Compressor Retrofit
When replacing another manufacturer's compressor with an Ingersoll Rand
compressor, lubricant compatibility must be investigated. If the lubricant in the system is
listed in the Lubrication Table, lost lubricant may be replaced with that lubricant. If the
lubricant in the system is not listed, it is recommended that the lubricant be replaced with
one on the list or contact Hussmann Global Engineering for further guidance. Consult
the retrofit section of this manual for proper retrofit procedures.
