COMPRESSOR REPLACEMENT

CAUTION
NEVER install a new compressor without first checking for possible system
contamination.
To check for contamination, obtain oil sample from old compressor.
• If the oil has burned odor, but no color change or residue — follow
instructions in section "Installing A New Compressor and a New 2 Stage
Filter-Drier on page 55".
• If oil has a burned odor and a sugar or gritty feel as well as showing signs of
contamination (dark color) — follow instructions in next section, To Flush The
System. Remove as much of contamination as possible from system before
installing new compressor and a new two stack filter-drier.
N OTE
It is recommended that system be flushed with dry Nitrogen. However, if refrigerant is
used to flush the system you must look at the serial plate to see what type of refrigerant
is used in the system. This is the only refrigerant that can be used to flush the system
and it must be recovered.
CAUTION
Use extreme care when using Dry Nitrogen to flush systems. Pressure in nitrogen
cylinder could be as high as 2000 psi. Nitrogen cylinder must be equipped with
approved pressure regulator and pressure relief valve. Ensure that your hoses have
adequate ratings for pressure involved and that all of your equipment is in good
condition.
