1. Assemble swirl baffle into nozzle first.
2. To prevent leakage between the nozzle and nozzle retainer,
moisten the corner of a clean, dry, lint-free cloth with a very
®
small amount of Krytox grease P/N73585064. Wipe the
inner surface of the nozzle retainer that comes in contact with
the nozzle. Use care to apply a very thin film to ensure a
proper seal.

nozzle, electrode and water baffle.
