System Description
Function and Theory
The Geocontrol PROis a unique controller for operating down well bladder type s
a
m
p
lin
g
pumps. When an external 12 VDCpower source is connected to the controller, the internal
air compressor is capable of producing pressure up to 100 PSI
(7
b
a
r
)
. This pressure allows
the user to take samples from a depth to 180’
(
55 m
)
.
The controller offers a variable cycle timer for controlling the portable compressor’s
ON
t
im
e
and OFF time. While the compressor is ON, air is pushed down well to the bladder pump,
c
o
mpressing the internal bladder and evacuating the liquid in the pump. When the
c
o
m
p
r
e
ss
o
r
turns OFF, the air pressure in the pump exhausts out of the system, allowing liquids to enter
the
pump. See Figure 1-1.

battery terminal. Next, securely plug in the circular plug
connector on the opposite end of the cable to the corresponding receptacle
o
nthe face of the
controller. Continue by plugging the pump’s air hose into the port labeled AIR
o
n the controller’s
face. Then plumb the discharge line into a suitable container. Check all wiring and plumbing for
c
o

Before turning the power switch
ON,
turn the Geocontrol PRO’s
FILL TIME
and
DISCHARGE
TIME
knobs to adjust the cycle times. Theseknobs are located on the front
face of the
Ge
o
c
o
n
t
r
o
l PRObelow 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 s
e
c
o
n
d
s.
Discharge
Time
The discharge time is the time it takes to squeeze the bladder and push the water out of the
pump. Increase
t
his time with increased depth to water and larger bladder pumps. Decrease
this time with l
ow
e
r depth to water and smaller bladder pumps. Timer can be set from
approximately 2-75 s
e
c
onds
Fill
Time
The fill time is thetime allowed for the bladder to refill. Increase the fill time with more depth to
water
a
n
d
larger bladder pumps. Decreasethe fill time with less depth to water and smaller
b
l
a
dd
e
r pumps. The timer can be set from approximately 2-75 seconds. Fill rate depends on
hy
d
r
o
s
t
a
t
i
c
pressure
(
p
r
e
ssur
e
from the water above the
p
um
p
)
and varies depending on pump
p
l
a
c
e
ment within the water column; the more water above the pump the faster it will
f
ill.
Turn the controller power switch ON. When using longer fluid discharge lines, it could take
mul
t
i
p
l
e
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
c
r
ea
s
e
d
bladder that will reduce per cycle pump volumes. Therefore, if the compressor is still runnin
g
and water has stopped coming out of the discharge tube, the discharge time should
b
e
decreased. Pumping efficiency can be maximized by measuring the amount of fluid
d
is
c
h
a
r
g
e
d
. If
the volume of fluid after one pump cycle is less than the rated volume of the pump
b
e
in
g
used,
then the fill rate can be in
c
r
ea
s
e
d
.
Do not operate this equipment if it has visible signs of significant physical
damage other

h
a
n normal wear and tear.
Operating the equipment in any way other than that described within this
document

Theair line pressure gauge can be utilized to maximize efficiency. The pressure indicated on the
gauge should not exceed an equivalent depth to water pressure. 1 PSI = 2.31’
(1
bar = 1.02 m
)
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
q
ui
c
k
pressure increase is no
longer
n
o
ti
c
eable.
For example, if the well you are sampling has a depth to water of 23’
(7
m
)
the pressure gauge
may not exceed 10 PSI (.7 bar)
.
When the
d
is
c
h
a
r
g
e
cycle begins the reading on the pressure
gauge will begin to rise. When pressure based on depth to water has been reached the reading
will stabilize at that pressure until the bladder is empty or
d
is
c
h
a
r
g
e
d
. Once the bladder is
compressed completely the pressure will again start to increase. For m
a
x
imum volume per cycle,
this is the optimum point at which the discharge timer
wo
ul
d
expire and the fill rate timer would
begin. To reduce the volume pumped per cycle, decrease the discharge time.
For use with negative

System Troubleshooting
The Geocontrol PROhas been designed and manufactured to provide a long service life
a
n
d
trouble free operation in the field. If the compressor, during charge cycles, slows, check supply
voltage. If the supply voltage falls below 12V, the compressor’s
p
e
r
f
o
rm
a
n
c
e
will be directly
affected. A fully charged battery will produce the best r
e
sul
t
s.
Other sources of low pump output may be 12V lighter receptacles or plugs. Ensure these
connections are securely plugged in and clear of any debris. Once securely plugged in, r
o
t
a
t
in
g
the connection can often help if there is a dead spot in the connector. Also, check for
c
o
nn
e
c
tion
and cable fatigue, cracks, surface oxidation, rust, or other visible damage.
Problem: The compressor does not turn o
n.
Solution
•
Check battery polarity. In other words, the positive and negative cables are connected
positive to positive and negative to negative on the 12V battery. TheGeocontrol PRO
is
p
r
o
t
e
c
t
e
d
from damage due to reverse polarity
c
o
nn
e
c
t
i
o
n.
•
Turn the power switch to the OFFposition and let the unit sit in the OFFstate
for
t
wo
minutes. This will hard reset the electronic timer m
o
d
ul
e
.
•
If ambient temperatures are over 104°F
(
40°C
),
disconnect the compressor from power
and l
e
t
sit in a cool location. Do not open the case for any reason. Opening the case
will expose the internal components to debris that could result in reduced life
o
r
immediate equipment failure.
•
If the compressor still does not turn on the electronic timer module may have

Solution
•
Remove the air line from the front of the Geocontrol PRO. Block the air outlet on the
f
r
o
n
t
of
the Geocontrol PROwhile the compressor is running to verify the pressure gauge needle
indicates an increase in pressure. Remove the blockage from the air outlet and
o
b
s
e
rv
e
whether 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 Service at 1-800-833-7958 to arrange for
the equipment to be sent back to a factory authorized repair l
o
c
a
t
i
o
n.
•
If pressure can be built at the air outlet on the front of the Geocontrol PROwhile the
c
o
m
p
r
e
ssor is runnin
g
o
Attach 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
o
b
s
e
rv
e
whether a small burst of compressed air is released. If pressure
cannot be built
a
t
the end of the air line, check the air line for cuts, kinks and
holes, especially at/nearthe bladder pump hose barb or compression fitting
c
o
nn
e
c
t
i
o
ns.
•
If pressure can be built at the end of the air line while the compressor is runnin
g
:
oAttach the air line to the bladder pump. Remove the fluid discharge tube from the
b
l
a
d
der pump.
oWhile the compressor is running, very little air discharge should be felt at the pump
discharge fitting. Thepressure gauge on the front of the Geocontrol PROshould
indicate a rise in pressure.
oIf this does not occur and a continuous air flow can still be
f
e
l
t
at the pump fluid
discharge fitting, then the bladder, or bladder seal, has been
c
o
m
p
r
o
mised 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 Geotech Service
a
t
1-800-833-7958 for further
a
ssis
t
a
