6Switching ON the Machine
Switch on machine power switch, the machine will
display the number of hours left before the
maintenance service is required.
Followed by self purge and hose evacuation (if
necessary). This special function will prevent non-
condensable (air) to be pushed in to the cylinder,
therefore maintaining maximum refrigerant purity.
Once this function is completed, the main menu is displayed on the LCD.

9Storage Cylinder Filling Procedure (Refrigerant Transfer)
The purpose of the Refrigerant Transfer mode is to transfer new refrigerant from a storage cylinder
to the machine cylinder.
The machine refrigerant cylinder which is situated behind the cylinder cover is supplied empty of refrigerant.
Note: The cylinder is evacuated by the manufacturer.
There are various types of new refrigerant cylinders which are in the market, refillable and disposable
cylinders.
Whenever refrigerant is transferred from either type of cylinder, must always be transferred liquid state in to
the machine.
Using a refillable cylinder to transfer refrigerant (see figure 1 for correct connection
procedure)
Keep the cylinder sitting upright, connect the suction (blue) service hose to new refrigerant cylinder liquid valve
by using the brass adapter provided, open liquid valve on storage cylinder (please note, all cylinder valves are
marked with liquid and vapour on the valve hand wheel), open suction service hose quick coupling >>>
Using a disposable cylinder to transfer refrigerant (see figure 2 for correct
connection procedure)
Connect the suction (blue) service hose to a new refrigerant cylinder valve by using the brass adapter
provided. Turn cylinder upside down for liquid delivery, open the valve on the cylinder, open suction service
hose quick coupling >>>

Step 1 - Touch refrigerant recovery icon
Step 2 - Touch compressor icon
Step 3 - Touch suction (S) icon
Step 4 - Touch weight icon
Step 5 - By using the keypad select the desired
amount of refrigerant to be transferred into the
machine cylinder and touch Enter.
Step 6 - Touch confirm icon and press the Start
button on the panel.
NOTE : If you wish to transfer the complete
amount of refrigerant from the new refrigerant
cylinder in to the machine cylinder go directly
from Step 3 to Step 7.
Step 7 - Touch 100% icon , touch the confirm icon
and press the Start button (See flow chart below).

10 Connecting and testing the A/C system
Use the service hose quick 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 (grease or dust).
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 displays will indicate a pressure.
The unit digital displays (suction & discharge) are important and important instruments.
The digital displays indicate the working pressure of the suction and the discharge side of the A/C system. The
pressures are displayed in Metric or Imperial system depended of the user selection.
The operator should have basic understanding between gauge reading and air-conditioning system normal
operating pressures, in order to correctly diagnose any possible system malfunction.
Above the digital displays is a bar graph which gives an estimation of good, fair or bad working pressures of
the A/C system. The black segment on the bar graph is related with the working pressure readings. The bar
graph colour coding is only indication.

11 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.
Step 1 - Touch the Recovery Icon
Step 2 - Touch compressor icon
Step 3 - Select the desired A/C service port or
ports. Recovery process is faster when both
suction and discharge ports are selected.
Step4 - To recover the complete amount of refrigerant
from the A/C system, touch 100% icon, touch the confirm
icon and press the Start button to start the recovery
process.
Note: To recovery desired quantity of refrigerant to A/C system touch weigh icon. By using the keypad select
the desired amount of refrigerant, touch Enter icon, touch Confirm icon and press Start button to start the
recovery process.

WOW! Coolius 2700BT
- 19 -
Before recovery process start, the machine will self purge and
evacuate the service hoses (if required).
During the recovery process the machine will display the amount of
refrigerant being recovered. this process can be paused by
depressing Stop button and abort the function totally by depressing
the Stop button again or restart the process by pressing the Start
button.
Once the machine has reached a vacuum of -0.25 kPa it will enter
into recovery pause for duration of 3 minutes to allow for any
remaining refrigerant in the A/C system (if any) to boil off.
If the pressure in the A/C system increases above 0 kPa the machine
will automatically return in to recovery re-run to the remove the rest
of the refrigerant which has boiled off in the A/C system.
If recovery re-run is initiated again the machine will pull down to a
further vacuum of -0.30 kPa and then it will pause again for a
further 3 minutes.
If after the 3min. pause there is no further pressure increase in the
A/C system the machine will drain and measure the recovered oil (if
any).
The display will show the total amount of refrigerant recovered and
oil (if any). This will be displayed until the stop button is depressed
which then machine will display main menu again ready to select
another function if required.

12 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.
Step 1 - Touch the Evacuation Icon
Step 2 - Touch the Time Icon
Step 3 - By using keypad select desired vacuum
time and touch Enter icon to confirm.
Step 4 - Touch compressor icon
Step 5 Select the desired A/C service port or ports.
Evacuation process is more efficient when both
suction and discharge ports are selected.
Step 6 - Touch Leak Test icon
Step 7 - Touch confirm icon if you want to select
leak test, touch X icon to abort leak test under
vacuum.
Step 8 - By using keypad select leak test time and
touch Enter icon to confirm.
