rEvo Build Checklist

Wake up electronics (open and exposed, never sealed)

Record Cell mVolts at ambient air

Record Cell #1 mV

Record Cell #2 mV

Record Cell #3 mV

Check EXT battery - fire solenoid for 10 seconds > 6.5V

Record EXT battery mV >6.5

Check oxygen sensor life . < 7 months , if not replace and date

Analyze DIL and OXY gases

Record Oxygen%

Record Diluent %

Connect tank and valves

Install moisture pads

Fill or check time on scrubber. Top marker on exhale/top. RMS arrow up.

Close Cover

Loop check/non return valves check

Suck and blow test - confirm one way only with seal

Install Loop

Wrap and install HUD

Turn ON/OFF Dil and OXY

Record DIL pressure (psi or bar)

Record OXY pressure (psi or bar)

Positive Check

Close DSV

Despressurize DIL/OXY until gauge reads 0

Listen to OPV operation

Listen for any leaks (2-3 minutes)

Open DSV and listen for positive (woosh)

Negative Check

Suck negative - closing DSV on large inhale

Look for hose scrunched together (2-3 minutes)

Open DSV listen for negative "suction"

Calibrate Shearwater

Turn on oxygen

Turn on Shearwater - confirm oxygen % in system setup

Inflate O2 full, suck empty, repeat 3-4 times, watch Po2 max out, and Mv max out

Close DSV - open "crack" vent out line pressure

Record Cell #1 mV

Record Cell #2 mV

Record Cell #3 mV

Close DSV - Open "crack" to vent out line pressure

Confirm calibrate on Shearwater

Calibrate rEvo Dream - immediately upon Cal of Shearwater

Confirm oxygen on Shearwater to adjust oxygen on Dream to match - see manual

3 Pushes to access "P-5"

Record Cell #1 mV

Record Cell #2 mV (if applicable)

Confirm Battery Life

< ____ Hours Operation or factory replace battery

Close DSV fully

Shut rEvoDream off within 2 minutes to conserve battery

Oral inflate wing to max (check for leaks)

2-3 min breath check /or shut down and ready for dive mode

Bail Out Check

Check valve is in off position

Suck gently to confirm "no leak" diaphragms

Turn valve on - record pressure (psi or bar)

Breath bail out regulator

Record bail out gas mixture

Confirm bail out gas in Shearwater
