Electrical Schematic - Jofel AA17050 Manual De Uso

Trouble shooting electrical schematic
If you discover the following circumstance, please inspection and handiing as following:
Problem
No air blows even if
hands are inserted
Machine works long
time after hands
drawn out, finally
shows E2
No hot wind
Airflow is too low
If the above actions do not work, turn off the power and the ground-fault circuit breaker, and call your dealer
to inspect and repair it if necessary. (Costs are as per agreement with the dealer).

• Put hands all the way in .
• Switch offthe power button, and then remove dirt
or foreign body on sensor after the power light
gone out. When finished, switch on power button.
• Is the ambient temperature higher than 20°C?
• Switch off power, remove front cover. There is a
terminal box inside. Take down the cover of
terminal box. Check the fuse inside box which is
blown or not.
• Put speed button on the high level.

Solution
Check the external power source,
close the power switch
Check motor connecting wires
and the rotor foreign material
Clear workspace foreign material,
restart to work
Turn off the power, re-power After LEDs
are off. Sterilization indicator is still not
lit. Please check the UV Emission plat
Clear workspace foreign material,
restart to work
Check the power supply circuit
Clear the foreign material of the air
inlet and air outlet
Check whether the Fan sensor
connect is loosen
