DIRECT VAPOR OR LIQUID RECOVERY
The following is recommended to maximize recovery rates;
A. Use shortest length 3/8" (Inside Diameter) Refrigeration Hose on Suction Side of Recovery Unit.
B. If refrigerant is clean, remove all suction side filters, screens, etc.
C. Remove all Schrader type valve cores and any valve depressors from hoses and service valves.
D. If Recovery Unit trips OFF on HIGH Pressure, change recovery cylinder.
E. When recovering large amounts of R410A, or if recovering under very high ambient temperatures, we
suggest using the CPS MT69 (Molecular Transformator) which will increase the recovery speed.
1. Connect the unit as shown in Diagram 1. The technician will need to use a refriger-
ant manifold and one spare hose. The manifold should be connected between the unit
being serviced and the TR21 IN port. The spare hose should connect from the TR21
OUT port to an evacuated DOT recovery tank vapor valve. Note: The recovery tank
must be rated for (38 bar) 550 PSI.
2. Open the vapor valve on the DOT recovery tank.
3. Keep the manifold valves closed at this time.
4. Push the main power switch "ON".
5. Once unit has started, open both HI & LO manifold valves to start the refrigerant
recovery flow.
Note: The TR21 is designed to directly recover large amounts of liquid refrigerant. If
during vapor recovery process the compressor begins to make a slugging or hammering
noise, meter the incoming liquid refrigerant by closing the low side manifold valve until
the noise subsides.
6. The TR21 will run continuously. When a 10" hg. vacuum is observed on the low side
manifold gauge, close both the LO & HI side manifold valves off.
7. If the pressure on the HI side manifold gauge starts to rise, repeat steps 4-7. If HI side
manifold gauge remains in a vacuum, close all tank, manifold and hose valves. Re
move discharge hose from TR21 outlet port. Recovery and Self-Clearing are now
complete.
