Preventative Maintenance
IMPORTANT:
The cleaning of the air return filter located in the passage of the bus and
the condenser serpentine located in the vehicle external part must be weekly carried
out by the owner. Failure in carrying out these maintenance activities may be regarded
as neglectfulness resulting in the warranty cancellation.
As a rule, the air duct cleaning must be carried out every three months, such time may
be reduced in accordance with the use of the air conditioner system, the number of
people to be transported as well as how harsh the environmental conditions are. The
owners of the vehicles are entirely responsible for the cleaning process; they will account
for any cost resulting from the bad quality of air offered to their passengers.
