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 exchange water coils are suitable for working up to
a maximum pressure of 8 bar.
To turn the coil, proceed as follows:

1. Remove the housing (if present).
2. Disconnect the terminal block or the control panel (2), if present, from the side of the appliance.
3. Remove the condensate collecting tray in horizontal models or the galvanised panels in vertical models (4).
4. Remove the coil fixing screws (5).
5. Take out the coil (1), being careful not to be cut by the fins and not to damage them.
6. Remove the knockouts (6) on the opposite side of the fan coil (using a screwdriver), to allow the coil connections
to pass through.
7. Position the coil, turning it without tipping it upside down, so that the fittings are in line with the holes left by the
knockouts.
8. Fix the coil using the previously removed screws (5).
9. Shift the control panel (2), if present, or the terminal block (fixing it to the side opposite the water fittings), the motor
and sensor cables (3), 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.
10. Reconnect the wires to the relative terminal blocks or control panel (2), taking care that they are correctly positioned.
11. Replace the condensate collecting tray (4) in horizontal models or the galvanised panels in vertical models.
12. Remount the housing (if present).
