a normal freezing and defrost cycle.
6. COMPRESSOR
OIL CHARGE 26H3
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
temperature refrigerant duty oil. Do not use ordinary
motof oil. Before checking the oil level, operate
the unit for at least 30 minutes to balance the oil
distribution in the system.
