clogged filter will slow recovery rate.

1. Use a 5/8" socket or boxed end wrench to remove IN port as
shown in Figure 1.
2. Remove suction port-filter cartridge as shown in Figure 2.
3. Clean cartridge or replace with new cartridge. (CPS #CRXF3)
4. Inspect 0-ring. Re-lubricate with compressor oil or equivalent
5. Place filter cartridge back into suction port fming.
6. Hand tighten this assembly back onto TRS21.
7. Use 5/8" socket or boxed end wrench to tighten 1/8 of a turn. Do
not over tighten; 0-ring damage may occur.
8. Check connection for leaks.
Piston Seal Maintenance: In cases of virgin refrigerant
recovery, it is recommended to add .25 ounce of refrigerant
oil to inlet port before each use.
