Dirty Filter Sensor; Air Filters; Humidifier - Daikin UATYA-BBY1 Installation, Use And Maintenance Manual

4.7.3

Dirty filter sensor

The level of air filter clogging is checked by means of a differential pressure switch that measures the pressure drop
between upstream and downstream of the filter.
The control panel will signal, via an alarm on the display, the need to replace or clean the filter. The machine will
continue to work in any case.
The cut-in value is factory set and can be changed on the installed unit by turning the knob with graduated scale
using a screwdriver.
The fouling of the filter may cause a decrease in the flow rate and therefore of the machine's
performance; restoring the filter as quickly as possible from the time of reporting is recommended.
4.7.4

Air filters

The units are fitted with filters on the air supply side. To replace the filters, open the panel of the unit that shows the
indication for access to the filters.
Cleaning or replacement is essential to ensure good operation of the unit and the correct air flow rate.
4.7.5

Humidifier

The units can be equipped with an immersed electrode humidifier according to the model version. Before use, make
sure all electrical and hydraulic connections have been made.
Should it be necessary to carry out maintenance or replace the humidifier components, first empty the water contained
in the cylinder.
In order to ensure a correct operation and life of the humidifier cylinders, the characteristics of the feed water should
be within the limits provided. The limits are reported in the specific manual.
Do not treat with softeners.
The use of well, industrial water or drawn from cooling circuits, potentially chemically or bacteriologically polluted,
is forbidden. We do not recommend the addition of disinfectants or anticorrosive compounds, as they are potential
irritants.
Any particular characteristics of the water supply, such as very low or very high conductivity, may require specific
humidifier cylinders which differ from the standard, to be agreed upon with the manufacturer.
