Cooltech equipment consists of 3 large blocks: an electronic block - for control of all inputs and
outputs of the equipment, a refrigeration block –for cooling the hot part of the peltiers and a
vacuum block - for stopping blood circulation in the treated area, avoiding heating the area for
better results. Each of these blocks is described in more details below.
Electronics:
The electronic block consists of 2 CPUs: the Main and TFT control board.
Main CPU TFT control board
Main CPU is located inside the electic cabinet of the equipment (on the left side, viewed from the
front), while TFT control board is mounted underneath the display.
TFT control board is responsible for displaying the necessary images on the screen, analyzing
and informing the Main CPU, when the user enters any data and commands on TFT.
All images, graphics and active zones for the screen are stored on a microSD inserted in TFT
control board.

This memory card should have maximum capacity of 2GB and format to FAT32 clouster 4096.
On the microSD are stored only 3 '.ars' files: PrjAreas.ars, RrjIcons.ars and PrjImages.ars. If exist
other files, may appear an error while the software is being loaded.
Main CPU is responsible for controlling temperature, vacuum and refrigeration of each applicator,
reading the information from all inputs (sensors, switches, power supplies, resistors ect.) and
activating any of outputs (pumps, peltiers, electrovalves ect.) in different moments and also
sending the relevant feedback to the screen.
The following figure shows all cables connection to Main CPU

General considerations for cleaning and maintenance:
- For safety reasons, before cleaning the equipment, it is recommended to disconnect the
power cord from power socket.
-For methacrylate surfaces, pay great attention in the use of cleaning products. If this
material comes in contact with substances such as alcohol, solvents, ammonia or other
aggressive products (thinners, acetone ...), it reacts forming "cracks", which are not visible
immediately but in the next days.
- To clean this material, it is recommended to use specific methacrylate products such as
"Vetril" or use a well squeezed cloth or soft paper after being soaked in water with diluted neutral
soap.

- It is recommended to clean and sanitize the applicators of the equipment after each
treatment. To do this, remove the product residues (gel) deposited in the applicator, clean and
disinfect the applicator before using again. Do not use products containing alcohol.
- For outside cleaning of the casing, dry thoroughly using synthetic fabrics before starting a
new treatment.
-Do not immerse the applicator in any liquid
1.2.1 - External tanks Cleaning
To clean external tanks, the tubes connecting each tank to the equipment must be disconnected.
Press the grey clips of the connectors and pull them out, in this way the tank will be totally
independent from the equipment.
Once the connectors have been removed, take the tank out of its holder carefully. To make
complete cleaning, disconnect the air filter from the tank and the hose.
Remove the cap from the tank and wash both parts with plenty of water.
Then close the tank again, install the filter (explained later), put it back inside its holder and
connect the tubes in their corresponding inputs. Make sure that it is properly placed in the holder
and that the tubes are not bent. The position of the connectors is indicated with colors (only on
some models). Checked carefully that the tank is well closed, otherwise the equipment will not
operate correctly and will not reach the desired vacuum.
1.2.2 - Air filter cleaning (ventilation)
At the bottom of the equipment there is an air filter to prevent entering dust iside the unit. To
remove the filter, just pull it. This filter should be cleaned once every month.
To clean it, use a vacuum cleaner or shake it. The filter should be changed once a year. To
supply these filters, contact the manufacturer.
Replacement of antibacterial vapor filter
When the filter is dirty and the suction power is insufficient in its corresponding applicator,
proceed to replace it.
The bacterial filter is connected to two tubes, one goes from the filter to the equipment
connector, the other from the filter to the tank. Replace the filter by disconnecting the pipes by
pulling slightly and progressively. Connect the new filter in the same position as the old one,
matching the color band of the tube connected to the equipment with the color band incorporated
on the filter.
1.2.3 - Applicator internal cleaning
It is necessary to perform periodically a cleaning of the applicators, because of the gel that is
going inside and clogging the hose during the treatments.
This proplem leads to a progressive loss of the suction capacity of the applicator, reaching the
point that the hand piece stops sucking comletely (totally obstructed line).
The periodicity of cleaning is related to the number of treatments and the amount of gel that is
used.
Important: Before start cleaning, disconnect the equipment from the power socket.
To clean an applicator, disconnect the tube in the back of the equipment that has a red color
band, connecting the tank with the machine.
Important: Perform the operation with the tank corresponding to the applicator.

Press the grey clip of the female connector to disconnect the tube and then pull slightly and
progressively from the tank.
During the cleaning process, it is recommended to keep the applicator on higher position so that
the liquid injected with the cleaning tool supplied with the equipment, not return.
Then insert the end of the cannula tube into the internal input of the applicator and inject the
distilled water contained in the cannula. Remove the tube from the hole. Fill the cannula with air
and inject it in the same way in order to clean thicker gel residues.
Repeat these operations (first distilled water and then air) until flows clean water on the back of
the equipment.
Important: Be careful during the cleaning process not to overfill the tank on the back of the
machine, corresponding to the applicator being cleaned, otherwise will damage the paper filter.
Always empty before filling.
At the end of the cleaning, perform several more operations with air only, to blow out any water
left in the hose.
Then empty and clean the tank. To do this, remove the cap and wash out all the gel residues.
Replace the cover.
The tank should be closed properly: carefully tighten all tank clips (otherwise will be observed
vacuum drops during the treatment).
Once the applicator or applicators have been cleaned, as well as the tank, proceed to reconnect
the tanks, as explained in section 2 of the equipment installation. Remember that tanks have a
single connecting position. Take into account that the color band of tank and equipment match
and the paper filter is on the right of the reservoir.
Codes, enabling access to different functions, specific settings and parameters of the equipment, that
could be monitored and modified. To do this enter the code screen, then enter the relevant code and
press 'Enter'.

Before starting the software update of the equipment, it is necessary to access the Main CPU. Remove
the left cover of the equipment by unscrewing the 3 rear screws, as shown on the image1 and access to
the electro cabinet (Image2):
Once the PCB of the equipment is located, connect the AVR programmer to the PCB. Pay attention on
the connector position:
Start the previously installed Atmel Studio, turn the equipment on and follow the steps:

1. Select "Tools -> Device Programming" as shown in the image:
2. Configure the necessary data for the programming:in the "Tool" drop-menu select "Atmel-ICE" and in
the drop-menu "Device" select "ATmega128". Then press the "Apply" button.
3. Before programming it is necessary to read and save the EEPROM information for the equipment. To
make this procedure, go to the "Memories" tab and click the "..." button in the EEPROM section:

4. Specify the location for saving the file and its name. Then click the "Save" button and finally click the
"Read" button:
5. Click the "..." button as shown in the image and select the appropriate Cooltech program (.hex file)
in the Flash section. Then select the EEPROM file previously saved. Click on the "Program" button in
the Flash section:
