INFO A safe and effective capture of the welding fumes is only possible if there is enough extraction capacity. The more clogged the filters the narrower the air flow, with a reduction of the extraction capacity! The acoustic alarm beeps as soon as the extraction capacity falls down below the minimum value. At that point, the filter needs replacing! The same happens even if the manual damper in the extraction hood is too closed, significantly reducing the extraction capacity. In this case, open the manual damper.

Correct positioning of the capture hood
The articulated arm with its capture hood (provided with the unit) has been conceived to make positioning and approaching the source of fumes very easy and dynamic. The capture hood remains in the required position thanks to a multidirectional joint. In addition, both the hood and the arm can rotate 360°, allowing the suction of fumes in almost any position. Correct positioning of the capture hood is an essential prerequisite in order to guarantee efficient extraction of welding fumes. The following figure shows the correct positioning.

• Position the articulated arm so that the capture hood is positioned transversely to the welding point, at a distance of approximately 25 cm.
• The capture hood must be positioned in such a way as to allow efficient extraction of welding fumes, according to their direction as the temperature and the suction radius vary.
• Always position the capture hood near the relevant welding point.

WARNING In case of incorrect positioning of the capture hood and poor extraction capacity, an efficient extraction of the air containing dangerous substances cannot be guaranteed. In this case, the hazardous substances could penetrate the user’s respiratory system, causing damage to health!

Start of the unit

• Connect the unit to the mains supply; notice the data indicated on the rating plate.
• Switch ON the unit using the yellow-red main switch.
• The control panel is now active, press the ON key on the panel for 3s.
• The fan starts running and the green light indicates that the unit is functioning correctly.
• Finally, always adjust the capture hood in position according to the work process.

Start of the unit with automatic START-STOP device
The unit can be equipped with an automatic START-STOP electronic device which automatically starts and stops the extraction according to the actual operation of the welding unit. The device is installed and activated only and exclusively by qualified personnel of Aerservice Equipments, so it is necessary to order from the beginning the unit with this device.

The unit with automatic start and stop function has a special clamp on the side of the unit and also specific indications in the display.

After having turned on the main switch of the unit, the pcb will turn on giving the following information:

• Software version installed
• Name and p/n of the unit
• Then the following information will be shown in the display: START-STOP ACTIVATED.
• The extraction LED  will be flashing.

In this mode the unit is ready to work and it is sufficient to start welding to activate the fume extraction. The unit is already sed to stop extracting after 1 minute from the last welding cycle.

MANUAL OPERATION
It is possible to start the unit manually by pressing the ON button for a few seconds.
The message: MANUAL START ACTIVE will appear. The operation of the filter unit will be active until the OFF button is pressed. After turning off the extraction, the unit will automatically return to the automatic Start / Stop mode. When the automatic Start / Stop device is provided on the unit, the clamp for the ground cable of the welding unit is also installed on the side of the filter unit.

To ensure proper operation of the automatic Start / Stop device, it is essential that the ground cable of the welding unit is placed on the metal cabinet of the filter unit and locked in position by the special clamp. Check that the ground cable is well in contact with the metal cabinet of the unit, as shown in the figure.

The unit does not require any specific maintenance, except for the replacement of the filters if necessary and the inspection of the articulated arm. Follow the warnings given in paragraph 2.5 “Safety warnings for maintenance and troubleshooting”.

Replacement of filters
The lifetime of the filters depends on the kind and quantity of particles extracted. To optimize the life of the main filter and to protect it from coarser particles, all units are provided with a pre-filtration stage. It is advisable to periodically replace prefilters (consisting of 1 or 2 filters depending on the version), depending on the use, for example every day, week or month, and not to wait for complete clogging. The more are clogged the filters the narrower is the air flow, with a reduction of the extraction capacity. In most cases it is sufficient to replace the prefilters. Only after several replacements of prefilters will the main filter also need to replacing .

• INFO The acoustic alarm beeps as soon as the extraction capacity falls down below the minimum value.
• WARNING It is forbidden to clean fabric filters (all kinds): corrugated, pocket and cartridge filters. Cleaning would cause damage to the filter stuff, compromising the function of the filter and leading to escape of hazardous substances into the ambient air. In case of a cartridge filter, pay particular attention to the filter seal; only if the seal is free from damages or imperfections it is possible to guarantee a high level of filtration. Filters with damaged seals shall always be replaced.
• WARNING Skin contact with dust and other substances lying on the unit can cause irritation to sensitive persons! Danger of serious damage to the respiratory system! To avoid contact and inhalation of dust, it is recommended to use protective clothing, gloves and a mask with a FFP2 class filter according to EN 149 standard. During cleaning, prevent dangerous dust from being diffused in order to avoid damage to the health of other persons. To this purpose, carefully insert the dirty filters inside bags with sealing and use an industrial vacuum cleaner for dust with efficiency class “H” to suck up any dust dropped during the filter extraction phase.

3. Instructions for UNI 2 E version

   • Use only original replacement filters, as only these filters can guarantee the required filtration level and are suitable for the unit and its performance.

   • Turn off the unit by the yellow-red main switch.

   • Secure the unit by pulling out the plug from the mains, so that it cannot be accidentally restarted.

   • Open the inspection door on the side of the unit.

   • a) Replacing the prefilter

   • – Carefully remove the metal prefilter and the intermediate filter, in order to avoid any lifting up of dust.
     – Carefully place the filters in a plastic bag, while avoiding any dust diffusion, and close it, for example with cable ties.
     – Suitable plastic bags can be supplied by Aerservice Equipments.
     – Insert the new filters in the guides making sure to respect the original order.

   • b) Regeneration of the electrostatic filter
     INFO The electrostatic filter of the unit UNI 2 E does not need replacing and can be regenerated. A specific washing procedure allows the filter to be cleaned and re-used.
     WARNING Skin contact with dust and other substances lying on the filter may cause irritation to sensitive people! Danger of serious damages to the respiratory system! Danger of serious eye damages during washing! To avoid contact and inhalation of dust or splashes of rinsing liquid, it is recommended to use protective clothing, gloves, a mask with a class FFP2 filter according to EN 149 and protective goggles for the eyes.

   • Disconnect the electric power connector from the filter.

   • Carefully remove the electrostatic filter, avoiding any lifting up of dust.

   • Extract the pre-filter incorporated in the electrostatic filter by lifting it for about one centimeter and extract it as shown in the figure.

   • Provide:

     • A plastic or stainless-steel tank with decanting bottom;
     • Rinsing liquid, available from Aerservice Equipments: p/n ACC00MFE000080;
     • Running water.

   • Use a stainless-steel frame to keep the filters off the bottom of the tank and allow decanting of sludge.

   • Pour lukewarm (maximum 45 ° C) or cold water. Add the diluted rinsing liquid according to the proportions shown on the label.

   • Dip the electrostatic filter in the tank, let it soaking for the time indicated in the instructions or until the dirt has completely dissolved from the cell.

   • Take up the filter, let it drip over the tank, rinse thoroughly under running water, taking care not to break the ionization wires.

   • Let the filter dry by keeping it raised from the floor with wooden strips or in a dryer with a maximum temperature 60° C.

   • Make sure that the electrostatic filter is clean and dry, then insert it in the guides inside the unit.
     INFO Some alkaline-based rinsing liquids can leave residues on the surface of the blades and isolators, which cannot be removed by simple rinsing and which result in voltage losses and therefore in less efficiency (up to 50%) of the electrostatic cell in case of ambient humidity. To remedy this effect, dip the cell in an acidulated bath for a few minutes and then rinse it again. Wash the pre-filter in the same way, taking care not to damage it by bending it or by weakening the filter mesh. The Manufacturer cannot be held liable for any breakdowns, malfunctions or shorter lifetime if maintenance is not carried out according to the present provisions.

   • c) If active carbons filters are provided, proceed as follows:

   • Open the air grids on both sides of the cabinet.

   • Carefully take out each filter avoiding any dust diffusion and place it in a sealed plastic bag.

   • Insert the new filters in the guides behind each grid and fasten again with the screws.

   • d) Once the filters have been replaced, proceed as per the following steps:

   • Close the inspection door and, depending on the model, check that it is completely closed and that the sealing gasket is positioned correctly.

   • Reinsert the plug into the mains socket and turn on the yellow-red main switch.

   • Reset alarms as indicated under point 7.4.

   • Dispose of the dirty filters according to the regulations in force locally. Ask the local waste disposal company for the relevant waste disposal codes.

   • Finally clean the surrounding area, e.g. with an “H” class industrial vacuum cleaner for dust.

Digital control panel: alarms and alarm reset
The mobile air cleaner is equipped with a pc board for the control and setting of all functions. Picture no. 1 shows the front panel where the user can set and read data.

Alarms are managed by the software in the following way:

• FILTER 80%: it turns on after 600 hours of operation to indicate that an overall check of filters is necessary (if not cleaned or replaced before) and of the unit as well, to verify if it operates correctly.
• FILTER EXHAUST: it turns on when the filter pressure differential gauge detects a specific difference value (set by the Manufacturer) between the inlet of dirty air and the outlet of clean air on the filter.

In addition to the visual alarm on the control panel, the unit is also equipped with an acoustic signal generated by a buzzer. From version 00.08 it is possible to deactivate the acoustic signal and keep only the lighting alarm.
On the pc board there are the following menus:

• TEST MENU
• USER MENU
• ASSISTANCE MENU
• FACTORY MENU

When the Filter Exhaust alarm turns on, it is necessary to replace the filters as indicated under point 7.3 and to reset alarms in order to restore normal operation. To carry out the reset it is necessary to enter the USER menu. To enter the User menu just press once the button: central circle (O). Then the unit will request a password, which is the following key sequence: central circle (O) + central circle (O) + central circle (O) + central circle (O) + central circle (O) + central circle (O). Once you have entered the menu, scroll down (↓) to the third position ALARMS RESET. Press the central button (O) to go in and then type the following key sequence: arrow down (↓), arrow down (↓), arrow up (↑), arrow up (↑), circle (O), circle (O). At this point the alarms are reset and all settings return to zero.  Remember that alarm reset is linked with the maintenance, cleaning or replacement of the filters. The Manufacturer cannot be held liable for any breakdowns, malfunctions or shorter lifetime if alarms reset and maintenance are not carried out according to the present provisions. Aerservice Equipments provides the unit with all alarm functions activated. Any deactivation of alarm is not attributable to the Manufacturer but to interventions carried out by the user or, eventually, by the dealer. Aerservice Equipments recommends not to turn off any alarm, in order to maintain a high level of control over the unit and the maintenance of filters and to safeguard the performance of the unit and the health of the user. Inside the USER MENU there is also the FIL.BUZ.ALERT. function, about the alarms with buzzer. It is possible to set three levels of this functions, as follows:

• NO: the buzzer acoustic signal is not active.
• EXHAUST: the buzzer acoustic signal is activated by the filter pressure differential gauge.
• DIRTY/EXHAUST: the buzzer acoustic signal is activated both by the filter pressure differential gauge and by the internal hour meter set by the factory.

WARNING It is strictly forbidden to reset the alarms without having performed the necessary maintenance! Aerservice Equipments is exonerated from any responsibility if these instructions are not respected.
