STOP!
Before using this system or engaging in any underwater activities you must
ensure:
1) you are in good physical health
2) you are in good mental health
3) you have been properly trained
4) you know the potential risks of diving
MEDICAL CLEARANCE/POTENTIAL RISKS
Divingcanbeoneofthemostexcitingandrewardingactivitiesyouwilleverexperience.However,likemostexciting
activities, there are rules and procedures you must follow. Proper training is crucial to minimize risk and maximize
enjoyment. Breathing in an underwater environment can be dangerous, or even deadly, if you don’t know the rules or if you
chose to ignore them.
Please refer to the RSTC Medical Statement and Guidelines for Recreational Scuba Divers Physical Examination included
withthismanual.YoushouldcompleteallportionsofthemedicalstatementincludingtheDiversMedicalQuestionnaire.
One form is included for each diver set-up in your system package. You may photocopy the form as needed or download
additionalcopiesdirectlyfromwww.browniedive.com/training/medical.shtml.Pleasekeepthisinformationonleforfuture
reference and to review with your doctor or any professional diving instructor.
The purpose of the Divers Medical Questionnaireistondoutifyoushouldbeexaminedbyyourdoctorbeforeparticipat-
ing in recreational diver training. A positive response to a question does not necessarily disqualify you from diving. A positive
response means that there is a preexisting condition that may affect your safety while diving and you must seek the advice
of your physician prior to engaging in dive activities. Please answer the following questions on your past or present medical
history with a YES or NO. If you are not sure, answer YES. If any of these items apply to you or you are not sure, we must
request that you consult with a physician prior to participating in SSA (surface supplied air) diving. Take the RSTC Medical
Statement and Guidelines for Recreational Scuba Diver’s Physical Examination to your physician.(Note: If you have already
had a medical exam for diving within one year of the start of training, and had a physician give his or her approval at that
time, you may bring a photocopy of the RSTC Medical Statement form your physician signed at that time, in lieu of obtaining
a new form.) 4
WHEN YOU RECEIVE YOUR NEW COMPRESSOR SYSTEM
1. Inspect the contents to be sure everything is included.
2. Contact your dealer within 5 days of receipt should your equipment be damaged or missing.
3. Read and understand the information in this owner’s manual and the engine owner’s manual before operating.

CONGRATULATIONS ON YOUR PURCHASE OF A BROWNIE’S THIRD LUNG!!
Younowhaveinyourpossessionthenest,mostreliable,surfacesuppliedbreathingairsystemavailable.Theoperationis
designed with your safety and convenience in mind, and by carefully reading this brief Manual you can be assured of many
hours of trouble-free enjoyment.

AFTER THE ONLINE COURSE IS COMPLETED
It is time to visit your local dive store for the in-water training phase.
The online course will provide academic knowledge. To complete your training you’ll need to practice that knowledge in
a controlled environment before venturing into open water. The course website, www.scuba-training.net, includes a list of
afliatedindependentscubainstructorsandprofessionaldivestoresbygeographicregion.Youshouldenrollinanin-water
skills course with a professional scuba instructor to review your academic knowledge and practice your water skills. Your
instructor will review with you the topics covered in the online course and evaluate your comprehension of the course
content. Next, they will arrange a series of dives in a controlled environment (usually a pool) to practice breathing through
aregulatorandotherwaterskills.Heorshewillsharetechniquestoimproveyourefciencyandcomfortinthewater.By
working closely with your instructor, you will become a better (and safer) diver.
ONLINE TRAINING
In the interest of sharing the most accurate and up-to-date information on accepted diving practices, Brownie’s
Third Lung has teamed up with Scuba-Training.net to provide free online dive training with the purchase of each
Surface Supplied Hookah System.
The program is an interactive, web-based learning course designed to teach you how to properly and safely use your
hookahsystem.Itisbrokendowninto7moduleseachwithspecicKnowledgeRequirementsandObjectives.
The course utilizes a variety of written explanations, illustrations, photographs and streaming video to clearly convey each
subject. Brownie’s makes it easy for students of all ages, including children, to enjoy learning.
Each chapter concludes with a multiple choice quiz to test your understanding and comprehension of the topics covered.
Incorrect answers are automatically reviewed and retested. Once you have successfully completed the quiz for that module,
youcanmoveontothenextmodule.Afterallchaptersandquizzeshavebeencompletedthereisanalcomprehensive
exam.Thenalexamfollowsthesameformatasthequizzesandmayberetakenuntilitissuccessfullycompleted.

WARNING: IMPROPER USE OF ANY UNDERWATER DIVING EQUIPMENT CAN RESULT IN SERIOUS
INJURY OR DEATH. DO NOT DIVE WITHOUT PROPER TRAINING.

Your Third Lung is designed for shallow water, unobstructed diving and should never be used in enclosed areas, such as
caves, shipwrecks or ledge overhangs. The Third Lung is stable in calm sea conditions. Care should be exercised when
conditions are rough to avoid swamping or inverting the unit. Breaking waves, similar to those found in the surf zone, may
invert or swamp the Third Lung. Care should be exercised when such conditions exist.
SETTING UP
GASOLINE POWERED UNITS ARE SHIPPED AND/OR DELIVERED WITH OIL AND GAS REMOVED from the engine.
RefertotheEngineOwner’sManual,whichisenclosed,forllingandmaintenanceprocedures.Note: Use only unleaded
fuel containing no more than 10% ethanol.
WARNING: DO NOT POUR OIL INTO COMPRESSOR. THIS WILL CONTAMINATE THE COMPRESSOR
AND RUIN IT FOR AIR BREATHING. BREATHING FROM A COMPRESSOR THAT HAS HAD OIL
MISTAKENLY ADDED MAY RESULT IN SERIOUS INJURY. DO NOT SPRAY CORROSION X OR ANY
PETROLEUM BASED PRODUCT ON, IN, OR AROUND THE COMPRESSOR.
Theremoteintakestaffisdesignedtoincreasecompressorlifebymakingitdifcultforwatertointrudeintothecompressor.
Anadditionalbenet,isthatitfurthereliminatesthepossibilityofexhaustfumesenteringthebreathingair.Evenso,
precautions must still be taken to ensure a totally pure air supply. Never operate the equipment in a toxic fume environment
suchasnearrunningoutboardengines,exposedchemicalsorfuelspills.TheunitisforOUTDOORUSEONLYandshould
never be run in an enclosed area.
STEP 1
Remove the dust cap from the socket located on top of the compressor, slip the clear PVC staff into the socket as far as it
will go to create a watertight seal in the socket. The dust cap, tied to the socket, must ALWAYS BE IN PLACE WHEN THE
STAFFISREMOVED.Ifnot,watercansplashdirectlyintothecompressorhead.
STEP 2
CHECKING/ADDING OIL
1. Check oil daily before use. There is a hole in the side of the pan for easy access (Figure 1). Reach through the hole
in the side of the pan (Figure 2) and, unscrew the dipstick going counter-clockwise. Remove the dipstick (Figure 3)
and check that the oil level falls inbetween the two hash marks (Figure 4).If it does replace the dipstick and continue.
 2.Thesystemwillhold1pintofoil.Ifthesystemisbrandnewandyouareaddingoilforthersttime,measureout
1 pint of automotive detergent oil (SAE30 or 10W30). Insert the funnel into the oil reservoir and slowly pour the oil
in (Figure 5). Completely screw the oil cap back in and remove one time to check the oil level. Make sure it falls
inbetween the two hash marks on the dipstick.

1. Lift Velcoaponthesideofthe
tube cover.
2. Turn the valve cover counter-
clockwise exposing the valve.
3.Inserttheinationnozzleintothe
valve and turn clockwise to lock.
4. Located at the end of the black
heathoseisamaleQRStting
whichtssnuglyintothecleartube.
With the compressor running, insert
themaleQRSttingintotheclear
tubeandbeginlling.
5.Atabouthalfwaythroughthelling
process, check to see that the tube
is positioned uniformly in the cover.
Filluntiltubeisrmtothetouch,but
avoidoverlling.Shutoffengineby
turning kill switch to “Off.”
6. Press fabric cover back into place
andcliptheinationnozzleonto
availableD-ring.
7.Deationisveryquickandeasy.
Remove the valve cover by turn-
ing counter clockwise and simply
depressthequick-deatebuttonin
the center of the valve. You may also
lock the valve open by depressing
thequick-deatebuttonandturning
it clockwise. Replace valve cap, turn
clockwise to secure. Press fabric
cover back into place. Turn engine
off until you are ready to launch the
unit.

THE TUBE INFLATION AND DEFLATION
STEP 3
STARTING THE UNIT
Serious burns may resulting from touching hot surfaces of the Engine. Please read the Engine Owner’s Manual.
1. Make sure the oil reservoir and gas tanks are full. Refer to your Engine Owner’s Manual.
2. Put the fuel switch in the “ON” position.
3. Turn the kill switch to “ON.” Start the engine.
4. If it is cold, it might be necessary to choke it. As it warms, return the choke to the open position.

STEP 5
MOUNTING.
Feed heat hose through oval hole in bottom of pan and also through the middle of the tube. Place entire pan into the tube.
The mounting straps on the compressor pan are lined up with corresponding straps on the tube cover. Snap the buckles
together and adjust straps. Keep snug to prevent slipping.
STEP 6
HEAT HOSE
Snap the 60-foot down line to the black heat hose. Unreel rather than uncoil the
hoseonthedeck.EvenwiththeQRSttingsitisbesttoeliminateasmanycoil
loops as possible.
STEP 7
HOSES
For one diver, snap one or more of the 20-foot diver hoses directly to the 60-foot
down line. For two, snap oneQRSYdividertothe60-foot,commonhose;then
snap the two 20 foot diver hoses to the Y divider. Snap the regulator to the end
of the diver hoses. For three divers, snap twoQRShosedividerstothe60-foot,
commonhose;then,snapthethree20-footdiverhosestotheYdividers.Again,
snap the regulator to the end of the diver hoses. For four divers, snap three
QRShosedividerstothe60-footdownline.Then,youshouldfollowthesamepatternaspreviouslystated.
STEP 8
HOW TO ADJUST THE DROP WEIGHT CUMMERBELT:
1. Unclip the front buckle
2. Undo the Velcro underneath the buckle
3. Laythebeltatopen.Unzipthesleevelocatedonthebackofthebelt.You
will see that there is a piece of elastic with the Velcro adjustments on both
sides. The belt should be adjusted evenly on both sides so the front buckle
is centered across the mid-section. Simply undo the Velcro and re-adjust
themtotthewaistofthediver.(*Forextremelysmallwaistdivers:Youcan
switch the ends of the belt from opposite stainless steel loops to the loops
thatarenexttoeachother.SeeFigure6,bottombeltcongurationwill
reduce belt size by approximately 3 inches.) Zip the sleeve back up.
4. Unclip the buckles that hold the drop weight pockets in place. Each pocket can hold up to 10 lbs. of weight. We
recommend using soft lead shot weights rather than hard weights as they conform better to the shape of the
pocket. See Figure 7. Undo the Velcro and distribute the weight evenly into each pocket, then re-Velcro.
5. Reinsert the pockets matching the bend in the pocket to the bend
in the belt itself, and reconnect the buckles. See Figures 8 and 9.

Figure 8 Figure 9
STEP 9
HOW TO USE THE DROP WEIGHT CUMMERBELT WITH AN EGRESSOR PACKAGE:
1. Follow above steps 1-5.
2. Then unzip the sleeve that came with the Cummerbelt, and put aside. You will no
longer need this sleeve unless there are times that you choose to dive without the
Egressor scuba system.
3. Zip new sleeve onto the belt with the Brownie’s logo facing upright. See Figure 11.
4. Mount the regulator onto the tank and insert the cylinder with the valve pointing
outward. There are two strips of Velcro that should be attached in a criss-cross
fashion around the cylinders neck. See Figure 12.
5. Turn the system on.
6. The mouthpiece has a bungee necklace attached so the regulator may hang easily around the neck for quick
retrieval in an out of air situation. See Figure 10.

STEP 10
LAUNCHING
BOAT LAUNCHING
 1. Placethecompressorassemblyintotheoatandfastenconnections.
2. Run the heat transfer hose through the center hole.
3. Snap the 60-foot down line to the heat hose.
 4. Lowertheoatintothewater.
5. Start the unit.The pressure release valve on the compressor should evacuate a sporadic puff of air or a light con-
tinuousow.Breathingontheregulatorsshouldstoptheowindicatingthattheairisbeingproperlyregulated.
6. Push the unit into the current or wind and allow it to drift the length of the hose.
7. Snap on Y divider(s) if needed and diver hose(s) and snap regulator hoses to belts.
8. Reverse procedure for returning to the boat.
9

BEACH LAUNCHING
 1. Whenlaunchingfromthebeach,rstdeterminewhetherthesurfwillallowsafeentry.
 2. Breakingsurfmayiptheunit.HavingagripIontheunitinandoutofsurfzoneisessential.
 3. DONOTLETREGULATORSDRAGINTHESAND.Theoatisequippedwithstrapstosecureallhosesforeasy
carrying.
4. Start the unit on the beach or in calm, waist deep water. The pressure release valve on the compressor should
evacuateasporadicpuffofairoralightcontinuousow.Breathingontheregulatorsshouldstoptheowindicating
that the air is being properly regulated.
6. Push the unit into the current or wind and allow it to drift the length of the hose.
 5. Deploythediverhosesattachingthemtothebelts.
6. Swim the unit well away from the breaking surf. Remember, the wind may blow the unit back into the surf.
7. Play out the 60-foot down line spinning out any kinks.
8. Reverse procedure for returning to the beach.
STEP 11
USING AS A DECK MOUNT
Whenusingasadeckmount,orwheninatingthetube,positiontheunitso
that the exhaust is pointing downwind and that there is plenty of circulating air
available to cool the engine. Also make sure that the exhaust is not too close
to the gunwale (gunnel) to prevent exhaust from bouncing back into the intake
air.Theunit’sdesignisusuallysufcienttopreventthisbutbeingawareofthe
situation will totally ensure the air quality.
If the unit is used often as a deck mount, you might consider ordering hose
extensionstogetadditionalrangeawayfromtheboat.WiththeQRSttings,
adding additional hoses is literally a snap.
STEP 12
SOME TIPS ON USE OF THE EQUIPMENT
Sudden bursts of energy might use up more air volume than the compressor can supply. This will result in restrictive breath-
ing.Ifyouencounterthis,simplySLOWDOWNyourbreathingorrefrainfromexertinggreatamountsofenergyuntilyour
respirationratebecomesnormalized.Excitement,activitylevel,currentow,depthandexperiencelevelofdiverswilldictate
your dive.
STEP 13
THE CLEAN UP AFTER YOUR DIVE DAY
1. After the engine has cooled down, and with the air intake assembly in place start up the engine.
2. Thoroughly spray down the entire unit with fresh water WITH THE ENGINE RUNNING.
 3. Donotforcewaterintothecompressorairintakeorintotheengineaircleaner.
4. Fresh water can be safely sprayed over the rest of the unit, including into the pull cord housing of the engine, which
is where salt laden air is drawn in for cooling purposes.
5. Wash the engine thoroughly including all the linkage. When you feel certain that you have completely washed off
and out, all the corrosive matter, continue washing the rest of the system, including all the hoses, belts, tube and
regulators. You may purge the regulator and wash it down ONLY while the unit is on and running, otherwise you
mayoodtheregulator.
6. Blow-dry the engine and compressor. (Handy blower is included in Care Kit).
 7. ApplyaverylightcoatofCorrosionX(suppliedwithCareKit)toengineonly.Donotsprayonthecompressor.
8. Turn off the gas feed switch and allow the engine to run until it shuts off. Unscrew the bolt underneath the carbure-
tor to drain the gas. (Remember that you will need to have some sort of container to catch the fuel as it is drain-
ing.) After the gas has drained out replace the bolt and turn the on/off switch to the off position. This will keep the
carburetor clean.
9. Add Stabil (supplied with Care Kit) to the gas if it is to be stored for more than a week (more information on storage
in next section).
10. Before disconnecting hoses and regulators make sure to release pressure in lines by purging regulators.
