OIL FILTER CLEANING

The oil is filtered to prevent particles from entering the product, or to prevent particles
from being returned to the transformer. Therefore, this filter may need occasional –
cleaning. Figure 9-1 and Figure 9-2 show the oil filter housing and oil filter respectively.
Note: A non-critical error in the product data file, such as error code 18 or 20 can be
suggestive of such action.

Before removing the filter housing, first isolate the product through the
external circuit breaker or external switch and ensure that the oil supply valve
is closed.
To clean the oil filter:
1. If a measurement is in progress, use the TransConnect software to stop the
measurement process and return the product to Standby mode.
2.
3.
Note: Ensure that the wiring around the housing is not damaged in the process.
Care must be taken because there is also a spring behind the filter. Note: A little oil
may leak out.
4. Remove the filter and clean it using a brush and compressed air. Then replace the
filter back into its housing and re-secure the housing.
5. Replace the nut, but use a second wrench to hold the filter housing in place while
the nut is tightened to 65 N.m with a torque wrench.
6. Re-energise the product and it will automatically begin measuring at the next
scheduled time.
