SMCS - 7322-010
Removal Procedure
Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool.
Personal injury can result from contact with refrigerant.
Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.
Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.
Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.
Personal injury or death can result from inhaling refrigerant through a lit cigarette.
Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.
