DESCRIPTION
In order to comply with the SAE standard (J639), a pressure relief valve has been incorporated on the air conditioner compressor for the following
models: '88-'91 626/MX-6, '86-'91 RX-7 and '86-'91 B-Series. The pressure relief valve is designed to release refrigerant in order to protect the A/C
system if the high side pressure reaches 450 psi.
As a result of this pressure relief valve, the fuse plug previously used as a safety device is no longer needed and will be eliminated from the receiver/drier
tank. However, the receiver/drier tank with the fuse plug will still be available as a service part for the models listed below because the A/C compressor
used in early production of A/C kits for these models did not have the relief valve.
When replacing the receiver/drier tank during A/C service, check whether the A/C compressor has a pressure relief valve or not.
CAUTION:
The receiver/drier tank without the fuse plug should not be installed on vehicles in which the A/C compressor does not have a pressure relief valve.
