Appendix A2
Maintenance and Inspection Procedures
The following section describes the maintenance and
inspection procedures that are used to complete the
Annual, Monthly and Daily Checklists, to ensure
optimum reliability and performance. These procedures are additionally utilized in conjunction with
the daily pre and post dive maintenance checklists.
The following service intervals are the minimum
recommended for helmets being used under good
conditions. Helmets used in harsh conditions, i.e.,
contaminated water, welding / burning operations,
or jetting may require more frequent servicing.
The intention of the maintenance and overhaul program is to help maintain all helmet components in
good working order in accordance with KMDSI factory specifications. It will also help to identify worn
or damaged parts and components before they affect performance and reliability. Whenever the serviceability of a component or part is in question, or
doubt exists, replace it. All helmet components and
parts have a service life and will eventually require
replacement.
NOTE: The side block does not need to be removed
from the helmet annually, providing, after removal of
side block components, there is no corrosion and verdigris. Kirby Morgan recommends that every three
years the side block assembly be physically removed
from the helmet per Section 7.3. Clean and inspect
the stud and securing screw, replace if bent, stripped,
or any damage is detected.
NOTE: The pipe thread fittings used on the umbilical adapter and the emergency gas valve are the only
fittings that require sealing with Teflon® tape. Do not
use liquid sealant. When installing Teflon® tape on
pipe threads, apply the tape starting one thread back
from the end of the fitting. Apply the tape in a clockwise direction under tension. 1-1½ wraps is all that is
needed. The use of more than 1½ wraps could cause
excess Teflon® tape to travel into the breathing system. Do not overtighten when installing.
Chapters 6, 7 and 8 of this maintenance manual gives
guidance on all routine and corrective maintenance
and repairs. Disassembly and reassembly of components is explained in a step-by-step manner that may
not necessarily call out that all O-rings and normal
consumable items will be replaced. The manual is
written in this way so that if an assembly, compo162
nent, or part is being inspected or disturbed between
normal intervals it is acceptable to reuse O-rings and
components providing they pass a visual inspection.
When conducting annual or scheduled overhauls all
O-rings should be replaced. The side block should be
removed from the helmet at least every three years
(or 400 operating hours) so that the stud and securing screw can be inspected. All O-rings should be
lightly lubricated with the applicable lubricant.
Lubrication / Cleanliness: 
Helmets intended for use with breathing gas mixtures in excess of 50% oxygen by volume, should be
cleaned for oxygen service. They must only be lubricated with oxygen compatible lubricants such as
Christo-Lube® or Krytox®. All air supply systems
must be filtered and must meet the requirements
of grade D quality air or better. Helmet breathing
gas systems/gas train components used for air diving should only be lubricated with silicone lubricant Dow Corning® 111 or equivalent. KMDSI uses
Christo-Lube® at the factory for lubrication of all gas
train components requiring lubrication, and highly
recommends its use.
Before 1999, Kirby Morgan Dive Systems, Inc., used
Danger and Warning Notices in the helmet and mask
owner’s manual limiting the breathing gas percentage to less than 23.5 percent oxygen. This was due
primarily to cleaning issues in regards to possible fire
hazards and was in compliance with the recommendations of the Association of Standard Test Methods
(ASTM), National Fire Protection Agency (NFPA),
and the Compressed Gas Association (CGA) as well
as other industry standards.
During the 1990’s, open circuit scuba use of enriched-air (Nitrox) by technical and recreational
divers became very popular, and as use increased,
so did the number of combustion incidents during
the mixing and handling of the breathing mixtures.
These combustion incidents brought attention to the
dangers and inherent risks associated with oxygen
and oxygen enriched gas mixtures.
Kirby Morgan cannot dictate or override regulations
or recommendations set forth by industry standards
or governing bodies pertaining to enriched gas use.
However, it is the opinion of Kirby Morgan that
breathing gas mixtures up to 50% oxygen by volume
© ⅯⅯⅩⅡ Kirby Morgan Dive Systems, Inc. All rights reserved. Document # 120613005
SuperLite® 17B
should not pose a significant increased risk of fire
or combustion in Kirby Morgan helmets and masks
low-pressure components and does not warrant the
need for the stringent specialized oxygen clean postsampling and particulate analysis normally accomplished for components used in high pressure oxygen
valves, regulators, and piping systems. The decision
for using 50% has been primarily based on a long
history of operational field use.
As long as Kirby Morgan helmets and masks are
cleaned and maintained in accordance with the
maintenance manual, the equipment should not pose
a significant increased risk of a fire or ignition originating in the helmet or mask low-pressure (<250
p.s.i.g. /<17.2 bar or less) components when used
with enriched gases of up to 50% oxygen. However,
CAUTION should be exercised any time enriched
gases are handled or used.
In general, helmets and masks used primarily for
mixed gas use are subject to far less oil and particulate contamination than those used for air diving.
For this reason, helmets and masks commonly used
with both air and enriched breathing gases should
be cleaned and maintained with greater care and
vigilance. It is important that all internal gas-transporting components, i.e., side block, bent tube, and
demand regulator assemblies remain clean and free
of hydrocarbons, dirt, and particulates. Whenever
the equipment is depressurized, all exposed ports or
fittings should be plugged or capped to help maintain
foreign material exclusion.
Gas train components should be cleaned according
to the procedures outlined in the operations manual
at least annually and/or whenever contamination is
suspected or found. Helmet interior and exterior surfaces should be cleaned at least daily at the completion of daily diving operations. Helmets and masks
used in waters contaminated with oils and other
petroleum or chemical contaminants may require
cleaning after each dive.
Helmet and mask components requiring lubrication should be lubricated sparingly with lubricants
approved for oxygen use such as Christo-Lube®,
Krytox®, or Flourolube. KMDSI highly recommends
using Christo-Lube®, and uses Christo-Lube® during
the assembly of all KMDSI gas train components.
Regardless of the approved lubricant used, never mix
WARNING
Do not use lubricants of any kind on the
diaphragm or exhaust valves. Use of lubricants can attract and hold debris that
could interfere with the proper operation
of the regulator.
different kinds of lubricants. Persons mixing handling and working with breathing gases should be
properly trained in all aspects of safe gas handling.
NOTE: Refer to Chapter 7 for removal and disassembly
/ reassembly procedures.
NOTE: The helmet weights do not need to be removed
from the helmet unless fiberglass damage is present or
suspected.
NOTE: During annual overhauls, all O-rings and soft
goods, i.e., valve seats and washers should be replaced.
KMDSI offers kits that have all the necessary parts.
NOTE: The neck dam rubber need not be replaced if
the inspection reveals no damage or significant wear and
the rubber components are not dried out.
NOTE: The oral nasal mask and oral nasal valve requires replacement, only if inspection reveals damage,
distortion, or signs of damage. 
NOTE: All threaded fasteners and parts require careful cleaning and inspection as well as the mating parts.
Replace any and all threaded parts or components that
show signs of wear or damage.
KMDSI highly recommends a certified KMDSI repair
technician make all repairs and that only genuine KMDSI
repair and replacement parts be used. Owners of KMDSI
products that elect to do their own repairs and inspections
should only do so if they possess the knowledge and experience. All inspections, maintenance and repairs should
be completed using the appropriate KMDSI Operation and
Maintenance Manual.
Persons performing repairs should retain all replacement
component receipts for additional proof of maintenance
history. Should any questions on procedures, components,
or repairs arise, please telephone Kirby Morgan Dive Systems, Inc., at 1-805-928-7772 or E-mail them at [email protected]

Appendix 3
Supply Pressure Requirements & Tables
Table 1 should be used whenever low pressure
compressors are used or when using surface control
panels that are limited to outlet pressures within the
range of 220 psig or less.
It is important to insure the required outlet pressure from the table can be maintained in a stable
manner at the surface to insure adequate supply at
depth. When used with high pressure consoles that
can regulate pressures greater than 220 psig use
Appendix 3 Table 2 SuperFlow® / SuperFlow® 350
Regulator High Pressure Regulated Source.
Diver Work Rates
The divers work rate, also known as respiratory
minute volume (RMV), is basically how hard the
diver breathes. As the diver’s physical exercise
increases, so does the ventilation rate. Proper training teaches the diver to never push the work rate
beyond normal labored breathing. (This is in the
30-50 RMV range). To put things in perspective,
heavy work for a physically fit person:
Swimming at one knot is about
38 RMV.
Running at 8 miles per hour is about 50 RMV.
Once the diver hits 55 RMV, they are entering the
extreme range. Many fit divers can do 75 RMV
for one to two minutes providing the inhalation
resistive effort of the breathing system is not much
above 1-1.3 J/L. The divers work rate should never
be so heavy that the diver cannot maintain a simple
conversation with topside.
When the work rate gets into the moderately heavy
to heavy range 40-50 RMV the diver needs to slow
down!
can mask CO2 symptoms which can then snowball into even heavier breathing, often resulting in
confusion, panic, and in rare cases muscle spasm,
unconsciousness, sometimes resulting in death.
In some rare cases high ventilation rates has been
suspected as the cause of respiratory barotraumas,
including arterial gas embolism. The possibility of suffering a respiratory over inflation event
during high work rates while underwater could be
even greater for divers that smoke, or have previous known or unknown lung disease or respiratory
damage. The safest course for the diver is to keep
the equipment properly maintained for peak performance and to know and understand the capabilities and limitations of the equipment including all
breathing supply systems they use.
The output capability of the supply system including umbilicals should be known to all that use it
and periodic tests should be done to insure flow
capability.
Use Of Low Pressure Supply Table
The low pressure supply tables were developed to
simplify calculation of supply pressure. In order to
get the required volume to the diver, you need to
have the proper supply pressure. The table starts at
90 psig and increases in 10 psig increments. The
user simply selects the lowest pressure that best represents the low cycling pressure of the compressor
being used. The table basically shows the maximum depth that can be attained while breathing at
RMV’s (breathing rates in liters per minute) listed.
It is strongly recommended that divers plan for a
minimum supply pressure that will allow the diver
to work at no less that 50 - 62.5 RMV.
Working to the point of being excessively winded
should be avoided at all costs!
Working at rates greater than 58 RMV underwater is extreme, and can pose hazards that are not
present when doing extreme rates on the surface.
When underwater, inhalation and exhalation resistive effort increases due to the density of the breathing gas and resistive effort of the equipment. The
increase in resistive effort can cause an increase in
blood level CO2 because the diver cannot ventilate
as freely as when breathing at the surface. When
breathing air at the deeper depths, nitrogen narcosis

*May not be capable of performing at 75 RMV deeper than 165 FSW.
Performance is based on a minimum of 75 RMV to 165 FSW (50 MSW) and 62.5 RMV to 220
FSW (67 MSW) using a 3/8" (9.5 mm) umbilical 600 foot (183 meters) long, made up of two 300
foot (91 meter) sections.
Appendix 4 Standard Kirby Morgan Surface Supply Pressure
Formula - Old Method
Old Pressure Table Calculation:
The old method of determining supply pressure was to multiply the dive depth by .445 PSI and then add the
over-bottom pressure called out in the depth ranges for the depth from the KMDSI operations manual. The old
method was based on a minimum RMV of 62.5. This method can still be used. The old method used the formula
and called out over bottom pressures for depth as follows [(FSW x .445) + PSIG for depth] from the table below.
