Scrubber Checklist
-
Refill Scrubber Y / N ?
-
Fill Cannister using a 2 stage "fill and tap" process. Top up to 6mm from rim (evenly). Install scrim.
-
Clean and grease o-ring. Insert. Clean spacer. Insert.
-
Clean lid and lid O-ring. Grease if needed.
-
Insert scrubber into canister and push to feel loose fitting.
-
Sofnolime used since last refill (in hrs)
-
Bagpipe test on assembled scrubber.
Gases
-
Planned dive location and depth?
-
Diluent cylinder gas analysis
-
Oxygen cylinder gas analysis
-
Lean bailout gas analysis
-
Rich bailout gas analysis
Assembly 1
-
Mouthpiece - gas direction flow & mushroom valves check. Inspect mouthpiece.
-
Attach buzzer. Secure HUD
-
Check O2 & dil MAVs (check o-ring, check hose connection).
-
Close OPV and perform negative pressure test (5 - 10mins).
Controller
-
Switch on. Listen for solenoid clicking, beeps from buzzer. Check all 4 LEDs in HUD active.
-
Record battery voltages B1 & B2. Min 5.5v for batteries. 5.3v = 2 squares.
-
When calibrating, ensure loop is close to 0.21 before starting. Watch for slow cells.
-
Record sensor values just prior to calibrating C1, C2, C3. Cells should be between 0.75 and 1.3 prior to calibrating.
-
Check dil and oxygen MAVs.
-
To perform linearity test - hold open OPV, flush dil through loop for 6 secs. Monitor cells, check low O2 alarm (buzzer & HUD), ppO2 should go down to <0.23 with air dil. Open mouthpiece slightly, inject O2 monitor cells, ppO2 should go to 0.95 - 1.04.
-
Perform linearity test.
-
Ensure correct gas % entered into vision computer and back up (incl bailout).
-
Turn off master/C1, ensure slave/C2 takes over.
Assembly 2
-
Check ADV
-
Check wing
-
Check and breathe bailout (both BOV & bailout cylinder)
-
Check O2 & dil intermediate pressures. O2 7 to 8 bar, dil 8.5 to 9.5 bar.
-
Do positive pressure test.
-
Record cylinder pressures - dil, O2, lean, rich, suit inflate.
-
Close cylinder valves and shut off controller if not diving immediately.
-
Prepare all straps trim weights. Ensure OPV is open after pressure test.
Maintenance
-
Record any maintenance issues here. Record if batteries or cells changed.
