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:

http://motorvac.com/FXRegister

5. Press the key to enter your shop information into your unit. This information will appear on certain screens and on print outs.

Pressing 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 FX134a.

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 FX134A 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 ﬁlling 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 (GUI) that makes operations intuitive. In this sec-

tion, we will cover each operation’s objective. The screen provides the speciﬁc information and directions during operation, so the descrip-

tions below are limited to operation theory.

Recovery

Select “Recovery” if you want to recover and recycle refrigerant currently in the vehicle prior to opening the system for repair.

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 refrigerant. The refrigerant passes through a coalescing ﬁlter 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 through-

out the process and at the end. The ending amount may be printed by pressing the icon visible on the Home screen after recovery is

completed.

Vacuum

Select “Vacuum” if the vehicle system is void of refrigerant and is ready to be recharged. Vacuuming the vehicle utilizes the FX Series’ 6 CFM

vacuum pump to pull air and boil moisture from the AC system. A speciﬁc vacuum time may be selected by entering the time (in minutes)

on the displayed key pad. If a vacuum time of 10 minutes or greater is selected, vacuuming will be followed by a 2 minute leak test (vacuum

decay test).

If pressure equal to or greater than 5 psi is observed, the vacuum pump will not start and you will be advised to perform the recovery func-

tion prior to attempting vacuuming. Results may be printed by pressing the icon on the Home Screen.

Charge

Select “Charge” to reﬁll the vehicle system to its designed capacity. Enter the desired charge amount using the displayed keypad. Units other

than that selected at start-up may be selected using the “units” key. If the required charge amount is not visible on the vehicle or if the J639

tag is missing from the vehicle, the FX series offers a database feature that allows the user to look up the correct charge for most vehicles

sold in North America since 1994. Press the key to access this feature.

The FX134a will charge in the liquid phase through the ﬁlter/dryer into the hoses until the desired charge amount is reached. The unit will

then ask if you want to enter the Car Health mode. Do so if you want to check/print system pressures and vent temperature. If you choose

no to Car Health, the machine will guide you through the process to move the refrigerant contained in the hoses into the vehicle’s AC system.

The FX134A is equipped with a heat blanket but if it cannot complete the 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 sequence. Results may be printed by pressing the

icon on the Home Screen.

THEORY OF OPERATION

OTHER FUNCTIONS

Change Units

This function will be displayed when setting the charge amount. It allows

you to change from the default unit of measure to that on the J639 tag on

the vehicle. For instance, if 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 (if desired) and charge the vehicle AC system. The display will prompt you to

enter a vacuum time and a vehicle charge amount. As described in the “Charge” sequence, the database may be used to retrieve the charge

amount for most vehicles sold in North America.

Once Full Cycle has been selected and started, the machine will proceed with the recovery process described above. At the end of recovery,

the unit will automatically proceed to vacuuming and leak test (if the vacuum time selected was greater than 10 minutes.) Once vacuuming

is complete, the desired charge amount will be installed in the vehicle. The unit will then ask if you want to enter the Car Health mode. Do so

if you want to check/print system pressures and vent temperature. If you choose no to Car Health, the machine will guide you through the

process to move the refrigerant contained in the hoses into the vehicle’s AC system.

The user may print the results by pressing on the “Home” screen.

Tank Reﬁll

Select “Tank Reﬁll” 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 prior to beginning any operation. If the tank contains less than this amount, 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 ﬁlter life.

Start by connecting the red hose to the liquid port on the supply cylinder using the supplied adapter. For virgin cylinders with one port, turn

the tank upside down once connected and open the tank valve and coupler.

Follow the directions on the display until the process is completed.

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.

Loading new Firmware

From time to time ﬁrmware updates will become available. Should you need to install updated ﬁrmware; ﬁles will be sent to you to place onto

a USB stick. Go to the mode and select After selecting, the machine will guide you through the process, including telling you when

to insert the USB stick into the USB port. When complete, the machine will reset. When the Home screen appears, it is complete.

MAINTENANCE AND CARE

Filter Changes

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

screen. When indicated the ﬁlter must be changed.

To change the ﬁlter:

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

new ﬁlter.

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 certiﬁed 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 certiﬁed 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 FX134a 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 ﬁlter are all open. If all valves are open, then contact technical support to determine the

cause of the alarm.

Tank Overﬁll 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 overﬁll 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.
