Introduction
Overview
The Veeder-Root HydrX system has been designed to help maintain diesel underground storage tanks (UST) and
their fuel contents in optimal condition by continuously removing water as well as filtering fuel. As the HydrX
system is removing water, it is preventing the establishment of an environment that supports the development of
bacterial colonies that, left unchecked, will foul fueling system components, such as, check valves, shear valves,
filters and nozzles causing equipment down time and loss of business. The bacteria that thrive in these very
specific conditions, where they access nutrients from fuel at the fuel water interface, will also create acids in the
UST that contribute to corrosion and possible long-term failure of fueling system components, including,
submersible turbine pump (STP) columns, shear valves or other ferrous components within the fueling system.
Along with direct water removal, the HydrX system provides a multi-stage filtration system and provides a means
for continuous “polishing” of the UST fuel contents. The multi-stage filters provide a combined 25-micron (um)
particle filter with a coalescing element that separates any entrained water from the fuel. In addition, a second
element provides a fine water separation as well as another 25-micron (um) filtration barrier. This second stage
prevents any possibility of returning emulsified fuel and water back to the UST. A novel water intake device (WID)
provides direct access to water at the tank bottom at it’s farthest reaches. As water is removed from the tank
bottom, only clean fuel is returned through the multi-stage filtering. The unique configuration of the WID and
filtering provides long life for the filter element as well as providing the cleanest, “driest” fuel that protects the
critical flash point and cetane rating of the fuel product necessary for today’s high performance diesel engines.
The HydrX system is comprised of several components that operate together to provide optimal water removal and
intelligent pump control while minimizing impact to site operations. Intelligent pump control continuously monitors
the HydrX system and determines the best strategy for water removal while managing the STP to minimize run time
while providing the required time to remove water and clean fuel in the UST. In addition, the intelligent pump
control prioritizes line and tank testing to maintain site compliance. If water is not collected over the course of a
daily auto run cycle, the HydrX system will halt processing until a new delivery into the tank occurs. HydrX
components include:
• TLS-450 Plus Automatic Tank Gage (ATG)
• HydrX Fuel Conditioner Controller (FCC)
• HydrX Fuel Conditioner (FC)
• Water Intake Device (WID)
• Guide Tube and Guide Tube Riser

Introduction Overview
2
The HydrX Fuel Conditioning Controller (FCC) is installed in a non-hazardous location and it operates in
combination with a TLS-450PLUS Automatic Tank Gauge (ATG) using existing USM interfaces to Veeder-Root
protocol digital devices as well as switched pump control via UIOM relays (see Figure 1).
This setup manual assumes the FCC is installed and wired both to the TLS-450PLUS and the HydrX Fuel
Conditioner according to the instructions in the HydrX Installation Manual 577014-446.
Figure 1. HydrX Fuel Conditioning Controller Front Display
The FCC display has a touch screen which is used to enter HydrX setup parameters, view operating status,
manually initiate system tasks, and check system history logs. The FCC display home screen is shown in Figure 2.
Figure 2. FCC Display Home Screen

FCC Setup
Touch the Setup button on the Home screen to begin the FCC setup procedure and display the Auto Run Time
screen (see Figure 3).
Auto Run Time Overview
Auto Run Time is a user adjustable setting that tells the FCC which hours the HydrX can run the STP and is
typically programmed for quiet hours or overnight shutdowns when sales are slow, or a site is closed for business.
The FCC only runs for the duration of the programmed start and end hours if water is being
removed or if fuel is being circulated through the Fuel Conditioner.
If water extraction and any required fuel circulation ends before the programmed Auto Run end time, the FCC
automatically shuts down the pump and goes into an idle state.
Auto Run Time Setup
1. Touch the Setup button on the Home screen to display the Auto Run Time screen (see Figure 3).
Figure 3. Auto Run Time Screen
2. Touch the Start Hour field to display the number keypad and enter the hour (24 hour format) you wish to start
the HydrX Auto Run Time. To start the FCC auto cycle at midnight, program this value to 00 hour and 00
minute. Start time can be any value between 00 hour 00 minute and 23 hour 59 minute.
Figure 4. Data Entry
3. To use the keypad, touch a number to enter that value. Touch CLR to clear a field’s entry, touch CAN to cancel
a keypad selection, and touch ENT to enter a keypad selection into the associated field and close the keypad.

4. Touch the Start Minute field and enter the minutes of the Start Hour, e.g., 00.
5. Touch the End Hour field to program the FCC ending hour in 24 hour format.
6. Touch the End Minute field and enter the minutes of the FCC ending hour.
Cycle Time Parameters Overview
The Cycle Time and Conditioner Processing Cycle parameters described below include
typical, recommended or required settings. These parameters should initially be set as
outlined below and modified only after observing site operations and the HydrX systems
water loading behavior and fuel quality. While highly configurable for any unique site
conditions or operating requirements, the values below will provide acceptable performance
in most circumstances while balancing STP running hours. Reducing run time, while lowering
the utilization of the STP, can reduce water extraction efficiency. Conversely, more water can
be removed or more fuel can be polished at the expense of running the STP.
Cycle Time Parameters determine how long each operating sequence in the FCC runs. All Cycle Time Parameters
are user settable and break down into four discreet settings: Fill Time, Sweep Time, Vacuum Time and Polish Time.
Cycle Time Parameters Screen
1. Touch the Next button to display the Cycle Time Parameters screen (see Figure 6).
Figure 6. Cycle Time Parameters Screen
2. Fill Time - is the amount of time used to fill the fuel conditioner (FC) after a system has been installed or the
filters have been serviced. This cycle fills the FC with clean fuel that is fed from the STP through the inlet filter.
The inlet filter is a two-stage cartridge type that contains a particle and coalescing element that can separate
entrained water. Fill time is typically set to 15 minutes.
3. Sweep Time - is used to reverse flow through the WID by using pressure from the STP to push fuel to the
bottom of the tank. This pushes any standing water towards the lowest point in the tank for more efficient pick

up as well as clearing any potential clogs that may have built up from vacuuming the tank bottom. This is
typically set to 2 minutes.
4. Vacuum Time - is the amount of time used to vacuum from the bottom of the UST. This is the primary means
for extracting water from the tank. A vacuum cycle is also run at the completion of the fill cycle to remove any
trapped air from the fuel conditioner housing. Typically set to 15 minutes.
5. Polish Time - is the amount of time that the user allows for circulating fuel through the FC. Polishing simply
recycles fuel from the UST at a rate of approximately 6 gallons per minute (gpm) or 360 gallons per hour
(gph). Any entrained water and fine water droplets are continuously separated from the fuel in this process as
well as any particulate or contamination down to 25 micron (um) in size. Polish time is typically set to 4 hours,
however, this value can be increased or decreased to balance STP run time against a site operator’s specific
needs for fuel cleanliness.
Conditioner Tank Settings Screen
Conditioner Tank Settings provide information to the FCC needed to control the maximum drain time (spill
protection) for the auto drain function as well as holding capacity and height to volume conversion. For a typical 5
gallon capacity fuel conditioner, the following parameters should be used, however, these are modifiable for future
FC variations.
1. Touch the Next button to display the Conditioner Tank Settings screen (see Figure 7).
Figure 7. Conditioner Tank Settings Screen
2. Drain Time - is the maximum time the STP is allowed to run if the FC measuring probe doesn’t reach a 0
gallon, minimum, drain. This prevents the pump from running excessively to help avoid spills or accidental
discharges if a drain out is not completed, for any reason. Touch the Drain Time field and select the time in
minutes to drain the FC tank, This should be set to 10 minutes, maximum, for the 5 gallon FC.
3. Extended Drain - is a fine adjustment that lets the drain extend briefly to allow water to clear below the FC
measuring probe’s lower detection limit of 0.75”. Touch the Extended Drain field to select an extra amount of
time in seconds to continue the draining process. Default is 0 seconds.
Unlike the drain time, which shuts down the pump once the water level reaches 0”, this
setting allows the pump to run the programmed amount of time after the water float has
touched bottom on the HydrX Fuel Conditioner (FC) tank. This setting should be limited to 30
seconds, maximum, to prevent any possibility of spilling fuel or ejecting excessive amounts
of fuel into the waste water.
4. Tank Volume - is the maximum volume of water that the FC tank can hold before indicating that a drain out is
required. For the 5 gallon capacity FC, this cannot exceed 5 gallons, however, could be lower if the site
operator chooses. Touch the Tank Volume field and enter an FC tank max volume, typically set to 5.00
gallons.
5. Volume/Inch - is the height to volume conversion used by the FCC for the 5 gallon tank in the Fuel
Conditioner. Touch the Volume/Inch field and enter the required value of 0.3536 gallons per inch (with 5
gallons in the FC tank, the water height measured in the tank will be 14.14”).

FCC Setup Conditioner Processing Cycles Overview
6
Conditioner Processing Cycles Overview
Conditioner Processing Cycles are FCC settings that limit the number of times the FCC runs the STP for water
extraction in it’s different operating modes as described below.
Conditioner Processing Cycles Screen
1. Touch the Next button to display the Conditioner Processing Cycles screen (see Figure 8).
Figure 8. Conditioner Processing Cycles Screen
2. Low Water Cycles - limits the number of vacuum cycles used by the FCC to determine that water is not
being extracted when the FC measuring probe float is below it’s 0.75” minimum detection limit and the float is
resting on the FC tank bottom. This is typically set to 4 cycles and typically higher than Water Cycles limit
used when the float is off the FC tank bottom. See Water Cycles below.
3. Water Cycles - limits the number of vacuum cycles used by the FCC to determine that water is not being
extracted when the FC measuring probe float is above it’s 0.75” minimum detection limit and the float is off the
FC tank bottom. This is typically set to 2 cycles.
4. Sweep Cycles - limits the number sweeps intended to move any standing water along the tank bottom to the
lowest point. Sweeping improves the overall water collection efficiency of the HydrX FC by encouraging water
to move to the end vacuum point that is optimized for water extraction as well as keeping the lines clear from
debris buildup in the WID. This is typically set to 2 cycles. A Sweep cycle combines a sweep period, as
programmed by the sweep time parameter, with a vacuum period, as programmed by the vacuum time
parameter. The combined sweep and vacuum intervals count as a single sweep cycle.
5. Min Water Change - provides the minimum height change in the FC measuring probe’s water float. If the
water float does not meet this minimum change criteria, the FCC logic will determine that water is not being
extracted and will move on to the next cycle or mode. This is typically set to 0.05”.
This does not prevent the FCC from accumulating the water measurement, it only provides a
minimum water detection threshold for the operating logic of the controller to limit STP run
time if water is not being removed from the UST. The water measurement calculator in the
FCC accumulates all the water removed from UST independent of these settings or state of
the HydrX operation.

FCC Setup Filter End of Life (EOL) Overview
7
Filter End of Life (EOL) Overview
Filter End of Life (EOL) Settings tell the HydrX FCC the maximum pressure drop (loss) across each filter element as
well as when to signal the user that a filter change is required based on percent life remaining. An increasing pres-
sure drop indicates loss of flow through the filter due to element clogging. HydrX filters have high surface area, long
life elements. Due to cost and disruption caused by element servicing, filter replacement kits include both inlet and
outlet filters which should be replaced at the same time.
Filter EOL (End of Life) Notes:
1. Filters should always be replaced in pairs followed by a Fill Cycle to maximize performance and minimize risk
of reduced water removal protection.
2. Inlet and Outlet Life Pressure settings should not exceed 10 PSI. While it is possible to set them lower, this
would result in earlier, or more frequent, service calls.
3. To avoid reduced or lost performance caused by loss of flow into the HydrX Fuel Conditioner, the Inlet End of
Life recommended setting is 5%. Technically, this can be set to 0%, however, the amount of time between a
remaining life of 5% and 0% is not material with respect to the cost of the filter replacement or potential loss
of protection.
4. To avoid reduced or lost performance caused by loss of vacuum in the HydrX Fuel Conditioner, the Outlet End
of Life recommended setting is 5%. Technically, this can be set to 0%, however, the amount of time between a
remaining life of 5% and 0% is not material with respect to the cost of the filter replacement or potential loss
of protection.
Filter EOL Settings Screen
1. Touch the Next button to display the Filter EOL Settings screen (see Figure 9).
Figure 9. Filter EOL Settings Screen
2. Inlet Life Pressure - is the maximum pressure drop (loss) across the inlet filter element at the end of its
working capacity. For the filter types used in the HydrX FC, this is set to 10 psi, maximum.
3. Outlet Life Pressure - is the maximum pressure drop (loss) across the outlet filter element at the end of its
working capacity. For the filter types used in the HydrX FC, this is 10 psi, maximum.
At the start of a new system or after filter replacement, at vacuum pressures lower than -3 psi,
the HydrX FC will begin to auto adjust (reduce) the filter life to compensate for the minimum
pressure limit of the HydrX vacuum element.
4. Inlet End of Life - is the percentage value of remaining filter life that the HydrX will signal the user that the
inlet filter must be replaced. This is typically set to 5% to prevent any possibility of contamination or system
degradation caused by completely clogged filter elements.
5. Outlet End of Life - is the percentage value of remaining filter life that the HydrX will signal the user that the
outlet filter must be replaced. This is typically set to 5% to prevent any possibility of contamination or system
degradation caused by completely clogged filter elements.

FCC Setup ATG Device Mapping Overview
8
ATG Device Mapping Overview
ATG Device Mapping Tells the HydrX FCC about the physical locations of the devices within the TLS ATG. As
probes, sensors and the Fuel Conditioner, they are assigned physical locations, like probe 1, probe 2, LPR 1, LPR
2, Fuel Conditioner 1, etc. This section defines where to locate the devices used by the FCC when communicating
with the TLS and inquiring device data.
ATG Device Mapping Screen
1. Touch the Next button to display the ATG Device Mapping screen (see Figure 10).
Figure 10. ATG Device Mapping Screen
2. Fuel Conditioner # - For currently supported single HydrX Fuel Conditioner configurations, this should be
programmed to 1.
3. FC Probe # - is the probe located in the fuel conditioner housing and is the same number as programmed
into the TLS when configuring the FC devices and settings. If the fuel conditioner probe is mapped into the
TLS as the eighth probe and then assigned to the FC during setup, this value would be programmed as 8.
Reference “TLS-450PLUS Setup” for detailed programming instructions.

Service
The HydrX FCC includes service mode screens that support maintenance, operations and diagnostics for
performance monitoring or servicing the system. Principle service controls and indicators are described in this
section.
FCC Service Home Screen
Touch the Service button on the FCC Home Screen to display the Service main screen (see Figure 11).
Figure 11. FCC Service Home Screen
New Filter Button
When a system is first started, after installation and connection to the STP, or after the filters are replaced,
touching the New Filter button refills the Fuel Conditioner (FC) tank with fuel. A fill cycle includes the time
programmed as Fill Time followed by a vacuum interval, programmed as Vacuum Time to completely fill and de-
aerate the tank. During the fill cycle, the inlet and outlet filter pressure losses are independently measured and
stored as reference values that are used to calculate filter life. Inlet filter pressure is measured during the
pressurized interval, essentially at pump pressure. Outlet filter pressure is measured during the vacuum interval
under a vacuum created by an integral venturi element in the HydrX Fuel Conditioner (FC) manifold. As the filters
accumulate debris and clog, the pressure changes from this reference value, the pressure difference indicating
remaining filter life.
Fill Cycle Notes:
1. A complete fill cycle consists of a pressurized fill interval, time determined by programmed fill time, plus a
vacuum interval, time determined by programmed vacuum time. Assuming a typical 15 minute fill time
plus typical 15 minute vacuum time, total fill interval is 30 minutes.
2. Only run a fill cycle during initial system startup or after filter replacement. Reference pressure
measurements are made on the inlet and outlet filter that provide the basis for calculating filter life. Running
fill cycles on used filters, will create significant life calculation errors and degraded system
performance.

Service FCC Service Home Screen

Auto Cycle Button
By pressing the auto cycle button on the front panel of the FCC, if an auto cycle is not already in progress, the
HydrX FCC will run an auto cycle.
Auto Cycle Notes
1. Except for new system startup, an auto cycle is run when the following conditions are met:
a. Water has been collected in the previous day. And,
b. The FCC is within the auto start and auto end times. Or,
c. A delivery has occurred. And,
d. The FCC is within the auto start and auto end times. Or,
e. An auto cycle can also be manually started and will run provided conditions A or C are true.
2. An auto cycle is always run after initial system startup without regard to any prior water removal.
3. Any auto cycle interval is held pending due to any of the following conditions:
a. A line test is in progress
b. A tank leak test is in progress
c. A delivery is in progress and the HydrX is running a delivery polish cycle
4. An auto cycle will not run due to any of the following conditions:
a. The HydrX Fuel Conditioner (FC) requires a water drain service
b. The HydrX Fuel Conditioner (FC) requires a filter service
c. A line test shutdown on the line assigned to the fuel conditioner
d. A tank test shutdown on the tank assigned to the fuel conditioner
e. A line LPR fault on the line assigned to the fuel conditioner
f. A tank probe fault on the tank assigned to the fuel conditioner
g. A communication failure between the FCC and ATG
h. Failure of any FC sensor (either probe or pressure sensor)
5. Auto cycle always starts with vacuum cycles, followed by sweep cycles, followed by polish cycles. The rules
for vacuum and sweep cycles are defined in notes 5 - 7 below.
6. The Low Water Cycles setting is the number of consecutive vacuum cycles without water removal when the
HydrX Fuel Conditioner (FC) float is on the bottom of the FC tank.
7. The Water Cycles setting is the number of consecutive vacuum cycles without water removal when the HydrX
Fuel Conditioner (FC) float is not on the bottom of the FC tank.
8. The Sweep Cycles setting is the number of consecutive combined sweep and vacuum cycles without water
removal after the FCC has completed vacuum only cycles.
9. For the cycle types defined by notes 5 – 7, the counter value decrements when water is not extracted. If water
is extracted, the counter does not decrement or is reset to it’s programmed setting until the consecutive
number of cycles are run without water removal.
Auto Drain
This function automatically operates the STP to eject water from the FC housing via a Veeder-Root 330020-880
Water Drain Kit, or similar. After coupling the kit to the FC, the user touches the FCC Auto Drain button (see
Figure 11) to initiate the FC tank drain sequence. The 330020-880 kit includes a nozzle to control the flow out of
the FC. The FCC continuously monitors the water level in the FC housing and, once the water float reaches the FC
tank bottom, or the programmed Drain Time has expired, automatically shuts down the STP.

Service Filter Performance Screen
11
Filter Performance Screen
The Filter Performance screen displays the read-only FC inlet and outlet valve status (see Figure 12). ‘P0’ is the
pressure measured by the HydrX FCC when a filter is new or has been replaced. ‘P’ is the current pressure as
measured by the HydrX FCC that indicates if the filter is clogging which diminishes filter life. ‘%’ is the percent of
remaining filter life. This screen displays all relevant filter information, including:
• Inlet and Outlet filter reference pressures, P0. This is the pressure measured through the filter at initial system
startup or after filter replacement and represents the filter pressure at 100% capacity or life.
• Inlet and Outlet filter current operating pressure, or P. The reference pressure, P0, for each filter minus the
current operating pressure is the pressure drop that coinciding with the programmed filter parameters, Inlet Life
Pressure and Outlet Life Pressure, respectively.
• Inlet and Outlet filter percent remaining life (%). This value is the calculated remaining life on each filter and is
calculated as:
% = (Po  P) / (Programmed Life Pressure) x 100
A replace filter service signal is sent to the TLS once the percent remaining life is less than or
equal to the programmed Inlet or Outlet End of Life setting. For example, if the FCC is
programmed to signal at 5% life remaining, when the inlet or outlet filter calculation result is
5%, or less, the filter replacement signal is set.

2. Touch the Next button to display the next service screen.
Water Collection Screen
The HydrX FCC accumulates a set of water collection statistics to help users understand the conditions when
water is entering or collecting in their UST. Statistics are arranged in the following groups:
• Current and Last Hour accumulation, Current and Last Day accumulation (see Figure 13).
Figure 13. Water Collection (Hour/Day) Screen

Service Service Counter Screen

Monitoring patterns in these distributions can help users identify if water is collected in gradual condensing
type conditions, dropped with deliveries, i.e., correlating daily accumulations to ATG deliveries or ingress after
wet weather periods in either daily or monthly accumulations.
Touch the Clear button to reset the accumulations to zero.
Service Counter Screen
The FCC includes non-resettable service counters that count water drain outs and filter changes (see Figure 15).
Figure 15. Service Counters Screen
Operational Mode History Screen
The FCC maintains a running history of both the number of times and the amount of time the system has been in
each of its operational modes (see Figure 16). Time and counter values are reset at the start of an Auto Cycle.

FCC Software Upgrade
To avoid electric shock do not touch any wiring terminals inside the FCC while
performing this procedure.
1. If you have a FCC upgrade thumb drive with the software upgrade already on it, go to Step 3.
2. If you have downloaded the FCC software onto a PC, insert a thumb drive into your PC and copy the
HGDATA01 directory from your PC location to the root directory of the thumb drive (typically drive labeled D:).
The USB is formatted as FAT32, so, your PC operating system must support the FAT32 file
system to copy this file. Newer versions of MAC OS support this, but you should make certain
if you are copying from a MAC. Specify that it is OK to overwrite the contents.
3. Open the door of the FCC and with the power to the FCC On, plug the upgrade thumb drive into the FCC
USB2 port on the rear of the FCC Display (see Figure 22).
Figure 22. FCC USB Ports
4. When the Confirmation screen displays, touch the Download Proj. button to install the software upgrade
(see Figure 23).
