A method of manufacturing an electric motor assembly includes inserting the pump motor stator into a vacuum chamber. The pump motor stator comprises a housing having a cavity formed therein and a pump motor stator located within the cavity. The pump motor stator contains an integral cooling tube located radially inward of the stator. The method also includes applying a vacuum to the pump motor stator in the vacuum chamber and flowing a potting material into a gap between the stator and the cooling tube and the stator, the gap extending a first distance longitudinally between the stator and the cooling tube. Pressure is applied to the potting material to push the potting material further into the gap.

A method for restoring a silver oxide-containing hydrophilic coating includes heating the coating to a temperature between about 260&#xb0; C. and about 540&#xb0; C. and maintaining the coating at a temperature between about 260&#xb0; C. and about 540&#xb0; C. in an environment containing oxygen and ozone for less than 24 hours.
