AIR CONDITIONER MAINTENANCE
Air Conditioner components are shown above connected together to illustrate system operation. The components
shown are not to scale. The refrigerant and refrigerant oil are clear in color and not visible in this drawing. The small
arrows inside the components and connecting hoses show the direction of refrigerant flow. The location of each
component is in parenthesis.
Allow only certified personnel to service and maintain the air conditioning system. The Clean Air Act of 1992 states
that anyone who works on air conditioning systems must be certified as proof of their training. Organizations such as
the Mobile Air Conditioning Society (MACS) and the National Institute for Automotive Service Excellence (ASE) are
approved by the Environmental Protection Agency (EPA) as organizations with approved independent testing and
certification programs. Contact your local EPA office for more information.
REFRIGERANT
Always use refrigerant R134a in this equipment.
Air conditioning systems operate under extreme high pressure. The containers
refrigerants are sold in are also under pressure. When released into the air, a
refrigerant boils away and becomes a gas. Its temperature drops INSTANTLY.
Improper handling can cause frostbite and eye damage. If it spills on your skin
or in your eyes, flood the area with cool water and SEEK MEDICAL ATTENTION
IMMEDIATELY. Breathing refrigerant gas can result in respiratory problems,
especially for people with cardiovascular disease.
Always wear safety goggles or a face shield and allow adequate ventilation when
working with refrigerant
