ELECTRICAL CONNECTIONS
WARNING: always check that the electricity supply to
the unit has been disconnected before carrying out any
operations.
In the specific case of electrical connections, the following
must be checked:
- Measurement of the isolation resistance on the electrical
system.
- Testing of the continuity of protection conductors.
Electric circuits are connected to mains voltage of 230V;
make sure that all components correspond to this voltage.
CONNECTING CABLES
Use H05V-K or N07V-K cables with insulation 300/500 V
in conduit or raceway. All cables exterior to the fancoil
must be protected in this way.
Only use power cables with a minimum cross section of
1.5mm
2
.
Position cable lengths not protected by the conduit or
raceway in such a way as to ensure that they are not subject
to stress, twisting or external agents.
When making connections, always refer to the wiring dia-
grams supplied with the unit and shown in this document.
To protect fan coils against short circuits, always fit the
power cable to the units with 2A 250V (IG) thermo-
magnetic all-pole switches with a minimum contact gap of
3 mm.
Each control panel controls a single fancoil.
WARNING: probes have double insulation due to the
presence of 230V AC.
COIL ROTATION
Coils may have to be reversed for match the layout of water
connections. To do so, first remove the body, then, in the case
of Omnia HL C / CM fan coils, also remove the room tem-
perature sensor from its housing. Then proceed as follows:
- disconnect wires from the terminal block;
- remove the probe from the coil (Omnia HL C / CM);
- Remove the drip tray fixing screws and remove the tray.
- Remove the coil fixing screws and remove the coil.
- Remove the push-out covers from the right hand side.
- Turn the coil around and re-fit it using the fixing screws
removed previously.
- Re-fit the drip tray using the screws removed previously.
All drip trays are designed for condensate draining from
either side.
- Move the polythene condensate drain plug to the left hand side.
- Fit the plastic plugs provided in the water ports on the left
hand side from which the water connections were remo-
ved previously.
- Move the terminal board and the earthing point to the left
hand side.
- Pull out the electric motor cable from the right hand side.
- Remove the rectangular push-out cover from the left hand
side panel.
- Recover the cable gland and fit it in the left hand side and
close the hole in the right hand side with adhesive tape.
- Move the electric motor cable to the left hand side, threa-
ding it through the cable gland and arranging it so that it
easily reaches the connector on the side panel.
- Move the control panel from the right to the left of the coil
head, and use the plastic cover you removed to close the
hole.
- Fit the adhesive cable clamps provided to the fan coil
head, arranging them to keep the cable close to the inner
surface of the head.
- Unwind the switch cable for the length necessary to reach
the terminal board on the left hand panel.
- Press the switch cable into the cable clamps.
- Reconnect the control panel electrical connections to the
terminal board.
PACKAGING
The fancoils are delivered in standard packing comprising
protective shells and cardboard.
INSTALLATION
WARNING: check that the power supply is disconnec-
ted before performing operations on the unit.
WARNING : before carrying out any work, put the proper
individual protection devices on.
WARNING: wiring connections installation of the fancoil
and relevant accessories should be performed by a techni-
cian 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.
Install the fancoil in a position that will facilitate routine (fil-
ter cleaning) and special maintenance, and easy access to
the air breather valve on the side of the unit (connections
side).
Note that certain operating conditions could lead to the for-
mation of condensate on the unit housing with subsequent
dripping, or faults to the water circuit or condensate draina-
ge could cause liquids to overflow. For these reasons, avoid
installing the unit on surfaces damageable by moisture.
Make sure that the unit is installed in a site where the
ambient temperature is inside the minimum and maximum
limits 0 - 45°C (<85% R.H.).
To install the unit, proceed as follows:
- Slacken the screws and remove the housing.
- When floor mounting fan coils with skirts, always refer to
the skirt installation instructions and the chapter on
"Dimensions".
- Use expansion plugs (not supplied) when mounting the
unit on the wall.
- Make water connections. To make the air vent from the
coil easier, you are recommended to connect the outlet
water pipe with the connection positioned on the top,
the possible inversion will not affect the proper unit ope-
ration.
The position and diameter of water connectors are given
in the dimensional data.
Insulation of water lines is recommended. Install the con-
densate water collection tray (optional accessory) to pre-
vent dripping during cooling operation.
Size and arrange the condensate drain system in such a
way as to ensure a gradient of at least 1%. If drainage is
emptied into the sewerage system, fit a siphon to prevent
the return of unpleasant odours into the room.
Test the seal of water and condensate drainage connec-
tions.
- Fit accessories (as applicable).
- (OMNIA HL C) To modify electronic thermostat settings,
adjust the dipswitches inside the panel (see section
"DIPSWITCH CONFIGURATION").
- Make all wiring connections as shown in wiring diagrams
and the section "ELECTRICAL CONNECTIONS". Connect
the control panel to the connector on the inside of the
fancoil, then earth the unit.
- Check that the air filter is correctly fitted.
- (OMNIA HL) Check the correct the fancoil operation.
- (OMNIA HL C) Run an Autotest to check that the fancoil
operates correctly.
