The oil charge is 45 oz. Because of this large
volume, the oil charge is not critical. The com
pressor is a welded hermetic and there are no pro -
visions for checking or adding oil in the field.
OIL CHARGE 26H5
The compressor is factory charged with two pints
of Carrier PP45EB-302 oil which is a special low

motof oil. Before checking the oil level, operate
the unit for at least 30 minutes to balance the oil
distribution in the system.
