Rotating The Coil - AERMEC FCXI 20 AS Manuel D'utilisation Et D'installation

ELECTRICAL WIRINGS
The unit must be connected directly
to an electrical outlet or to an
independent circuit.
WARNING: it is compulsory to connect
the power cables Phase (L) and Neutral
(N) to the respective terminals, do not
to reverse the connections, and observe
the wiring diagram.
install a device, main switch, or electric
plug so you can fully disconnect the
device from the power supply.
To protect the unit against short
circuits, fit an omnipolar thermal-
magnetic trip 2A 250V (IG) to the
power line with a minimum contact
opening distance of 3mm.
The use of B-type circuit breakers is
recommended.
For installations with three-phase power
supply, the following precautions
Connection with VMF-E18 thermostats
• The VMF-E18 Kit includes the system
with connection cables to the Inverter
Control Module. The cables are wired
with connectors for quick connection.
The installation of the VMF-E18 kit
requires that standard control board and
connection cables to the Inverter Control

ROTATING THE COIL

If the hydraulic connections require the
rotation of the coil, remove the front
closure panel and proceed as follows:
- Remove the condensate drip tray;
- Undo the screws and remove the coil cover;
- 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;
- Reassemble the cover and fix it with
the screws;
- Reassemble the plastic plugs (supplied)
in the holes left free by the water
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 wirings from the
right-hand side, remove the push-out
and move the cable grommet from the
right to the left side;
- Transfer the electrical wirings to the left
side through the cable grommet;
- Move the control board, the earthing
u-bolt and any electric devices to the
left-hand side.

should be considered:
1. In the presence of breakers or
thermomagnetic switches 3P + N,
the triggering current must be at least
170% of the total load absorbed by
the fan coils for each phase.
2. The section of the neutral wire must be
of a dimension taking into consideration
the operating current equal to 170% of
the total load absorbed by the fan coils
for each phase.

CONNECTION CABLES
Use H05V-K or N07V-K type cables
with 300/500V with insulation, piped
or ducted.
All the cables must be piped or ducted
until they are inside the fan coil.
The cables leaving the pipe or raceway
must be so positioned that they are
not pulled or twisted and are anyway
Module (Signal and Supply) are removed
from the fan coil.
• Mount the thermostat housing to the side
of the fan coil units, on the connections
that were of the control board.
• Remove the cover of the thermostat
housing.
• Connect the inverter control module
protected from outside agents.
Stranded cables can only be used with
crimping terminals. Check the wire
strands are well inserted.
The wiring diagrams are subject to
continuous updates, so it is essential
to use those on the machine as your
reference.
The control panel may not be fitted on
a metal wall unless this is permanently
connected to an earthed outlet.

When using remote control panels,
the relative wiring diagram must be
respected. Before installing the control
panel, read the instructions carefully
and configure the panel if necessary.
Connect the valve and sensor to the
control board, in the positions
indicated in the wiring diagram.
VMF-E18 to the thermostat using the
system with connection cables supplied
with the VMF-E18 kit. Check the
connection with the wiring diagram.
• Complete the connections as indicated
in the VMF-E18 thermostat manual.
