5.3. Fan motor assembly

From time to time, check that the turbines and the motor are clean. If necessary,
clean them using a vacuum cleaner, taking care to ensure they are not damaged.
The electric motor's bearings are lubricated for life and do not require specific
maintenance.
● Removing the fan motor assembly:
- Open the electrics box
- Disconnect the wires which form the fan motor assembly bundle.
- Follow the same procedure as for disassembling the main pan (Fig. 18) (see
section 5.2 Condensate drain pans)
- Use a screwdriver to undo the screw securing the turbine and its foolproofing
device (Fig. 19), and remove the turbine
- Remove the grommet cap (Fig. 20, a)
- Pull the fan motor assembly bundle towards the interior of the box
- Undo the 3 motor retaining screws and remove the motor (Fig. 20, b).
To refit, perform the operation in reverse order.

5.4. Heat exchange coil

A clean coil is crucial to the efficiency of the unit. If necessary, clean the coil with a
vacuum cleaner.
If the coil must be disassembled on account of a leak:
Disconnect the electrical supply to the unit before carrying out any work.
● Removing the coil:
- Insulate the unit hydraulically from the network and drain the coil.
- Disconnect the coil inlets and outlets
- Next, follow the same procedure as for disassembling the main pan (Fig. 18) and
the fan motor assembly (Fig. 20) (see sections 5.2 Condensate drain pans and
5.3 Fan motor assembly)
- Undo the 2 screws on the coil retaining clamp (Fig. 21, a) and the coil connecting
plate screw (Fig. 21, b).
- Remove the coil.
To refit, perform the operation in reverse order, remembering to bleed the coil before
refilling with water.

5.5. Return/discharge panel

Wipe the walls with a damp, slightly soapy sponge and buff them using a soft,
