The following is recommended to maximize recovery rates:
A. Use shortest length of 3/8" (inside) diameter refrigeration hose on suction side of unit to vapor
port on tank.
B. Use 3/8" (inside) diameter refrigerant hoses from system liquid service valve to liquid port on
tank.
C. If refrigerant is clean, remove all suction side filters, screens, etc...
D. Remove all Schrader type valve cores and any valve depressors from the hoses and service
valves.
E. Use 90 lb DOT recovery tank or larger to minimize tank change over.
1. Connect unit as shown in Diagram 2

2. Open Liquid and Vapor Valve on Recovery Tank
3. Open OUT Valve on unit.
4. Set Auto-Manual Switch to MANUAL.
