Connect the unit as shown in Diagram 1.The technician will need to use a refriger- <br /> ant manifold and one spare hose. The manifold should be connected between the unit <br /> beina serviced and the TR21 IN non The snare hose should connect from the TR21 <br /> OUT port to an evacuated DOT recovery tank vapor valve. Note:The recovery tank <br /> must be rated for(38 bar)550 PSI. <br /> 2. Open the vapor valve on the OOT recovery tank. <br /> 3. Keep the manifold valves closed at this time. <br /> 4. Push the main power switch"ON". <br /> 5. Once unit has started,open both HI&LO manifold valves to start the refrigerant <br /> recovery flow. <br /> Note:The TR21 is designed to directly recover large amounts of liquid refrigerant. If <br /> during vapor recovery process the compressor begins to make a slugging or hammering <br /> noise, meter the incoming liquid refrigerant by closing the low side manifold valve until <br /> the noise subsides. <br /> 6. The TR21 will run continuously.When a 10"hg.vacuum is observed on the low side <br /> manifold gauge,close both the LO & HI side manifold valves off. <br /> 7. If the pressure on the HI side manifold gauge starts to rise,repeat steps 4-7. If HI side <br /> manifold gauge remains in a vacuum,close all tank, manifold and hose valves. Re <br /> move discharge hose from TR21 outlet port.Recovery and Self-Clearing are now <br /> complete. <br /> Figure 18.1—Recovery Instructions, the Solvent Vessel MUST BE RATED TO 550 PSI for this pump <br /> 9/1/2015 Project: 150703 Terpp MK IV CLE Report Page 18 of 44 <br /> KD Doc. 150703ER <br />
