After the installation of the processor unit is nished you can then proceed with the formulation tank unit.
1. Open the shipping box.
2. Remove packing and discard. Remove the loose items.
3. Remove the system from the shipping container. Unit is heavy and requires 2 people to lift it out of the box.
4. Place the formulation tank unit into the desired location.
5. Run 3/8” tubing from the RO Out on the processing unit to RO In (10 in “Formulation System Diagram” on page 4) on the
formulation unit.
6. Run the “Unit Connection Cord” from RO unit to the formulation unit (11 in “Formulation System Diagram” on page 4)
7. Plug in the power cord (“Installation Hardware” on page 5) to the formulation tank panel (12 in “Formulation System Diagram”
on page 4). Do not plug the unit into the wall outlet at this time.
8. Install the A Formula to the left side of the unit when facing the front. The location will be marked with a large A and have green
tubing fed to it. Install the tubing (3 in “Formula Installation & Replacement” on page 16) into the tting by fully inserting the
tubing about 1/2” into the tting.
9. Install the B Formula to the right side of the unit when facing the front. The location will be marked with a large B and have blue
tubing fed to it. Install the tubing (3 in “Formula Installation & Replacement” on page 16) into the tting by fully inserting the
tubing about 1/2” into the tting.
10. To connect the pressure tank to the formulation tank, reference the diagram below. The pressure tank does not need to be next
to the formulation tank, it can be placed anywhere before the rst point of use.
11. Locate the tubing on the water out to your points of use.
12. Cut the tubing where you would like the tank to be and insert the 1/2’ equal tee ( #2 ).
13. Place the tank in a safe location.
14. Teon the top stem on the pressure tank and thread on the angled stop valve ( #4 ). Place the enlarger ( #3 ) into the angeled stop

Follow each step to complete the start up:
1. First, verify all the plumbing connections are correct.
2. Verify that the “Delivery Pump” switch (5 in “Formulation System Diagram” on page 4) and the “Formulation” switch (6
in “Formulation System Diagram” on page 4) are in the o position.
3. Verify the lters are fully seated and locked into the housings.
4. Verify that the bypass on the RO unit (Location located in the processing unit diagram) and the formulation unit (1 in
“Formulation System Diagram” on page 4) are turned o.
5. Turn on the city water that is feeding the unit. Check for any leaks around or within the unit.
6. Plug the system into a outlet.
7. Check the incoming water pressure and make sure it is within 50 - 90 psi. If it is below you will need a booster pump to bring
the psi within the acceptable range. If it is above you will need a pressure regulator to bring the psi within the acceptable range.
8. Turn on the “Processing System” switch (7 in “Formulation System Diagram” on page 44). The water processing unit
should turn on and the outgoing pressure gauge should start to read pressure. It should read within 10 psi of the incoming
pressure gauge.
9. Let the tank on the unit completely ll. It will take about 30-45 minutes to ll the tank completely.
10. Double check the A & B Formula box connections.
11. Turn on the “Delivery Pump” switch (5 in “Formulation System Diagram” on page 4). Pump should pressurize and the
system gauge should read around 60 psi.
12. Do not turn on formulation switch until tank is full. When tank is full turn on the “Formulation” switch (6 in “Formulation System
Diagram” on page 4). The TDS controller should turn on and the 2 peristaltic pumps should begin to spin.
13. Verify TDS controller set points to verify they are within your parameters. (“Change The TDS Controller Set Points” on page
10)
14. Wait 5-10 minutes allowing the system TDS level to equalize. TDS levels are equalized when your TDS controller (4 in
“Formulation System Diagram” on page 4) is reading your desired TDS range.
15. Start Up is complete.

Taking Measurements
1. Remove the cap. (Do not use the cap for testing.)
2. Click the POWER button. The reading will always be zero in the air.
3. Make sure the TDS meter is set to test a 0.7 factor (442). It should say 0.7 in the top right of the screen. If not switch
the modes by following the directions in “Switching Modes”.
4. Dip the meter’s sensor into the water, liquid or solution to be tested.
5. Lightly swirl the meter to ensure the removal of air bubbles or electric charges.
6. The meter will display a reading instantly. Keep the meter in the water until the reading stabilizes (up to 5 seconds,
depending on the situation).
7. To view the reading out of the liquid, click the HOLD button. This will freeze the reading on the screen. Clicking HOLD
again will release it.
8. Click the POWER button to turn the meter o.
9. Shake any excess water o the meter and rinse with low TDS water (such as distilled, RO or DI), or use compressed
air to clean it. Put the cap back on.
Switching Modes
1. With the meter on, press and hold the MODE button.
2. The scales will cycle through on the display screen.
3. Release the MODE button when the desired scale is shown.
Temperature And Switching Temperature Modes
1. The temperature reading is always displayed on the LCD panel (except in calibration mode), and is shown simultane-
ously with EC/TDS readings.
2. The default mode for temperature is Celsius. To change the temp mode, quickly click the TEMP/CAL button to switch
from Celsius to Fahrenheit or vice-versa.
Care & Maintenance
1. If using the COM-80 for nutrients or high TDS solutions. ALWAYS RINSE THE SENSOR AFTER EACH USE. Rinse in
distilled or RO water, but tap water can also be used. Improper care will negatively aect readings and void the war-
ranty.
2. Your meter has been factory calibrated, which is sucient for most applications. The COM-80 will retain its calibration
for a long period of time, but recalibration may be necessary based on frequency of use, care and application of use.
3. Ideally, store the sensor dry (it should never be stored in water or a solution).
Changing the Batteries
1. When the meter displays a ashing battery symbol, your batteries are getting weak and should be replaced soon. To
change the batteries:
2. Pull out the blue battery compartment using your thumb nail.
3. Remove the three batteries.
4. Insert new batteries in the direction as depicted inside the compartment. The at side of the battery is the positive(+)
side. The meter uses LR44 batteries.
5. Close the battery compartment. Make sure it is tightly closed.
Calibration
Calibrating a scientic instrument is similar to tuning a musical instrument. Your COM-80 has been factory calibrated to
1413 µS (700 ppm), which is suitable for most applications, and is ready for immediate use. The meter will retain its cali-
bration for many years, depending upon care, frequency of use and application of use. If you need to recalibrate:
1. Obtain a certied EC/TDS calibration solution. Always calibrate close to the level you will be testing (or in the middle
of a range) .
2. Turn the meter on and insert into the solution. (Make sure the meter’s mode matches the composition of the solution).
If your meter shows the correct reading, stop here. If not, press and hold the CAL button for 5 seconds. The display
will ash and the temperature reading will change to a ashing ‘CAL’ image.
3. Adjust the reading to match the solution value with the UP or DOWN buttons (indicated by the arrows). When the
number matches the solution, click ENTER.
4. ‘CAL’ will ash briey, indicating progress. Allow a few seconds, do not press any buttons, and if possible, do not move
the meter.
5. When the meter is calibrated, ‘End’ will ash and the measurement will reappear.
6.
Temperature Calibration
If you need to calibrate the COM-80’s thermometer, only calibrate it in the air to a dierent, correct thermometer.
1. With the meter on and in the ll:, press and hold the POWER and TEMP buttons at the same time for 5 seconds.
2. ‘CAL’ and the temperature will ash on the screen.
3. Using the UP or DOWN buttons (arrows), adjust to the correct temperature.
4. Once you have corrected the temperature, click ENTER. ‘C -- CA -- CAL’ will ash on the screen and then ‘End’ will
briey appear. The thermometer is now calibrated.

Routine system check should be done on a daily and weekly basis to verify the system is functioning correctly. By checking the
system you can prevent a major problem from happening and increase the life span of the unit and its components..
Check on a daily basis
• Verify that all the gauges are reading the correct psi.
• Check to make sure that all of the switches are in there correct location.
• Make sure that the system bypass handles are in the o position. Please contact your service provider when bypass handle
is moved into bypass. Only emergency situations require putting the bypass handle into the bypass position.
• Listen for any changes in the sounds coming from the unit.
• Check to make sure that there is formula. Make sure to re-order when the level gets down to the re-order line. Failure to
change the formula before it runs out can damage the peristaltic pumps.
Check on a weekly basis
• Verify that there are no leaks on or around the system.
• Make sure the TDS reading from the TDS controller are within the desired range.
• Check the outgoing TDS levels and make sure it matches up to the reading on the TDS controller.

Step by step troubleshooting guide is designed for the store operator to avoid unnecessary service calls and expenses. Do
not hesitate to call for Technical Support if using this guide fails to x the problem. Please have the results of these step by step
checks ready before you call. Often the symptom or problem is not with the system itself, but with the power to the building or
city water pressure to the system. If no water is available to one POU (espresso or brewer) this is a sure sign the problem is not
with the system, but rather with the equipment the system supplies. Do not operate espresso machine or brew coee during
troubleshooting procedures, equipment damage may result. Y-STEP INSTRUCTIONS:
1. Check the system pressure gauge reading. If the pressure reading is normal, (35-60 psi), then there is no immediate problem
with the system. If the pressure moves below 35 psi or is at 0 psi, this means the city water pressure to system is too low
or the electric and/or water is turned o to system. See step 2.
2. Verify if power monitor is on. Check the system digital monitor to see if it is turned on. If not, push in the green button. If
the system now has electrical power, go to Step 3. If not, check to see if yellow switch is on; if not, or you had to plug in the
system, reset store electrical circuit breaker. Once power is returned, see step 3.
3. Check that water to the building is running by turning on a sink faucet. If water is running, check all water valves to the system
are turned on fully. If both steps show water is on and available to system, see step 4. If water to the system was not available
and is now restored to the system, wait 5 minutes for delivery pressure (above 35 psi) to be restored and for system pump
to begin running normally. See step 4.
4. If steps 1-3 fail to get the system producing water to the POU, call your Store Facility Service Center or GC Water immediately.
To supply water temporarily to the POU (points of use) (brewer, espresso, etc.,) bypass the system which will send city water
to the system instead of the system water. Turn the system into bypass by turning the yellow bypass handle on the front
faceplate from o to the bypass position.
NOTE: Tank will not rell while in bypass. System Pressure will read zero psi.
Do not place the system into “EMERGENCY BYPASS MODE” without informing the Store Management immediately.

GAUGE INFO
The pressure gauges will be able to show you what is going on with the system. This section will discuss the various uses and
meanings of the gauges. There is 3 gauges per system that are of importance to you.
Incoming Pressure gauge will show you the city water pressure that is feeding the water processing unit. This gauge can uctuate
depending on the city pressure. If it is below 50 then you will need a booster pump to increase the pressure to within the desired
level. If the line pressure is above 90 psi you will need a pressure reducer to bring the incoming psi to within the desired level.
Outgoing Pressure gauge will show you the water pressure that is coming out of the lters on the water processing unit. This
gauge should be relatively close to the incoming pressure gauge. It will typically sit about 5 psi less then the incoming pressure
gauge. If it is showing a dierence of 20 psi with the incoming pressure gauge your lters will need to be replaced right away.
The outgoing pressure gauge will have a resting psi of 0 psi when the storage tank is to maximum capacity. When the tank drops
below the pre set limit the outgoing pressure gauge will return to its normal operating pressure.
System Pressure gauge will show you the water pressure that is leaving your water storage tank out to your points of use. This
gauge should show a consistent psi. If it is cycling then you most likely have a leak at a point of use. If there is no psi reading
then you most likely have a pump issue.
