DIRECT VAPOR OR LIQUID RECOVERY
The following is recommended to maximize
recovery rates:
A. Use shortest length of 3/8" (inside) diameter refrigeration
hose on suction side of TR700 series.
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. Use an evacuated DOT recovery tank.
E. If unit trips off on high pressure, change recovery
cylinder.
F. When recovering large amounts of R410A, or if
recovering under very high ambient temperature,
we suggest using the CPS brand MT69 Molecular
Transformator.
1. Connect unit as shown in Diagram 1.
EU Note: Recovery tank must be rated for 38 bar.
2. Open Vapor Valve on Recovery Tank.
3. Open OUT Valve on unit (Do NOT Open IN Valve
at this time).
4. Set Auto-Manual switch to MANUAL.
5. Push Main Power Switch "ON".
6. When unit starts, open IN Valve on unit to start
refrigerant flow.
7. For automatic shut off, set Auto-Manual Switch to
AUTO
8. Monitor amount of refrigerant in Recovery Tank.
WARNING: Do not over fill Recovery Tank.

Note: The unit is designed to handle large
amounts of liquid refrigerant. If during direct
liquid recovery the compressor begins to make
a slugging or hammering noise, meter in the
incoming liquid by closing the IN valve until noise
subsides.
9. In AUTO position, unit will shut off when suction
pressure falls to 10" hg vac, and RED LP Light
will energize. In MANUAL position, unit will run
continuously.
• Monitor IN Gauge
• Set Main Switch to OFF once required vacuum
level is reached.
10. The following instructions are to reduce the amount
of residual refrigerants:
• Open IN and OUT Valves. Select AUTO on Auto-
Manual Switch.
• Disconnect service hose(s) from equipment being
serviced.
• Reconnect this hose to the Recovery Tank Vapor
Port.
• Set Main Switch to ON.
• Slowly open Recovery Tank Vapor Port so IN
Gauge reads 60-70 PSIG. Run for 30 seconds.
• Close IN Valve. Unit will automatically shut off
when vacuum is reached. The RED LP Light will
energize.
