your ECO-FLO EFSA50 runs for a short time and then stops, look into these potential issues:

• Inlet holes in the pump base are clogged. Remove the pump and clean the openings.

• The pump impeller is partially clogged, causing the motor to run slow and overload. Remove the pump and clean.

• The motor stator may be defective.

• The impeller or volute openings are fully or partially clogged. Remove the pump and clean. Also clean the strainer if one is installed.

WARNING: Before servicing a pump, always shut off the main power breaker and then unplug the pump. Make sure you are not standing in water and are wearing insulated protective sole shoes, under flooded conditions. Contact your local electric company or a qualified licensed electrician for disconnecting electrical service prior to pump removal.
