CHANGING THE MOTOR SPEED OF ROTATION
TURNING THE COIL
TESTING THE FANCOIL
The fan coil motor has 6 speed settings, 3 of which are connected in the fac-
tory (red, blue and black wires connected to the motor auto-transformer). To
use other speeds than those wired up in the factory, the red (minimum), blue
(medium) and black (maximum) wires may be connected onto 3 of the 6 num-
bered terminals (1…6), taking into account that the speeds follow a sequence
as shown in Pic. 18.
* CAUTION!
UNDER NO CIRCUNSTANCES SHOULD THE CONNECTIONS TO THE TER-
MINALS L, M, M BE CHANGED!
CAUTION!
The fan may reach the speed of 1,000 rpm. Do not insert objects or hands into
the electric fan. The motor becomes hot during operation; wait for it to cool
before touching it. During the heating mode of operation the exchanger and the
connecting pipes may become very hot (80°C).
Wait for the exchanger to cool before touching it or protect hands with
suitable gloves. The heat exchange water coils are suitable for working up
to ma maximum pressure of 8 bar.
To turn the coil, proceed as follows:
A) Remove the housing (if present).
B) Remove indicate screws in picture:
- 1,2: standard coil screws;
- 3: auxiliary coil screws;
- 4,5: main drain pan screws;
- 6,7: motor screws.
C) Disconnect the terminal block or the
control panel (2), if present, from the side
of the appliance;
D) Take out drain pan (A).
Upon completion of installation, scrupulously check both the water and the elec-
trical connections before switching on the appliance.
Before mounting the housing (if present)
, fill the system, bring it up to pres-
sure and bleed. Make the water circulate and check for leaks.
Check correct operation of the fan coil at the 3 speeds, of the solenoid
valves and of the minimum temperature thermostat (if installed).

E) Take out auxiliary coil (C), if present,
and standard coil (B).
Prestare attenzione a non tagliarsi con
le alette e a non danneggiarle.
F) Remove the knockouts (6) on the oppo-
site side of the fan coil (using a screwdri-
ver), to allow the coil connections to pass
through.
G) Position the coil, turning it of 180°, so that the fittings are in line with the holes
left by the knockouts. Fix the coil using the previously removed screws.
H) Shift the control panel, if present, or the terminal block (fixing it to the side
opposite the water fittings), the motor and sensor cables, if present, fixing them
with their grips. Ensure that the cables pass through the hole in the side of the
appliance, protecting them with the relative grommet. If it proves easier to carry
out this operation by separating the wires from the terminal blocks, mark the
positions of the wires to avoid making mistakes when reconnecting.
I) Reconnect the wires to the relative terminal blocks or control panel, taking
care that they are correctly positioned.
L) Reassemble the components previously removed and follow the steps A, B,
C, D, E, on the contrary.
ATTENTION:
Copper fittings for valve are different between right and left installation.
If hydraulic connections have to be modified on site, it’s necessary to order the
correct installation kit.
