TURNING THE COIL
TESTING THE FANCOIL
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.
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 galvanised panels (4).
4. Remove the coil fi xing screws (5).
5. Take out the coil (1), being careful not to be cut by the fi ns and not to dama-
ge them.
6. Remove the knockouts on the opposite side of the fan coil (using a screwdri-
ver), to allow the coil connections to pass through.
7. Position the coil, turning it without tipping it upside down, so that the fi ttings
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 (fi xing it to the
side opposite the water fi ttings), the motor and sensor cables (3), if present,
fi xing 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 ea-
sier 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 galvanised panels.
12. Remount the housing (if present).
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) , fi ll 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). The ca-
binet is covered by a protective fi lm: remove it before fi xing the housing
to the appliance.
Remount the housing (if present) , otherwise the customer has the responsi-
bility of concealing the appliance.
CAUTION! Protect the appliance with a cardboard box if building works
are still being carried out (Pic. 18).
