Maintenance, cleaning and decontamination
WARNING!
To guarantee the safety level of the vacuum cleaner, only original spare parts supplied by the manufacturer should be used.
WARNING!
The precautions described below must be taken during all the maintenance operations, including cleaning and replacing of the main and HEPA filters.
- To allow the user to carry out the maintenance operations, the vacuum cleaner 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 vacuum cleaner, adequate filtered ventilation of the exhaust air from the room in which it is disassembled, cleaning of the maintenance area and suitable personal protection.
If the vacuum cleaner belongs to the M or H class, the external parts 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 vacuum cleaner 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 when the filters are eliminated (main, HEPA and downstream filters).
Compments that are not dust-tight must be opened with suitable tools (screwdrivers, wrenches, etc.) and thoroughly cleaned.
Translation of original instructions
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 vacuum cleaner has been impaired in any way and make sure that the electric control panel operates correctly.
WARNING!
In particular, on Class H vacuum cleaners, the filtering efficiency of the vacuum cleaner must be checked at least once a year, or more often if required by national legislation. The test method for checking the filtering efficiency of the vacuum cleaner is indicated in standard EN 60335-2-69, par. AA.22.201.2. If the test isn't passed, it must be repeated after the class H filter has been changed.

Motor cooling fan inspection and cleaning
WARNING!
These operations can only be carried out by trained and qualified personnel
Periodically clean the motor cooling fan to prevent the motor from overheating, especially if the vacuum cleaner is used in a dusty place. (See Fig. 5)
Tightness inspection
Hoses check
Make sure that connecting hoses (1, Fig.17 for CTT models and 2, Fig. 17 for CTS models) are in a good condition and correctly fixed.
If the hoses are damaged, broken or badly connected to the unions, they must be replaced.
When sticky materials are treated, check for possible clogging along the hose (3, Fig. 17), in the inlet and on the baffle plate inside the filtering chamber.
Scrape inlet (3, Fig. 17) from the outside and remove the deposited waste as indicated in figure 17.
Filtering chamber tightness check
If the gasket (1, Fig. 18) between the container and the filtering chamber (3) fails to guarantee tightness:
Loosen the four screws (2) that lock the filtering chamber (3) against the vacuum cleaner structure.
- Allow the filtering chamber (3) to lower down and tighten the screws (2) once it has reached the tightness position.
The gasket must be replaced if it is torn, cut, etc.
Replace the gasket (1) if the degree of tightness is still not optimum.
Separator cleaning and replacement (optional)
[NOTE]
If there is only a dust deposit on the separator (3, Fig. 19) allow the dust to drop through the central hole.
The separator (3, Fig. 19) should first be disassembled in order to be perfectly cleaned:
Use the lever (1) to remove the cover (2) together with the primary filter.
Unscrew the two screws and remove it from the container.
Replace the part if it is excessively worn.
Assemble the components in the reverse order of disassembly.
Belt tensioning and replacement (CTT series)
Figure 21
WARNING!
When replacing the belts, only use genuine spare parts or spare parts with the same characteristics as the old ones.
WARNING!
These operations can only be carried out by trained and qualified personnel
WARNING!
After about 1 hour of operation, check belt tensioning again.
It is very important that the transmission belt is installed with the correct tension, in order to optimize its performance and life.
To obtain the correct transmission belt tension, use the following method:
Loosen the four adjusting plate (1) fixing screws.
Loosen the nut (2) and operate on the screw (3) to adjust the transmission belt (4) tension.
Measure the deflection of the indicated section, which should be 5 - 6mm in the central part using a force of 50 N perpendicular to the same belt.
Lock the nut (2) and the four adjusting plate fixing screws (1).
