Chapter 1: System Description
Function and Theory
The Geocontrol PRO is a unique controller for operating down well bladder type
sampling pumps. When an external 12 VDC power source is connected to the controller,
the internal air compressor is capable of producing a pressure of 100 psi. This pressure
allows the user to take samples from a depth to 180ft.
The controller offers a variable cycle timer for controlling the portable compressor’s on-
time and off-time. While the compressor is on, air is pushed down well to the bladder
pump, compressing the internal bladder and evacuating the liquid in the pump. When the
compressor shuts off, the air pressure in the pump exhausts out of the system, allowing
liquids to enter the pump.

Chapter 2: System Installation
WARNING
Verify the 12V system to be used is rated and fuse protected for operation at 15 amps
continuous operation. Failure to verify system rating could result in damage to
equipment. Over-heated wiring and other materials or components in contact or near by
the power delivery system could pose a potential fire or burn hazard.
To operate the Geocontrol PRO, make sure the power switch is in the
“off “position (rocker in down position). Plug the power input cord into a fuse protected
12V lighter receptacle on a negatively grounded system. If the controller is to be wired
directly to a 12V battery, make sure to connect the positive (red) alligator clip to the
positive (red) battery terminal and connect the negative (black) alligator clip to the
negative (black) battery terminal. Next, securely plug in the circular plug connector on
the opposite end of the cable to the corresponding receptacle on the face of the
controller. Continue by plugging the pump’s air hose into the port labeled AIR on the
controller’s face. Then plumb the pump’s discharge line into a suitable container. Check
all wiring and plumbing for correctness.

Finally, double check to ensure the 12V system positive and negative is not reversed at
any connection point.

WARNING
Do not operate this equipment if it has visible signs of significant physical damage other
than normal wear and tear.
Chapter 3: System Operation
CAUTION
Operating the equipment in any way other than that described within this document
could potentially damage the equipment.
CAUTION
Disconnect power source when not in use.
Double check 12V system positive and negative are not reversed at any connection
point.
Before turning the power switch “on” turn the Geocontrol PRO’s “Fill” and “Discharge”
timer knobs to adjust the cycle times. These knobs are located on the front face of the
Geocontrol Pro below the airline pressure gauge. To the left is Discharge time and to the
right is Fill time. Use the radial number scales around each timer knob to adjust timer
values in seconds.
Discharge Time:
The time it takes to squeeze the bladder and push the water out of the pump. Increase this
time with increased depth to water and larger bladder pumps. Decrease this time with lower
depth to water and smaller bladder pumps. Timer can be set from approximately 2 to 60
seconds.
Fill Time:
The time allowed for the bladder to refill. Increase this time with increased depth to water and
larger bladder pumps. Decrease this time with lower depth to water and smaller bladder
pumps. Timer can be set from approximately 2 to 60 seconds. Fill rate depends on
hydrostatic pressure (pressure from the water above the pump) and will vary depending on
pump placement within the water column. Therefore, the more water above the pump the
faster it will fill.
Turn the controller power switch ON. In case of long fluid discharge lines it could take
multiple cycles for water to reach the outlet. If the fluid discharge from the pump falls off
before the discharge cycle is complete, the discharge time is set too high. This could
result in a creased bladder that will reduce per cycle pump volumes. Therefore, if the

9

compressor is still running and water has stopped coming out of the discharge tube, the
discharge time should be decreased. Pumping efficiency can be maximized by
measuring the amount of fluid discharged. If the volume of fluid after one pump cycle is
less than the rated volume of the pump being used, then the fill rate can be increased.
The air line pressure gauge can be utilized to maximize efficiency. As a general rule, the
pressure indicated on the gauge should not exceed an equivalent depth to water
pressure. 1PSI = 2.31 Feet of water. Once the bladder in the pump is empty of liquids
the pressure will increase sharply. If a quick pressure increase is noticed, reduce the
discharge time until the quick pressure increase is no longer obvious.
For example, if the well you are sampling has a depth to water of 23 feet you should not
expect to see a reading on the pressure gauge much over 10 PSI. When the discharge
cycle begins the reading on the pressure gauge will begin to rise. Once depth to water
pressure has been reached the reading will ‘stall’ at that pressure until the bladder is
empty or discharged. Once the bladder is compressed completely the pressure will
again start to rise. For maximum per cycle liquid pumping volume, this is the optimum
point at which the discharge timer would expire and the fill rate timer would begin.
Reduced per cycle liquid pumping volume can be achieved by further decreasing the
discharge time, thus evacuating only part of the total bladder volume.
CAUTION
For use with negative (-) ground systems only.
Exceeding the recommended duty cycle will cause overheating.
Damage will result if the supply voltage exceeds 14 VDC.

Maintenance Procedures
Disconnect power source when not in use.
Unit must be returned to Geotech for any service. In order to ensure a long service life,
keep the Geocontrol PRO clean. Often a soft, damp cloth can be used to remove dust
and dirt from the exterior surfaces of the Geocontrol Pro. In extreme cases, or to remove
aged caked on dirt and dust, a mild soap and water solution can be applied to a soft
cloth and used to clean the exterior surfaces of the Geocontrol Pro. Do not soak or
directly spray liquids on the Geocontrol PRO.
Equipment can be repaired by factory trained repair technicians only. Improper repair of
equipment may result in degradation of performance and/or service life. Disassembly
exposes potentially dangerous moving components that could injure someone who is not
properly trained to repair this equipment.

Chapter 5: System Troubleshooting
The Geocontrol PRO has been designed and manufactured to provide a long service life
and trouble free operation in the field. If the compressor, during charge cycles, becomes
sluggish, check supply voltage. If the supply voltage falls below 12 VDC, the
compressor’s performance will be directly affected. A fully charged battery will produce
the best results.
Other sources of low pump output may be the 12V lighter receptacles or plugs. Make
certain these connections are securely plugged in and is clear of any debris. Once
securely plugged in, rotating the connection can often help if there is a dead spot in the
connector. Also, check for connection and cable fatigue, cracks, rust etc.
If the compressor does not turn on:
•Double check battery polarity is correct. In other words, the positive and negative
cables are connected positive to positive and negative to negative. Failure to do
so will likely cause the 15 amp circuit breaker to trip. If it has been tripped, it
must be reset by pushing the white button marked with ‘15’ in red on the front of
the GeoControl Pro. Furthermore, this is a thermally activated, over current
protection device. If it has been tripped numerous times in rapid succession it will
require some time to cool down prior to attempting to restart the pump. The
amount of time will depend on ambient air conditions and the temperature of the
circuit breaker.
•Turn the power switch to the OFF position and let the unit sit in the OFF state for
two minutes. This will hard reset the electronic timer module.
•If ambient temperatures are in excess of 104°F (~40°C) then disconnect from
power and let sit in a cool location. Do not open the case for any reason. This will
not hasten the cooling process, but will invite debris into internal components that
could result in reduced life or immediate equipment failure.
•If the compressor still does not turn on the electronic timer module may have
failed. Call Geotech at 1-800-833-7958 to arrange for the equipment to be sent
back to a factory authorized repair location.
Compressor turns on and fluid is being pumped but no pressure is indicated on
the gauge.
•The pressure gauge has failed; however operation of the device may continue
even though the gauge feature is not operational. Call Geotech at 1-800-833-
7958 to arrange for the equipment to be sent back to a factory authorized repair
location.
Fluid is not being pumped and the compressor turns on, no pressure is indicated
on the gauge.
•Remove the air line from the front of the Geocontrol Pro. Block the air outlet on
the front of the Geocontrol Pro while the compressor is running to verify the
pressure gauge needle indicates an increase in pressure. Remove the blockage
from the air outlet and observe whether or not a small burst of compressed air is
released. If pressure cannot be built at the outlet on the front of the Geocontrol
Pro, call Geotech at 1-800-833-7958 to arrange for the equipment to be sent
back to a factory authorized repair location.
•If pressure can be built at the air outlet on the front of the Geocontrol Pro while
the compressor is running:

12

oAttach the air line only and block the end. Verify the pressure gauge
needle indicates an increase in pressure. Remove the blockage from the
end of the air line and observe whether or not a small burst of
compressed air is released. If pressure cannot be built at the end of the
air line, check the air line for cuts, kinks and holes, especially at, and
near, the bladder pump hose barb or compression fitting connections.
•If pressure can be built at the end of the air line while the compressor is running:
oAttach the airline to the bladder pump. Remove the fluid discharge tube
from the bladder pump. While the compressor is running, very little air
discharge should be felt at the pump discharge fitting. The pressure
gauge on the front of the control pro should indicate a rise in pressure. If
this does not occur and a continuous air flow can still be felt at the pump
fluid discharge fitting, then the bladder, or bladder seal, has been
compromised and should be repaired or replaced. Information on this
procedure can be found in the product manual specific to the bladder
pump being used. Or call 1-800-833-7958 for further assistance.
oReminder: Be careful not to over pressurize and crease the bladder
inside the pump as this will reduce the fluid flow during normal operation.
