IMPORTANT SAFETY PRECAUTIONS
Submersible Systems, LLC promotes responsible diving practices and the recommendations
that have been promoted by all International Training agencies, including, but not limited to:
• Before any attempt is made to use this product underwater, you MUST have received
TRAINING and CERTIFICATION in the technique of SCUBA diving from a recognized
certification agency. Use of this equipment by a person who is not certified by a recognized
agency shall render all warranties, express or implied, null and void. Use of underwater
breathing devices by uncertified or untrained persons is dangerous and can result in severe
injury or death.
• SPARE AIR is an EMERGENCY alternate air source. It is NOT designed or intended for any
other use. Due to its limited volume, it must not be relied upon as a PRIMARY source of air.

SPARE AIR. Look for an area that has 2 places to
attach the Quick Disconnect Straps (on D-rings,
Straps, etc., )see photos
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.
3. Snap Quick Disconnect Straps around mounting
points on BC and cinch up so Holster is snug against
the BC. and clip other end onto Holster or BC D-ring.
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.
Thread straps through
webbing for best fit

!SPARE AIR is shipped empty - fill prior to use.
!SPARE AIR is always ON and ready for use. The Pressure Indicator Pin should
extend flush with the top of the Pressure Indicator showing that the unit is full. (The
optional Dial Gauge 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 5.
!Push Purge Button down and release. Purge Button should move up and down
freely. To maintain full pressure in SPARE AIR do not purge unnecessarily.
!Make sure SPARE AIR is mounted firmly and adjusted properly in Holster before
entering the water. Velcro must be fully engaged. Be sure the leash is attached to
the SPARE AIR your BCD.AND
!Before diving with SPARE AIR for the first time, practice breathing from the unit,
either above the surface or below the water to become familiar with the product.
The amount of air you will receive will vary based on your lung capacity, depth,
water temperature, etc.
NOTE: Never deplete SPARE AIR entirely in a SIMULATED ascent. Water will enter
inner stages of the regulator and may result in internal corrosion.
COMPATIBILITY
AND USE
!
!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.
!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 OPERATE SPARE AIR
AFTER YOU DIVE
1. Upon ascent, pull D-ring on flap of Holster to open.
5. Continue to inhale and exhale to a safe and normal rate of ascent.
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.
1. Visually check the Pressure Indicator and press Purge Button.
2. White Indicator Pin should be extended and airflow should occur. This ensures
pressure was maintained during your dive.
3. As soon as possible after diving, the SPARE AIR should be removed from its
holster and soaked thoroughly for at least 30 minutes in warm fresh water. Be
sure the SPARE AIR has some pressure in the cylinder to prevent the entrance of
moisture into the system.
4. After the system has been properly soaked, rinse it vigorously by flushing the
cavity of the mouthpiece with a steady stream of water.
5. If necessary, rinse refill adapter in fresh water.
6. Wipe the system and refill adapter as dry as possible with a clean towel and gently
shake to dislodge any water.
7. Store SPARE AIR system pressurized in a cool, dry place. Avoid direct sunlight,
automobile trunks or other areas subject to temperature extremes.
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, LLC for service and/or check-up.
CAUTION: Never use chemicals or solvents to clean SPARE AIR.
!
CAUTION: Begin ascending immediately to avoid using valuable time and air.
!
CAUTION: Failure to purge the SPARE AIR regulator before inhaling will result in
swallowing water.
!
NOTE: SPARE AIR is only for use to recreational depths.

CARE AND MAINTENANCE
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 by an Authorized SPARE AIRANNUALLY
Dealer or by Submersible Systems, LLC.
Prolonged or improper storage can result in internal corrosion and/or deterioration of
O-ring seals. SPARE AIR may require service even if the unit has received little or
no use.
If you notice damage, wear or suspect any leaking or missing parts, have SPARE AIR
examined by an Authorized SPARE AIR Dealer immediately.
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: DO NOT attempt to repair SPARE AIR yourself. Unauthorized repairs or
tampering are hazardous and WILL VOID your warranty.
!
WARNING: NEVER use a hydrocarbon based oil (i.e. household oil or motor oil).
!
Visit www.spareair.com for service locations world-wide.
SPARE AIR used for rental or training purposes in salt, chlorinated, or silted fresh
water, will require complete overhaul and factory prescribed service every three to
six months, or whenever it is suspected that moisture has entered the system. Use in
chlorinated swimming pool water will accelerate the deterioration of most rubber
components, and require more frequent service than in other typical conditions.
If service is unavailable locally, Submersible Systems can perform authorized service
through the mail. Visit our website at www.spareair.com for more details.
