REMOVAL & INSTALLATION
See Figures 1 and 2
In certain areas it may be illegal to service air conditioning components unless you are certified, consult with your local authorities.
Refrigerant lines are secured with either threaded-type fittings or block-type fittings. It is very important to use a back-up wrench on threaded-type fittings to avoid twisting the line. Block-type fittings are simply secured by attaching bolts.
Apply a few drops of clean refrigerant oil to O-rings (always use new ones) and torque their fittings or attaching bolts to proper specifications. Failure to do so can result in broken O-rings, cracked fittings, stripped threads and poor sealing. All of these lead to refrigerant leaks and eventual air conditioning system destruction. It is also important to note that R-12 system components cannot be used in R134a systems. This includes O-rings! The use of improper refrigerant and/or oil will only result in improper cooling and total system destruction.
