INTRODUCTION

The Power Pro ESP™ portable electric sampling pump was developed exclusively for low-flowground water sampling. The heart of the pump is a variable speed, brushless motor combinedwith a high-efficiency impeller. This unique combination consumes 50-75% less power (basedon manufacturers’ published specs), which translates to user benefits of less heat, lighter andmore flexible power supply options, and greater reliability than traditional electric samplingpumps.

The unique, all-in-one design features the ESP Communications ProtocolSM, which providessimple pump operation with sophisticated control. The In-Water Sensor indicator lights upwhen the pump is fully submerged, making it easy to position the pump in the well. The Run-Dry Protection limits drawdown and prevents damage to the motor and seal. The pump andreel weighs just 32 pounds, less than any traditional pump/reel/controller combinationcurrently in the market.

SAFETY

Before connecting the pump to an external battery, always be sure that the flow ratecontrol knob is set at minimum (counterclockwise) and that the water discharge hose isdirected into an appropriate container. Failure to do so could result in a splash hazardto personnel or an electric shock hazard if the water discharge is directed at potentialsources of electricity.

Always wear appropriate eye protection, and personal protective clothing. When checking the rotation of the motor during reassembly, always be sure to keep the

motor shaft and impeller away from hair or clothing that could cause an entanglementhazard.

The Power Pro ESP pump is driven by an electric motor. It is not intended for use wheremethane or other flammable materials are present. Consult local authorities andregulations if you have any doubt about its suitability for a specific application.

OPERATING INSTRUCTIONS

1. With the cable reel set in position (hanging from well casing or placed on a solidsurface), pull the retaining pin from the pump holster and remove the pump.

2. Connect discharge tubing or hose to the discharge barb fitting and clamp in place.

3. If a safety cable will be used, attach the cable to the lift eyebolt on top of the pump.

4. Place the pump into the well with the cable reel rotation lock on to prevent the pumpfrom falling.

5. Place the Water Sensor switch in the “ON” position – you should see a flashing greenlight. (If the green LED is not lit, see Troubleshooting instructions.)

6. Place the Run Dry Protection switch in the “ON” position.

7. Lower the pump into the well until the flashing green Water Sensor LED is glowingsteady. This indicates that the pump is submerged. Now, lower the pump to the desiredsampling depth by counting the 1-foot marks on the power cable.

7

8. Set the reel rotation lock, then check to see that the Speed Control knob is set to thefully counter-clockwise “OFF” position. Place the Water Sensor switch in the “OFF”position before connecting the power cord to the reel.

9. Connect the 12-volt power supply cord to the reel. Connect the two terminal clamps toa 12-volt power source (e.g., vehicle battery, portable battery, etc.), making sure thatthe red clamp is clamped to the positive battery terminal, and the black clamp isclamped to the negative battery terminal (connecting these clamps in reverse will blowthe fuse, which is located on the control panel inside the reel hub). Return the WaterSensor switch to the “ON” position and check that the green LED indicator is glowingsteadily.

10. If desired, place the end of the discharge tubing or hose into a clean container of waterto observe when pumping begins (bubbles will escape from tubing).

11. Slowly turn the Speed Control knob clockwise until pumping begins, and then adjust asneeded to reach the desired purging flow rate. The pump flow rate can be decreased asdesired to fill sample containers or to use an in-line QuickFilter® capsule for collectingfiltered samples.

12. Once sampling is completed, turn the Speed Control knob, Water Sensor and Run-DryProtection switches to the “OFF” position and disconnect the 12-volt power supply atthe reel. The pump can now be removed from the well.

13. If more wells will be sampled, follow your desired decontamination procedure and placethe pump back into the storage holster for transport to the next well. If sampling iscompleted, follow the steps under “Preparing Pump for Storage” before storing thepump overnight or longer.

Preparing pump for storage

1. Remove the inlet screen housing as shown by inserting a screwdriver or rod through thelower inlet holes and turning the housing counter-clockwise. (NOTE: Do not attempt toplace anything into the upper inlet holes, as this could damage the inlet screen.)

2. Inspect the inlet screen for debris or solids buildup. If necessary, remove the snap ringretainer and clean the inlet screen.

8

3. At the top of the pump, turn the top retaining collar counter-clockwise to release thepump body, and then slide the body downward off of the pump inner tube.

4. Using a clean cloth or paper towel, dry the outside of the inner tube.

5. Using a ¼-20 bolt or the provided eye bolt, remove the inlet plate and O-ring seal.Remove the impeller. Holding the pump upright, allow any water within the pump todrain out and then dry the inlet area.

6. Reassemble the pump by sliding the pump body back up over the inner tube and lockingthe retaining collar at the top to the body. Reinstall the impeller (or, if worn, replace theimpeller as needed), noting the orientation of the impeller (small ‘donut’ facingoutward). Reinstall the inlet plate and the O-ring seal, and then attach the inlet screenhousing.

7. The level sensor tip at the top of the pump can accumulate anodic iron deposits after afew hours of use. It is recommended that this tip be lightly brushed daily, using a softbristle toothbrush, to prevent excessive accumulation.

8. Place the pump back into the holster on the cable reel for transport and storage.

General Information

1. When the Run Dry Protection is used during pump operation and water level dropsbelow the top of the pump, pump operation will be paused and the green LED willblink. If the water level recovers or the pump lowered in the water column, thepump will turn back on and the green LED indicator will change from blinking to lit.

2. To override run dry protection, such as for decontamination or testing of the pump ina bucket, turn inner switch (run dry protection switch) OFF. In this mode, the pumpwill run continuously regardless of whether there is water present. Avoid extended dryoperation to prevent damage to the motor shaft seal.

9

3. If water pumping doesn't start immediately (typically under low submergenceconditions), a slight shake of the pump up and down will help clear any air bubblesfrom the impeller region.

Cleaning/Decontamination Note

1. The pump inlet assembly has a space below the intake holes and internal intake screenwhere sediment can accumulate after the pump is shut off. As part of the cleaningprocedure, it is important to remove the pump inlet assembly (see “Disassembly”, page10) and flush out the sediment trap and screen, to avoid cross-contamination betweenwells.

10

DISASSEMBLY

Tools needed: Phillips screwdriver – #2 or #3 size Snap ring pliers Adjustable wrench, 12” or larger (must open to 1.5”)

1. Before servicing, always disconnect the pump from the power source.

2. Put a Phillips head screwdriver through the lower holes in the pump inlet housing and twist thehousing counter-clockwise (when looking at the bottom) to release the lower bayonet, and removethe pump inlet from the pump body.

3. The pump inlet screen can now be cleaned by back-flushing with water. If desired, the inlet screencan be removed by removing the snap ring that holds the inlet screen in place.

11

4. Remove the eyebolt from the top of the pump (or use any ¼-20 bolt) and thread it into the inletplate. Using the eyebolt, remove the inlet plate and inlet O-ring.

5. To remove the impeller, turn the pump upright and gently tap the bottom until the impeller fallsout. Clean the impeller if necessary. Replace the impeller if the impeller blades are noticeablyeroded, if there is abrasion on the face of the impeller, or if the “D” shaped hole in the center of theimpeller has worn such that it no longer fits snugly onto the pump shaft.

REASSEMBLYReassemble the pump in reverse order from the above directions, observing the notes below.

1. When installing the impeller, be sure the circular “indent” faces toward the lower end of the pump,and that the impeller is aligned with the “D” flat on the shaft. If the impeller is installed upsidedown, the pump will still pump, but at a greatly reduced flow rate.

12

2. Use the eyebolt from the top of the pump (or any ¼-20 bolt) to install the inlet plate. There are twokey slots on one end of the inlet plate, and one key slot on the other end. Before pushing the inletplate into the pump, rotate it so that the key slots line up with the mating keys on the pump.

3. Install the inlet O-ring, making sure it’s seated in the groove in the inlet plate.

4. If the inlet screen was removed during disassembly, reinstall it in the screen housing and secure it inplace with the snap ring.

13

5. Install the pump inlet onto the pump body by twisting the pump inlet clockwise to engage thebayonet. A screwdriver can be used for leverage (see disassembly instructions).

LED Table 1 – Error Indicator (Amber LED)

This light indicates that an error is present in the system. Errors are displayed continuously and will notbe reset until the operating issue is resolved. If more than one error is present, the most significant error(4 blinks) will be displayed until it has been resolved, then the next most significant error will bedisplayed and so on (a 1 blink error is the least significant error that can occur). To read the error LED,wait for the light to stop flashing (pause) and then observe the next successive blinks. The number oftimes the LED blinks before pausing indicates the error that's present. See the table below for adescription of the error.

LED Table 2 – Pump Runtime Meter (Green LED)

The Pump Runtime Indicator shows how long the pump’s motor has operated since its installation. Toaccess the Pump Runtime Meter, perform the following actions:

1. Remove 12V power from the pump and ensure the Water Sensor switch is in the "Off" position2. Place the Water Sensor switch in the "On" position3. The Green LED will turn on and stay solid for one second, then will blink a number of timescorresponding to how long the motor has been run. The LED will then turn off and a long pause willfollow. See table below to determine the approximate hours of operation based on the correspondingnumber of blinks.4. Once the long pause is complete, normal Water Sensor operation will resume.

“Two blink” amber light Dead battery – the 12-voltpower source has droppedbelow 10.5 volts.

Pump operation locked out.Connect to fully charged batteryor replace your 9v battery.Disconnect/reconnect 12v plugto reset error.

“Three blink” amber light Communication error Contact QED. There is a wiringissue.

“Four blink” amber light Communication error Contact QED. There is a wiringissue.

Pump is flowing only a smallamount of water (~100 mL/min)or is not flowing at all regardlessof Speed Control position

Your pump could be air locked Turn the speed control knobback to off and pause for a fewseconds. Turn it to a “10o’clock” or low speed positionand allow the pump to run for atleast 15 seconds. Placedischarge tube in a container ofclean water to confirm water isbeing pumped (See Step 10).After the 15 seconds andconfirmed pumping, you canslowly increase the speed knobto the desired position

I completed the stepsimmediately above and mypump is still not producing theexpected flow

Your inlet screen could beclogged with sediment/debris

Remove the inlet screen housing(see Step 13) using a screwdriver. Remove the screen usingID snap ring pliers and clean orreplace the screen.

16

SYMPTOM WHAT IT MEANS WHAT YOU SHOULD DO

My filter is clean but I am stillnot seeing the expected amountof flow.

Your impeller may be restricted Remove the inlet screen housing(Step 13), remove the inlet andinlet O-ring (Step 17) andremove the impeller using the IDsnap ring pliers if need be.Inspect the fins and clean theimpeller of any debris, or replaceif necessary. Inspect theimpeller chamber and flush outany debris. Reassemble,ensuring the ‘donut’ on theimpeller is facing you wheninstalled.

There is a constantly blinkingamber light

Your motor chamber has flooded You can continue to operate thepump to complete your samplingoperation, but your motormodule should be replaced assoon as possible. Note that usingthe pump in another well couldrisk cross-contamination ofsamples or wells if the floodedmotor module should leak.Contact QED for assistance.

I cannot reduce my flow rate lowenough to collect samples.

The head pressure against thepump is very low.

Reducing the tubing diametercan increase the head pressure,making it easier to get a steadylow flow rate. Tubing diametersdown to ¼” (6mm) OD can beused.

Pump does not run with a knowngood 12V battery connected.

You may have a blown fuse(located on the control panelinside the reel hub) if the batteryclamps were connected inreverse.

With 12V battery connected,turn water sensor switch to OFF.If the green light turns off, thefuse is blown. Remove the twothumb screws from the face ofthe reel. Remove control boardfrom its pocket. Remove coverfrom fuse holder. Replace fuse ifthere is no conductivity.
