SECTION 7 - MAINTENANCE
Adding Compressor Oil
Add the new YORK L oil into the oil separator with
the YORK oil charging pump (P/N 470-10654), and
proceed as follows :
1. Shut down the unit.
If adding oil restores the correct level, the
unit may keep operating.
2. Immerse the suction connection of the oil charg-
ing pump in a clean container of new oil. Connect
the pump discharge connection to the oil charging
valve. Do not tighten the connection at the valve
until after the air is forced out by pumping a few
strokes of the oil pump, which lls the lines with
oil and prevents air from being pumped into the
system as shown in Figure 64 on page 134.
3. Open the oil charging valve and pump oil into the
system until the oil level in the oil separator is
about midway in the upper sight glass, and then,
close the charging valve and disconnect the hand
oil pump as shown in Figure 64 on page 134.
4. As soon as oil charging is complete, close the
power supply to the VSD to energize the com-
pressor oil heater, which will keep the refrigerant
concentration in the oil to a minimum.
5. The compressor oil heater will maintain the oil
temperature below 160°F (71°C).
Oil Filter
A single oil filter, a replaceable 3-micron cartridge,
is provided in each compressor. Use only YORK ap-
proved oil filter elements.
The oil filter element should only be changed if a prob-
lem exists. Always replace the oil filter element and
O-ring together.
