6.1.2 Bag filter section check
The soft bag filters are high performance type and require periodical checking, as a marked deterioration may occur
during usage, especially at the point where they are attached to the main frame. This is due to the continuous
deformation, and for the weight of the dust caught.
These filters are not recyclable, and any cleaning may only be carried a few times by turning the filter upside down.
Should it become necessary to substitute the filters, verify the condition of the sealing, and proceed with the substitution.
The bags full of dust must be removed with great care, or to achieve a safer operation, cover the air inlet area. This will
avoid the over-spill of dust inside the apparatus.
6.1.3 Coil check
Check that the Coil exchanger is clean and in a perfect condition so as to guarantee correct performance.
6.1.4 Water humidifier section check
A periodical cleaning of the drip tray is recommended by using steam (high pressure or similar) or specific cleaning
products. Alternatively, replace the evaporation pack, efficient working of which is fundamental to guarantee the air
quality.
The pack must be replaced when limestone build-up is found.
The evaporative pack must be fitted in its correct position, controlling the air direction through the apparatus and the
water flow on the filter.
Always check the cleaning and the efficiency of the outlet and the inlet of the water section.
6.1.5 Power supply check
Control that the power supply voltage falls within the prescribed limits.
6.2 Yearly maintenance
Check that all the electrical equipment, in particular the fixing of the electrical connections.
Check the tightness of all nuts, bolts, flanges and hydraulic connections that the vibrations of the machine may have
loosened.
