Oil filter change
Note: Routine changing of the oil or
the oil filter is not recommended.
The oil filter is oversized for this
application.
The oil and filter should be replaced
only if analysis reveals that the oil is
contaminated. Oil type and system
capacities are shown in Table 2.
Pressure drop across the oil filter is
shown in Figure 13. Oil filter
pressure drop is the difference
between the two pressure-control
ports.
Refrigerant filter change
If the temperature drop through the
filter is higher than 4K, the filter
should be changed.
