    Danger- The unit’s recovery tank contains liquid refrigerant. Overfilling of the recovery tank may cause a violent explosion resulting in severe injury or even death. Danger- Only use CPS Automotive recommended recovery tanks with this unit. See distributor for replacement tanks.

  • Page 3: Introduction

    The FX series is a fully automatic Recovery/Recycling, and Recharging Refrigerant work station. The FX134 Series meets and exceeds the new SAE J2788. FX1234 Series meets and exceeds the new J2843/J2788. The FX3030 Series meets and exceeds J3030. The FX134, FX1234, and FX3030 Series models are single circuit R/R/R machines for handling R134a, R1234yf from mobile AC systems.

  • Page 4: Summary Of Operation

    Many problems are a result of operator error. Please read the FX134/FX1234/FX3030 Series operating manual. The manual is separated into 4 Sections: Section 1 gives instructions on how to gain service access to the FX134/FX1234/FX3030. This Section also gives instructions on proper calibration and mechanical repair procedure Section 2 contains a list of common problems and how to resolve them.
  • Page 5 RECOVER/RECYCLE NOTE: The FX1234 and FX3030 will implement refrigerant indentifying process according to J2743. Refrigerant sample will pass through (SC2) low side service hose. The refrigerant sample will then pass through low side manifold valve (LV2) and (LS2) solenoid valve allow sample into identifier. Once refrigerant has been sampled and passes. The recovery unit will operate as instructed below.
  • Page 6 RECOVER- Oil Drain Flow Once Recover is done and the compressor shuts off. The air purge valve HS1 will open to pressurize DOA Chamber then HS1 will close. The compressor will come on to lower pressure in DOA for oil draining. Once pressure level is achieved, then (HV3) opens allowing excess oil to drain from DOA Chamber for 30 seconds.
  • Page 7 EVACUATION After the mobile a/c system is repaired, it should then be pulled into a deep vacuum to remove residual gasses and moisture before recharging it with refrigerant. The unit evacuates gasses from the a/c system through the LO Side and HI Side service hoses.
  • Page 8 CHARGE LOW SIDE NOTE: FX1234 and FX3030 will have addition steps in charging according to J2743. There will be a 10 minute vacuum test. The first 5 minutes the vacuum pump mode will run. (See Vacuum Plumbing Schematic) Then the second 5 minutes of the vacuum leak test is where it checks for vacuum loss.
  • Page 9 CHARGE HI SIDE NOTE: FX1234 and FX3030 will have addition steps in charging according to J2743. There will be a 10 minute vacuum test. The first 5 minutes the vacuum pump mode will run. (See Vacuum Plumbing Schematic) Then the second 5 minutes of the vacuum leak test is where it checks for vacuum loss.
  • Page 10 CHARGE BOTH LOW AND HI SIDE NOTE: FX1234 and FX3030 will have addition steps in charging according to J2743. There will be a 10 minute vacuum test. The first 5 minutes the vacuum pump mode will run. (See Vacuum Plumbing Schematic) Then the second 5 minutes of the vacuum leak test is where it checks for vacuum loss.
  • Page 11 REFILL NOTE: The FX1234 and FX3030 will implement refrigerant indentifying process according to J2743. Refrigerant sample will pass through (SC2) low side service hose. The refrigerant sample will then pass through low side manifold valve (LV2) and (LS2) solenoid valve allow sample into identifier. Once refrigerant has been sampled and passes. The recovery unit will operate as instructed below.
  • Page 12 AIR PURGE Air Purge is performed automatically on the FX134A / FX 1234 / FX3030 series. Two thermistors are used to determine if the storage tank have had enough time to stabilize. Once it is determine Air Purge can take place, the unit will open the charging solenoid valve (LS1) to the Pressure transducer (PT).
  • Page 13 REFRIGERANT IDENTIFIER The FX1234 and FX3030 will implement refrigerant indentifying process according to J2743. Refrigerant sample will pass through (SC2) low side service hose. The refrigerant sample will then pass through low side manifold valve (LV2) and (LS2) solenoid valve allow sample into identifier. Once refrigerant has been sampled and passes. The recovery unit will operate as instructed below.

  • Page 24: Section 2 Common Problems And Solutions

    Section 2. - Common Problems and Solutions The most common problems fall under one of the following categories: A. No Power to the unit after turning on Main Power Switch B. Circuit breaker trips when plugging the unit into power source C.
  • Page 25 Note: If the problem is not included in the above categories, please consult CPS service center support for addition information. A. No power to the unit after turning ON the Main Power Switch Possible Cause: Power Cord not connected correctly.
  • Page 26 Possible Cause: Vacuum pump oil is contaminated and/or cold causing the vacuum pump start windings to kick on and off upon start up. Solution: Replace vacuum pump oil. Use CPS Vacuum Pump oil. It is specially formulated for cold weather conditions. Possible Cause: Vacuum pump voltage switch is in the wrong position.
  • Page 27 G. Unit will not Charge, no pressure on Manifold gauges Possible Cause: Storage tank liquid valve and/or Liquid hose valve are closed Solution: Make sure the liquid supply to the charging solenoid valve has all valve open. Possible Cause: Charging Solenoid Valve is not energizing. Solution: Check to see if 12VDC is present on the Charging Solenoid Coil with the unit in the charging mode.
  • Page 28 J. Charging Inaccuracies- Over and Under Charging Possible Cause: Unit was moved during the Charging operation Solution: It is very important that when unit is charging, it is not bumped or in an area with excessive vibration during the CHARGING mode. The pneumatic wheels will help to reduce an external vibration.
