Refrigerant Recovery System Model 3600 Part No. 2000-3600 Operation & Maintenance Manual Instruction 2079-0140 Rev 2 - December 2012 WARNING: Inhalation of high concentrations of refrigerant vapors is harmful and may cause heart irregularities, unconsciousness, or death. Deliberate inhalation of refrigerants is extremely dangerous and death can occur without warning. Vapors reduce oxygen available for breathing and are heavier than air. Decomposition products are hazardous.

Model 3600 Refrigerant Recovery System CHAPTER 2: SAFETY 2.1. General Safety Instructions 1. KNOW YOUR EQUIPMENT Read and understand the operation manual and labels affixed to the unit. Learn its application and limitations as well as the specific potential hazards of your equipment. 2. GROUND ALL EQUIPMENT This unit is equipped with an approved three pronged grounded power cord and plug. The green wire is the ground wire and should never be connected to a live terminal. 3.
Refrigerant Recovery System Model 3600 2.2. Operational Safety WARNING: Inhalation of high concentrations of refrigerant vapors is harmful and may cause heart irregularities, unconsciousness, or death. Deliberate inhalation of refrigerants is extremely dangerous and death may occur without warning. Vapor reduces oxygen available for breathing and is heavier than air. Decomposition products are hazardous. Liquid contact can cause frostbite.
Model 3600 Refrigerant Recovery System CHAPTER 3: FEATURES 3.1. Location and Description of Unit Features # Component Description 1 Purge Ball Valve 2 Inlet Port Ball Valve 3 LED Status Display This valve determines what function the Model 3600 performs. This valve is UP during recovery operations and DOWN for purging and liquid push-pull operations. Opens or closes the inlet port. It is pointing UP (open) for all recovery operations and points DOWN for purging operations.
Refrigerant Recovery System Model 3600 3.2. LED Display LED Green Meaning Normal Operation Red High Pressure Condition Red Tank Full Explanation Indicates that the power switch is ON and the compressor is running. Indicates that there is a high pressure condition that must be corrected. The internal high pressure switch activates at 550 psi. Indicates that the recovery cylinder is full (if the Automatic 80% Tank Full Shutoff Option is installed).
Model 3600 Refrigerant Recovery System CHAPTER 4: RECOVERY 4.1. Helpful Hints for Recovering R-410A R-410A has been designated by the EPA as a “very-high-pressure” refrigerant. Because of its higher vapor pressure, recovering R-410A has some unique challenges. The higher vapor pressure requires more work from the compressor, resulting in higher temperatures and increased wear on moving compressor parts.
Refrigerant Recovery System Model 3600 Step Description 6 Monitor the LED status display. The unit will shut off automatically when the proper vacuum level is achieved and the status display LED will turn off. LED Description Indicates that the power switch is ON and the compressor is running. Green If the green LED is off, this indicates that the unit has shut down because the system being evacuated has reached 13" HG. (the evacuation is complete).
Model 3600 Refrigerant Recovery System 4.3. Liquid/Vapor Recovery Hose Connections Figure 1. Liquid/Vapor Recovery Hose Connections Use only approved DOT recovery cylinders. Follow precautions and warnings listed on the cylinder. If servicing a system with a compressor burn-out, use a high acid type filter drier and do not reuse. Recovery Mode Storage Mode Figure 2.
Refrigerant Recovery System Model 3600 4.4. Liquid Push-Pull Recovery General Information Attention: Before attempting the following liquid push-pull recovery operations, please review this page. It may not be possible to recover liquid refrigerant from some types of refrigeration equipment. A scale or liquid sight glass can be used to determine when all the liquid is recovered. The unit will not pull a vacuum using the push-pull liquid recovery operation.
Model 3600 Refrigerant Recovery System 4.5. Liquid Push Pull Recovery Procedures Liquid push-pull operations are performed by using hot compressor gas to push liquid refrigerant out of a system. The purge valve accomplishes this by re-directing the hot compressor gas around the condenser. See the diagram on top of the unit for hose connections. Step Description 1 Turn off all electrical or mechanical power to the refrigerant device to be evacuated. 2 Make proper hose connections.
Refrigerant Recovery System Model 3600 4.6. Liquid Push-Pull Hose Connections Figure 3. Liquid Push Pull Hose Connections Use only approved DOT recovery cylinders. Follow precautions and warnings listed on the cylinder. If servicing a system with a compressor burn-out, use a high acid type filter drier and do not reuse. Liquid Push-Pull Mode Storage Mode Figure 4.
Model 3600 Refrigerant Recovery System 4.7. Pump Down Operations The Model 3600 is equipped with a pump-down purge valve that allows the technician to pump down or evacuate the 3600 before proceeding to the next recovery operation. This procedure not only eliminates cross contamination, but also conserves refrigerant. Follow the steps below to ensure your pump down operation is performed correctly.
Refrigerant Recovery System Model 3600 4.8. DOT Recovery Cylinder Safety An optional 80% recovery cylinder shutoff cord is available with the Model 3600. If equipped, this cord connects to the recovery cylinder float switch and will automatically shut the Model 3600 off when the recovery cylinder becomes 80% full. When the Model 3600 is equipped with the 80% shutoff cord, Bacharach recommends that you use this cord for added safety.
Model 3600 Refrigerant Recovery System CHAPTER 5: TROUBLESHOOTING Problem Compressor Will Not Start LED Status Unit Starts But Stops After a Few Minutes of Operation Solution • Green LED Vacuum pressure switch has been activated Turn unit off. Apply 1-2 psig pressure to inlet port to reset vacuum switch • Red LED Check for restrictions in the discharge line. Ensure that the tank valves and discharge valves are open. Remove restrictions in the high side.
