Temperature Limitations: Use at water temperatures below 33 Degrees F (1 Degrees C) requires use of Hot Water Shroud (PN 525-100) and hot water.


The Kirby Morgan Hot Water Shroud (Part ,525-100) in conjunction with hot water to the commercial diver should be used whenever commercial diving operations are conducted using HEO2 at water temperatures less than 60 Degrees F (15.56 Degrees C) for the comfort of the commercial diver. Kirby Morgan DSI further recommends that the hot water shroud be used in conjunction with hot water to the commercial diver whenever commercial diving operations are conducted using air or mixed gas in waters colder than 36 Degree F (2.22 Degrees 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 Degrees F (0 Degrees 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 Degrees F (2.22 Degrees C) or warmer but the topside air temperature is below freezing (32 Degrees F (0 Degrees 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. Only commercial diving equipment certified and tested according to EN 250E DIN 58 642 may be used with the The Kirby Morgan Commercial Diving Helmet 57 when conducting commercial diving operations in European EC compliant countries. 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. Regardless of the system used the umbilical is the commercial diver&rsquos life line and should always be of excellent quality and maintained carefully.
