NOTE

The minimum operating temperature recommended for this helmet is 37 degrees F, only in regards to regulator performance. At the time of this writing, no hot water shroud is available for this helmet for heating the diver’s breathing gas.

Without a hot water shroud, the diver may be subject to hypothermia due to cold gas inspiration temperatures. Kirby Morgan makes no physiological recommendations regarding minimum safe operating temperatures for divers using this helmet.

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.

Recommended overbottom (OB)gas supply pressure for best performance at depths are calculated by the formula (fsw x 0.445+14.7) + recommended p.s.i. g.
