7. Fault finding
If there is a sudden change in air supply while using the Clean-air system, it is necessary to check the following:
•
That all parts of the air-supplying system are assembled properly.
•
The battery and its connector.
•
Whether the charger is not faulty or malfunctioning (if so, diodes do not work).
•
Filters and their clogging.
•
That there is not a hole in the air hose.
•
Whether the hood seal is not damaged.
Whether the working time after a full recharging of the battery has not decreased (if so, it is necessary to
replace the battery).
Fault –finding guide:
8. Storage
All parts of a Clean-air system must be stored in environment with temperature range 0-40°C and humidi ty
range 20-80% Rh. The storage life is 2 years for the product if stored in original unopened package.
NOTE: Batteries get discharged even if not in use. Therefore in case of a long-term storage it is fully
recommended to charge the NiMH batteries every 12 months.
9. Warranty
There is a 12 month warranty covering production defects , a 6 month warranty for batteries. Warranty begins
from the date of purchase. The claim must be lodged at the dealer’s place. The invoice or receipt must be
declared if claiming the warranty.
The claiming procedure will be successful only on condition that there were no changes made on the blower
unit incl. the battery and charger.
If the damage is caused by not changing a clogged filter in good time or using a filter which has been cleaned by
the customer, the claim will not be proceeded.
