1.1 General Information
The Kirby Morgan Switchover Open Circuit Regu-
lator Assembly, P/N 805-050 and our non-mag-
netic version P/N 805-001, is a high performance
scuba regulator designed for professional divers.
The regulator is a modified version of the balanced
455 regulator.
The switchover regulator is designed for use ONLY
with our rebreather pod. It oers a wide range of
adjustment that allows the diver to compensate
for variations in workloads, as well as physical at-
titude and current.
The regulator bias adjustment gives the diver the
ability to fine tune the demand valve at any time
prior to, or during the dive. The bias adjustment
simply increases or decreases spring tension on
the inlet valve assembly. The knob has approxi-
mately 4 ¼ turns from full in to full out position
with a supply pressure of 135–150 PSIG. This bias
device is not intended as a minimum or maximum
device. The bias adjustment should be adjusted by
the diver so that it is at the easiest breathing for
existing conditions.
NOTE
Diving with a bias setting higher than
necessary will result in increased inhalation
eort and could cause the diver to become
exhausted. Diving with the bias adjusted so
the regulator freeflows greatly increases air
usage.

Non-Magnetic Conformity Safety Precautions
This manual is primarily to provide factory trained
repair technicians the information needed to per-
form adjustments and corrective maintenance. We
strongly recommend that service be done by Kir-
by Morgan trained/authorized technicians.
Those who elect to work on their own regulators
should have the proper tools, training and expe-
rience in regulator designs and repair. A sound
technical background associated with diver life
support breathing components is also recom-
mended. All repair parts should be genuine Kirby
Morgan parts and should only be obtained from
authorized Kirby Morgan dealers. All authorized
Kirby Morgan dealers will be found on our website
www.kirbymorgan.com under “Support.”
1.1.1 Non-Magnetic Conformity
In addition to our standard assembly, we manufac-
ture an assembly with non-magnetic designation.
•P/N 805-001 Switchover
Regulator, Non-Magnetic
Refer to the corresponding blowapart drawings at
the end of this module for part numbers specific
to the non mag components used in the above as-
semblies.
NOTE
The label, “Non-Magnetic,” found on
components used in the assemblies above
is based on tests performed at initial
production startup of the products and NOT
based on any ongoing testing.
If products with a non-mag designation are to be
used where the equipment needs a low, or non-
magnetic signature, IT IS THE RESPONSIBILITY
OF THE END USER to apply any specialized test-
ing, to determine if the equipment will pass any
needed, low or non-magnetic requirements.
1.1.1.1 Maintaining and Repairing Non-
Magnetic Designated Assemblies
The use of non-magnetic hand tools is crucial
in keeping complete assemblies and associated
components to a non-magnetic signature. Non
magnetic tools are made of materials that do not
contain iron (non-ferrous metals) and therefore
the risk of a magnetism being created while the
tool is in use is reduced. It is critical to understand
that simply tightening a screw with the incorrect
screwdriver can cause magnetism in the Non-Mag
Switchover Regulator.
1.1.2 Use of Kirby Morgan
Original Replacement Parts
Users of Kirby Morgan life support equipment are
cautioned to always use Kirby Morgan original re-
placement parts. Parts manufactured by third par-
ty companies can cause improper function, lead-
ing to accidents.
Look for the Kirby Morgan logo on Kirby Morgan
products. This is your assurance that you are
getting genuine Kirby Morgan replacement parts.

1.2 Safety Precautions
Routine maintenance is the best way to ensure
long regulator life and optimum performance.
NOTE: If possible, rinse while pressurized and at-
tached to a tank. This will aid in preventing wa-
ter from getting into the inlet valve. Purging the
regulator after rinsing will aid in drying. Purging

Safety Precautions Soft Good Kits
the regulator may cause free flow. This is easily
stopped by slightly blocking the main outlet port.
1. At a minimum, the regulator should be thor-
oughly rinsed with fresh clean water after every
dive. Install blue cap with O-ring onto hose end of
the regulator. Mild liquid dish soap can be used to
remove grime. Avoid harsh cleaners.
2. If possible, the entire regulator should be soaked
in fresh warm water, between 80–120 °F (26–49
°C), for 15 minutes or longer. Soaking in warm wa-
ter will remove salt and mineral deposits more ef-
fectively than a fresh water rinse alone.
3. Allow the regulator to dry completely before
storage. Do not leave the regulator sitting in direct
sunlight. Shake the second stage to help remove
water trapped inside.
BCAUTION
During soaking do not depress the
purge button on the second stage.
Pressing the purge button can al-
low water to enter the inlet valve and
possibly go into the critical balancing
chamber. Water inside the balancing
chamber will lead to improper regu-
lator function, which could result in
personal injury.
4. Turn the second stage regulator adjustment
knob all the way out, away from the second stage
body. This will help lengthen the life of the regula-
tor seat.
5. Ensure the regulator is completely dry before
storing. Store only in a clean, cool, dry place.
BCAUTION
Never store the regulator while still
connected to a SCUBA cylinder. Im-
proper care or storage of underwa-
ter breathing equipment may lead to
equipment malfunction, which could
result in personal injury.
BWARNING
DO NOT use cleaning solvents on any
parts or components of this regulator.
The use of solvents may lead to failure
of the regulator parts and regulator
malfunction, which could cause seri-
ous injury or death.
BCAUTION
NEVER pressurize the rst stage regu-
lator without having a second stage
attached. This can lead to a sudden
burst of high pressure air, causing the
hose(s) to whip about, which could
cause personal injury.
1.2.1 Soft Good Kits
Always refer to M-48 appendices for scheduled
maintenance. These can be located at the back
of the user guides as well as under the support
tab at KMDSI.com. While all individual parts in the
rebreather POD and switchover regulator assem-
blies can be ordered separately, KMDSI has also
created kits to be use used for periodic, annual
and when required service.
Guidelines
O-rings should be lightly lubricated with oxygen
compatible NON SILICONE lubricant ONLY, for
example, Christo-Lube®, Tribolube® or equivalent in
accordance with the operations and maintenance
manual. NEVER USE SILICONE based lubricants.
At a minimum all O-rings found in the switchover
Open Circuit Regulator should be replaced at least
once a year. Components might require replace-
ment more often than yearly if the assembly use
is extreme, or if used in waters containing oil or
chemical contamination. Daily cleaning and in-
spections as well as performing the monthly in-
spection will identify the need more accurately
than simply placing a number of hours between
overhaul. Store spare O-rings, valves and soft
goods in a cool, dark, dry place. Avoid prolonged
exposure to temperatures above 90 °F (32 °C)
and/or exposure to ultra violet rays. Do not lubri-
cate exhaust valves. Lubricating valves can cause
dirt to stick, allowing leakage.

General Information Scheduled Maintenance
BWARNING
If the products to be used where the
equipment needs to have a low, or
non magnetic signature, IT IS THE
RESPONSIBILITY OF THE END USER
to apply any specialized testing, to de-
termine if the equipment will pass any
needed, low or non magnetic require-
ments.
The following is the overhaul kit available for the
Switchover Regulator:
•Part #825-010, Rebreather POD
Regulator Overhaul Kit
1.3 Scheduled Maintenance
Do not assume that a regulator is in good working
order because of infrequent use. Prolonged or im-
proper storage can still result in O-ring deteriora-
tion or internal corrosion that could result in poor
performance.
1) The minimum maintenance suggested for all
regulators is an annual inspection and service.
However, regulators that are used frequently or
under severely harsh environmental conditions
should be serviced more often.
For example, a regulator used for frequent training
purposes may require service every two to three
months or more. Whenever a regulator has been
inactive for longer than three months, it should be
carefully inspected and checked for proper func-
tion prior to use.
1.4 Disassembly Procedures
1.4.1 General Information
Changes in regulator performance will be most
noticeable when the second stage is out of adjust-
ment or needs service. Careful set-up and adjust-
ment of the second stage is essential to maximize

slightly into the regulator body.
This causes lever arm to slide away from interior
wall of regulator body, allowing for its removal.
19. Carefully lift out and remove one leg of the le-
ver arm from its hole in the main tube, while start-
ing to pull the second leg out. This will make re-
moval easier
20. Pull second leg out and free from hole, then
remove entire lever arm from the main tube.

Assemble Switchover Regulator Packing Nut Reassembly
29. Carefully inspect regulator body for damaged
threads, or integrity damage.
NOTE
Earlier versions of the switchover open
circuit regulator used a specially formulated
adhesive to secure the exhaust flange to the
regular body. If using this earlier version, be
aware small surface cracks might appear in
the adhesive material, but have no eect on
the integrity of the bond. Current regulator
bodies (post 2018) are molded as one piece
components
Pay close attention to joints between exhaust and
mounting adapters for damage or large cracks.

NOTE
If the nipple is threaded in too far, it could
possibly damage the inlet valve seat when
the inlet valve is installed.
4. Lightly lubricate and install O-ring onto the
main tube end.
1.5.3 Main Tube Reassembly – Read
this entire procedure step by step
prior to reassembly and installation
1. Install bearing clip onto main tube. Use guide
hole and the following photo for correct orienta-
tion.
2. Insert main tube into regulator body, long
threads first and stop the travel of the main tube
once the bearing clip is in the center of the regula-
tor body.
3. Install lever arm allowing it to snap into square
holes on either side of main tube. With one hand
on the adjustment side of the main tube, rotate
main tube to assist in installation and locating
each hole for the lever arm.

Assemble Switchover Regulator Main Tube Reassembly – Read this entire procedure step by step prior to reassembly and installation
5. Install or inspect soft seat on inlet valve.
SEAT
If installing a new seat
Check the balance hole in the seat to be sure it
has no flash or is plugged in any way. Press the
seat into the inlet valve. DO NOT LUBRICATE THE
SEAT. Make certain there is NO space between
these two parts. The seat must be pressed all the
way into the inlet valve.
NOTE
Study the features of the inlet valve
assembly. There are four “wings” towards
one end of the assembly and a bore that
creates the balance chamber on the opposite
end.
The wings that align with the lever arm are the two
that have an additional wall for the lever arm to
bear on. The valve assembly should be inserted
into the main tube with these walls toward the
bottom of the regulator tube.
6. Insert the inlet valve, soft seat first, into the main
tube so the inlet valve wings will catch the correct
position of the lever arm as noted above.
Testing correct inlet valve installation:
Using the balance spacer with the O-ring and
spring installed, place into main tube, adjustment
side.
If this is done properly, the lever should lift up once
the spacer makes contact with the inlet valve. If it
does not, the inlet valve has not been inserted cor-
rectly and the wings are not capturing the lever
arm properly.
7. With the main tube still positioned in the center
of the regulator body, use the eraser side of a pen-
cil to gently and steadily push onto the inlet valve
from the adjustment knob side of the main tube.
The lever arm should rise up toward diaphragm
area with this increasing pressure.
8. IMMEDIATELY STOP PUSHING when engage-
ment of the inlet valve wings and lever arm is felt.
Remove pencil and once again use fingers to press

inward on lever arm legs into the main tube. Re-
peat step 6 to confirm correct lever action.
9. Slightly tilt regulator body with the adjustment
knob side down, supply hose/ inlet side up. Inlet
valve should remain in the main tube. If not, repeat
steps 3 to 7.
10. Push/pull on the main tube to locate main tube
to correct position (lever arm should be in the
middle of the regulator body.
11. Install jam nut, main tube and tighten to 12 inch
pounds.
12. Apply a slight amount of non-silicone lubricate
where the O-ring resides on the balance spacer
and insert spring onto spacer.
13. Insert the balance spacer and spring as one
unit into main tube. Repeatedly gently push onto
spacer to confirm lever arm moves up and down in
conjunction with applied pressure.
14. Thread the packing nut onto the main until it
stops.
15. Check operation of lever arm to ensure proper
function (i.e. that it springs back up to raised po-
sition when depressed with thumb and released).
16. Tighten packing nut to 20 inch pounds using a
torque wrench.
17. Press lock clip into groove in packing nut keep-
ing top edge parallel with diaphragm area. Resis-
tance should be felt when installing this clip from
being formed, to provide a locking or jamming
feature. If no resistance is felt, it could mean the
part has lost its spring and should be replaced.
Make sure clip is pressed completely into groove.
18. Turn adjustment nipple clockwise until lever
arm drops just slightly.
1.5.4 Diaphragm and Adjustment
Knob Reassembly
1. Install diaphragm, cover and cover ring. There
should be no gap between cover ring and top of
regulator body when installed correctly.
2. Turn slot shaft in (clockwise) toward regulator
body until inner edge of slot just meets the pack-
ing nut.

3. Install left brace on the adjustment side of the
regulator body.
4. Install male and female knob halves onto the
slot shaft. Added pressure will be required to mate
the two halves.
5. Install adjustment knob screw and tighten un-
til snug. There should be no gap between knob
halves.
6. Install right brace onto the inlet side of the regu-
lator body.
7. Install exhaust whisker firmly in place, mak-
ing sure orientation of outlet ports is correct, as
shown.
1.5.5 Adjusting the Regulator
If cover and diaphragm have not been removed,
do so prior to proceeding.

Adjusting the Regulator Germicidal Cleaning Solutions
1. Turn adjustment knob of regulator in until it
stops, then turn it back out three full turns.
2. Secure a regulated low pressure air supply of
135–150 psig to the switchover regulator.
3. Slowly turn on the air supply and check lever
arm play. With the adjustment knob adjusted out
three full turns, and gas pressure of 135–150 psig
to the inlet valve, there should be ⅛ inch of free
play in the lever and no gas flow.
4. Depress several times, ensure a good flow and
ensure the lever play does not change.
Criteria for optimal setting no more than ⅛ inch
of free play in the lever until gas is heard escaping
from main tube. If criteria are met no adjustment
is necessary.
1.5.5.1 If Adjustment is Necessary
There should be ⅛–¼ inch free travel in the cover
before gas flow starts. When the cover is fully de-
pressed, a strong surge of gas must be heard.
If the purge cover has NO play, or play is greater
than ¼ inch BEFORE GAS flow is heard, the de-
mand regulator requires internal adjustment.
NOTE
Adjustments need to be done with the
adjustment knob out three full turns.
Evaluation of lever play can only happen with sup-
ply gas connected to the regulator and turned on.
Adjustment knob needs to be turned out three full
turns.
1. Turn o the gas supply; bleed o the pressure.
2. Remove the supply hose to expose the slotted
end of the adjustment nipple.
3. Insert a flat head screwdriver into the slot end of
the adjustment nipple
4. Make adjustments as necessary.
Whatever direction is needed, make the adjust-
ment in very small increments and recheck after
each adjustment. Usually ⅛" turn at a time or less
will suce.
NOTE
Decrease lever play by turning nipple out
(counter clockwise) of the main tube.
Increase lever play by turning the nipple in (clock-
wise) to the main tube.
If any problems are encountered that are not eas-
ily fixed it is recommended to perform a complete
disassemble. Perform a meticulous inspection of
the nipple's knife edge. If damage is found replace
and reassemble.
