Operation Instruction for the user and the qualified installer
16
Clean the filter as often as it gets dirty,
but at least 3-4 times a year.
Once a 90 day period of operation
expires, the ventilator generates a
sound signal as a reminder to replace
or clean the filter. The signal is
repeated every 5 minutes until the
filter maintenance has been
completed! Clean the filters, let them
get dry and install the dry filters inside
the air duct Vacuum cleaning is
allowed.
The filter rated service life is 3 years.
Contact the Seller for spare filters.
Even regular technical maintenance
may not completely prevent dirt
accumulation on the regenerator
assemblies.
Subject the exchanger to regular
cleaning to ensure high heat
exchange efficiency.
Clean the exchanger with a vacuum
cleaner at least once in a year.
To reset the operating time meter
indication, install the filters and the
regenerator into the ventilator and
then press and hold the button for
10 sec until a long sound signal.
