Operation

Figure 7

Vacuum gauge (2): green zone (3), red zone (1)

When using the machine, check the flow control:

■ when the machine is operating, the pointer of the vacuum gauge must remain in the green zone (3) to ensure that the speed of the intake air does not drop below the safety value of 20 m/sec;
■ If the pointer is in the red zone (1) it means that the speed of the air in the vacuum hose is less than 20 m/s, and that the machine is not operating in optimal conditions. Shake or replace the filter.
■ during normal operation conditions, close the vacuum hose, the pointer of the vacuum gauge must switch from the green zone (3) to the red zone (1).

CAUTION!

The air speed in the vacuum hose must not be less than 20 m/s.

Condition indicated by the vacuum gauge pointer in the green zone (3).

CAUTION!

All machines can be used only with hoses whose diameters comply with the specifications in the "Technical Data" table.

CAUTION!

Consult the "Troubleshooting" chapter if faults occur.

Permissible number of starts per hour

The vacuum unit can be started a limited number of times per hour. An excessive number of starts could cause the motor of the vacuum unit to overheat and be damaged.

The starts must be equally spaced out over time.

Limiting valve

The limiting valve operates when the vacuum unit is used for long periods of time with the fi Iter or hose completely clogged (operation with the inlet closed).

These situations occur frequently when the vacuum unit is installed in a room other than the place of work. When the calibrated vacuum value is created on the valve, it opens to allow air to enter the impeller. This prevents the impeller from overheating and the electric motor from absorbing excessive power.

CAUTION!

The limiting valve has been calibrated by the manufacturer. Do not tamper with or change the calibration. Failure to comply with these instructions could jeopardize your safety. Moreover, such action would immediately void the EC declaration of conformity/incorporation issued with the machine.

At the end of a cleaning session

■ Turn off the machine and remove the plug from the socket.
■ Wind up the connection cable.
■ Empty the container and clean the machine as described in the “Maintenance, cleaning and decontamination” paragraph.
■ Wash the container with clean water if aggressive substances have been vacuumed.
■ Store the machine in a dry place, out of reach of unauthorised people.
■ Lock the castor brakes.
■ During transport and when not using the machine, close the vacuum inlet with the relevant plug (if equipped).

Maintenance, cleaning and decontamination

CAUTION!

Disconnect the machine from its power source before cleaning, servicing, replacing parts or converting it to obtain another version/variant.

• Carry out only the maintenance operations described in this manual.
  ■ Use only original spare parts.
  ■ Do not modify the machine in any way.

Failure to comply with these instructions could jeopardize your safety. Moreover, such action would immediately void the EC declaration of conformity/ incorporation issued with the machine.

CAUTION!

For maintenance procedures not described in this manual, please contact the manufacturer's technical support or sales network.

CAUTION!

To guarantee the safety level of the machine, only original spare parts supplied by the manufacturer should be used.

CAUTION!

The precautions described below must be taken during all maintenance operations, including cleaning and replacing the primary and absolute filters.

■ To allow the user to carry out the maintenance operations, the machine must be disassembled, cleaned and overhauled as far as is reasonably possible, without causing hazards for the maintenance staff or other people. The suitable precautions include decontamination before disassembling the machine, adequate filtered ventilation of the exhaust air from the room in which is disassembled, cleaning of the maintenance area, and suitable personal protection.
■ The external parts of the machine must be decontaminated by cleaning and vacuuming methods, dedusted or treated with sealant before being taken out of a hazardous zone.
■ All parts of the machine must be considered as contaminated when they are removed from the hazardous zone and appropriate actions must be taken to prevent dust from dispersing.
■ When maintenance or repair procedure are carried out, all the contaminated elements that cannot be properly cleaned, must be eliminated. These elements must be disposed of in sealed bags in accordance with applicable regulations and local laws on the disposal of such material. This procedure must also be followed for filter disposal (primary and absolute filters).

■ Compartments that are not dust-tight must be opened with suitable tools (screwdrivers, wrenches, etc.) and thoroughly cleaned.
■ A check must be carried out by the manufacturer or the personnel of the same at least once a year. For example: Check the air filters to find out whether the air-tightness of the machine has been impaired in any way and make sure that the electric control panel operates correctly.

Filter cleaning

Primary filter cleaning with manual system

3. Filter cleaning solenoid valve 3
4. Filter cleaning solenoid valve 4
5. Cartridge container pressure switch

When it is necessary to vacuum very fine dust continuously without stopping to clean the filters, the Manufacturer provides the machine of a multi-cartridge filtering system.

The unit is equipped with a fully automatic electropneumatic device to alternately clean the filtering cartridges, which guarantees continuous service.

Electric panel, powered with a 24V rating, is complete with cyclic timer to regulate the following times:

T1 Filter cleaning time

Opening time of the solenoid valve for backwashed air exhaust into the cartridge.

The shorter the time, the more energetic the cleaning action will be.

T2 Work hold time

Time between one cartridge cleaning operation and the next.

T3 Time between cleaning cycles

Time between one cleaning cycle and the next.

Check the arrows on the knobs of the timer for the exact regulation.

Replace the filter element if the vacuum gauge pointer stays in the red zone even after the filter has been shaken (see "Primary and absolute filters disassembly and replacement").

[ NOTE ]

If the indicator is still in the red area. The vacuum hose or one of the accessories may be clogged, and not the filter. Clean these parts if this is the case.

Pressure inlet in the tank:

■ Min. 4 bar;
■ Max. 6 bar.

A pressure gauge is installed near the filter.

Install an ON-OFF device (ball valve or similar) in the air supply line to easily performed the maintenance procedures.

The filter must be powered by a specific branch that can be disconnected independently.

The installer must properly fix the compressed air hoses and provide appropriate protection against sudden detachment of the hoses.

Compressed air must be:

1. Clean - i.e. free from waste that could damage the solenoid valves.
2. Dehumidified - the filter tank is equipped with a cap for discharging the condensation. However, the use of a condensate separator should be considered.
3. Deoiled - oily substances in the air can cause premature and irreversible clogging. Use filters that keep the air always clean and deoiled.

Empty the pipes before connecting the compressed air to the filter.

Container and dust bag cleaning

Emptying the container

Before proceeding with these operations, turn off the machine and remove the plug from the power socket. Check the machine filtration class.
