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

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

• Reconnect this hose to the
Recovery Tank Vapor
Port
.

.
• 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
