Approved Hermetic Compressor Oils

Use the proper type and amount of oil. A proper oil charge contributes materially to successful
compressor operation and long service life.
Tecumseh Products Company has determined the optimum oil charge for each of its compres-
sors, and this amount is specified on the compressor bill of material. This is a mandatory oil
charge based on the premise that the compressor will be installed in a close-coupled system
designed in accordance with good engineering practice.
Some system designs containing unusual evaporators and/or extensive interconnected piping
may required additional oil. However, since excess oil can also damage compressors, care should
be taken not to exceed the oil charge amounts specified. See "Refrigerant Line Sizes" on pages
76-81. If the correct oil charge is in doubt, please obtain assistance from your Tecumseh Technical
Service Representative.
The approved and alternate oils are shown on Table A-3 and A-4.
