5. INFORMATION BEFORE OPERATING THE RG5410 hp RECOVERY UNIT READ THE FOLLOWING 1 Always isolate large amounts of refrigerant and close off valves after use so if a leak should develop anywhere in the system the refrigerant does not escape 2 Storage cylinders sometimes have valves that are not properly seated when manufactured Keeping caps on these valves will guard against refrigerant leakage 3 Always operate the unit on a flat level surface 4 Your RG5410 hp has one internal pressure shut off switche If the pressure inside the system should go above 38 5 bar 550 psi the system will automatically shut itself off CAUTION The 38 5 bar 550 psi switch does not prevent tank overfill If your system shuts off on high pressure and is connected to your tank you may have overfilled your tank and created a very dangerous situation Take immediate measures to relieve any high pressure and or tank overfill 5 WARNING Never overfill storage tanks may cause tanks to explode 6 Tanks and filters should be designated for one refrigerant only Before using a tank previously used for another refrigerant completely empty the tank evacuate it purge the tank using dry nitrogen and re evacuate it Use only Promax Amprobe storage tank part No RGT30 hp or RGT50 hp with this refrigerant recovery equipment 7 Special care should be taken when recovering from a burned out system Use two high acid capacity filters i
6. Safety Pressure Switch If the pressure inside the system exceeds 27 5 bar the system is switched off automatically If the Safety Pressure Switch is activated automatically whilst filling a bottle it could be caused by the bottle becoming overfilled THIS IS A VERY DANGEROUS SITUATION You should take steps immediately to reduce the overpressure and or to eliminate the overfilling of the bottle If the Safety Pressure Switch switches the unit off The following precautions should be taken if the Safety Pressure Switch is activated a Suspected overfilling of the recovery bottle Connect the recovery bottle to another bottle with spare capacity so that the pressure is reduced to a safe level This action should also reduce the pressure in the output line from the RG5000 Proceed as normal after resetting the Safety Pressure Switch see below b Cause of activation of Safety Pressure Switch unknown Check that the recovery bottle is not overfilled Close the system valves recovery bottle valves and RG5000 valves Disconnect RG5000 from flexible pipes Disconnect RG5000 from the power supply Open the input and output valves very slowly Investigate the reason for the failure Once activated the Safety Pressure Switch has to be reset manually as follows Remove the black protection cover to reveal the reset button see picture below Reset by pushing the reset button with a tool such as a screwdriver Replace the cover 15
7. use an empty tank that has been fully evacuated to achieve the final vacuum level required To maximize recovery rates use the shortest possible length of 3 8 or larger hose A hose no longer than 3 0 is recommend Always remove all unnecessary hose core depressors and Schrader valves from port connections using the proper valve core tool for maximum throughput Deformed rubber seals and core depressors in hoses and faulty or unnecessary Schrader valves can restrict flow by up to 90 If the tank pressure exceeds 300 psi use the tank cooling procedure to reduce the tank pressure When recovering large amounts of liquid use the PUSH PULL method of recovery see diagram below CAUTION When using the PUSH PULL method you must use a scale to prevent overfilling the storage tank Once the PUSH PULL siphon is started it can continue and overfill the storage tank even if the tank is equipped with a float level sensor The siphon can continue even when the machine is turned off You must manually close the valves on the tank and the unit to prevent overfilling the recovery tank 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 A scale must be used to avoid overfilling the storage tank OPTIONAL MOISTURE INDICATIING SIGHT GLASS The sight glass is used to provide

13. if a leak is suspected Refrigerant vapor is hazardous to your health and can cause death Always think before acting Familiarity breeds carelessness and carelessness can be harmful to your health or worse result in death Read the Material Safety Data Sheets MSDS on all compounds with which you are likely to come in contact Read MSDS on refrigerant and refrigerant oil Obtain MSDS sheets from your refrigerant supplier Never use oxygen when testing for leaks Any oil in contact with oxygen under pressure will form an explosive mixture Refrigerant systems are generally electrically driven and controlled Be sure to disconnect the unit from the power source before servicing it Always store refrigerant containers in a cool dry place Always open service and cylinder valves slowly This allows quick control of the flow of gasses if there is any danger Once it is determined that there is no danger the valves may be opened fully Do not mix refrigerant in a system a tank or anywhere else Each type of refrigerant must have its own tank filters etc If moisture enters the refrigerant system it is likely to cause considerable damage Keep everything connected with the refrigeration system thoroughly dry and clean This equipment should be used in locations with mechanical ventilation providing at least four air changes per hour or the equipment should be located at least 45cm 18 above the floor
14. irements of ARI 700 latest edition As a result recycling and verifying ARI 700 conformance isn t economically justified in most cases It s still a great idea to do as much cleaning of refrigerant going back into the same system or owners system as possible We recommend using the largest high acid capacity filter that are economically feaslble Put these filters on the suction or inlet side of the recovery unit Change filters often The recovery of large amounts of liquid refrigerant can sometimes carry with it large quantities of oil if the system being serviced doesn t have an adequate oil separator installed If this recovered refrigerant isn t going to be liquid charged back into the same system you might want to separate the refrigerant from the oil in order to measure the oil to know how much oil to charge back into the system However refrigerant sent back for reclaim does not need to have the oil removed One of the simplest and most cost effective ways to achieve this is to use a 30 or 50 Ib tank in line with your recovery machine Connect the the system to the liquid port of the tank then from the vapor port of the tank connect to the input of your recovery machine a second tank for storing refrigerant should then be connected to the output of the recovery machine If you encounter large amounts of liquid you will need to put a band heater around the first tank When the recovery job is complete the oil can be removed from the fir

16. st one tank for every refrigerant type serviced plus an extra for burnouts and other unknowns Planning Ahead Knowing the quantity of refrigerant is important for planning storage requirements as well as planning for the actual recovery For instance any system with more than 5lbs of refrigerant is likely to have areas where the liquid can get trapped The key to a quick recovery procedure is to get the liquid out first and then get the remaining vapor out However most systems are not recovery friendly That is they don t have access ports at their lowest points If some units you re servicing are on maintenance contracts you would save significant time by installing access ports at all of the lowest points in the system where liquid is likely to accumulate Since most systems don t have these ports you need to be prepared to boil of the trapped liquid with a heat gun when ever it s found An indicator of trapped liquid in a system is frost or condensation forming on the plumbing or components where the liquid is trapped The trapped liquid may be in an area that is not visible In all cases trapped liquid in a system during recovery causes the recovery process to slow down regardless of the size or type of machine If you are unable to locate the trapped liquid but you know it s there because the recovery job is taking forever turn on the system compressor if it s operable for a few seconds This will get the refrigerant moving
