Introduction
Welcome to QED Environmental Systems’ AutoPump® (AP4 Ultra 4.0) manual.
To ensure the best operator safety and system performance, it is strongly recommended that the operators read this
entire manual before using the system.
This manual reflects our many years of experience and includes comments and suggestions from our sales and service
personnel and most importantly from our customers. The chapters, their contents and sequence were designed with you,
the user and installer, in mind. We wrote this manual so it can be easily understood by users who may not be familiar with
systems of this type or are using a QED system for the first time.
Safety
Safety has been a cornerstone of our design which has been proven out in building and shipping systems throughout the
world. Our high level of performance is achieved by using quality components, building in redundancies or backup
systems, and not compromising our commitment to quality manufacturing. The net result is the highest quality and safest
pneumatic pump recovery system on the market. We feel so strongly about safety, based on years of working with the
hydrocarbon industry, that it is the first section of all our manuals

Chapter 1: Safety
Safety has been a prime consideration when designing the AutoPump System. Safety guidelines are provided in
this manual, and the AutoPump System safety features are listed below. Please do not attempt to circumvent the
safety features of this system.
We have also listed some possible hazards involved when applying this system to site remediation. Nothing will
protect you as much as understanding the system, the site at which it is being used, and the careful handling of
all equipment and fluids. If you have any questions, please contact the QED Service Department for guidance.
As you read through this manual, you will encounter three kinds of warnings. The following examples indicate
how they appear and lists their respective purposes.
Note: Highlights information of interest.
Caution: Highlights ways to avoid damaging equipment.
Warning: Highlights personal safety issues.
A Partial List of Safety Procedures
WARNING: The air compressor and any other electrical equipment used with this pneumatic system must be
positioned outside of any area considered hazardous because of possible combustible materials.
These safety procedures should be followed at all times when operating QED equipment on or off site, and should be
considered as warnings:
• Wear safety goggles when working with the AutoPump System to protect eyes from any splashing or pressure
release.
• Wear chemically resistant rubber gloves, boots, and coveralls when handling the AutoPump and fluid discharge
hose to avoid skin contact with the fluid being removed
• Point tubing/hoses away from personnel and equipment when connecting or disconnecting.
• Always ensure that the fluid discharge line is connected before the air line to prevent accidental discharge.
The AutoPump System minimizes the potential for accidents with the following safeguards:
Fire and Explosion Protection
Almost all of QED underground fluid extraction systems are pneumatic. This offers many inherent fire and explosion
protection features.

Chapter 3: Overview
The AutoPump® fills and empties automatically, and is very easy to install, use, and maintain.
The AutoPump is a pneumatic fluid extraction pump that pumps in pulses. It handles any liquid which flows freely into the
pump and is compatible with the component materials and with the connecting hoses. The AP Ultra is intended for vertical
operation in well casings with a 3.75-inch(9.53cm) or greater internal diameter. It can pump particles up to 1/8-inch in
diameter.
The AutoPump is very versatile and available in a wide range of lengths, valve arrangements, and materials of
construction to meet particular site specifications.
Equipment will vary by application and site specifications. (See Chapter 3)
General Specifications
3.6 inch (91 mm)
5 - 120 psi (0.4 - 8.5 Kg/cm2)
5 - 200 psi (0.4 - 14.1 Kg/cm2)
0-14 gallons per minute (0-53 liters per minute)
This is How it Works
The AutoPump is a submersible compressed air-driven pump which fills and empties automatically. It also controls
the fluid level in a well automatically. The pump fills (See Figure 3) when fluids enter either the top or bottom check
valve. Air in the pump chamber exits through the exhaust valve as the fluid fills the pump. The float inside the pump is
carried upwards by the fluids rising in the casing until it pushes against a stop on the control rod, forcing the valve
mechanism to switch to the discharge mode.
The switching of the valve causes the exhaust valve to close and the air inlet valve to open. This causes the pump to
empty (see Figure 3) by allowing compressed air to enter the pump. This pressure on the fluid closes the inlet check
valve and forces the fluids up the discharge line and out of the pump through the outlet check valve. As the fluid level
falls in the pump, the float moves downward until it pushes against the lower stop on the control rod, forcing the valve
mechanism to switch to the fill mode. The outlet check valve closes and prevents discharged fluids from re-entering
the pump. The filling and discharging of the pump continue automatically.
NOTE: The figures shown here are simplified schematics.

Chapter 4: Equipment
Unpacking
During the unpacking procedure, check for the following:
• All parts on the packing list have been included in the box
• All fitting openings are unobstructed
• The equipment has not been damaged in shipment
Equipment List
The equipment list will vary depending on site specifications, but the following list is a typical configuration
1. Top-Loading or Bottom-Loading AP Ultra with support harness
2. Single stage filter/regulator with:
• 5 Micron filter with auto drain tap
• Pressure regulator with gauge
• Maximum operating pressure 120 P.S.I. (8.4 Kg/cm2)
3. Pump Cycle Counter (PCC)
4. Pump support system:
• Well cap
• Polypropylene support rope with quick-link assembly or SS wire rope
(Alternate materials as required)
Single Stage Filter/Regulator
A single stage 5 Micron particulate air filter/regulator has a manual or an optional automatic drain and is installed
on the system air supply line. The filter/regulator removes particles and water droplets from the air passing to the
AP Ultra.
NOTE: Too much air pressure can result in low pump efficiency

Chapter 5: Installation
1. Cover the pump tubing/hose ends with tape if they are to be pulled through trenches or laid on the
ground. This is to prevent debris from entering the lines.
2. Blow out all water and particles from compressed air conduits (including down well pump air supply lines) and
fluid lines for at least 10 seconds after the water and particles exit before connecting them to the system.
3. Slip clamps over appropriate tubing/hose prior to connecting the tubing/hose to the pump barbs.
4. Push tubing/hose down flush with the fitting's nut if possible; cover at least three barbs if three or more are
present (Note: when installing tubing in freezing weather, tubing can be dipped in warm water for a few seconds
to soften the nylon).
5. Attach pump support rope/cable to the pump. "See figure 7"
6. Attach pump air supply and liquid discharge lines to the well cap. "See Figure 6". Attach the air exhaust line to
the well cap if the pump air is to exhaust outside the well (Note: the liquid discharge line is always the largest
diameter of the three lines, and the air supply line is always the smallest diameter).
7. Connect the pump air supply and liquid discharge lines to the appropriate surface lines/headers.
8. Turn on the air pressure to the pump (minimum of 0.5 psi per foot of vertical static head).
Caution: Submerging the pump before supplying it with air will result in fluid entering the exhaust
tubing/hose. Those fluids will be discharged from the exhaust tubing/hose during the first few cycles of
the pump. If this discharge will not be confined to the well; i.e., if the air exhaust line is routed outside the
well*, it is important to make sure that the air exhaust line is not directed such that equipment/ personnel
could be splashed by the discharged fluid when air is turned on to the pump.
Note: Submerging the pump before supplying it with air can also result in fluid entering the air supply line. This fluid
from the well can contain particles, which could interfere with operation of the pump's air valve.
9. Lower the pump to the desired depth in the well.
10. Secure the pump by tying off the pump support line or by placing the well cap (or flange) on the well.

10
Chapter 5: Installation
11. Increase the air pressure to the pump until the pump is pushing the fluid out at the desired rate. With sufficient air
pressure (at least 10 to 15 psi higher than the vertical static head), the pump will gradually draw down the fluid level in
the well to the level of the pump. The time required for this draw down varies with the yield of the well as compared to
the flow rate of the pump. The maximum recommended pump operating pressure is 120 psi.
Note: If the well environment is such that deposition occurs on stainless steel parts, the operator may wish to raise the
pump above the water level during a shutdown of the system.
* Routing the air exhaust in vacuum wells:
QED controllerless pumps automatically control the liquid level in the well. Under normal conditions, the liquid level will be
maintained at a point approximately one foot below the top of a bottom load pump (this is the pump's actuation point). The
pump will automatically start and stop as needed to maintain the level at this actuation point.
When QED controllerless pumps are used in wells that are under vacuum, and the exhaust air is routed into the well, the
well level will be maintained at this normal actuation point. If, however, the well is under vacuum and the exhaust air is
routed outside of the well (to atmospheric pressure), the actuation point of the pump will be higher than the normal
actuation point by a distance equal to the amount of vacuum applied to the well (expressed in "inches of water column”).
Please note that the pump will still function normally and maintain the liquid level, albeit a higher level.

11
Chapter 5: Installation
Hose Bundles
Hose bundling or the use of jacketed tubing reduces equipment entanglement at the well surface, and aids the removal
of the pump from the well. Bundling also assists in positioning the pump and down-well hose assembly against one
side of the well casing. Maximum space is created for other items, such as probes, to be periodically placed inside the
well.
Follow these instructions to create a hose bundle:
1. Lay the equipment on the ground and make all of the necessary hose connections. (See Figure 4).
2. If a well cap is supplied, install it on the hoses. (See Figure 4).
3. Connect the quick-link assembly on the support rope to the eyebolt on the AP4+ and lay the support rope out along
with the hoses. Make sure that none of the hoses or support ropes are crossing over each other (See Figure 7).
Note: To make the next step easier, pull the support rope and the hoses taut.
4. Starting at the AutoPump end of the hose, put a tie-wrap through the center of the braided support rope just above
the uppermost quick-connect or barb on the AutoPump (See Figure 7).
5. Pulling the rope taut, put the tie-wrap around the fluid discharge hose with the rough surface outwards. Cross the
ends and complete the connect the tie-wrap make sure it is straight and is not kinking the hoses (See Figure 7).
Note: After completing this step, the fluid discharge hose will be attached to the support rope and the exhaust
hose. At this point the air supply hose is still lying free.
6. Place the next tie-wrap two feet towards the well cap from the first. Secure the air supply hose rather than the
exhaust hose.
Note: It is important to put the tie-wraps approximately two feet apart to keep a proper discharge hose/support
rope bundle. Experience has shown that spreading the tie-wraps further apart than two feet increases the
probability for hose kinking.
7. Continue to alternate the air exhaust and the air supply tie-wraps every two feet, stopping about five feet from the
wellhead.
8. Being careful not to leave any sharp edges, cut the excess from the tie-wraps.
You now have a down-well bundled hose assembly that supports both the hoses and the down-well equipment.

Chapter 6: Maintenance
Cleaning the AutoPump Ultra 4.0
Caution: Wear goggles, gloves, and coveralls when servicing this system.
Note: The Ultra 4.0 uses non-stick finishes on the float and discharge tube. To protect these finishes, never
use any type of abrasive pad, wire brush, steel wool or sandpaper to clean these two components.
Removing the Pump’s Casing
1. Disconnect the air supply from the pump.
2. Remove the bolt at the bottom of the pump which holds the inlet screen in place (bottom loading pumps only).
3. Remove the three bolts at the bottom of the pump which hold the inlet in place (See Figures 8 and 9).
4. Remove. the inlet from the pump’s casing by pulling it out.
5. Twist and slide the casing down off the pump’s frame.
Cleaning the Pump Interior
The inner workings of the pump should now be exposed for inspection and cleaning (See Figures 8 and 9 ).
Gently brush off built-up solids from the float, discharge tube, pump casing and control rod.
Mineral Build-up Cleaning Procedure
1. The bottom “spider” casting should be removed by unthreading it from the discharge tube. (See Figures 8 and 9
).
2. Visually inspect the fluid discharge pipe for scale build-up or debris. Also, do the same with the float that slides
up and down on the discharge tube.
3. Should there be scale deposits on either the discharge tube or float, remove the float from the discharge tube as
Follows: (See Figures 8 and 9 ) Remove the small steel hairpin from the bottom spring cup. Removing the
hairpin
and spring cup will allow you to remove the spring, sliding stop and float from the SS discharge pipe.
4. The fluid discharge tube can now be cleaned using a damp cloth. To aid in cleaning, the discharge tube can be
soaked in vinegar. To remove tougher build-up, scour pads that are made for non-stick cookware can be used.
5. Both the internal and external surfaces of the float can be cleaned using a damp cloth. To aid in cleaning, the
float can be soaked in vinegar. To remove tougher build-up, scour pads that are made for non-stick cookware
can be used. The float end plates can be removed to ease cleaning. After cleaning, the plates should be
replaced on the same end of the float from which they came.
6. The white plastic square control rod is the next component to be cleaned. The control rod is the item that
fits through the smaller hole in the float plate and is adjacent to the discharge tube in the assembled
pump. To clean the control rod, use an abrasive pad or a razor or utility knife (not sandpaper).
7. The final component to be cleaned is the outer casing. The fastest and most effective way to clean out
the inside surface of the pump casing is to use a three-stone honing tool. The technique is to move the hone
in and out a half dozen times or so, through each end of the casing. The time for the casing cleaning should
take no longer than 5 minutes.
The AutoPump is now ready for re-assembly by following the steps above in reverse order.
Note: Before threading the bottom “spider” onto the pump’s discharge tube, be sure to wrap the discharge tube’s
threads completely with Teflon tape.
Note: Before inserting the two assemblies back into the pump’s casing, apply PTFE grease to the two o-rings (#16
on the next page) to make the next disassembly easier.
