This product uses R134a refrigerant. This refrigerant requires synthetic Ester Oil in the compressor. This cooling
system does not tolerate contamination from any of the following:
Other Refrigerants
Moisture
Petroleum-based Lubricants
Silicone Lubricants
Cleaning Compounds
Rust Inhibitors
Leak Detection Dyes
Any Other Type of Additive
As a result the following precautions should be observed
Use equipment dedicated to R134a sealed system only.
Do not leave a replacement compressor open to the atmosphere for more than 10 minutes.
Always replace the filter-drier when performing any repairs on the sealed system.
If the rubber plugs on the service replacement compressor appear to have been tampered with or
removed, DO NOT USE THE COMPRESSOR. Get another one.
The filter-drier MUST be cut from the sealed system. Never un-braze the filter-drier from system
tubing. Applying heat will drive moisture back into the sealed system.
