Maintanance and cleaning
Before starting any maintenance or cleaning operation set the device to standby mode (LEDs in SPEED column turn off)
and wait for the fan to stop.
Filters cleaning
The maintenance time for filters can be set to 90, 180 or 365 days (see specific section in the "programming sequence").
Cleaning /replacement of internal filter (fig. 31): Remove the closing disk (1), remove the filter (2), wash or replace it
and reposition it in its seat with the filter frame; re-insert the closing disk.
Cleaning /replacement of external filter for HRW 40 MONO EVO (fig. 32) model: follow the steps from 1 to 6 and repeat
them in the reverse order once the filter has been cleaned or removed.
Cleaning/ replacement of external filter for HRW 30 MONO EVO (fig. 33) model: follow the steps from 1 to 6 and repeat
them in the reverse order once the filter has been cleaned or removed.
On every model it is mandatory to reset the saturated filter situation by following the procedure described in the section
"parameters programming sequence", before returning to the normal functioning of the device.
N.B. Failure to clean or replace filters causes problems for system efficiency, including:
• Increase in pressure losses in the air circuit and reduction of air flow;
• Consequent decrease in machine yield and worsening of comfort in the environment.
