4.3 Replacing and cleaning the pump
To replace the pump, proceed as follows:
•
Unscrew the two cover screws using a Phillips screwdriver and remove the cover.
•
Unscrew the plastic wing nut from the float arm. Hold down the stop ring in which the pump is
connected with a fixed wrench (hex 13) and gently pull the pump out.
•
Remove the pawl from the outlet of the removed pump and snap it onto the new one.
•
Repeat the sequence in reverse, taking care to reposition the float so that the water level inside the
tank completely covers the pump.
The pump does not require any particular maintenance. It may be necessary to clean the internal rotating
parts periodically, also depending on the quality of the water used. In this case:
•
Disconnect the pump as described above.
•
Turn the swivel outlet fitting to the unlocked position and remove it.
•
Remove the rotor and impeller and clean them with warm water and a brush. Any limescale deposits
can be removed with vinegar, lemon or specific products. Do not use solvents.
•
Reinstall the fitting and reconnect the pump.
4.4 Replacing the rotating disc
•
Remove the front protection grille, if used, by unscrewing the 3 fixing screws.
•
Remove the central cap of the rotating disc by levering it in the recess with a small slotted screwdriver
(Fig. 4.4.1).
•
Using a screwdriver (hex. 7) unscrew the M4x16 fastening screw of the rotating disc to the motor shaft
and its washer (Fig. 4.4.2).
