How to repair or replace the oil separator
Open the separator container and replace the separator filter.
Make sure that the new filter is the same size as the old filter. If it is long or short, be sure to adjust the length of the return pipe.
Make sure to use the supplied gasket, because the gasket contains metal conductors, which can prevent static electricity from accumulating in the separator, leading to sparks, and may also lead to explosion of the separator container
