If at the end of Recovery process a sufficient vacuum has been maintained, the Ariazone will
stop, and the display (2) will indicate alternately 'DONE' and the amount of refrigerant recovered
will be displayed in (kg or lb) depending on the operator’s selection.
Press 'STOP' on the console, the unit will display "busy" for 5 seconds.
The values for the quantity of refrigerant recovered will be automatically printed.
Recovered Oil Drain
After completion of recovery function, the unit will automatically drain the recovered oil (if any) into
recovered oil vessel (9) to electronically calculate amount of oil that has been recovered. The
value of the recovered oil will be automatically printed.
Conditions that will halt the recovery mode
The above sequence assumes that neither the stop button was pressed, or that no undesirable
condition occurred. The following conditions will cause the Ariazone unit to halt the recovery
function.
1. Refrigerant cylinder (12) full. To protect the storage cylinder from being overfilled, the unit will
not allow the operator to recover refrigerant once it has reached 80% of its capacity.
2. Air conditioning system empty. If the A/C system pressure is not above atmospheric
pressure, the recovery function will not be activated.
3. High Pressure. If the operating pressure of the Ariazone exceeds 26 bar (350 psi), the
Ariazone unit will stop and display 'H- PRES'. The following can cause the above:
• Cylinder (12) valves not open.
• Restricted cylinder hose (16). Check the ball valves.
• Excessive high ambient temperatures.
• Excessive air in refrigerant cylinder
• Faulty pressure control
• Recovery pump thermo control faulty.
In all the above circumstances, press the 'STOP' key to return to the machines initial mode.
