The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.

Whenever you have the air conditioning
syste m serviced, make sure the service
facility uses a ref rigerant recycling
system. This system captures the
ref rigerant for reuse. Releasing
refrigerant into the atmosphere can
damage the environment.
