USE INSTRUCTIONS ExtendAir CO2 Absorbent DOLPHIN & OMG AZIMUTH REBREATHERS Retrofit and load the canister safely in 4 easy steps....

1. Remove the ExtendAir canister from the box. Take one end cap and secure it to either end of the canister by aligning the arrows and rotating clockwise about 1/3 turn. When done correctly the arrow on the cap will point to "locked". Arrows aligned before locking. Arrows indicating locked position.

2. Inspect the foil seal for breaks between the sealing surface and the container rim. Remove the foil seal by tearing it off of the can, and take out the cartridge. Remove the cartridge from the clear-plastic bag. Inspect the cartridge for damage. Check to make sure that the red plug is securely inserted into one end of the cartridge. As mentioned in the Precautionary Notes (below), this is to prevent air flow through the core. If the foil seal has been opened or the cardboard cylinder is torn or punctured, do not use the cartridge. It may have lost the moisture content necessary to function properly. Do not use the cartridge if there is any visible damage to the sides or ends which could cause blockage or leaks.

3. Insert the cartridge into the canister. It does not matter which end is inserted; the cartridge will work properly either way. Secure the remaining end cap as in Step 1. Insert cartridge into the canister

4. Do a pressure check on the canister before installing into the rebreather. Then connect the canister to the rebreather, making sure the hose fittings are connected properly to the inhale and exhale bags. ExtendAir Retrofit Kit successfully installed into Dolphin rebreather. ExtendAir Retrofit Kit successfully installed into Azimuth rebreather.

The installation is now complete. Continue with the normal pre-dive checks on your rebreather.

IMPORTANT ExtendAir® CO2 absorbents are a revolutionary new technology now available for use in SCUBA rebreathers. The absorbent cartridges solve many of the problems associated with traditional granular absorbents. ExtendAir absorbents use the same chemistry as granular absorbents but they are formed into sheets that are rolled into easy to use cartridges. Each cartridge is packaged individually in a sealed container so you only open it when you a re ready to use it. The enclosed instructions pert a i n to the canister and cartridge designed for use in the Drager Dolphin and OMG Azimuth semi-closed circuit rebreathers. Only divers trained in the use of the rebreathers by an accredited training organization should use this canister. ExtendAir cartridges are not a drop in replacement for granules and there f o re cannot be used in existing granular canisters. ExtendAir canisters are designed to be used in conjunction with a specific cartridge. You must make sure that the cartridge you buy is the c o rrect part number to be used with your canister. The ExtendAir canister has been tested in lab conditions at a breathing rate of 40 liters/minute and 1 ATM at 55¡F. The resulting duration is longer than 120 minutes to 1% CO2 at those conditions. As you know from your rebreather training, canister duration varies with dive conditions. It is recommended that you replace the cartridge on or before dive time reaches 120 minutes.  PRECAUTIONARY NOTES ExtendAir canisters work differently from granular canisters in that they are very dependent on uniform airflow. It is therefore important that the diver understands the components in the canister. The end caps have been designed to insure even flow through each channel in the cartridge. Uniform airflow through the cartridge insures that the absorbent is used at an even pace. Anything that disrupts the flow will shorten the life of the cartridge. The seals in the end caps prevent breathing gases from going around the absorbent which would also shorten the duration. All seals and O-rings in the end caps should be replaced annually. As with all O-rings on any rebreather, make sure to properly lubricate them with O2 compatible lube. A canister maintenance kit is available. The ExtendAir CO2 absorbent cartridge comes in an airtight package. All absorbents must be stored in airtight packaging to maintain proper moisture content. For this reason, never use a cartridge if the packaging has been visibly damaged. If the foil seal on top of the container has been punctured or torn do not use that cartridge, as perf o rmance will be compromised. The core of the cartridge is a hollow tube with a red plug in it to prevent flow through the core. Make sure the red core plug is in place and is not damaged. Prior to loading the cartridge into the canister, inspect it on both ends to make sure the channels do not have any obstructions . Each channel must be clear for proper performance .
