ERROR CODES
Error #1: The air or gas readings were unstable.

Solution: Move the unit away from sources of EMF or RFI such as radio transmitters
and arc welders.
Error #2: The air or gas readings were excessively high.

Solution: Move the unit away from sources of EMF or RFI such as radio transmitters
and arc welders.
Error #3: The air calibration resulted in a low output.

Solution: Prevent refrigerant from flowing into the unit through the sample inlet during
air calibration.

Solution: Allow any refrigerant in the atmosphere to dissipate before performing air
calibration
Error #4: The unit is beyond the operating temperature range

Solution: Move the unit to an area where the ambient temperature is within the
specified operating range.
Error #5: The refrigerant sampled has an excessively large amount of air or there was little or
no sample flow due to plugged sample line gas analyzer filter. This is the code to prompt the
user to change the filters. This should be considered more as a prompt than an actual error.

Solution: Verify the coupler valve is open.

Solution: Verify the gas analyzer filters are not plugged with debris or oil

Solution: Replace gas analyzer filters
Error #6: SYSTEM LEAKS: Error message displayed when the A/C system is 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 100g filling in the servicehoses and
then a recovery, and repeat the 5 minutes vacuum test on service hoses.
N.B. if the vacuum test on service hoses passes, means that the A / C system has a
loss which must be localized using a leak detector.
