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.
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 (2 units) using the supplied tamper-
proof screwdriver.

The casing is fixed to the base by means of inner bolts. Extract the lower part of the
casing, as shown in the image, and lift it slightly to release the anchors.
To avoid scratching the casing, place it on a flat surface with the visible part facing
upward.

Motor
Characteristics
- Type: Universal brush motor
- Power: 250 W
- Speed of rotation: 5,500 rpm
- Class F
- Incorporates a safety thermal limiter
Maintenance
The corrective maintenance of the motor consists of replacing the brushes.
The brushes have a theoretical useful life of 3,000 hours and must be replaced when
their length is shorter than 5 mm.
Replacement of the brushes
Press the clip that holds the brush.

Move the clip to one side to release the brush.
Remove the brush from its location and replace it. Carry out the same
procedure for the second motor brush.
Assemble by following the previous steps in reverse order.

Replacement of the motor
For greater safety, we recommend you disconnect the three heating element cables that
go to the three-way terminal block of the electronic circuit board.
Use pliers to carefully extract the two circlips that secure the heating element.

Rotate the heating element a quarter turn clockwise, until it is released from its anchors.
Carefully remove the heating element from its position.

Disconnect the cables of the motor that go to the two-way terminal block located in the
electronic circuit board.
Carefully remove the electronic circuit board from the guide located at the base by bending
the clips that are located in the volute.

Release the screw attaching the volute to the base.
Remove the heating element ring located to the left of the fan.

Loosen the set screw that secures the fan to the drive shaft, inserting an Allen key through
the hole in one of the fan blades. Remove the fan.
Release the two lateral springs that fasten the motor.

Remove the motor from its position and replace it. Fit it by following the
previous steps in reverse order.
Heating element
Characteristics
- Band type coiled cable double heating element in Cr, Al and Fe.
- On MICA body.
- Incorporates a thermal limiter.
- Automatic disconnection 0.5 seconds before the motor stops.
Maintenance
As preventive maintenance, we recommend using a soft brush to remove dust and dirt on
an annual or bi-annual basis, depending on the dryer’s operating cycles.

Replacement of the heating element
Disconnect the three heating element cables that go to the three-way terminal block of
the electronic circuit board.
Use pliers to carefully extract the two circlips that secure the heating element.

Rotate the heating element a quarter turn clockwise, until it is released from its anchors.
Remove the heating element from its housing in the volute and replace it. Fit it by following
the previous steps in reverse order.

Electronic Circuit Board
Characteristics
- Electronic sensor, with infrared beam.
- Detection distance from 5 to 20 cm adjustable by means of a potentiometer.
- Polycarbonate viewer.
- Selective detection of fixed targets.
- Automatic disconnection system after 120 seconds of continued use.
- Automatic temperature regulation at the air outlet according to the room
temperature.
Maintenance
As preventive maintenance, we recommend using a soft brush to remove dust and dirt on
an annual or bi-annual basis, depending on the dryer’s operating cycles.
It is also recommended to clean the LEDs regularly using a cloth dampened with alcohol
to ensure the signal is emitted and received properly.
Replacement of the electronic circuit board
Disconnect the three heating element cables that go to the three-way terminal block of the
electronic circuit board.

Disconnect the cables of the motor that go to the two-way terminal block located in
the electronic circuit board.
Carefully remove the electronic circuit board from the guide in the base by
bending the clips located in the volute.

Disconnect the electronic circuit board from the terminal block in the junction box of the
base and replace it.
Fit it by following the previous steps in reverse order.
Insert the circuit board into the guide at an angle of 45º for it then to be positioned
perpendicular to the base.
Replacement of the LED cables
Remove the LED cables from their connection to the electronic circuit board.

Release the LED cables from the guide that secures them to the volute.
Remove the LEDs from their housing.

Setting the detection distance
The detection distance can be set between 5 and 20 cm, by means of the
potentiometer located in the chassis of the LED cables.
