CHANGING THE MOTOR SPEED OF ROTATION
The fan coil motor has 6 speed settings, 3 of which are connected in
the factory (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 numbered terminals (1...6), taking into
account that the speeds follow a sequence as shown in Pic. 18.
* CAUTION!
UNDER NO CIRCUMSTANCES SHOULD THE CONNECTIONS TO
THE TERMINALS L, M, M BE CHANGED!
TESTING THE FANCOIL
Upon completion of installation, scrupulously check both the water and the electrical connections before switching on the appliance.
Before mounting the housing (if present), fi ll the system, bring it up to pressure 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).
TURNING THE COIL
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 ex-
change 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).
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 opposite side of the fan coil (using a screwdriver), to allow the coil con-
nections to pass through.
G) Position the coil, turning it of 180°, so that the fi ttings are in line with the holes left by the knockouts.
Fix the coil using the previously removed screws.
