Ultrasonic Aqueous Bath

Service & Repair Manual

NOTE: All tools and fixtures, including the ultrasonic cleaner well, must be kept completely clean of any contaminants. For this reason, a sepa- rate set of clean tools should be used for the reassembly of enriched air equipment, different from those used for normal air equipment.

ACIDIC PRE-CLEANING – Before performing aqueous cleaning, parts must first be cleaned with the acidic cleaning procedure outlined on page 15 to ensure the complete removal of any corrosion or scale. Final drying, however, is not necessary.

NOTE: Use only LFW™ cleaning solution, which contains an additional degreasing agent. White vinegar is not an acceptable cleaning agent for EAN/ Nitrox pre-cleaning.

CAUTION: It is important to carefully read and understand the Material Safety Data Sheet (MSDS) for any cleaning solution before using it, in order to understand the possible hazards associated with its use, and the necessary precautions that must be followed to avoid them.

General Guidelines

▼It is important to select an aqueous cleaning solution that is non-carcino- genic, non-toxic, and biodegradable, so that it can be safely disposed of by emptying it into a sewer system that is connected to a waste treatment facility. It must also be non-damaging to the materials of soft wearing parts, including seats, O-rings, washers, and gaskets. Last, it must be easily rinsed away so that it leaves no residue. Refer to Table 1 on Page 4, which lists the aqueous cleaning solution that Genesis Scuba has currently approved.

▼The aqueous cleaning solution must be diluted only with distilled water, according to the ratio specified by the manufacturer.

▼It is important to pre-heat the aqueous cleaning solution to approximately 130º F.

▼The aqueous cleaning solution can be reused at least once, but will eventually require replacement as more contaminants and particulate matter are held in suspension. Frequently examine the appearance of the previously used solution in a clear beaker, and compare it along- side another beaker containing fresh solution in good lighting (diluted with the same ratio of demineralized water). When the appearance begins to vary between fresh and used, or when contaminants can be visually detected, the solution should be disposed of and replaced with new. Whenever in doubt, dispose of the solution and replace with fresh.
