FIRST TIME START UP

1. Remove the black tank cover (cover not included on FX1234V) on the back of the unit by unscrewing the two thumb screws located on each

side of the cover. Remove the protective packaging from between the storage tank and the scale. See Figure A below.

Figure A: Shipping support to be removed before start up.

2. Plug the unit into the proper power source. Push the blue lighted power switch. All functions will be operated directly from the 7” Touch

Screen.

3. Connect service hoses to the machine.

4. Install oil purge bottle

Registration: To register your machine for warranty, please visit:

https://www.cpsproducts.com/support/equipment-warranty-registration/

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

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.

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.

MAINTENANCE AND CARE

Filter Changes

The lter/dryer has the capacity to dry 150lbs of recovered refrigerant. A lter life monitor is displayed on the Home

screen. When indicated the lter must be changed.

To change the lter:

1. Remove the black plastic tank cover. Have the lter reset code available before proceeding. It comes with each

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.
