Operating Instructions — System Flush
13. Refer to Figure 11 and select SYSTEM FLUSH
from the main menu . Press OK .
14. Accept the default vacuum time or program a
greater amount of time. Press OK .
15. The recovery machine pulls a vacuum for the
programmed amount of time and then performs a
5-minute leak test. Failure of the leak test indicates
a leak in the system or connections, or possibly a
pressure rise due to system out-gassing. In that
case, check and tighten all connections and restart
the vacuum process.
16. After a successful vacuum and leak test, the
machine automatically runs a pressure test and
recovery of the flushing circuit using a small
amount of refrigerant.
After a successful pressure test and recovery,
the machine performs four flushing cycles in
the opposite direction of normal system flow.
Each flushing cycle uses a maximum of 3 kg of
refrigerant and is followed by a recovery.
At the end of this procedure, the system will be
recovered and evacuated.
CAUTION: The flushing kit has a replaceable filter
as well as a debris strainer, both of which can
get plugged. At the end of the flush cycle, check
the high-side (red) gauge for system pressure,
and check the adapter for complete removal of
refrigerant.
If pressure exists or refrigerant remains, exit the
flushing cycle and enter the recovery mode to
recover refrigerant through both the high- and
low-side (blue) hoses. Then service the filters and
repeat the flush process.
17. Upon completion of a successful flush and
system reassembly, replace any oil lost during the
process. Refer to the vehicle service manual for
additional instructions.
