This section includes detailed decsriptions of the Kirby Morgan SuperLite 17 as well as important operational specifications. The helmet has been tested and conforms to the performance requirements as set forth in Annex II of Directive 89/686/EEC and as far as applicable, the EN250 (edition Jan 2000) and the E DIN 58 642 (edition Feb 1998). When the helmet is used for air diving in countries that conform to C.E. regulations it may be used to a maximum depth of 164fsw (50 msw). I.A.W. EN250.

- CE Approved:
- The SL 17A/B helmet is CE Approved.
Use at water temperatures below 33o F (1oC) requires use of hot water shroud (P/N 525-100) and hot water.
“The Hot Water Shroud (Part #525-100) in conjunction with hot water to the diver should be used whenever diving operations are conducted using HEO2 at water temperatures less than 60°F (15.56°C) for the comfort of the diver. KMDSI further recommends that the shroud be used in conjunction with hot water to the diver whenever diving operations are conducted using air or mixed gas, in waters colder than 36°F (2.22°C) to reduce the possibility of demand regulator icing.
Usually the greatest danger of demand regulator icing will be encountered on deck when the surrounding air temperature is less than 32°F (0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and the addition of moisture from the divers exhalation coming in contact with the topside air temperature.
If diving where the water temperature is 36°F (2.22°C) or warmer but the topside air temperature is below freezing, (32°F (0°C) icing of the demand regulator is possible. To help eliminate the possibility of freezing on the surface, warm water should be run over the exterior of the demand regulator prior to water entry, if the hot water system is not used.
The umbilical assembly should be composed of good quality diving hose that meets industry standards. Generally, gas hose will be married to the communications wire, pneumofathometer hose, and strength member in a manner that will allow the strength member to receive all the strain. There are also good quality umbilicals available that are assembled at the factory using a twisted method which does not require marrying. Regardless of the system used, the umbilical is the diver’s life line and should always be of excellent quality and maintained carefully.
This system has been used successfully for diving in biologically contaminated environments for many years. To further reduce the possibility of water intrusion regardless of the exhaust system being used, the diver should avoid working in an inverted position.
The Tri-Valve exhaust System has now been replaced by theQuad-Valve System. The unique design of the Quad-Valve keeps exhalation resistance low while maintaining excellent watertight integrity.
