Unit Installation; Electrical Connections; Rotating The Coil - AERMEC FCX ACB Manuel D'utilisation Et D'installation

INSTALLATION
WARNING: check that the power supply is disconnected
before performing operations on the unit.
WARNING: the electrical connections, the installation of the
fan coils and relevant accessories should be performed by a
technician who has the necessary technical and professional
expertise to install, modify, extend and maintain systems, and
who is able to check the systems for the purposes of safety
and correct operation.

UNIT INSTALLATION

To install the unit, proceed as follows:
- Remove the air filter.
- Undo the screws and remove the housing (Fig. 3).
- In case of a wall-mounted FCX-ACB unit, keep a minimum
clearance of 80 mm from the floor. In the case of floor-
mounted units on feet, refer to the instructions supplied with
the accessory.
- Use expansion plugs (not supplied) to secure the unit to the
wall as indicated in Fig. 5.
d) Make the water connections.
Refer to the dimensional data for the position and diameter
of the water connections.
Insulate water lines adequately or fit the auxiliary condensate

ELECTRICAL CONNECTIONS

CONNECTION CABLES SPECIFICATIONS
Use H05V-K or N07V-K type cables with 300/500 V insulation,
piped or ducted.
All the cables must be piped or ducted until they are inside
the fan coil.
The cables coming out of the pipe or duct must not be subject
to stretch or twisting. They must be protected from weather
conditions.
Stranded wires can only be used with terminating sleeves.
Make sure that the strands of the wires are inserted properly.
When making the connections, follow the wiring diagrams

ROTATING THE COIL

If hydraulic connections require the rotation of the coil, remove
the cabinet and proceed as follows:
– disconnect the electrical wirings from the control board,
remove the circuit card from the panel on the right;
– undo the screws and remove the coil case;
– remove the screws securing the coil, then remove the coil;
– remove the push-outs on the right-hand side;
– rotate the coil and secure it with the previously removed screws;
– refit the cover, secure it with the screws, then insert the plastic
plugs supplied in the holes left free by the hydraulic connections;
all the trays can be used to collect condensate on both sides. In
case of vertical installation, to discharge condensate on the right
side, position the drain connection to the right.
– slide out the electrical connection from the right-hand side,
remove the push-out and move the cable guide from the right
to the left side;

The fan coil should be installed in such a way as to facilitate
routine (filter cleaning) and special maintenance operations, as
well as access to the air breather valve on the side of the unit
frame (connector side).
The assembly site must be chosen in such a way that the
maximum and minimum room temperature limits are respected

supplied with the equipment and shown in this document.
Wiring diagrams are constantly updated. Please refer to the
ones supplied with the unit.
To protect the unit against short circuits, fit an omnipolar
magneto-thermal trip 2A 250V (IG) to the power line with a
minimum contact opening distance of 3 mm.
Each control panel can control a single fan coil.
WARNING:The control panels only comprise electric circuits
connected to a power supply of 230V;
– transfer the electrical wirings to the left side through the
cable guide;
– move the terminal block and the U-bolt of the ground to the
left side;
– refit the control card on the left side and reconnect the
electrical wirings;
– for FCX-ACB models, adapt the air filter to the new
configuration by changing the position of the external support
in relation to the filter frame (Fig. 1): press down on the tab (1
Fig. 2) with a screwdriver while moving the external support (2)
until the tab is over the tooth (3).
Then release the tab so that the position between the support
and the filter is as shown in figure 1.
Given that the contact block on the unit is off-centre in
relation to the cabinet housing, the feet must also be
exchanged.
