  • Page 3 Advanced Test Products Europe RG3000-E THE SAFE WAY IS THE ONLY WAY! NOTE! If you are not a qualified refrigerant service technician, do not use this equipment 1. The technician should always wear goggles and gloves when working on refrigeration systems.
  • Page 4 Advanced Test Products Europe RG3000-E REFRIGERANT GAS RECOVERY & CONTAINMENT Safety comes first. Read all safety information for the safe handling of refrigerant including the Material Safety Data Sheet provided by your refrigerant supplier. Never operate unit in an explosive environment. Wear safety glasses and protective gloves.
  • Page 5 Keeping caps on these valves will guard against refrigerant leakage. 2. Always operate the unit on a flat level surface. 3. Your RG3000-E has one internal pressure shut off switch. If the pressure inside the system should go above 38,5 bar (550 psi), the system will automatically shut itself off.
  • Page 6 RG3000-E OPERATING YOUR RG3000-E Connect your RG3000-E to a 230 V outlet and close both valves on the RG3000-E. Open the valves to the cylinder and system and make sure no air is in the hoses, only clean refrigerant. Open the outlet valve on the unit .Switch the main power switch to the ON position.
  • Page 7 RG3000-E could result in the acidic degradation of internal components, ultimately causing premature failure of the unit. CAUTION When pumping liquid, do not allow the RG3000-E to operate with the inlet valve too far open, causing the compressor to knock. Doing so may damage the compressor.

    3. Run the unit until desired vacuum is achieved. 4. Turn the RG3000-E off. 5. Close the valves on the recovery tank and the outlet valve on the RG3000-E. 6. Disconnect and store all hoses. 7. Replace the in-line filter on your RG3000-E after each time excessive contaminant is encountered.
  • Page 9 Advanced Test Products Europe RG3000-E RG3000-E REFRIGERANT RECOVERY ADDITIONAL INFORMATION To achieve the deepest final vacuum, use the tank cooling method to lower the head pressure on the recovery tank. Repeat as necessary to achieve the desired vacuum level. NOTE: If there is no liquid in the recovery tank, then the cooling method will not work. In this case, use an empty tank that has been fully evacuated to achieve the final vacuum level required.
  • Page 10 Advanced Test Products Europe RG3000-E SET-UP DIAGRAM FOR REFRIGERANT RECOVERY This method is the fastest method for recovering vapor refrigerant. SET-UP DIAGRAM FOR “PUSH/PULL” METHOD Push pull only works with large systems where the liquid is readily accessible. Do not use this method on systems that contain less than 15 pounds as it may not work.
  • Page 11 Advanced Test Products Europe RG3000-E OPTIONAL RECOVERY / TANK PRE OR SUB COOLING FOR FIXED HOSE SET UP Normal recovery: Tank Vapor valve is closed. Tank pre or sub cooling: Tank Vapor valve is open and both Manifold Gauge Set valves are closed. Follow above procedure.
  • Page 12 Advanced Test Products Europe RG3000-E RG3000-E RECOVERY Purging the non-condensable gasses from identified refrigerant in a tank 1) Allow the tank to sit undisturbed for 24 hours. (This allows the air to rise to the top). 2) Connect a manifold to the tank and read the amount of pressure in the tank by looking at the outlet pressure gauge.

  • Page 16 SAFETY PRESSURE SWITCH (WITH AUTO RESET FUNCTION) The RG3000-E is equipped with an internal Automatic Safety Pressure Switch. If the pressure inside the system exceeds 38,5 bar, the system is switched off automatically. If the Safety Pressure Switch is activated automatically while filling a bottle, it could be caused by the bottle becoming overfilled.
  • Page 17 If the unit is to be stored or not used for any length of time, we recommend that it be completely evacuated of any residual refrigerant and purged with dry nitrogen. Whenever you perform any type of maintenance work on your RG3000-E, ensure that it is disconnected from the power supply before you begin.

  • Page 19 Advanced Test Products Europe RG3000-E HELPFUL HINTS FOR REFRIGERANT RECOVERY Refrigerant recovery has come a long way in a few short years. On the surface it’s simply the process of taking refrigerant out of a system and putting it into a tank. However, this simple process can quickly become problematic if a few items are overlooked.
  • Page 20 Advanced Test Products Europe RG3000-E HOSES AND VALVES Hoses and Schraeder valves have a large impact on recovery speed. In general, the larger the hose, the less friction on the flow of refrigerant, the quicker the recovery time. Many contractors are now using 3/8” lines for the inlet to the recovery machine, even if those lines originate out of 1/4”...
  • Page 21 Advanced Test Products Europe RG3000-E KEEPING THE DIRT OUT During the recovery process your recovery machine can be exposed to debris that can, potentially, damage it. Including brazing spatter and copper and brass slithers. Further contamination can be introduced from the refrigerant storage tanks. To prolong the life of your recovery machine always use an in-line filter.
