Choosing the correct oil for your applications
Use the following recommended guidelines for oil selection on R-12, R-22, R-123, R-134a, R-513A,
R-515B, and R-1234ze for YK, CYK (all), YKEP, YKCP, YST, YT, and YD chiller applications. The
guidelines in Table 1 are based on the chiller application and evaporator saturation temperatures.
These operating conditions lead to system operating pressures and temperatures that govern the
oil selection.
To charge the system with new oil, complete the following steps.
1. Fill the oil sump with the quantities in
2. Turn the unit on.
3. Leave the unit on for at least 12 hours. During the 12 hours the oil heaters raise the oil
temperature to the limit specified for correct operation.
