and resolving them before contacting the supplier, as the problem can be easily fixed.

Malfunction

Possible reason 

of malfunctions

Sequencing for correction

Does not work 

or low performance

the filter is clogged

malfunction of the electric heater

reduced airflow

regeneration temperature changes

  air leaks

clean or replace filters

check if the fuse is good

check the air ducts and adjust 

the air flow

check the electric heater

check tightness of seals and panels

Malfunction 

of a breaker or a fuse

the fan is damaged

rotor damaged

the electric heater is damaged

check the fan and its motor

check the rotor drive motor and belt

check the electric heater

The device 

does not starts

no power supply

no control signal

phase short circuit

fuse failure

check the fuse

check external start/stop signal

check the machine and phase 

sequence

check electrical components

Rotor does not rotate

the belt is slipping

the belt is torn or worn

the rotor is stuck

the rotor drive motor is damaged

check belt tension

replace the belt

check center bearing and outer rim

replace the gear motor assembly

Missing
