INTRODUCTION
The ILCS Foamer Control System is the industry’s first foam cleaning system with data management capabilities. Say
“good-bye” to run away truck wash chemical costs that erode profit margins and create undue wear and tear on
vehicle assets. This reliable microprocessor based system records all user activity in real time, and generated useful
management reports in standard text and Excel formats. The system can be programmed and linked to any PC with a
Windows Operating System.
The ILCS Foamer Control System is password protected with 99 programmable user passwords. Data can be stored
for up to 1250 individual user records. The User Interface is intuitive and easy to use. Anyone with a passcode can
use this system with little or no training. Using the ILCS Foamer Control System promotes responsible and safe
usage of wash chemicals while allowing you to better manage your business.
INSTALLATION
See the diagram on the following page for reference to the steps below
(1) Mount the unit in the desired location using applicable hardware (not provided).
(2) Using the metering tip chart below as reference, choose the tip closest to the actual ratio you need. Thread the
metering tip into the barbed end of the appropriate checkvalve. Do this for each chemical used.
(3) Install a foot-strainer on the end of each supply tube. Slide a ceramic weight over each supply tube. Cinch a
plastic tie wrap (provided) around the connection to secure. Insert foot end into chemical container.
(4) Route the chemical lines up through the bottom of the unit and connect to the appropriate checkvalves.
(5) Connect the water supply on the left side of the unit (water pressure min 40 PSI / water temp 140° F max).
(6) Connect the air supply to the 1/4” NPT port on the left side of the unit (system requires a minimum 40 PSI clean,
dry air at 5 – 10 CFM during operation).
(7) Route the discharge hose up through the bottom of the unit and connect to the barb fitting. Secure in place with a
hose clamp.
(8) The ball valve for the wand (foamer nozzle) is shipped disassembled. Attach the ball valve to the discharge end
of the hose, then connect the wand to the ball valve using the provided nipple.
(9) Plug in the power cord to an appropriate 115 VAC outlet.
METERING TIP RATIOS
•The following chart is intended as a guide only. Actual dilution ratios will vary based on product viscosity, tubing
distance, water pressure, and air pressure.
•Choose the tip closest to the actual ratio you need. Be sure to verify the actual chemical to water mixture
dispensed during operation. Change the metering tip if necessary to achieve the correct dilution.

OPERATION
To operate the system, you must first program it either from the built-in programming menus (on the following pages)
or by using the WinReporter PC software. Once all system programming is complete, you will be ready for operation.
Check that all chemical lines are primed and that the water and air supplies are both turned on.
(1) Press Main Power switch to ON position.
(2) Insert the key and turn to the right (key vertical to operate).
(3) Type in your user password and press ENTER — if your password was accepted, the display will flash a brief
acknowledgement and you will then see the following.
(4) Press START. If the display shows “ACCESS RESTRICTED”, the current user is not allowed to operate the
system because they have exceeded their uses for the present shift. Otherwise the system will start running.
(5) The display will show a count down of the remaining time left in the cycle.
(6) Slowly open the ball valve on the discharge hose while holding foam wand away from you.
(7) Turn on the manual valve (counter-clockwise) for the desired product. The valve is open when the handle is
vertical and closed when the handle is horizontal. Spray the target area as needed.
(8) Flush the discharge hose clean with fresh water between products by waiting a few seconds after closing one
manual valve before opening the next.
(9) Change the metering tip if necessary to achieve the desired chemical/water ratio.
(10)Adjust the air pressure if necessary to achieve the desired foaming results. The system is set at the factory to 15
PSI pressure. Set the needle valve 1—2 turns counter-clockwise (from the fully closed clockwise position).
(11)To stop the system when finished, press the WATER (cycle stop) button.
IMPORTANT NOTES
•Changing the metering tips and/or air pressure should only be necessary during initial operation. There typically will
be no need to change these settings for normal day-to-day operation.
•If the air pressure is adjusted, or metering tips are changed, the eductors should be re-calibrated for greatest
accuracy when tracking chemical usage.
•The “time in” (that appears on the batch report) is logged when the user presses the START button.
•The “time out” (that appears on the batch report) is logged when the user presses the WATER button or when the
system operating time expires, whichever comes first.
•Product usage is tracked by the amount of time that the vacuum switch for each product is closed.
•If the RESET button is pressed during operation, the system will cease operation.
– The top line will show the display name.
– The bottom line will alternate between the date/time and the
display shown to the left.

PROGRAMMING
ILCS programming is done through the use of menu selections. Any menu can be entered by pressing the ENTER
button, or exited by pressing RESET (or in some cases MENU  or  ). Its that simple! Each of the main menu
headings give an idea of what information can be found, entered, or changed. Within each main menu selection are
several screen “prompts” that walk you through the complete programming process step-by-step.
Below is an example of the main display when the system is idle. The main display is more commonly referred to as
the
default display , and appears when the system is not in the programming mode.
ACCESS CODE ENTRY
The ILCS system has two access codes for protection:
•The "main" access code allows entry into ALL menus and functions, even when using WinReporter PC software.
•The "user" access code allows entry into the diagnostics menu only (at the control panel) without the ability of
changing programmed information. When using WinReporter, the user access code allows printing reports only.
Systems are shipped from the factory with both access codes set to zero. Only a person with the "main" access code
can change the "user" access code (changing codes is explained later in this manual). If desired the two access
codes can be the same, however the user will then have access to ALL of the functions of the system, including the
ability of changing programmed information.
IMPORTANT NOTES
•Leading zeroes on access codes and user passwords are not required to be entered. For example, a user
password of “010” can be more conveniently typed in as “10”, then press ENTER.
•It is recommended to clear the sum/batch report and batch count, then load factory defaults prior to initial
programming of the system. See MEMORY FUNCTIONS [menu 1] for details.
•If at any time you get lost in the programming and are not sure what to do, press the RESET button until the
section menu heading appears, then proceed.
From the default display shown above, press the ENTER button.
The screen at left should appear. If the screen at left does not
appear, wait 2 seconds, press RESET, then press ENTER.
When you see the screen at left, type in the access code and
press ENTER. Remember, for a new system, the access code will
be zero (until you change it later).
You are now in the programming mode. Follow the menus for
each section, starting on the next page.
ENTER ACCESS CODE
THEN PRESS ENTER
The default display shows your programmed display name on the
top line. The bottom line will alternate between date/time and the
message ENTER USER PASSWORD.
The “user password” should not be confused with the system’s
access code. User passwords allow multiple persons to operate
the system for dispensing chemicals, whereas the access code
allows entry into the menus for programming.
From the default display, you must enter the main access code
(following) to begin programming.

For accurate calibrations, adjust air pressure if necessary
and verify that the selected metering tip is giving the
proper dilution ratio before performing the steps below.
This can be done while priming the chemical lines. If
there are any future changes to air pressure or metering
tips, you should re-calibrate each eductor.
Use a container with calibration marks for this process,
such as a beaker or graduated cylinder. Also, make sure
that the chemical suction lines are fully primed.
1) Fill your container with product for the eductor you
wish to calibrate and note the amount.
2) Position the container under the end of the chemical
suction line for the eductor that will be calibrated and
turn on the manual valve for this eductor. Ensure
that the manual valves for the other eductors are off.
3) Point the foamer nozzle in a safe direction (away
from any persons) or into an acceptable drain and
turn the ball valve handle to open. Ensure that the
water and air supplies are both on.
4) Using the SCROLL and number keys, enter the
eductor number to be calibrated and press the CAL
button — the system will begin running and will draw
chemical from the container.

Point the foamer nozzle in a safe direction (away from
any persons) or into an acceptable drain, then open the
ball valve on the wand. Open each manual product valve
individually and look at the display to verify if name of
that product appears (example to the left).
•If the display does not show the chemical name
currently in use: There is either a problem with the
chemical being drawn or with the vacuum switch. First
check to make sure chemical is being pulled up the
line, then look for loose wires at the vacuum switch.
•If the display always shows a chemical name, even
when the product’s manual valve is closed: There is
either a short in the vacuum switch, or the pressure
relief line (that is teed into the switch) is blocked. Try
removing one or two of the inserts from the relief line.
When all eductor vacuum switches have been tested
press the PRIME/CAL button again to stop the system.
Be sure to close the ball valve on the wand, and all
manual valves. The water and air supplies may also be
