VENTO Ergo A50/50-1 Pro
The unit technical maintenance consists in the periodic cleaning of the
unit surfaces and cleaning or replacement of the filters.
1. Fan maintenance (once a year).
•
Pull out the decorative front panel (applicable only for the units VENTO
Ergo A50-1 Pro and VENTO Ergo A50-1 S Pro) and clean the grille.
•
Pull the ventilation unit to remove it, fig. 22.
•
Clean the impeller blades, fig. 23. Remove dust with a soft brush, cloth or
a vacuum cleaner. Do not use water, abrasive detergents, solvents, sharp
objects. Clean the impeller blades once in a year.
2. Heat exchanger and filter maintenance (4 times a year).
•
Pull out the air flow rectifier. Pull the cord to remove heat exchanger with
front and back filters. Do not let the heat exchanger to fall down, fig. 24.
Do not let the heat exchanger fall down. Pull out the filter located after
the heat exchanger.
•
Clean the filters as often as required, but at least once in three months.
After 90 days non-stop operation the sound signal reminds of the need
to clean or replace the filter. The signal is repeated every 5 minutes. Turn
the unit off and clean or replace the filters. To clean the filters flush those
with water or use a vacuum cleaner, fig. 25. Install the dry filters inside
the air duct. Contact a local distributor for the filters stated above in the
section “Technical data”.
•
Even regular filter maintenance may not completely prevent the dust in-
gress into the heat exchanger. Clean the heat exchanger with a vacuum
cleaner at least once a year.
After the filters and the heat exchanger are installed into the unit, press and
hold the button
on the remote controller to reset the motor meter. A
long sound signal confirms that the motor meter is reset.
