Conditions that will prevent automatic cycle procedure
a. If there is little or no refrigerant in cylinder (12). Display shows "ADD REF".
The operator must add refrigerant into unit cylinder (12) (see item 7)
b. If the recovered oil vessel is full, the "recovered oil led" will flash and display will show "OIL
FULL". The operator must empty the oil vessel.
Note: If the recovered oil vessel becomes full during the oil drain, the led will flash and process will be
stopped. Display will show "OIL FULL". Operator must empty the vessel and press "STOP". The automatic
cycle will then continue.
New value of the recovered oil will be added to the previous and at the end the printed report will show total
amount of the recovered oil.
c. If new oil vessel is empty, the "new oil led" will flash and display will show "ADD OIL".
The operator must fill the oil vessel.
Note: During the process of oil injection, if there is insufficient oil in the new vessel, the display will show
"ADD OIL". The operator must add the oil in the vessel and press "STOP". The automatic cycle will
continue.
d. Refrigerant cylinder (12) full. To protect the storage cylinder from being overfilled, the Ariazone
unit will not allow the operator to recover refrigerant once it has reached 80% of its capacity.
e. If the hand manifold valve (4) console are closed.
f. If the A/C system service port Schrader valve is not depressed
g.
High Pressure. If the operating pressure of the Ariazone exceeds 26 bar (350 psi), the
Ariazone 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
