Electrical Wirings; Rotating The Coil - AERMEC Omnia ULI C-Serie Bedienungs- Und Installationsanleitung

d) After completing the hydraulic connections, to help bleed air
from the coil, you are advised to connect the water outlet pipe
to the fitting at the top; any inversion will not jeopardise the
proper functioning of the unit.
The position and diameter of the water connections are shown
in the dimensions.
You are advised to adequately insulate water lines, or fit the
auxiliary condensate drain tray (available as an accessory), to
prevent dripping during the cooling function.
N.B.: Before connecting the condensate discharge, use a tool to
break the tray membrane (if fitted) on the water connections
side, seal the discharge that is not used with the cap supplied
as standard.
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.
Test the seal of the water connections and the condensate dis-
charge.
e) Fit any accessories.
f) To modify the electronic thermostat settings, use the Dip-
Switches through the specific window on the rear of the control
panel (see section "DIP SWITCH CONFIGURATION").
g) Complete the electrical connections with reference to the indi-
cations in the wiring diagrams and the "ELECTRICAL
CONNECTIONS" section, connecting the control panel connector
to the connector on the inside of the fan coil and also complet-
ing the earth connection.
h) Refit the casing.

ELECTRICAL WIRINGS

WARNING: check that the power supply is disconnected before
carrying out any procedures on the unit.
In particular, the electrical wirings require checks relating to:
- Measurement of the electrical system insulation resistance;
- Continuity of the protection wires.
The electrical circuits are connected to the 230V mains voltage; all
the connections and components must therefore be correspond-
ingly insulated for this voltage.
CHARACTERISTICS OF THE CONNECTION CABLES
Use H05V-K or N07V-K type cables with 300/500V with insulation,
piped or ducted.
Use power supply cables with a minimum cross-section of 1 mm
All the cables must be piped or ducted until they are inside the fan
coil.
The cables leaving the pipe or raceway must be positioned in such
a way that there are not traction or twisting stresses and they are
anyway protected from outside agents.

For all the connections, follow the wiring diagrams supplied with
the device and shown in this documentation.
To protect the unit against short circuits, fit an omnipolar ther-
mal-magnetic trip 2A 250V (IG) to the power line with a mini-
mum contact opening distance of 3mm.
We recommend using differential devices suitable for intervening
for currents of different type:
sinusoidal AC and pulsating DC currents suddenly applied
or slowly rising.
sinusoidal AC with frequency up to 1000 hz
Each control panel can control a single fan coil.

ROTATING THE COIL

If hydraulic connections require the rotation of the coil, and pro-
ceed as follows:
– remove the electrical connections from the terminal strip;
– remove the probe from the coil;
– remove the screws fixing the basin and remove it;
– 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 tray, securing it with the screws, insert the plastic plugs
supplied in the holes left free by the hydraulic connections;
all the trays can be used for condensate drainage on both sides.
N.B.: Before connecting the condensate drain remove the cap in
this plastic on the container and use it to plug the drain is not
needed..
Seal the unused drainage hole with the cap supplied as standard.
– slide out the electrical connections from the right-hand side,
remove the push-out and move the cable guide from the right
to the left side;
– move the motor cable on the left side so that it passes
through the fairing;
– move the terminal block and the GND U-bolt to the left side;
– restore the motor cable electrical connections;
– fit the battery probe;
– remove the selector cards from the RH element;
– disconnect the microswitch;
– pass the microswitch cable through the window on the opposite
side;
– fit the thermostat card (selector) on the LH element and fit the
2
. knobs;
– restore the electrical connections on the control panel.
– assembly of this furniture at the machine cover.
