• Recommended Max ascent rates: 15 meters per minute (6 meters per minute
for the last 6 meters).
• Swimming diver accepted as 25 Iiters/min., non-swimming will be less.

• NEVER dive with a SPARE AIR system that shows signs of damage, leakage or
substandard performance.
• NEVER OVERFILL the SPARE AIR system above 3000 psi, the air pressure
stamped on the cylinder. ONLY use purified, dry compressed breathing air when
refilling SPARE AIR.
• STORE THE SPARE AIR system PRESSURIZED in a cool, dry place. Avoid

BEFORE YOU DIVE WITH SPARE AIR
• SPARE AIR shipped empty - fill prior to use.
SPARE AIR is always ON and ready for use. The White Pressure
Indicator Pin should extend flush with the top of the Pressure
Indicator Gauge indicating that the unit is full. (The optional Dial
Gauge indicator will show full when dial is at “3”.) If Pressure
Indicator Pin is less than flush SPARE AIR MUST be refilled. Do not
dive until you have refilled SPARE AIR. See refilling instructions on
page 12.
Push Purge Button down and release. Purge Button should move
up and down freely. To maintain full pressure in SPARE AIR do not
use purge unnecessarily.
Make sure SPARE AIR is mounted firmly and adjusted properly in
Holster before entering the water. Velcro must be fully engaged.
NOTE: For added security
a
safety leash/lanyard is
recommended so that SPARE AIR is not lost if it is dislodged,
dropped or released by accident. Hold SPARE AIR secure
with a free hand on entry into the water or in rough surf or
currents.
HOW TO MOUNT SPARE AIR
1. Determine where on BC you would like to mount SPARE AIR.
Look for an area that has 2 places to attach the Quick
Disconnect Straps (on D-rings, Straps, etc.)
2. The Straps are movable by threading them through any of the
webbing sections on back of Holster. Choose the 2 that would
allow for the tightest fit possible.
7
3. Snap Quick Disconnect Straps around mounting point on BC
and cinch up so Holster is snug against the BC.
4. Attach SPARE AIR leash snug around neck of cylinder and clip
other end onto Holster or BC D-ring.
5. Insert SPARE AIR into Holster and secure velcro on top flap,
attach Mouthpiece Cover.
6. Try on BC and try removal of SPARE AIR several times to become
comfortable with the steps necessary to remove the unit.
HOW TO OPERATE SPARE AIR
1. Upon ascent, pull D-ring on flap of Holster to open.
CAUTION: Begin ascending immediately to avoid using
valuable time and air.
2. Grab SPARE AIR regulator head and pull out of the Holster. This
action will release the Mouthpiece Cover.
3. Place SPARE AIR into user’s mouth.
4. Press Purge Button lightly or exhale sharply to clear regulator
before inhaling.
CAUTION: Failure to purge the SPARE AIR regulator before
inhaling will result in swallowing water.
5. Continue to inhale and exhale to a safe and normal rising rate of
ascent.
NOTE: SPARE AIR is only for use to recreational depths.
Never deplete SPARE AIR entirely in a SIMULATED ascent,
water will enter inner stages of regulator and may result in
internal corrosion.

Why did you purchase SPARE AIR? ___________________________________________________
____________________________________________________________________________________________
AFTER YOU DIVE WITH SPARE AIR
1. Visually check the Pressure Indicator Gauge and press Purge
Button.
2. White Indicator Pin should be extended and airflow should occur.
This ensures pressure was maintained during your dive.
NOTE: If Indicator Pin is not extended or no air flow occurs,
water and contaminants may have entered the regulator’s
internal stage and could lead to corrosion and/or failure of the
system. Contact your Authorized SPARE AIR Dealer or
Submersible Systems, Inc. for service and/or check-up.
3. Remove SPARE AIR from the Holster to rinse and dry.
4. With pressure in the SPARE AIR, rinse or soak in fresh water for 30
minutes and run fresh water inside the mouthpiece and around the
regulator.
5. Shake excess water from the system and dry thoroughly.
CAUTION: Never use chemicals or solvents to clean SPARE AIR.
PRODUCT COMPATIBILITY
AND USE WITH NITROX–MODEL 300-N
• Submersible Systems Nitrox SPARE AIR shall not be used with Pure
Oxygen, or Nitrox with greater than 40% Oxygen.
• Only gas from storage and supply equipment cleaned and
maintained for Oxygen Service is acceptable for use with Nitrox
SPARE AIR.
9
• If the SPARE AIR Nitrox is used with equipment or connected to air
supply systems which are not rated for Oxygen Service, it will be
considered contaminated and will require cleaning for Oxygen
Service prior to use again with Nitrox.
• Equipment users must be trained and certified in the specific use of
Nitrox by dive industry training agencies.
• Only a halocarbon based lubricant such as Christo-Lube MCG 111
should be used on SPARE AIR Nitrox.
HOW TO CARE FOR YOUR SPARE AIR
Providing the best possible preventative maintenance and
following routine pre- and post-dive steps diligently will help to
ensure the maximum life of your SPARE AIR system. SPARE AIR
should be serviced ANNUALLY by an Authorized SPARE AIR
Dealer or by Submersible Systems, Inc.
If you notice damage, wear or suspect any leaking or missing
parts, have SPARE AIR examined by an Authorized SPARE AIR
Dealer immediately.
WARNING: DO NOT attempt to repair SPARE AIR yourself.
Unauthorized repairs or tampering are hazardous and WILL
VOID your warranty.
The SPARE AIR cylinder has a DOT 3AL3000 rating and will require
HYDROSTATIC TESTING EVERY FIVE (5) YEARS and a VISUAL
INSPECTION ANNUALLY. Keep the Threads on both the Check
Valve and Refill Adapter clean and lubricated. Use a high-quality,
non-toxic, food grade spray silicone for best results.
WARNING: NEVER use a hydrocarbon based oil (i.e.
household oil or motor oil).
10
HOW TO TRAVEL WITH SPARE AIR
1. When taking Spare Air on commercial aircraft TSA
(Transportation Security Administration) requires air cylinders to
be empty. Purge Spare Air until empty of air.
2. Remove regulator from cylinder (they are attached hand tight) by
turning counter clock-wise. Leave o-ring, washer etc. on the
regulator.
3. Pack Spare Air in your check on luggage (NOT carry on).
4. Notify counter personnel when checking in for your flight that you
have a Spare Air mini-breathing system that is empty and
disassemble in your luggage.
5. When you reach your dive destination, reassemble Spare Air and
refill.You may lightly lubricate the tank 0-ring with a small amount
of silicone spray or grease – never use a hydrocarbon based oil.
Do not force regulator onto tank – if you feel resistance stop and
unscrew and start again.
6. Replace tank o-ring after product has been disassembled and re-
assembled 3 times, or o-ring shows signs of wear or air leakage.
7. Keep Spare Air regulator and cylinder threads clean and dry.
Note: We recommend the purchase of the SPARE AIR Travel
Pack #963 which includes a durable plastic carrying bag, 3
extra tank o-rings and protective caps for the regulator and
cylinder threads (go to website for more information).
Note: This product, Spare Air, is an emergency breathing
system that utilizes breathing air and is not hazardous.
11
HOW TO REFILL SPARE AIR
NOTE: Always refill SPARE AIR immediately after use,
so the system is ready for subsequent use.
CAUTION: DO NOT stand directly over top of
SPARE AIR regulator while filling.
A feature of this adapter is that as you rotate the knurled ring
on the adapter to the right it automatically closes the vent.
When unscrewing to the left it vents the pressure, allowing the
adapter to unscrew easily.
1. Unscrew black knurled Cap from the SPARE AIR Check
Valve filling port.
2. Place the Adapter onto Check Valve and turn the knurled
part of the adapter to the right until finger tight.
3. Attach Adapter to SCUBA tank valve.
4. Fill (Important: Gently open SCUBA valve to fill slowly, take
45 – 60 seconds to fill). The pin on the Pressure Indicator
will rise while filling and when flush with the top unit is full
at 3000 psi. For Dial Gauge option, unit is full when needle
points to 3.
5. Close SCUBA tank valve.
6. Turn the knurled part of the Adapter to the left to relieve
pressure in the adapter.
12
7. Remove Adapter from SCUBA tank and SPARE AIR.
8. Replace black knurled Cap on Check Valve.
NOTE: If air is escaping from the adapter during filling,
close tank valve, wait for air to stop and retighten
knurled ring by turning to the right.
NOTE: If SCUBA tank WAS NOT FULL at beginning of
refill procedure, then the pressure indicator will not
show full and your SPARE AIR will not be filled to its
recommended full capacity, diminishing available air
volume.
WARNING: If the SPARE AIR check valve or adapter
threads are damaged or worn these parts will require
replacement. Continued use may cause injury.
