LOW PRESSURE HOSE ASSEMBLIES

1.Ultrasonically clean both hose fittings by dipping only the hose ends in the LFWacid bath, and rinse thoroughly in distilled water.

2.Inspect each fitting to ensure that all scale and corrosion is removed, and re-clean if necessary, using a small nylon brush.

3.Run aqueous cleaning solution through the hose in both directions, checking to ensure that no foreign matter or loose material exits the hose when it is drained. If evidence of internal decay is visible, dis- card the hose and replace with new.

4.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. If contamination of a glove does occur, it can be cleaned with isopropyl alcohol.

5.Ultrasonically clean both fittings inside and out with aqueous cleaning solution, using a soft nylon brush and lint-free swabs to clean all sur- faces, including threads, crevices, and recesses.

6.Thoroughly rinse the hose inside and out with heated, demineralized water, to completely remove all traces of aqueous cleaning solution.

7.Direct hydrocarbon-free gas through the hose until it is completely dry inside and out.

8.Inspect the hose according to the inspection procedure outlined in these instructions.

9.Set the hose aside on clean surface, and wrap both fittings with cello- phane until it is ready for reassembly onto first and second stages.

LUBRICATION & DRESSING:

Perhaps the most critical component of any equipment used with oxygen enriched air is the lubricant grease. Regardless of the application, Genesis Scuba recommends Christo-Lube®MCG-111 (PN MS150) to be used exclusively for the lubrication and dressing of all O-rings and other internal parts. Christo-Lube®provides superior lubrication and protection to that of silicone grease, especially in high pressure (DIN) systems greater than 3,000 psi, and extreme temperature conditions.

CAUTION: Do not attempt to use silicone grease on any component, regardless of grade or manufacturer. Silicone grease is not suitable for use with oxygen enriched air, and will contaminate the entire system, rendering it non-compatible with EAN/ Nitrox.

Wear clean, powderless latex gloves at all times while handling new O-rings and other parts, to avoid contaminating the parts with skin oil.

Dress all O-rings with a visible film of Christo-Lube, but avoid applying excessive amounts, as this may attract particulate matter that can cause accelerated wear or damage to the O-ring.
