Fan Replacement - Frico AR3510 Instrucciones Originales

3. After service, repairs and maintenance
close the service hatch and make sure that
the snap fixings lock properly.
Maintenance
Since fan motors and other components are
maintenance free, no maintenance other than
cleaning is necessary. The level of cleaning
can vary depending on local conditions.
Undertake cleaning at least twice a year. Inlet
and exhaust grilles, impeller and elements can
be vacuum cleaned or wiped using a damp
cloth. Use a brush when vacuuming to prevent
damaging sensitive parts. Avoid the use of
strong alkaline or acidic cleaning agents.
Overheating
The air curtain unit with electric heater is
equipped with an overheat protector. If it is
deployed due to overheating, reset as follows:
1. Disconnect the electricity with the fully
isolated switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and
rectify the fault.
Reset is performed as follows:
1. Locate the red button inside the air curtain
unit. It is visible and accessible by opening
of the service hatch and inlet grille. The
button is on the left side seen from inside
the room looking out. On the 2 metre
variant, two red buttons are installed in the
middle of the unit.
2. Press the red button until a click is heard.
3. Connect the air curtain again.
All motors are equipped with an integral
thermal safety cut-out. This will operate,
stopping the air curtain should the motor
temperature rise too high. The cut-out
will automatically reset when the motor
temperature has returned to within the
motor's operating limits.
Temperature control
Temperature control of SIRe maintains
the exhaust temperature at +40 °C. If the
temperature should exceed anyway there is
an over heating alarm. For more information
see the manual for SIRe.
