Check that the unit is perfectly levelled and that the drain pipe is not
obstructed (rubble deposits, etc.).
Check that the water connections (to the heat exchanger and water
drainage) are sealed.
Check that the electrical wiring is perfectly tight.
Be sure that the air purge of the heat exchanger has been carried out.
Reassemble the cabinet.
Turn on the power supply and check the unit running.
7 USE
To use the fan coil unit, refer to the instructions of the control panel, available
as accessory.
The air outlet grids on the cover cabinet can be turned 180° to direct the

The grids and the side doors are snapped onto the cabinet.
Before removing them in order to change their position, cut the power off and
wear protective gloves.

MAINTENANCE

For safety reasons before carrying out any maintenance or cleaning
operation, switch off the unit turning the selection switch to "Stop"
and the power supply switch on position 0 (OFF).
Be careful during any maintenance operation; you could get injured by
some metal parts; use protective work gloves.
The estro fan coils do no require any particular maintenance operation:
only the periodical cleaning of the air filter should be carried out.
It is necessary to carry out a running in period of 100 hours in order to
eliminate all mechanical friction.
The starting up must be carried out at the maximum speed.
For good operation of the estro fan coils follow the instructions below:
- keep the air filter clean;
- do not pour liquids into the unit;
- do not introduce metal parts through the air outlet grid;
- keep the air inlet and outlet free at all times.
Each time the machine is turned on after being idle for a long period, ensure
there is no air in the heat exchanger.
Before using the unit for air conditions, check that:
- condensate drainage is performed correctly:
- the heat exchanger fins are not obstructed by deposits of dirt.
If necessary clean the fins with low pressure compressed air or steam
without damaging them.
9 CLEANING
For safety reasons before carrying out any maintenance or cleaning
operation switch off the unit turning the selection switch to "Stop" and
the power supply switch on 0 (OFF).
Clean the filter at least once a month and in any case before using the unit
(before the heating or the air conditioning season).
For cleaning the air filter proceed as follows (figure 5, page 20):
- remove the air filters that are inside the intake grids located on the front
panel of the cover cabinet (estro FB);
- clean the filter with lukewarm water , or in case of dry dust, with
compressed air (estro FB);
- reach the fan coil through the inspection panel and remove the filter,
turning the locking brackets 90° (estro FBC);
- reassemble the filter after having dried it up (estro FB - estro FBC).
It is recommended to replace the air filter yearly, and to use original spare
parts.; the fan coil model is reported on the nameplate located on the
internal part of the side panel of the unit.
To clean the unit cabinet proceed as follows:
- use a soft cloth;
- do not pour any liquid on the unit, as this could cause electrical shocks
or damage the components inside it;
- do not use any aggressive chemical solvents; do not use very hot water
to clean the air outlet grid.
