Accessories
9.1 Introduction
This section provides the manufacturer’s advice on
how to install KMDSI accessories including the Hot
Water Shroud, Low Pressure Inflator Hoses, and the
Weld Lens and Weld Shield assemblies.
9.2 Hot Water Shroud General
The Hot Water Shroud (Part #525-100) in conjunction
with hot water to the diver should be used whenever
diving operations are conducted using HeO
2
at water
temperatures less than 60°F (15.56°C). The shroud
helps to heat the diver’s breathing gas and helps to
protect the diver from respiratory heat loss.
KMDSI further recommends that the shroud be used
in conjunction with hot water to the diver whenever
diving operations are conducted using air diving, in
waters colder than 37°F (2.22°C) to reduce the pos-
sibility of demand regulator icing.
NOTE: Regulator icing in surface supplied diving is
rare because the umbilical gas supply is at the same
temperature as the water. Usually the greatest dan-
ger of demand regulator icing will be encountered
on deck when the surrounding air temperature is
less than 32°F (0°C).
Regulator freezing is primarily due to the refrigera-
tion effect of breathing air pressure reduction, and
the addition of moisture from the divers exhalation
coming in contact with the topside air temperature.
This happens as the gas expands in the regulator.
When the topside environment air temperature is
colder than 32°F (0°C), icing of the demand regu-
lator while on the surface may be avoided, if the
hot water shroud is not installed, by running warm
water over the exterior of the demand regulator..
9.2.1 Installation of the Hot Water Shroud
Tools Required:
1/4 ” Flat Blade Screwdriver
7/8 ” Open end wrench
7/8 ” Open End Attachment on Torque Wrench
11/16 ” Open End Attachment on Torque Wrench
Small pair of snips (to trim tie wraps)
1) Disconnect the bent tube assembly at the side block
end only. Loosen the jam nut at the regulator. If the
bent tube will not swivel freely, you must loosen the
large nut at the regulator.
2) Remove the free flow knob, locknut and spring.
3) Remove the EGS valve knob, nut, and spring.
4) Remove the one-way valve.
5) Screw the regulator adjustment knob in all the way.
Begin installation of the hot water shroud by loosen-
ing the bent tube at the sideblock.
