A/C Coupler O-ring: Technician Safety Information
Utility model air conditioning systems contain Refrigerant-12. This is a special mixture which requires special handling procedures to avoid personal
injury.
WARNING: Always wear goggles and wrap a clean cloth around fittings, valves, and connections when performing work that involves opening
the refrigerant system. Always work In a well ventilated area and avoid breathing any refrigerant fumes. Do not weld or steam clean on or
near any vehicle-installed air conditioning lines or components. If Refrigerant-12 should come in contact with any part of the body, flush the
exposed area with water, and immediately seek medical help.
-
All Refrigerant-12 drums are shipped with a heavy metal screw cap. The purpose of the cap is to protect the valve and safety plug from
damage. It is good practice to replace the cap after each use of the drum.
-
If it is necessary to transport or carry any container of Refrigerant-12 in a vehicle, do not carry it in the passenger compartment. See the
manufacturer's guidelines for storage, transportation, and the maximum temperature to which the container can be exposed.
-
If the occasion ever arises to fill a small Refrigerant-12 drum from a large one, never fill the drum completely. Leave space above the liquid
for expansion.
