Electrical Wirings; Condensate Discharge (See Page 28 Figure 4); Coil Rotation (See Page 28 Figure 5) - AERMEC VED Series Installation Manual

ELECTRICAL WIRINGS

The unit must be connected directly to an electrical outlet or to an inde-
pendent circuit.
WARNING: it is compulsory to connect the power cables Phase (L) and
Neutral (N) to the respective terminals, do not to reverse the connec-
tions, 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.
For installations with three-phase power supply, the following precautions
should be considered:
1. In the presence of breakers or thermomagnetic switches 3P + N, the trig-
gering 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 consid-
eration the operating current equal to 170% of the total load absorbed by
the fan coils for each phase.
CHARACTERISTICS OF THE CONNECTION CABLES
Use H05V-K or N07V-K type cables with 300/500V with insulation, piped or
ducted.
Use a cable with a minimum section of 1mm
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 protected from outside agents.
Stranded cables can only be used with crimping terminals. Check the
VED is supplied with connections to terminals 5 - 4 -3.
To make use of the higher speeds (terminals 2 and 1), disconnect the wires
from the terminals of the default speeds and connect them to the terminals
of the desired speed.
The three speeds must always be adjacent.

CONDENSATE DISCHARGE (SEE PAGE 28 FIGURE 4)

The fan coil drip tray has got 2 condensate discharges (on the
right and left hand side).
It is recommended to use the condensate discharge on the water
connections.
Fit the condensate discharge connection supplied with the unit.
Please make sure you seal together with silicone the drip tray
and the connection.
Seal the drain that is not used.
Connect the tray connection to the condensate drainage system,
using a hose fixed to the tray connection. The drain connections
are designed to be connected to flexible hose only of suitable
internal diameter, avoid applying higher loads and do not used

COIL ROTATION (SEE PAGE 28 FIGURE 5)

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;
- WARNING! Consult the coil rotation diagram before rotating the
coil.
It is important that the coil is installed and rotated in the right
direction.
Rotate the coil correctly and secure it with the previously
removed screws; The spaces between the collector and the hole
on the side must be completely sealed and filled with insulating
material.
Reassemble the coil cover and fix it with the screws;

The wiring diagrams are subject to continuous updates, so it is essen-
tial to use those on the machine as your reference.
The control panel may not be fitted on a metal wall unless this is perma-
nently connected to an earthed outlet.
Before installing the control panel, read the instructions carefully and con-
figure the panel if necessary. Some control panels require the combination
with components supplied as accessories, check availability.
WARNING: Make sure the control panel supports the load of the electric
motor, otherwise placed an SIT3 interface accessory between the fan and
the control panel.
WARNING: The units that are equipped with VMF series thermostats must be
combined with an VMF-SIT interface accessory.
When combining to control panels, the relative wiring diagram must be
respected.
If present, connect the valve and sensor to the control board, in the posi-
tions indicated in the wiring diagram. In installations with a 3-way valve,
the minimum water temperature sensor must be relocated from its stand-
ard mounting in the coil assembly to the delivery hose upstream of the
valve.
If the highest speeds of the motor are required, change the connection to
the control board on the electric motor. Follow the wiring diagram.
WARNING: check whether the installation has been carried out cor-
rectly. FOLLOW THE CHECKING PROCEDURES indicated in the control
panel manuals.
Motor control board
for other purposes.
Make sure the discharge that is not used is closed and not
leaking.
The condensate drain network must be properly scaled and the
piping situated in such a way as to keep an adequate slope
along the route (min. 1%).
If condensate is discharged into the sewage system, install a
siphon to prevent the return of unpleasant odours into the
room.
Carry out a functioning and seal test of the condensate drain
system by pouring water into the tray.
- Block the holes left open by the hydraulic connections on the
left side with insulating material.
- Reassemble the condensate drip tray; The tray is designed to
drain the condensate on both sides. The condensate drain con-
nection should ideally be used on the hydraulic connection
side.
Make sure the discharge that is not used is closed and not leak-
ing.
– Pull the electrical connections out of the right side.
- transfer the electrical wirings to the left side through the cable
grommet;
- Move the support plate, the control board, the earthing u-bolt
and any electric devices from the right side to the left side.
- Reassemble the front closure panel;
