m IMPORTANT SAFETY INFORMATION m SAFETY COMES FIRST! Read all safety, operating guidelines and instructions before operating your RG5410A. 1. CAUTION: ONLY A QUALIFIED TECHNICIAN SHOULD OPERATE THIS RECOVERY UNIT. The operator must be familiar with air conditioning and refrigeration systems, refrigerants and the dangers of pressurized components. 7. Read all safety information regarding the safe handling of refrigerant and refrigerant oil, including the Material Safety Data Sheet.
OPERATING GUIDELINES m Before operating the RG5410A recovery unit, read the following m NEVER use a standard disposable 301b. ta, .1% (the type of container in which virgin refrigerant is sold) to recover refrigerant. 1. RG5410A IS APPROVED FOR USE WITH THE FOLLOWING CATEGORY III, IV and V REFRIGERANTS (Per ARI 740): 9. storage tank. DO NOT OVERFILL. Tank is full at 80% volume. Tank may explode if filled more than 80% due to liquid expansion.
OPERATING GUIDELINES - cont. 15. To maximize recovery rates, use the shortest possible length of 3/8" or larger hose. A hose no longer than 3 feet is recommended. 16.For maximum throughput, always remove all unnecessary hose core depressors and the Schrader valves from port connections. 17.Deformed rubber seals and core depressors in hoses and faulty or unnecessary Schrader valves can restrict flow up to 90%. NOTE: If there is no liquid in the recovery tank, then the cooling method will not work.
ADDITIONAL RECOVERY TANK INFORMATION m Warning: tank, evacuate it and purge the tank using dry nitrogen, and then re-evacuate it. Also read the information pertaining to recovery tanks, previously listed under Safety Information and Operating Guidelines. 3. Always store refrigerant containers in a cool dry place. 1. CAUTION: NEVER use a standard disposable 30 lb. (the type of container in which virgin refrigerant is sold) to recover refrigerant. Use ONLY authorized refillable refrigerant tanks.
PURGING NON-CONDENSABLE GASES FROM REFRIGERANT TANK 5. If the pressure reading is higher than the pressure shown on the chart, very slowly (so as not to cause turbulence inside the tank) crack open the vapor port valve. Watch the pressure on the gauge decrease. To prevent venting, add 4-5 psi to the pressure shown on the chart. when the gauge corresponds to that pressure, close the vapor port valve. 1. Allow the tank to sit undisturbed for 24 hours. This allows the air to rise to the top. 2.
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. The following are some tips and pointers we've accumulated over the last few years that can save you time and make the process go smoother.
HELPFUL HINTS FOR REFRIGERANT RECOVERY - cont. This is probably never noticed in charging, because the pressure opens the grommet, but during recovery (or with suction) the deformed grommet severely restricts the flow of refrigerant. REFRIGERANT RECYCLING Current regulations state that used refrigerant shall not be sold, or used in a different owner's equipment, unless the refrigerant has been laboratory analyzed and found to meet the requirements of ARI 700 (latest edition).
OPERATING YOUR RG5410A PROCEDURE FOR NORMAL SYSTEM RECOVERY 8. Slowly open the input port on the RG5410A. a. If the compressor starts to knock, slowly throttle back the input valve until the knocking stops. b. If the input valve was throttled back, it should be fully opened once the liquid has been removed from the system (the manifold gauge set vapor port should also be opened at this time). 1. Inspect the RG5410A thoroughly to insure that it is in good operating condition. 2.
SELF PURGING YOUR RG5410A PROCEDURE FOR PURGING REMAINING REFRIGERANT FROM THE RG5410A 1. Close the ports of the system being serviced that are connected to the input port of the RG5410A. 7. Close the ports on the recovery tank and the RG5410A. 2. Close the input port on the RG5410A. 8. Turn the RG5410A off. 3. Turn off the RG5410A. 9. Return the Recover/Purge valve to the Recover position. 4. Turn the Recover/Purge valve to the Purge position. 10.Disconnect and store all hoses. 5.
DIAGRAM FOR “PUSH/PULL” METHOD Push/pull method only works with large systems where the liquid is readily accessible. Do not use this method on systems that contain less than 15 lbs. as it may not work. The sight glass is used to provide a method of determining the moisture content and quality of a system’s refrigerant. m CAUTION: When using the “Push/Pull” method, once the siphon is started, it can continue and overfill the storage tank even if the tank is equipped with a float level sensor.
OPTIONAL RECOVERY/TANK PRE OR SUB COOLING FOR FIXED HOSE SET-UP MANIFOLD GAUGE SET INPUT SYSTEM BEING SERVICED OUTPUT LIQUID VAPOR LIQUID m A scale must be used to avoid over filling the storage tank. 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.
