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.
e) Fit accessories (as applicable).
f) To modify electronic thermostat settings, adjust the
dipswitches inside the panel (see section "DIPSWITCH
CONFIGURATION").
g) 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.
h) Run an Autotest to check that the fancoil operates correctly.
i) Re-install the casing.
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-magne-
tic all-pole switches with a minimum contact gap of 3 mm.
Each control panel controls a single fancoil.
COIL ROTATION
If coil rotation is required when making water connections,
remove the unit housing then proceed as follows:
- disconnect wires from the terminal block;
- remove the probe from the coil;
- remove the screws securing the drip tray, then lift it out;
- remove the screws securing the coil, then lift it out;
- remove the push-outs on the right side;
- rotate the coil, then secure it in place with the screws pre-
viously removed;
- refit the drip tray then secure it with the screws; fit the pla-
stic plugs (supplied) in the holes left vacant by the water line
connections.
All trays are prearranged for condensate drainage on either
side.
N.B.: Before connecting up the condensate drain, use a tool
to open the diaphragm in the tray (where fitted) on the
water connection side. Seal the unused drain outlet using
the plug provided.
Remove the electrical connections from the right hand side.
Remove the push-out and move the cable sheath from the
right to the left.
- Move the motor cable to the left hand side, passing it
through the protective sheath.
- Move the terminal board and the earthing pin to the left
hand side.
- Restore the motor cable electrical connections.
- Insert the battery probe.
- Remove the switch cards from the right hand element.
- Disconnect the microswitch.
- Remove the reinforcing stay.
- Pass the wire for the microswitch through the opening on
the opposite side.
- Secure the reinforcing stay.
- Fit the thermostat card on the left hand element and fit the
knobs.
- Restore the control panel electrical connections.
