The Hot Water Shroud should be used whenever diving in water colder than 34 °F (1 °C). The shroud completely
encases the side block, bent tube and demand regulator to provide efficient gas heating. It is designed to be
integrated with a hot water supply to help maintain breathing gas temperature at a level acceptable for use by
the diver. Even with water temperatures at 34 °F (4 °C) or slightly above, the diver can experience discomfort
and severe heat loss through the respiration process. Heating the diver’s gas is especially important in cold
water and/or when breathing mixtures of helium and oxygen. For these reasons, Kirby Morgan recommends
the use of the hot water shroud in waters colder than 34 °F (1 °C).
The P/N 525-100 Hot Water Shroud Kit shown in this manual fits most KM model helmets and BandMasks®,
but DOES NOT FIT the Stainless Steel models (KM 77, 37SS, KM 97, KM Diamond) or the KM 47. For informa-
tion regarding hot water shroud kits for these models, please contact your Kirby Morgan dealer or e-mail
[e-mail].

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 steady flow knob, locknut, and spring.
3) Remove the emergency valve knob, nut, and spring.
4) Screw the regulator adjustment knob in all the way.
5) To install the rubber regulator cover, slide it over the
bent tube assembly and stretch it over the regulator ad-
justment knob.

6) Install the rubber side block cover. Start by inserting
the one way valve through the square hole on the back
side of the cover. All the other holes will then line up
correctly.
7) Slide one of the PVC Flanges over the bent tube and
insert it into the regulator shroud.
8) Slide the corrugated tube over the bent tube. The PVC flange previously installed in the reg shroud mates
with the corrugated tube, with the tube rubber going over the PVC Flange and the reg shroud rubber.
9) Install the second PVC flange in the other end of the
corrugated tube. (¼of the flange should still show).
10) Attach the side block end of the bent tube to the side block assembly. Using the torque wrench and ⁄
attachment, torque the bent tube. See the "Torque Specs" module. If the regulator end of the bent tube was
loosened, torque the jam nut. See "Torque Specs" module.
