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

UNIT 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 plants, and who is able to check the
plants for the purposes of safety and correct operation.
The fancoil 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 ambient temperature limits are respected 0÷113°F (<85%
U.R.).
To install the unit, proceed as follows (See drawings p. 34):
- Remove the air filter . (See Fig.1 page 34)
- Undo the screws and remove the housing . (See Fig.2 page 34)
- In case of wall-mounted FCZ AS - UA 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.

ELECTRICAL CONNECTIONS

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 plants, and who is able to
check the plants for the purposes of safety and correct operation.
CONNECTION CABLES SPECIFICATIONS
Use H05V-K or N07V-K type cables with 300/500 V with 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 twist. They must be protected from weather conditions.
Stranded wires can only be used with terminating sleeves. Make

ROTATING THE COIL

FCZ AS
If for reasons of water connections, you were to turn the battery, after
removing the cover or the front cover panel, proceed as follows (see
drawings Fig. 7 section "Drawings"):
- Remove the control panel to the right side and remove it by
disconnecting the electrical connections;
- Remove the battery cover (a) by unscrewing the screws;
- Remove the screws that secure the battery (b) and then pull it out;
- Remove the knockouts (d) the right side;
- Rotate the coil and secure it with the screws previously removed;
- Replace the cover (a), securing it with the screws and the plastic caps,
supplied with, in the holes left by the hydraulic connections; all the
trays are arranged for the condensate discharge on both sides. In case
of vertical installation, if you want to make the condensate drain on the

If for reasons of water connections, it was to turn the battery, after
removing the cover or the front cover panel, proceed as follows (see
section "Drawings" Fig. 8):
- Remove the drip tray (a);
- Remove the battery cover (B) by loosening the screws;
- Remove the screws that secure the battery and then pull it out (c);
- Remove the knockouts (d) the right side;
- Rotate the coil (c) and fix it with the screws previously removed;

- Use expansion plugs (not supplied) to secure the unit to the wall.
To install hanging units with the AMPZ brackets.(See Fig.3 page

Make hydraulic connections. For a correct tightening of the hydraulic
fittings during the installation it is necessary to use 10 teflon turns and
a maximum torque of 14 Nm.
Refer to the dimensional data for the position and diameter of the
hydraulic connections.
Insulate water lines adequately or fit the auxiliary condensate
drainage tray (available as an accessory) to prevent dripping during
cooling applications.
The connection between pipe and drip tray must be sealed with
silicone(chapter "drawings - fig.6") .
The condensate drain system should be of an adequate size and
be positioned to favour runoff (min. 1% slope). If condensate is
drained into the sewage system, install a siphon to prevent return of
unpleasant odour into the room.
- Make the electrical wirings as shown in the wiring diagrams. (page 38)
- Refit the air filter.
sure that the strands of the wires are inserted properly.
When making the connections, follow the wiring diagrams supplied
with the equipment and shown in this document.
Wiring diagrams are constantly updated. It is therefore compulsory to
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.
The control panels only comprise electric circuits connected to a power
supply of 230V;
