If you need to change the language or to increase / decrease the display contrast, press
the two keys with icons “ “ contemporaneously and all available languages will appear
on the display.
Slide the arrow keys “ “ until the desired choice has reached, then press the “en key to
validate the preference. e same procedure must be made to increase or decrease the
brightness of the display, dealing on the bar that appears on the display. en press “ente

CONNECTION OF 5 - 10 - 12 - 40 KG. CYLINDERS
Preparation of the base
1. Screw the 1/4” F. Sae
adapter for 1 kg. cylinder to
the base
1. Double valve cylinder
2. Single valve cylinder
Use the cylinder in vertical position if
the valve has a dual output, Blue - Red.
In this case, connect the hose to the Red
output to use the refrigerant uid in the
liquid phase.
1. Open the gas tap
2. Turn the cylinder upside-down to use
the refrigerant uid in the liquid phase.
SUGGESTIONS FOR THE CHARGE BY PRESSURE PROCEDURE
If you use a cylinder bigger than 2 kg., the “charge by pressure” is recommended.
If you know the exact quantity to ll inside the system, it is possible to reduce the charging time,
using a 80 kg. scale (optional at page 18).
Aer vacuum procedure, open the GAS tap to make charge procedure without disconnecting
from the system.
It is at the operator discretion to keep the IDEA TRONIC switched on or switched o.
1. Screw the 1/4” M. Sae
nipple to the adapter
1. Connect the 1/4” Sae M.
hose to the cylinder

SCREEN 2
CHOICE OF REFR. FLUID – BT, TN, AC AND CHARGE METHOD
Set up the kind of refrigerant uid and the charge method, sliding the arrow keys “ “
and pressing “enteraer choosing the convenient option.
N.B.: for some refrigerant uids it is possible to select TN (positive temperature) suitable
for refrigeration cabinets for drinks etc., BT (negative temperature) suitable for domestic
refrigerators etc. or AC, suitable for air-conditioning systems.
You will then be asked to select the opportune charge method, it means by weight, if you
work with 1 or 2 kg. cylinders screwed on IDEA TRONIC, or by pressure, if you do not
know the quantity of refrigerant uid to ll inside the system and/or if you use cylinders
bigger than 2 kg.

SYSTEM CHECK
In this screen you can analyze the state of the system on which you will operate; the
display will show the following options:
1) Adequate gas
2) Too much gas
3) Problems
N.B.: e system check procedure must be carried out with the system switched on
(compressor running) after having waited for a few minutes so that the internal
pressure has stabilized.

VACUUM
If you need to perform the vacuum procedure, slide the arrow keys “” up and down
and conrm the “VACUUM” option by pressing the “entkey.
Open the vacuum tap and switch on the pump, then press “ente key.
e electronic bar will start to empty out until reaching -0,8 Bar; aer that a green
LED will light up if any leak is detected and so you can set the desired time up to 60
minutes.
On the contrary, if the red LED lights up, it means that the system on which you are
working has some leaks. Press “entekey and go back to vacuum menu.
Switch o the system, repair the leak and repeat the process from the beginning.

CHARGE BY WEIGHT
If you selected the “charge by weight” option in “SCREEN 2”, proceed with the charge,
screwing the refrigerant uid cylinder on the holder of the IDEA TRONIC device.
Set up the refrigerant gas charge in grams which you need to ll inside the system, by sliding
the “ ” keys.
en press the “ent key and the empty electronic bar will appear on the display.
Open the refrigerant gas tap very slowly and the empty electronic bar will start to gradually
ll up until the preset quantity visible at the end of the bar is reached.
Guide the lling procedure with the hand and close the refrigerant gas tap quickly, avoiding
to release a greater quantity of uid than preset.
is charge procedure can be performed with the system o; anyway, if at some point you
are unable to ll the preset quantity (especially in small systems), you need to switch it on
for a few minutes.
N.B.: e refrigerant uid ends during the charge procedure. If by any chance the refrigerant
uid contained in the cylinder ends before nishing the charging procedure, the written
word “empty cylinder” will appear on the display.
Press enterkey and replace the cylinder. e system stores the refrigerant gas quantity already
lled, so complete the charge.
ATTENTION: the written word “empty cylinder” can also be shown if the refrigerant uid
does not enter inside the system. Switch on the compressor to guide the lling.
N.B.: Once the gas charge procedure has been completed, if you desire to “check the system”,
let the equipment running for at least 15 minutes, then proceed.
ATTENTION: ACCIDENTALLY TOUCHING THE REFRIGERANT CYLINDER DURING
THE CHARGE MAY INVALIDATE THE PROCEDURE DUE TO THE POSSIBLE RESETTING
OF THE DEVICE.

Picture 2: Press enter key with the
compressor running and open

Close the tap when the charge is
reached.

CHARGE BY PRESSURE
If you selected the “charge by pressure” option in “SCREEN 2”, aer entering in the
CHARGE MENU, connect the cylinder located on the floor to the IDEA TRONIC
device through a exible hose.
If the cylinder does not have the dip tube, perform the charge turning the container
upside-down to use the liquid refrigerant uid part.
Switch on the system to be repaired, ensure that the compressor is running, then press
the “ent key.
At this point, the empty electronic bar will appear on the display (Picture 1),
through which the operator will visualize the status of the system charge.
e procedure ends when the bar will be completely lled up.
Open the refrigerant gas tap very slowly (liquid phase) and close it as soon as the
electronic bar will be completely lled up and on the display will appear the “wait for
compensation” written words (Picture 2).
Keeping the refrigerant gas tap closed, let the equipment running for a few minutes to
allow the refrigerant uid to stabilize inside the system. In the meantime, with the
compressor running, the electronic bar will automatically empty from the top.
Repeat the operations for a few times until the Bars shown at the end of the electronic
bar are the same (or very close) to those indicated above xxx Bar Bar xxx
At this stage the IDEA TRONIC device will emit an acoustic signal indicating that the
performance is completed (Picture 3).
Use with 5 - 12 - 40 Kg. cylinders

RECOVERY OF THE REFRIGERANT FLUID
If you need to perform the refrigerant fluid recovery operation, you must use the 3
ways adapter supplied as optional (Picture 2), which connects the IDEA TRONIC
device, the recovery unit and the vacuum pump simultaneously.
Once connected all equipment, it will be then possible to perform all operations
without never disconnecting them; in fact, you will be able to operate both with one
or the other device, according to the opening direction of the tap. If the tap is
positioned at the center, the transfer will be closed from both sides.

CHECK OF SPECIAL SYSTEMS
Idea Tronic has been developed in order to
operate in traditional equipment and condi-
tions.
The diagnosis displayed on the screen,
ADEQUATE GAS, TOO MUCH GAS etc. has
been calculated on an average operating
process for each refrigerant fluid.
If the installation of the circuit has been
effected in abnormal conditions (poor
ventilation, different length of hoses, etc.),
the working pressures may be different,
altering the correct reading of the hand-held
equipment.
In these special situations it is possible to
connect a gauge for a double reading , as
shown to the side.
