ERROR MESSAGES
SYSTEM LEAKS: Error message displayed when the AC system
connections are not tight.
Solution: Verify the connections between the service hoses and
quick couplers, and make another 5 min vacuum test only on
service hoses . If the problem persists, delete the residual oil in
the service hoses making a short 4 oz (100 g) charge in the
service hoses and then a recovery, and repeat the 5 minutes
vacuum test on service hoses.
NOTE : If the vacuum test on service hoses passes, means that the
A/C system has a leak which must be localized using a leak
detector.
PRESENCE OF REFRIGERANT INTO THE A/C SYSTEM: Error
message displayed when starting the vacuum, the charging
station checks the presence of a pressure inside the A/C system.
Solution: Perform a recovery procedure.
LOW VACUUM: Error message displayed before charge if the
value of the vacuum> 400mbar.
Solution: Perform a quick vacuum procedure (at least 20
minutes).
EMPTY OIL CONTAINER: Error message displayed when the
charging station is unable to complete the set amount of oil
injection.
Solution: Fill the container with the correct amount of new oil for
compressors.
NOTE: Use only oils recommended by the manufacturer or
vehicle manufacturer. Never use oil used.
LOW GAS AVAILABILITY: Error message displayed during
charge, when you select a quantity greater than the availability of
gas.
Solution: Fill the inner refrigerant tank, refer to the Tank Filling
section of the user manual.
SYSTEM EMPTY: Error message appears when you select a
recovery procedure, but is not found pressure in the A/C system.
Solution: Check the connection and closing of the quick couplers.
If after all these checks, the machine continues to give the same
error, means that the A/C system is empty.
SET QUANTITY LOWER THEN 4 oz (100 g): Error message
displayed during charge when the amount of gas typed is less
than 4 oz (100 g) (both automatic and manual procedure).
Solution: Set a quantity of gas greater than or equal to 4 oz
(100 g).
CHECK CONNECTIONS: Error message displayed when the flow
rate of charge is too low.
Solution: Verify the correct opening of the quick couplers. Make
sure that the amount of gas in the refrigerant tank is > 3 lbs (1.36
kg), otherwise fill the inner refrigerant tank.
Rarely, it may happen that the temperature of the engine
compartment of the vehicle is too high compared to that of the
charging station. This can cause an immediate balance between
the refrigerant tank pressure and A/C pressure causing a
slowdown or interruption of the charge. To avoid this, it is
recommended not to fill A/C in a vehicle exposed to the sun or a
vehicle with the engine running.
EMPTY EXTERNAL TANK: Error message appears during the
process of charge the refrigeant tank when the pressure drops to
zero before the completion of the procedure.
Solution: Check the connections, quick couplers and valves on
the external tank; if the external tank is empty, replace it with a
full one. Then run another charge.
HIGH PRESSURE ALARM: Error message appears during the
recovery procedure, internal tank filling, empty hoses, or flushing
hoses, this occurs when the hydraulic pressure reaches
approximately 290 psi (20 bar). The causes may be:
Ambient temperature where is located in the station is too high.
Solution: To wait for a sufficient time to cool the charging station
before resuming the interrupted procedure.
Number of services performed by the station is excessive.
Solution: To wait for a sufficient time to cool the charging station
before resuming the interrupted procedure.
One of the taps of the internal tank is closed.
Solution: To open the tap and resume the interrupted procedure.
