Atlas & Yukon Second Stage

1.Place the parts inside a clean dip basket and lower the basket into the tank of a separate ultrasonic cleaner which contains an approved aqueous cleaning solution. (Refer to Table 1 for an approved and recommended solution, and follow the manufacturer’s instructions for dilution rates and recommended working temperatures.) Be certain to isolate more delicate parts, in order to prevent metal on metal contact with other parts or the dip basket that can cause damage to sealing surfaces.

2.Before removing the parts, it is important to don clean powderless latex gloves in order to prevent any subsequent contamination with skin oils. Avoid touching the external surface of the gloves with bare fingers in the process of donning. Without this barrier present, parts will become contaminated with skin oil.

NOTE: It is important to avoid handling clean parts with bare hands while performing the rinsing, inspection, and reassembly procedures. Doing so will re-contaminate the parts with skin oil, and require them to be cleaned again prior to reassembly.

3.With a small, nylon brush and lint-free swabs, scrub all surfaces of each part, and allow to soak for an additional 5-10 minutes before removing from the ultrasonic cleaner. Certain parts with complex features may require more attention - especially those which contain closed recesses and chambers. It is important to ensure that these are thoroughly flushed with solution, and that contaminant residue is not trapped inside.

Demineralized or Distilled Water Rinse:

NOTE: Tap water drawn from the faucet often contains high levels of minerals, and is considered unsuitable for use with aqueous cleaning, either as a diluent or final rinse. Inexpensive filtration systems may be used which easily filter out most minerals, rendering the water “deminer- alized.” For high volume operations, this is a less expensive alternative to bottled distilled water.

1.When immersion in the aqueous cleaner has been completed, it is extremely important to transfer all parts into a clean container filled with fresh distilled or demineralized water that is heated to approxi- mately 140˚ F, to facilitate faster drying. Rinse each part thoroughly with mild agitation to ensure thorough rinsing and the complete re- moval of cleaning solution. Parts with more complex features will re- quire additional attention to ensure complete rinsing of threads, crev- ices, and recesses.

2.Dry immediately afterward, using only low pressure (50 psi), hydrocar- bon-free gas (Nitrogen or EAN).

3.When drying is completed, set the parts aside on a clean, lint-free surface covered with butcher paper or cellophane.
