3.10. Scrubber Medium

The O2ptima CCR has been designed to use Extendair cartridges manufactured by

Micropore. The Extendair absorbent use the same chemistry as granular absorbents but

they are formed into sheets that are rolled into easy to use cartridges.

The Extendair cartridge has been extensively tested in order to determine maximum

duration of the scrubber material. For dives within recreational dive limits (< 130ft, no-

decompression) the Extendair cartridge can be used for a period of up to two (2) hours in

cold water (50 F) and three (3) hours in warm water (70 F).

WARNING!!! REPLACE SCRUBBER CARTRIDGE EVERY THREE (3) HOURS

WHEN DIVING WITHIN RECREATIONAL LIMITS IN WARM WATER.

WARNING!!! REPLACE SCRUBBER CARTRIDGE EVERY TWO (2) HOURS WHEN

DIVING WITHIN RECREATIONAL LIMITS IN COLD WATER.

WARNING!!! REPLACE SCRUBBER CARTRIDGE IF LEFT IDLE IN THE UNIT

FOR A PERIOD OF MORE THAN TWENTY FOUR (24) HOURS.

WARNING!!! REPLACE SCRUBBER EVERY THREE (3) DIVES EVEN IF

SCRUBBER DURATION IS NOT FULLY USED.

WARNING!!! FOR DIVES PAST RECREATIONAL DIVE LIMITS, CONSULT TEST

DATA RESULTS FOR SCRUBBER DURATION. RESULTS CAN BE FOUND ON

MICROPORE WEBSITE (www.extendair.com).

3.11. Electronics

The electronics must be rinsed in fresh water after every use. The battery cap is used to

transmit the power signal from the battery to the electronics therefore it is critical that the

battery cap threads and battery spring be cleaned regularly. Any accumulation of deposits

will affect battery consumption.

The o-rings on the handsets should be inspected regularly and replaced every twelve (12)

months.
