5. Press the key to enter your shop information into your unit. This information will appear on certain screens and on print outs. Press-
ing will cause the unit to proceed with set up without personalizing your unit. Selecting will cause the unit to ask you later if you
want personalize your FX1234.
6. When personalization has been completed, press OK and the unit will proceed through self-calibration. When complete, the Home screen
will appear.
7. Select the Gear icon to enter mode to change the default language, Date/Time and units of measure. The FX1234 will allow you to
modify the weight unit of measure prior to entering the charge amount. This feature anticipates that the vehicle may be asking for a unit of
measure that is not your selected default.
8. Fill the internal storage tank. From the Home screen, select Connect the red high side hose to a virgin, or recycled refrigerant tank
using the supplied tank adapter. Refrigerant will be moved from the external tank to the internal tank in a liquid state. Therefore, a virgin
tank may be turned upside down, or if lling from a recycled tank, the hose may be connected to the “liquid” port. Follow the directions on
the FX display.
Congratulations, your FX Series Refrigerant Management Center is ready to use.
Note: Each time the machine is turned on it MUST be disconnected from a vehicle

THEORY OF OPERATION
7
FX Series Refrigerant Management Centers feature a touch screen graphical user interface that makes operation a breeze. In this section, we
will cover each operation and what the machine is actually doing. While the screen provides much of this information during operation, the
descriptions below will offer more detail than can be displayed.
Recovery
Select “Recovery” if you want to recover and recycle refrigerant currently in the vehicle prior to opening the system for repair. This process
will begin by checking the refrigerant in the vehicle system. If the refrigerant is at least 98% pure R1234yf, recovery will commence automati-
cally. If the refrigerant is less than 98% pure, the recovery function will not be allowed and the machine will vent the hoses to prevent internal
contamination of the machine and storage tank. Note: DO not connect service hoses to refrigerant source until instructed to do so.
The recovery process creates a vacuum on the vehicle system, pulling the refrigerant into a distillation chamber. The chamber has a coil inside
that is heated by compressor outlet gas. This process distills the refrigerant (turns it to gas) and separates liquids and debris from the refriger-
ant. The refrigerant passes through the chamber and compressor and is condensed into a liquid before coming to rest in the internal storage
tank.
The process ends when the machine detects that the system is void of refrigerant. The machine will display the amount recovered throughout
the process and at the end. The ending amount may be printed by pressing the icon visible on the Home screen after recovery is com-
pleted.
Vacuum
Select “Vacuum” if the vehicle system is void of refrigerant and is ready to be recharged. Evacuating the vehicle utilizes the FX Series’ 6 CFM
vacuum pump to pull air and boil moisture from the AC system. A specic vacuum time may be selected, or one of the preset times may be
used. If a vacuum time of 15 minutes or greater is selected, vacuuming will be followed by a 2 minute leak test (vacuum decay test).
Charge
Select “Charge” to rell the vehicle system to its designed capacity. Enter the desired charge amount. An A/C Database feature is built into the
FX1234, but will not have data available until 2016.
The charging sequence begins with a 10-minute vacuum leak test. This is an SAE requirement in SAE J2843 (R1234yf systems only). If the
system passes the vacuum leak test, the machine will charge the system to 15% of the selected charge. At this time, an electronic leak detector
meeting SAE J2913 for R1234yf is used to leak test the evaporator(s). After performing the leak test, the user will select the appropriate answers
to the displayed questions and proceed with charging. The FX1234 will continue allowing the remaining 85% of the charge. The FX1234 is
equipped with a heat blanket to assist in completing charging, but if the FX1234 cannot complete a charge due to pressure equalization, it will
notify the user to close the high side coupler and start the vehicle. This process will quickly complete the charge.

THEORY OF OPERATION
OTHER FUNCTIONS
Change Units
This function will be displayed when setting the charge amount. It allows
you to change from the defaulted unit of measure to that on the J639 tag
on the vehicle. For instance, the machine default was set to lbs:oz and the
vehicle tag provides refrigerant capacity in grams. Use this feature to
change the unit of measure to grams for this charge only.
Add Oil
This icon appears the end of the charge operation and is a reminder to add back the amount of oil that was removed during recovery. If you
had entered the amount of oil after charging, that amount will also appear with the icon. If not, check the oil discharge bottle to determine the
change in volume since the last recovery. Add this amount back to the system.
8
Full Cycle
Select “Full Cycle” to recover, recycle, vacuum, leak check and charge the vehicle AC system. The display will prompt you to enter the vehicle
charge amount. As in the “Charge” sequence, the database may be used to retrieve the charge amount for most vehicles sold in North America.
The full cycle process begins with a refrigerant purity test and the vehicle system. This is required for SAE2843 for R1234yf only. Note that if
you have purchased the FX1234W, you will need to have an external identier connected to the machines USB port at start up. If the system
passes the purity test, the machine will proceed with recovery.
The Full Cycle process continues after recovery with pre-charge vacuuming and leak testing. Leak testing is required under SAEJ2843 for
R1234yf systems. The system is rst vacuumed. After vacuuming, the 5-minute vacuum test is performed. If vacuum is held, the unit will pro-
ceed to adding 15% of the selected charge amount to the system. Using a SAE J2913 approved leak detector, inspect the evaporator(s) for leaks
and answer the displayed questions. If the system passes leak detection, the machine will continue charging the remaining 85%. If the leak
tests fail, the machine will recover any refrigerant and return to the Home screen. After the leak is repaired, the process can be run again. The
results may be printed by pressing the icon visible on the Home screen after Full Cycle is complete.
Tank Rell
Select “Tank Rell” to add refrigerant to the internal storage tank. It is suggested that at least 4.5 lbs or 2 kg of refrigerant be available in the
storage tank to begin any operation. If less is observed, choose this operation to add refrigerant to the internal tank. This operation transfers
refrigerant in the liquid state to the internal storage tank. The Refrigerant amount transferred in this mode is not counted toward the lter life.
Start with hoses disconnected and couplers closed. Press “Tank Rell” and follow the on screen instructions.
Caution: If hoses were connected be fore instructed, the machine will post a warning and instruct that the couplers be closed and the hoses
removed. Not doing so will result in refrigerant loss at the user’s expense.

OTHER FUNCTIONS

Car System Health Mode
This mode allows for checking of system pressures and vent temperature before and after servicing the AC
system. System parameters can be printed while in this mode to provide a before and after comparison.
When entering the Car Health mode, the machine will prompt you to start the AC system. You can then
collect and print readings. If you plan to recover next, press the button. You will be taken to the
Home screen. If all is well, press and the machine will guide you through clearing the hoses of
refrigerant back into the AC system.
Change Unit of Measure or Language
Press the maintenance icon and select . This will take you to a screen to allow you to select
either or .
Air Purge
The FX series features automatic air purge at unit start up. An air purge may also be selected in the maintenance mode. Air purges reduce “non-
condensable gases” in the storage tank to an acceptable level and may take a few minutes to complete. Do not turn the machine off or unplug
the unit during an Air Purge cycle.

new lter.
2. On the display Press the key and select . Then select
3. Follow the displayed directions. Replace the black tank cover when completed.
Scale Maintenance
Use this mode to check, tare or calibrate the internal tank scale. To access “Scale Maintenance”, press the icon, then select
Select the desired function and follow the on screen instructions. To perform the “Test” mode, you will need to remove the black plastic tank
cover and then use the 1lb test weight included with the system. The Test mode will alert the user to the need to re-calibrate the scale.
A requires lifting the tank while operating the display. It is best to have two people available for and
Use to reset the empty tank weight to zero, thereby enabling indication of the refrigerant weight. Calibration is suggested only if the
calibration test was off by more than .02lbs. Calibration may be performed by a service center. CPS technical support can also assist with the
process. Calibration requires a certied 25lb weight.
Pressure Transducer Maintenance
Use this mode if you suspect that the internal pressure transducer readings are inaccurate. The internal pressure transducers are used during
recovery, vacuum, air purge and in the manifold mode.
To enter this mode, press the maintenance icon. Then select PT. This will allow the transducer to be set, or calibrated. Calibration will
require a certied pressure source of 180 psig. Setting zero requires removal of the system hoses.
Follow the displayed direction for the select transducer maintenance function.
High Pressure Alert
The FX1234 will alert the user should a high pressure condition exist on the outlet side of the compressor. When such a condition is detected,
the compressor will be turned off and not allowed to restart until the high pressure condition is remedied. In such case, check that the tank
valves and hose ball valves to the tank and lter are all open. If all valves are open, then contact technical support to determine the cause of the
alarm.
Tank Overll Limit
The FX Series’ 50lb internal storage tank is designed to contain a maximum of 38lbs of refrigerant. If this amount is exceeded, the user will
be alerted and system operations will be halted. Before normal operation can continue, the overll condition must be remedied by moving
refrigerant from the FX tank to another storage tank or into a vehicle AC system. The charge function may be used to transfer internally stored
refrigerant to an external storage facility.
