    Abstract: In one embodiment, after a new filter unit (3) is installed in a treatment liquid supply apparatus, there is performed, before a solvent-containing treatment liquid is passed through the filter unit, a step of soaking the filter unit with a solvent for pretreatment and then discharging therefrom the solvent. The solubility of a material, constituting a filter part (31) of the filter unit, to the solvent is greater than the solubility of the material to the treatment liquid. This step makes it possible to remove a component, which may elute from the filter part into the treatment liquid to produce foreign matters (particles), before treatment liquid is passed through the filter unit.
