The following is recommended to maximize recovery rates:
A.
Use the shortest length of 3/8"(inside) diameter refrigeration hose on the suction
side of the 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 the 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.
Connect the unit as shown in Diagram 1.
1.
EU Note: The recovery tank must be rated for 38 bar.
2.
Open the Vapor Valve on the Recovery Tank.
Open OUT Valve on unit (Do NOT Open IN Valve at this time).
3.
4.
Set Auto-Manual switch to MANUAL.
Push the Main Power Switch "ON".
5.
When unit starts, open IN Valve on unit to start refrigerant flow.
6.
For automatic shut off, set Auto-Manual Switch to AUTO
7.
Monitor amount of refrigerant in Recovery Tank.
8.
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 the noise subsides.
In AUTO position, unit will shut off when suction pressure falls to 10" hg vac, and RED LP
9.
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.
RECOVERY PROCEDURE IS NOW COMPLETE. CLOSE ALL VALVES AND DISCONNECT HOSES
