Refrigerant Recovery System
Model 3600
10
Step
Description
6
Monitor the LED status display
. The unit will shut off automatically when the proper vacuum
level is achieved and the status display LED will turn off.
LED
Description
Green
Indicates that the power switch is ON and the compressor is running.
If the green LED is off, this indicates that the unit has shut down because
the system being evacuated has reached 13" HG. (the evacuation is
complete). Check the suction pressure to verify that the system being
evacuated is down to at least 13" HG vacuum. Turn the system switch
to the OFF position. Wait 5 minutes. If the inlet pressure rises above 0
psig. Repeat steps 3-6. If the inlet pressure remains below 0 psig, close
all valves and disconnect the hose from the A/C system.
NOTE:
A small amount of inlet pressure may be needed to reset the
vacuum switch, this is normal.
Red
(a)
Indicates that there is a high-pressure condition that must be
corrected. Check for restrictions or a full recovery tank. Correct
the problem and turn the system switch OFF to reset the system.
Repeat steps 3-6.
(b) Indicates that the recovery tank is full (if the 80% automatic shutoff
option is installed). Change the recovery tank and repeat steps
3-6.
7
Purge the system by positioning the inlet and purge ball valve in the “PURGE” position
(both pointing DOWN).
This should be done with the unit off. If the valves are turned while
the unit is running, the system may shut off either on high-pressure or vacuum. If the unit is
manually or automatically turned off before the evacuation is complete, repeat steps 3-7.
NOTE:
If the circuit breaker trips, wait 5 seconds, reset circuit breaker and go to step 3. If
the compressor thermal overload trips, wait 16 to 30 minutes before restarting.
