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 should not be used as part of your planned air reserve.

• Monitor diving disorders if ascent rates are exceeded or decompression

stops are missed.

• Practice using SPARE AIR at normal rate ascents in shallow water.

• ALWAYS follow Submersible Systems’ recommended pre-dive standards/post-dive checklist

and annual inspection/repair guidelines.

• 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.

• DO NOT fill or use the SPARE AIR if it has been exposed to extreme heat exceeding 250°F, or

open flame. Instead, discharge the cylinder completely and return it to an Authorized SPARE

AIR Dealer for inspection and possible hydrostatic testing.

• STORE THE SPARE AIR system PRESSURIZED in a cool, dry place. Avoid direct sunlight,

automobile trunks or other areas subject to temperature extremes.

HOW TO FILL SPARE AIR

CAUTION: DO NOT stand directly over SPARE AIR

regulator while filling.

NOTE: Filling too fast can result in an

inaccurate air reading and can damage the

internal components inside the Check Valve.

1. Unscrew black cap from the SPARE AIR Check

Valve filling port.

2. Place the Adapter onto Check Valve and turn the

knurled ring of the adapter to the right until

finger-tight.

NOTE: If air is escaping from the adapter during

filling, close tank valve, wait for air to stop and

re-tighten knurled ring by turning to the right.

WARNING: If the SPARE AIR check valve or adapter threads are damaged or worn

these parts will require replacement. Continued use may cause injury.

NOTE: If adapter knurled ring does not move freely, soak in 1:1 vinegar and water

solution for 3 hours to loosen any salt water corrosion.

NOTE: SCUBA tank must be filled to 3000 psi at beginning of refill procedure. If SCUBA

tank has less than 3000 psi, the pressure indicator will not show full and your SPARE

AIR will not be filled to its recommended full capacity, diminishing available air volume.

3. Attach Adapter to SCUBA tank valve.

4. To fill, , (allowopen SCUBA valve SLOWLY

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 ring of the Adapter to the

left to relieve pressure in the Adapter.

7. Remove Adapter from SCUBA tank and

SPARE AIR.

8. Replace black cap on Check Valve.

SLOWLY

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., )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

WARNING: DO NOT attach or mount the SPARE AIR Holster to your weight belt. The

Holster may interfere with the removal of your weight belt in an emergency, and can

cause loss of the SPARE AIR when you need it most.

BEFORE YOU DIVE

NITROX MODEL 300-N

!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.
