11 INSTALLATION REqUIREMENTS
The fan coils should be installed in a position where the room can be cooled
or heated evenly, on walls or ceilings able to withstand their weight.
It is advisable to install any accessories on the standard unit prior to
positioning the latter.
For installation and use of accessories, please refer to the relative technical
sheets.
To guarantee the proper functioning of the unit and access for routine and
extraordinary maintenance purposes, it is necessary to comply with the
minimum installation clearance requirements (see "overall dimensions"
section).
In case of recess mounted units an access panel should be provided.
In order to avoid hot air stratification in rooms heated with ceiling mounted
fan coils, it is recommended:
- not to exceed the "H" installation heights referred to the maximum operating
speed as shown on the diagram;
- supply the units with moderately hot water (water inlet 50/60°C);
- provide the air intake from the lower part of the room, if possible.
Install any remote control panel in an easily accessible position allowing the
user to set the functions while ensuring an accurate reading of the ambient
temperature, if provided . You should avoid:
- positions directly exposed to sunlight;
- positions exposed to direct currents of warm or cold air;
- placing obstacles that impede an accurate temperature reading.
During wintertime periods of quiescence, drain water from the system, to
prevent ice from forming. If anti-freeze solutions are used, check for their
freezing point using the table below.

12 MAINTENANCE
ESTRO BLDC type fan coils do not have particular maintenance requirements:
it is sufficient to periodically clean the air filter.
The motor requires no maintenance since it has self-lubricating bearings.
It is recommended to replace the air filter once a year, using an original
replacement filter; the fan coil unit model is specified on the identification
plate on the inside of the side panel.
Always consult the "Installation, use and maintenance manual" provided with
the unit when undertaking maintenance and cleaning.
