8.3.1 Start up Procedure
1. Change Soda lime canisters as described in Section 8.5.5 and note time of canister
change on Control Console panel.
2. Ensure that all shut off valves in the system are open and one Soda lime canister
is on line.
3. Check booster oil level and top up with recommended lubricant if necessary.
4. Check water level in booster header tank, top up with glycol water mix if
necessary.
5. Turn on seawater cooling supply booster.
6. Turn on cooling supply to Reprocessing Unit.
7. Set Control Console BPR loader, O 2 regulator and make-up regulator for the
proposed diving depth according to Section 8.6.
8. Crack the exhaust cross-connect valve and allow the exhaust umbilical pressure
to rise to the correct value for the proposed dive, then close valve. This is the BPR
loader pressure specified in Section 8.6.
9. Ensuring that both stop/lock buttons are pulled out, switch on main isolator on
booster starter panel. (Fault lights will illuminate).
10. Press reset button on booster starter panel. (fault lights will go out).
11. Select local or remote operation.
12. Start booster from the indicated station.
13. Check booster oil pressure. If gauge does not reach 50 psi (3.4 bar) within 30
seconds, stop machine and investigate cause. (with excessively low oil pressure the
booster will stop automatically due to pressure switches in the control circuit).
14. Check gas quality by allowing gas to flow from the Reprocessing Unit sample
regulator through the O 2 and CO 2 analysers in dive control.
15. The unit is now ready to supply reclaimed gas to the diver.
16. The gas booster will circulate gas around itself until such time as a diver starts
breathing on recovery at which time the booster will automatically adjust to meet the
diver’s breathing requirements.
17. Initiate pre dive check off Bell Equipment and diver equipment (see bell check off
lists in the following pages).
