Air-Conditioning Refrigerant - Removal
Read through the safety regulations before you do work on the air conditioning system.
WARNING
• Wear protective glasses and sealed gloves. There is a risk of burn and freeze
injuries.
• If refrigerant touches your skin, put that area of your body in a bath of cold
water to prevent a burn injury.
• If you get coolant in your eyes, flush them fully with water for a minimum of
10 minutes. This prevents eye injury.
• Do not release refrigerant into the atmosphere. If this is done accidentally,
open doors or windows and let air flow free before you do work again.
Refrigerant gas is dangerous to your health.
• Stay away from refrigerant gas that can come from hot HVAC parts. It is
dangerous to your health and can cause damage to your lungs.
• Start to work immediately when you drain the A/C system. There can be an
A/C oil fume leak if you do not start the work in a small period of time.
• Do not smoke and do not go near open flames when you do work with
refrigerants.
• Do not keep refrigerant containers adjacent to heat. The pressure can
increase and cause an explosion.
WARNING
Servicing must only be done by approved personnel for both the vehicle and
the pressure and test equipment.
Refrigerant is dangerous. Refrigerant is pressurized, it boils at room
temperature and is flammable.
All operations must be done in an area with good air flow away from open
flames and high temperature sources.
Open the hood assembly.
WARNING
Do not disconnect one or more connections in the air conditioning system
with refrigerant in the system.
