5. Preparing the machine for the first use
Perform the following steps to prepare the unit before the first use.
1. Remove the nylon wrapped and styrofoam insert behind the cylinder (12).
2. Check to ensure that all of the accessory
components are present:
- Cylinder (12)
- Adapter (17)
- Cylinder vapor hose (15) - blue
- Cylinder liquid hose with ball valve (16) – red
- Service hoses with quick couplers (5)
- User's manual
- Cylinder strap
3. Check that the cylinder (12) is already placed on the platform (11) and properly secured with
the strap provided. Unscrew two securing M6 bolts placed on each side of the platform basis app.
3-4 mm and LOCK them in place with nuts provided.

9
4. Check the vacuum pump oil level (8). The oil
level should be even with the line on the vacuum
pump sight glass when the pump is not running.
5. Power up (19) the unit. The unit will perform
a lamp test, whereby all LED displays are
illuminated. This will enable the operator to
determine if any displays have failed.
6. After the sequence has been completed, the
display (2) will indicate FILT - 99Hr. This is the
number of hours left before equipment servicing
is required.
7. Now the display will show the amount of
refrigerant in the cylinder (12). If the cylinder is
delivered empty, display should indicate app.
0kg of refrigerant in the cylinder.
8. Mode Selection. To select a mode of
operation, press either the "UP" or "DOWN"
arrow keys until the LED indicator (3) is beside
the desired function. Press 'START' key which
will cause the unit to enter the selected mode.
Any mode that has been selected can be exited
by pressing the 'STOP' key.
If a valid key was depressed, the unit will beep. If
an inappropriate selection has been made, i.e.
attempting to select a mode whilst another mode
is in operation, the unit will ignore the pressed
key and will not beep.

10
9. Check that both cylinder valves and liquid hose (16) ball valve are open.
LIQUID AND VAPOR HOSES MUST BE CONNECTED TO VAPOR AND LIQUID PORTS ON THE
STORAGE CYLINDERS. INCORRECT CONNECTION WILL CAUSE CHARGING TO BE VERY SLOW.
10. Attach the service hoses (5) on the unit. Carefully tight (with fingers only) knurled nut on

7. Refrigerant Cylinder (12) Filling Procedure
Connect suction (blue) service hose (5) on storage cylinder by using the brass adapter (17)
provided. Open cylinder valve, open service hose (5) quick coupling by winding the wheel
clockwise and finnaly open console hand valve (4). Low Pressure gauge (blue) should detect
refrigerant pressure from storage cylinder.
With "UP" or “DOWN” keys select the Recovery function. By pressing "START" key twice, the
unit will automatically start transferring liquid refrigerant from the storage cylinder to the unit
cylinder (12).
When the desired amount of refrigerant is transferred, close the storage cylinder valve and allow
the unit to recover the refrigerant from the service hose (5). Once the function is completed the
unit will display symbol "dOnE" and the amount of refrigerant transferred will be displayed in kg or
lb on main display (2).
Due to the safety features incorporated, maximum filling capacity for 27kg cylinder is 20kg
(10kg for 12kg cylinder).
The cylinder (12) may be taken to your refrigerant supplier and refilled. Do not allow the cylinder
to be filled above 80% of it's capacity.
WARNING:
- Do not allow the cylinder to be filled above 80% of it's capacity.
- 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.

8. Connecting to the Automotive A/C System
Use the service hose (5) quick couplings 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). If the system is equipped with a single service port, connect only the
appropriate 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.
Note: Console hand valves (4) need to stay closed in order not to allow the refrigerant to
enter the service equipment until the required function has been selected.
The unit 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.
Set the transmission in neutral, start engine
and turn the air conditioning on. Allow
pressure gauge needles to stabilize and
record the pressure readings.
Gauges reading may show particular
problem or associate to a possible
problems.

9. 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 unit
cylinder ready for re-use.
To initiate the Recovery mode, press the 'UP' key once, followed by 'START' on the console.
Display shows (- - - -). Now, there are two choices:
1. Press "START" key again to recover the whole amount of the refrigerant from the A/C system
or storage cylinder.
2. With "UP" or "DOWN" key to select desired quantity of refrigerant to be recovered from the a/c
system or storage cylinder. After the quantity selection, press "START" key.
Note: Open the hand valves (4) on the console to allow the flow of the refrigerant from the
a/c system into the unit before making the above selection.
During the recovery process, the Recovery mode indicator 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 unit will enter the recovery "PAUSE" mode. In this mode, the unit will shut down the
recovery function and pause for 3 min., which during this time the recovery mode indicator will be
ON constantly. The display (2) will indicate "PAUSE". During this function, the unit 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 and recover the rest of the remaining refrigerant.

15
If at the end of Recovery process a sufficient vacuum has been maintained, the unit will stop, the
display (2) will indicate '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 7 seconds. During “busy” time
machine will automatically drain recovered oil (separated from refrigerant) into recovered oil
vessel (9).
Conditions that will halt the recovery mode
1. Refrigerant cylinder (12) full. To protect the storage cylinder (12) 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 unit exceeds 25 bar (340 psi), the unit will stop
and display 'HigH - PrES'. The following can cause the above:
Cylinder (12) valves not open.
Restricted cylinder hose (16). Check the ball valves.
Excessive high ambience temperatures.
Excessive air in refrigerant into the cylinder (12).
Faulty pressure control.
In all the above circumstances, press the 'STOP' key to return to the machines initial mode.

16
10. Evacuation Mode
In the evacuation mode the air and moisture in the air
conditioning system is removed and exhausted to the
atmosphere. The evacuation mode runs for a predetermined
time selected by the operator.
To initiate evacuation mode, press the 'UP' 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.
(example value only)
Once the desired time has been selected press the 'START' key and the function will commence.
Note: During evacuation mode 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 unit has a unique function that if the evacuation function is selected and there is residual
refrigerant in the air conditioning system, greater then 0.5 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.
Note: 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 that may exist in the air- conditioning system. This is achieved
by monitoring the suction and discharge gauges.

17
11. New Oil Injection Mode
The purpose of the oil injection mode is to batch a user-defined quantity of refrigerant oil
from the graduate reservoirs on the unit to the vehicle air-conditioning system.
Important: The unit requires that the air conditioning system has previously been
evacuated to a maximum vacuum before this function can be carried out. Make sure you
have sufficient oil in the oil reservoir (10).
Keep hand valves (4) closed on the console. Open the ball valve on the oil reservoir (10) and note
the amount of oil being injected, by the graduations on the reservoir. Close the ball valve when
the correct amount has been injected.
Warning: If the oil reservoir (10) valve is not closed, excessive oil will be charged into the air
conditioning system, or the oil will be blown out of the reservoir when charging a system.
On A/C systems without discharge port, oil and UV dye can be carefully injected through suction
port only. That case, open both hand valves (blue and red) (4) on the console.

18
12. UV Dye Injection Mode
The purpose of the oil injection mode is to batch a user-defined quantity of UV Dye from
the graduate reservoirs on the unit to the vehicle air-conditioning system.
Important: The unit requires that the air conditioning system has previously been
evacuated to a maximum vacuum before this function can be carried out. Make sure you
have sufficient UV dye in the reservoir (21).
Keep hand valves (4) closed on the console. Open the ball valve on the UV Dye reservoir (21)
and note the amount of UV dye being injected, by the graduations on the reservoir. Close the ball
valve when the correct amount has been injected.
Warning: If the UV Dye reservoir (21) valve is not closed, excessive UV dye will be charged into
the air conditioning system, or the UV Dye will be blown out of the reservoir when charging a
system.
On A/C systems without discharge port, oil and UV dye can be carefully injected through suction
port. That case, open both hand valves (blue and red) (4) on the console.

19
13. Refrigerant Charge Mode
The purpose of the refrigerant charge mode is to batch a user-
defined weight of refrigerant into the air-conditioning system.
To initiate charging mode, press the 'UP' key three times (or DOWN once), followed by the
'START' key. Select the desired refrigerant amount by pressing the 'UP' key to increase or
'DOWN' key to decrease. The maximum refrigerant weight that can be set at this point is
determined by the actual refrigerant weight available in the cylinder (12).
(example value only)
Once the refrigerant charge weight has been set, press the 'START' key and open appropriate
hand valve depending on weather you are charging with the engine running or stationary (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.
Conditions that will prevent refrigerant charging:
- If there is little or no refrigerant in cylinder (12).
- If the cylinder (12) valve is closed.
- If the hand manifold valve (4) console is closed.
- If the A/C system service port Schrader valve is not depressed.

20
14. Automatic Cycle Mode
In the Automatic cycle mode, all the operations (Refrigerant Recovering and Recycling,
Recovered Oil Drain, Evacuation and Refrigerant Charging) are performed automatically
one after the other in ONE CYCLE.
Note: During AUTOMATIC mode hand valves (4) on the console must be open.
To initiate the Automatic cycle mode, press the “UP” or 'DOWN' key 4 times (display will show
AUTO) followed by 'START' key.
Set the vaccum time duration by pressing the 'UP' key to increase or 'DOWN' key to decrease.
Once the desired vacuum time has been selected, press 'START' key.
(example value only)
