IMPORTANT!!! When re-assembling the DSV, extreme care should be taken to ensure

the valves have been put in the proper orientation for air loop flow. The long hose with red

connector should be on the inhalation side and the long hose with black connector should

be on the exhalation side. A mushroom valve check should perform after reassembly.

3.5. O-Rings

The O2ptima CCR has multiple o-rings contained within the breathing loop. All o-rings

should be changed on a yearly basis or sooner if degradation is seen. The canister has nine

(9) o-rings and the breathing loop has sixteen (16) o-rings that need to be periodically

inspected and replaced each year. The reason for such a high o-ring count in the O2ptima

CCR is that the majority of fittings have double o-ring fittings.

3.6. Batteries

The recommended battery for the O2ptima CCR electronics is the 3.6 Volt Saft Lithium

Ion (Saft P/N: LS14500-10). Many factors affect battery life such as the frequency of the

solenoid firing and back lighting for the electronics. It is recommended that the battery be

replaced every 6 hours of diving but careful attention should be used if dive profiles require

a high frequency of solenoid firing or long duration of back lighting.

If the unit is not going to be used for an extended period of time (more than 24 hours), it is

recommended to remove the batteries to conserve power.

WARNING! WHEN THE BATTERIES ARE REMOVED FROM THE HANDSETS,

ALL TISSUE INFORMATION IS LOST. A SURFACE INTERVAL OF 24 HRS IS

REQUIRED PRIOR TO USING THE HAMMERHEAD ELECTRONICS TO PROVIDE

DECOMPRESSION INFORMATION.

Additional information on batteries can be found in the HammerHead manual.

3.7. Wiring Harness

The wiring harness relays the electrical signal from each of the cells to the main connection

block inside the head. It is critical that a good electrical contact is made between the

connection block and the head. Improper connection can lead to erroneous oxygen levels

or the inability to calibrate a specific cell.

The banana jack connectors and receptacles should be cleaned every 20 hours of use or any

time excessive moisture or flooding has occurred. The wiring harness should be replaced
