Slightly lift the Faston connectors on the input of the filter. Place the tester probes across the
(4)
live and neutral pins on the same connector. The measured voltage should be approximately
220 VAC.
On a 110VAC model, check that the autotransformer properly generates the
220VAC input to the filter. Otherwise check and/or replace the autotransformer.
