8. Filling cylinder with refrigerant
Unit cylinder (12) may be filled with refrigerant by following procedures.
a. Using disposable cylinder
Connect the suction (blue) service hose (5) to a storage cylinder liquid valve by using the adapter
hose (17). Open liquid valve on the storage cylinder, open service hose quick coupling (5) and
hand manifold blue valve (4) .
With "UP & DOWN" keys, select the recovery function. By pressing "START" key, select amount
of refrigerant to be transferred, with the UP and DOWN key. The Ariazone unit will automatically
transfer the selected amount of refrigerant from the storage cylinder to the Ariazone cylinder (12).
When the selected amount of refrigerant is transferred, close the storage cylinder valve and allow
the Ariazone to recover the refrigerant in the service hose (5). Once the function is completed the
Ariazone will display the symbol "done" and the amount of refrigerant transferred will be displayed
in kg or lb on main display (2).
b. Using refillable cylinder
Have cylinder sitting upright, connect the suction (blue) service hose (5) to storage cylinder liquid
valve by using the refrigerant transfer hose (17) supplied, open liquid valve on storage cylinder,
open service hose quick coupling (5) and console blue hand valve (4)
Important:
a. Always keep a minimum of 2 - 3 kg in the 5001 cylinder (12).
b. Do not allow the cylinder to be filled above 80% capacity.
c. Never transport an overfilled cylinder. Refrigerant expands when heated and
may cause the pressure relief valve to open and exhaust refrigerant in to the
atmosphere or the cylinder may rupture.

9. Connecting Ariazone 5001FA to the A/C system
Use the service hose (5) quick-connect couplers to connect the hoses to the A/C system service
ports, bearing in mind that BLUE must be connected to the low-pressure (suction) side and RED
to high pressure (discharge) side.
If the system is equipped with a single service port, connect only the relative hose.
Note: Before connecting the quick couplers, clean the a/c ports of any foreign material.
Winding the quick coupler hand wheel clockwise, will allow the refrigerant to flow through the
hoses. Turning hand wheel in opposite direction, the flow will be closed. If there is any refrigerant
in the air-conditioning system, the pressure gauges will indicate a pressure rise.
Important: Console manifold hand valves (4) need to stay closed, not to allow
refrigerant to enter the service equipment until the required function has been
selected.
Ariazone 5001 gauges (suction & discharge) are important and useful instruments, the operator
should have basic understanding between gauge reading and air-conditioning system operation,
in order to correctly diagnose any possible system malfunction.

15
10. Individual function selection procedure
With this procedure, all functions (refrigerant recovery & recycling, A/C system evacuation,
recovered oil drain, new oil and UV dye injection and refrigerant charge) can be performed
individually.
The values for the quantity of refrigerant recovered, quantity of the oil recovered, vacuum time,
quantity of oil injected and quantity of refrigerant charged into the a/c system are automatically
printed at the end of each single operation.
10.1. Recovery & Recycling Mode
The purpose of the Recovery & Recycling mode is to recover refrigerant from the air conditioning
system, which will condense, purify and store the liquid refrigerant in the storage cylinder ready
for re-use.
To initiate the Recovery mode, press the 'DOWN' key once, followed by 'START' on the console.
Display will show "- - - -". Now, there are two choices:
1. To recover all the refrigerant from a storage cylinder or A/C system, press “START” again.
2. To select quantity of refrigerant to be recovered or transferred from a storage cylinder or A/C
system, use the "UP" or "DOWN" keys to select the desired amount, and press "START”
Note: Open the hand manifold valves (4) on the console to allow the flow of the
refrigerant from the a/c system before making the above selection.
Also, open valves on the unit storage cylinder (12) and ball valve on the cylinder
liquid hose (16).
During the recovery process, the 'Recovery' mode enunciators will now be ON and the display (2)
will indicate the amount of refrigerant being recovered.
In normal operation the above condition will be maintained until a vacuum of -0.4 bar (15 In Hg) is
reached at either the discharge or suction ports. When this occurs, the machine will beep once,
and the Ariazone will enter the recovery "PAUSE" mode. In this mode, the Ariazone will shut
down the recovery function and pause for 3 min., which during this time the recovery mode
enunciator will be ON constantly. The display (2) will indicate "PAUSE". During this function, the
Ariazone is monitoring whether the air-conditioning system pressure is increasing, due to any
refrigerant that may be left in the accumulator or dryer. If the pressure increases above zero, the
machine will re-start the recovery function automatically recover the remaining refrigerant.

16
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.

17
10.2. Evacuation Mode
In the evacuation mode the air and moisture in the air conditioning system is removed and
exhausted to the atmosphere. The evacuation pump in the Ariazone system is capable of
developing a vacuum of -0.99 bar (29.99 in hg). The evacuation mode runs for a predetermined
time selected by the operator.
To initiate evacuation mode, press the 'DOWN' key twice, followed by the 'START' key. Select the
desired evacuation duration by pressing the 'UP' key to increase or ‘DOWN’ key to decrease time
duration. Once the desired time has been selected press the 'START' key and the function will
commence.
Note: During evacuation mode manifold hand valves (4) on the console must be
open.
The evacuation time can be set from one minute to eight hours.
At any time the evacuation time can be paused or cancelled by pressing the stop button once to
pause, or twice to cancel the function.
The Ariazone 5001 system has a unique function that if the evacuation function is selected and
there is residual refrigerant in the air conditioning system, greater then 0.6 bar or 9 psi, the unit
would detect this condition, whereby it will beep six times to warn the operator. After this warning
the unit will automatically recover the residual refrigerant once it has recovered the entire
refrigerant it will start the selected evacuation function automatically.
Leak testing: After the evacuation process is completed, close both hand valves on
console (4). By closing the valves the unit is "isolated" from the A/C system to allow for
monitoring of any possible vacuum leak, which may exist in the air- conditioning system.
This is achieved by monitoring the suction and discharge gauges or micron gauge
connected on the vacuum port (18).
After completion of evacuation function, the unit will automatically print the report.

18
10.3. Oil or UV dye Injection Mode
The purpose of this function is to batch a user-defined quantity of refrigerant oil or UV dye from
the oil reservoir (10) on the Ariazone 5001 to the vehicle air-conditioning system.
Important: The Ariazone 5001 requires that the air conditioning system has
previously been evacuated to a maximum vacuum before this function can be
carried out.
Open the discharge (Red) and suction (Blue) hand manifold valves (4) on the console. Make sure
you have sufficient oil in the oil reservoir (10).
Select the Oil Injection mode by pressing the ' UP or DOWN' keys, followed by the 'START' key.
Select the desired amount of refrigerant oil 'UP' key to increase or ‘DOWN’ key to decrease the
value. Once the desired amount has been selected press the 'START' key and the function will
commence.
After completion of oil injection, the unit will automatically print the report of the oil injected into
the A/C system.
Conditions that will prevent oil injection
The Ariazone will not inject oil if the following conditions exist:
-Insufficient vacuum.

19
-Hand manifold valves (4) not opened on console.
-Schrader valve on A/C system service port not depressed.
-No oil in the reservoir (10).
10.4. Refrigerant Charge Mode
The purpose of the refrigerant charge mode is to batch a user-defined weight amount of
refrigerant into the air-conditioning system.
Important: Ariazone recommends that the A/C system is always properly
evacuated for a minimum time of 30 min and vacuum leak tested, before refrigerant
is charged in to the A/C system. This process will help protect our environment
and the air-conditioning system.
To initiate charging mode, press the 'UP' key twice, followed by the 'START' key. Select the
desired refrigerant amount by pressing the 'UP' key to increase or ‘DOWN’ key to decrease. The
smallest increment of refrigerant charge weight is 0.02 kg. If the units of weight are to lb the
smallest increment of refrigerant charge weight is 0.02lb. The maximum refrigerant weight that
can be set at this point is determined by the actual refrigerant weight available in the cylinder (12).
Holding the 'UP' or 'DOWN' keys for longer than two second will cause the increments of weight
change to increase or decrease rapidly.
Once the refrigerant charge weight has been set, press the 'START' key and open appropriate
hand manifold valve depending on whether you are charging with the engine running or engine
stationary and if the A/C system is OFF or ON.
The display (2) will start from zero and will indicate the amount of refrigerant that has been
charged into the air-conditioning system. This function can be paused at any time, by pressing the
'STOP' key once, or twice, to cancel the function.
If the charge function has been paused, the amount of refrigerant that has been charged to that
point will be displayed, to continue the charge function press the 'START' key.
Once the present refrigerant weight has been charged, the charge function will automatically stop
and the display will indicate 'DONE'. The operator can return the machine to its initial state by
pressing 'STOP' key on the console.
After completion of refrigerant charge, the unit will automatically print the report of the amount of
refrigerant charged into the A/C system.

20
Conditions that will prevent refrigerant charging
-If there is little or no refrigerant in cylinder (12). The operator will not be able to
select the desired amount of refrigerant required.
-If the cylinder (12) valve is closed.
-If the hand manifold valve (4) is closed.
-If the A/C system service port Schrader valve is not depressed.
11. Automatic Cycle Procedure
In the Automatic cycle mode, all the operations (refrigerant recovering and recycling, recovered
oil discharge, evacuation, new oil injection and refrigerant charging) are performed automatically,
in one cycle.
Quantity of the refrigerant recovered, recovered oil, vacuum time, new oil injected and refrigerant
charged into the A/C system are printed at the end of each single operation.
