-
Clean and dust free
-
Dry and clean
-
O-ring lubed and correct in place
-
Diluent and O2 connected?
-
ADV Function OK
-
OPV function and set to dive
03. Scrubber components
-
Is the scrubber dry
-
How many hours has the scrubber been used for
-
Install scrubber and ensure all spacers and o-rings are lubrocated and in place
-
Install scrubber cover
04. Scrubber cover

-
Place head plate with o-ring and secure screwed down
06. Assembly
-
Counter lung and Scrubber in place with mid-section. Head aligned. Clips closed.OPV set to dive. O2 + DIL hoses connected.
-
Check cylinder mount - locked and ensure they are in the correct positions
-
OPV set to Dive?
07. Calibrate steps
-
Calibrate with cap and 100% O2
-
mV DIL - sensor; 1 - 2 - 3
-
mV O2 - sensor; 1 - 2 - 3
-
Is handset functioning correctly
-
Are batteries working
-
Is correct gas visible
-
Check manuel add - both DIL and O2
08. Breating Loop
-
BOV function - OC/CC - correct?
-
Flow: Right to left / flapper valves working
09. Connect LOOP
-
Flow right to left?
-
Connect loop to head - secure screws
-
Connect BOV hose
-
Slowly turn on O2 and Dil mix
-
Check voltage for computer and solinoid
10. Pressure tests
-
Perform positive pressure test - turn off valves and breathe in to loop, close and wait 120 sec.
-
Perform negative pressure test - breathe gas from loop to completly empty, clos and wait 120 sec.
-
Check shut off valves - both DIL and O2
-
Perform pressure drop test; Turn on computers, switch to surface po2 (0.19). Open DIL and O2 valves SLOWLY. Circulate gas in loop. Close valves and ensure NO pressure drop in entire system.
11. Pre-breathing
-
Recheck settings on handset, low SP 0.7 - CC/OC, BOV function.
-
Pre breathe in min. 3 min.
-
Does the ADV work
-
Confirm what position the OPV will be left in (dive)<br>
12. Last check - on site, before entering water
-
Handset correct DIL, gradient, bailout options and set-point?
-
All valves open
-
Lead?
-
Lights and heating on board
-
Mirror for bubble check
