Cleaning the metal filter
It is recommended to clean the metal filter every three months as follows:
•
Remove the metal filter from the hood and wash it in a solution of water and
neutral liquid detergent, then allow it to soak.
•
Rinse thoroughly with warm water and allow to dry.
•
The metal filter may change colour after several washes. This is not a reason
for a complaint or for replacing the metal filter.
INSTALLING THE NON-RETURN VALVE
Hold the non-return valve with your
hands and align it with the recesses.
Insert the non-return valve and then
turn it until it is secure. The type
of mounting for external air ducts
and the check valve must meet the
requirements of the IEC/EN 60335-1
standard.
