Chapter 7 Accessories; Introduction; Hot Water Shroud Installation Procedures - Kirby Morgan KMB-18 A/B Operation And Maintenance Manual

7.1 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 assembly.
7.2 HOT WATER SHROUD INSTALLA-
TION PROCEDURES
The KMDSI Hot Water Shroud Kit only fits
the "B" sideblock. The Hot Water Shroud
(KMDSI Part #525-100) should be used
whenever diving in water colder than 35.6 F
(2 degrees C). The KMDSI hot water kit is
designed to be integrated with a hot water
supply to help maintain breathing gas tem-
perature at an acceptable level for the diver.
In addition the hot water reduces the possi-
bility of ice forming in the demand regulator
or gas train components. Even with water
temperatures of 40 F (4 C) the diver can
experience discomfort and severe heat loss
through the respiration process. For this rea-
son, KMDSI recommends installing the hot
water shroud when diving in waters colder
than 40 F (4 C). Water supply to shroud
assembly should be at least 1 gallon (3.7
liters) per minute at a minimum temperature
of 105 F (42C). When diving operations are
conducted during severe cold surface tem-
peratures a hot water shroud should be used
to prevent ice from developing in and on gas
train components while the diver is on the
surface.
