General maintenance
Preventive Maintenance - Cleaning
Inspect the units annually or quarterly, depending on the dryer’s operating cycles.
Clean the active parts of the unit, such as: the motor, the heating element, the fan and the
electronic circuit board with a soft brush. In automatic versions, clean the infrared sensor
with a cloth dampened with alcohol.
Maintain the air inlet and outlet free of dust and other obstructions; use a soft flat ended
brush.

Removal of the casing
Consult the safety regulations prior to carrying out any work on the unit.
Release the screws that attach the casing (4 units) with a Phillips-head screwdriver.
Remove the casing from the base.
To avoid scratching the casing, place it on a flat surface with the visible part facing
upward.

Replacement of the motor
Automatic version
Loosen the nut that secures the fan to the drive shaft.

Using an 8 mm hexagonal spanner, separate the base from the rear cover by
applying a slight pressure on the four clips.
Disconnect the two cables from the motor (red and brown) that go to the terminal block of
the electronic circuit board.

With a 7 mm hexagonal spanner loosen the screws located at the crosspiece of the
base.
Remove the motor from its location and replace it. Fit it by following the previous
steps in reverse order.

Using an 8 mm hexagonal spanner, separate the base from the rear cover by applying a
slight pressure on the four clips.

With a 7 mm hexagonal spanner loosen the screws located on the crosspiece of the
base.
Disconnect the two cables from the motor (red and brown) that go to the terminal block of
the timer.

Remove the motor from its position and replace it. Fit it by following the previous
steps in reverse order.

dirt on an annual or bi-annual basis, depending on the dryer’s operating cycles.
Additionally you should regularly clean the LEDs with a cloth dampened with
alcohol.
Replacement of the electronic circuit board
Using an 8 mm hexagonal spanner, separate the base from the rear cover by
applying a slight pressure on the four clips.

Disconnect the electronic circuit board from the grid.
Disconnect the four cables; two from the motor (red and brown) and two from the
heating element (white), from the terminal block of the electronic circuit board.

Remove the electronic circuit board from its housing, carefully freeing it from its four
anchoring points and replace it. Fit it by following the previous steps in reverse order.
Setting the detection distance
Position of the jumper at high sensitivity: detection distance between 20 and 25 cm.

Position of the jumper at low sensitivity: detection distance between 15 and 20 cm.
Notes: Dryers are supplied with the jumper set in the low sensitivity position.
The lighting conditions of the installation site can alter the detection distances.
