Approved Hermetic Compressor Oils - Tecumseh AEA4440YXA Service Data Book

A LOOK AT SERVICE SAFETY
IV. Approved Hermetic
Compressor Oils
Use the proper type and amount of oil. A proper oil
charge contributes materially to successful compres-
sor operation and long service life.
Tecumseh Products Company has determined the
optimum oil charge for each of its compressors, 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 evapora-
tors and/or extensive interconnected piping may
require 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 88-92. If the cor-
rect oil charge is in doubt, please obtain assistance
from your Tecumseh sales engineer.
