INTRODUCTION
Thank you for purchasing the Flo-Dynamics Convertible FLO1000 series unit. The FLO1234 has been designed to meet both R-134a and R-1234yf SAE R/R/R Standards. In accomplishing this goal, Flo-Dynamics has integrated the latest patent pending technology and incorporated state of the art features while improving relaibility and performance. The unit also meets the SAE standards for High Voltage
Compressor service that many hybrid vehicles require.
The FLO1234 can also handle contaminated refrigerants with is special pumpdown and complete evacuation process. It gives the end user a truly one machine meets all needs.
The FLO1234 series primary use is an Automotive R/R/R unit. The FLO1234 automatically recovers, recycles, evacuates, and recharges mobile A/C systems. Simply hook up the service hoses, choose the desired operation, and allow the unit to automatically complete the A/C service.
The FLO1234 utilizes a single pass (oil coalescing, particle filtration, and moisture removal) recycling system, which means that whenever the FLO1234 recovers, it also recycles. The unit also incorporates automatic air purge to remove unwanted non-condensable gasses from the refrigerant. Thus the refrigerant storage tank always contains the cleanest refrigerant possible for future recharge use.
The FLO1234 utilizes patented motorized ball valves. The motorized ball valves are unique to the industry in that they will not be affected by sealants, particulates, and other contaminates. The motorized ball valves incorporate passage ways 8-15 times larger than the existing solenoid valves orifice technology. In fact the FLO1234 uses no solenoid or check valves in the active flow path during recovery or evacuation, thus enhancing speed.
The FA1234 utilizes a patent pending two cylinder oil-less compressor. This compressor improves reliability and performance. Being oil free, no compressor oil maintenance or oil return system is required.
The following are additional features:
• Integrated manifold gauge set. Visually see how the mobile A/C system is operating. No manual valves to open or close.
• Large Graphic LCD to view operating instructions. Languages include English, Spanish, French, German, Chinese and more
• A highly accurate electronic charge scale
• Microprocessor Integrated mass flow system keeps track of how much refrigerant has run through the filter drier giving the user maximum amount of run time on each filter (150 LBS per filter)
• Cartridge type 41 inch cubic filter drier. Mounted directly on the storage cylinder for optimal moisture removal and weight accuracy
• Automatic high-pressure shut-off with microprocessor indication
• Interchangeable Recovery cylinders. Use your country’s approved refrigerant cylinders. The software allows the user to set up the proper tank and refrigerant parameters. Larger cylinders can be used for larger truck and bus A/C systems.
• Modular design for easy replacement of a defective plumbing, scale, electronic, compressor or vacuum pump sub system
• Heavy-duty construction: Powder coated steel cabinet mounted onto a 1” tubular steel frame
• 10" pneumatic rear wheels and 4” swivel casters give this unit excellent maneuverability under the worst of conditions
• Recovers and Evacuates through both the high and low side service hoses
• Separate Vacuum pump for faster evacuations
• Additional service hose lengths available, 8 foot comes standard
• Programmed electrical outlet for optional heater blanket installation
• Charges on both High and Low side
• The FLO1234 can easily be converted back and forth between four different refrigerants: R-134a, R-1234yf, R-22 and R-407C
To help you get a good start, please continue to carefully read the balance of this manual. This manual contains important information on the proper procedures for operating this equipment. Please pay close attention to the safety information, Warnings, and Cautions provided throughout this manual. Always remember “Safety First”.

MAINTENANCE
MAINTENANCE MODES: DURING NORMAL OPERATION OF FLO1234
FILTER CHANGE: The FLO1234 uses a mass flow tracking system on how much recovered refrigerant has passed through the Filter Drier (FLO p/n ARXF5). Each 41 Cubic Inch Drier can handle 150 lbs. of refrigerant before requiring change. When it is determined that the filter has exceeded the 150 lbs., the unit locks out (if in SAE mode) the recovery function in both RECOVERY and FULL CYCLE. It is necessary to purchase a Filter Drier under FLO p/n ARXF5. Each new Filter Drier comes with a unique code to unlock the recover/recycle function. The FLO1234 has a lower tilt drawer design to hold 2 spare filters.
When choosing the RECOVER or FULL CYCLE modes, the FA1234 will remind the user to order a filter when the
FILTER LIFE REMAINING is below 25%.
The following is an example of the LCD when Filter Life is less than 25%: Push the CONTINE key to proceed to filter change.
When the Filter Life reaches 0%, the following LCD screen will come up. Push the CHANGE FILTER key to begin filter change procedure.
Note: pushing QUIT key at this time will return the unit to the Main Menu. While in the SAE mode, all functions except

MAINTENANCE
CHANGE REFRIGERANT (continued):
Remove the tank hose service cover using a 9/16” wrench, disconnect the tank hoses from the bulk head fittings on the back of the unit. Disconnect the ground wire clamp from the tank. Remove the entire tank/filter /hose assembly from the back of the unit. It will be necessary to use FLO kit FA1234X1 (50 lb tank/filter/hose assembly) for additional refrigerants. Place either a new pre-evacuated 50 lb tank/filter/hose assembly or an existing one on the scale platform. Connect the tank Red hose to upper bulk head fitting. Connect Blue tank hose to lower bulk head fitting.
Reconnect ground wire clamp to tank.
Remove the service hose cover. Install the correct service hoses for the refrigerant selected.
• The unit comes with the R-1234yf service hoses.
• For R-22 or R-407 refrigerant selection, purchase FLO hoses (HP8RE
and HP8BE).
Once done, re-install the service hose cover.
Push the CONTINUE key. The unit will proceed to do the automatic PT
(Pressure Transducer) calibration and then (if required) the air purge. This should only take a few minutes and once complete the Main Menu will appear on the LCD.
If there are any questions on confirming the refrigerant selected, turn OFF the unit. Then turn the unit ON. The LCD will briefly show the current refrigerant selected.
The LCD will have a list of refrigerants. Push the Key next to the refrigerant selection.

Maintenance - Interconnecting Hoses, Service Hoses and Couplers:
The FLO1234 uses brass to brass seal type fitting on the ends of the service hoses and interconnecting hoses. No hose gasket maintenance is required on brass to brass type connections. The fittings connecting to the filter drier do use a rubber hose gasket. When changing the filter drier, check the gaskets for wear. Replace if required. Periodically inspect all refrigerant hose assemblies, service hoses and both service coupler inner o-rings for wear. Replace the component(s) if excessive wear or leakage is observed. Periodically leak-check all hose connection points, hose ball valves, and service couplers. Since the unit does pull a vacuum in the recovery process, excessive Non-Condensable
Gases (NCG’s) could be sucked into the system and placed in the storage tank.

NOTE: When injecting oil back into a high voltage A/C system, use the OEM recommended oil. Purchase FLO injecting kit (AR2788X23) for additional injectors for different OEM oils.
TROUBLE SHOOTING
Problem: High Pressure Limit.
Solution: Check that both Storage Tank valves are open. Check that any inline hose ball valves to the Storage Tank are open.
Problem: Tank Overfill.
Solution: Remove refrigerant from Storage Tank by charging into an empty refrigerant cylinder. If this does not fix the problem, then Re-Zero scale.
Problem: Unit not Charging accurately.
Solution: Make sure Storage Tank is properly placed on platform so that no portion of the tank is touching the back of the unit or protective frame work of the unit.
Solution: Do not move the unit while in the charging mode. The unit utilizes a weighing method of charging.
Sudden movement of the storage tank will affect the charging accuracy.
Solution: Make sure unit is on a level surface. If placed on surface with more than 2% grade, the charging amount may be incorrect.
Problem: Unit will not power up.
Solution: Check to make sure circuit breaker on back of unit is not tripped. Reset and restart the unit if necessary.
Solution: Make sure power cord is plugged into the back of the unit and the wall receptacle.
Problem: Upon compressor start up, the circuit breaker trips.
Solution: Reset circuit breaker and try again.
Problem: Upon vacuum pump start up, the circuit breaker trips.
Solution: Check Oil Level in vacuum pump. Reset circuit breaker and try again.
Solution: Make sure vacuum pump voltage switch is in the correct position.
