In order to solve problems please keep exactly to the security norms mentioned in Chap 1.
PROBLEM Solving
The station does not switch-on;
The main switch does not
illuminate.
Control the security of the mounted line on the switch-on block.
At switch-on the display remains
switched-off; the main switch does
not glow
1) Control the cabling on the switch board display.
2) possible default: power supply – switchboard CPU
Call the technician.
The display shows a completely
false amount of gas within the
bottle.
1) Control the tightening of the screws of the balance sensor;
2) Calibrate the balance (chap. 6.6 technical service);
Call the technician.
The recovery starts but no gas is
being recovered.
Possible default:
1) Compressor;
Call the technician.
The station is blocked in the
recovery phase;
The high and low pressure gauges
are on zero;
1) Calibrate if possible the pressure control.
The station finishes the recovery
phase but the high- and low
pressure gauge show the presence
of gas (> zero).
1) Calibrate if possible the pressure control.
The station is blocked in the
recovery phase;
The high- and low pressure gauges
are under pressure.
Close the cock within the bottle:
1) The station finishes the recovery phase (gauge on zero):
Electro-charging valve EV2 blocked.
2) The station remains furthermore within the recovery phase:
Possible default: Compressor Art OMT021CR000.
Call the technician.
The charging phase starts but the
gas does not come out of the
Station;
The high and low pressure gauges
remain on zero.
Possible default:
One-Way-Valve of charging (after the electro valve) Art.
0RR026CR000.
Call the technician.
Smoke comes out of the pump in
the vacuum phase; the sound of the
pump is not normal/regular.
Possible suction of air;
1) Close the cock of the station and try anew, whether the pump is
starting its function, control the joints of the tubes and connectors.
2) Control the oil level of the pump.
The display shows ever ERR2
during the leak test.
1) close the cocks and try to perform a vacuum for 5 minutes, if no
leaks are signalized, control the joints of the tubes and the quick
couplings.
2) Should the problem persist call the technician.
When no fresh oil is being charged
into the A/C station.
1) Control the integrity of the fresh oil tank.
2) Call the technician.
