TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS!
Maintenance of the ventilator means regular cleaning of the ventilator surfaces of dust and cleaning or replacement of the filters.
To access the basic assembly units follow the steps:
Remove the front part of the indoor unit, disconnect the connector and remove the cartridge from the air duct by pulling the cord.
Remove the filters from the cartridge.
Clean the filters as they get clogged, but not less than once in three months.
• After expiry of the period set for the hour meter (factory setting 90 days) the filter replacement indicator
appears on the
control panel display.
• Wash the filters and let those dry out completely. Then install the dry filters in the air duct.
• Vacuum cleaning is allowed.
• To reset the filter timer, press and hold the button
for 4-5 seconds.
• The filter rated service life is 3 years.
• For new filters contact the Seller.
Even regular technical maintenance may not completely prevent
dirt accumulation on the regenerator and the fan.
• Clean the regenerator regularly to ensure its high heat recovery
efficiency.
• Vacuum clean the regenerator not less than once a year.
