* At the end of the dive: always keep the mouthpiece in your mouth and your diving 
mask on, until you are entirely on dry land: always pay attention that the HUD's green 
LED's  are  burning!  If  you  have  to  remove  the  mouthpiece  at  the  surface,  take  care 
that  the  mouthpiece  is  ALWAYS  closed  before  it  is  removed!  If  the  mouthpiece  is 
removed  in  the  water  at  the  surface  and  it  is  left  open,  the  water  pressure  will 
immediately force all the gas from the counterlungs out, as a result of which the diver 
will lose buoyancy and may sink.  
*  Once  on  dry  land:  remove  the  mouthpiece,  close  the  valves  of  the  cylinders,  and 
take the rebreather off your back. 
  
4.5: Maintenance between several dives on the same day: 
 
* Remove the breathing hose assembly  and rinse it with cold  or lukewarm water: to 
do  this,  close  the  mouthpiece  and  pour  water  into  the  inhale  side  (black  connector). 
Let  the  water  leak  out.  Never  use  high  pressure  or very  hot  water:  this  will  damage 
the ' mushroom-valves' or membranes in the mouthpiece.  
* If the scubbers are not at their end still can give some output, take both scrubbers 
out of the rebreather and put them in a double plastic bag or an airtight container.  
*  Rinse  the  moisture-absorber  with  fresh  water,  squeeze  all  the  water  out  and  let  it 
dry, leave the rebreather open to dry, either standing up or laying on its front with the 
lid  side  up,  (place  the  carrying  frame  of  the  cells  out  of  the  inhale  lung,  so  that  the 
inhale lung can dry out too).  
* Clearly write down your used scrubber time. 
  
 
4.6: Maintenance at the end of the day: 
 
* Close the valves of the cylinders.  
*  Pay  attention  that  the  rebreather  is  completely  closed,  including  the  mouthpiece, 
and rinse the rebreather thoroughly on the outside with fresh water. Inflate the wing 
by half. Pay attention to rinse all components, the regulators and the inflator buttons. 
It  is  also  adviced  to  push  the  manual  addition  buttons  for  oxygen  and  diluent  a  few 
times  while  spraying  water  on  them,  in  order  to  remove  any  salt  and  dirt  that  may 
have accumulated.  
* Turn the rebreather flat on its front and remove the cover: in order not to lose the 
fixing screw, put it back on the wire grip!  
* If you still have remaingin scrubber time, take both scrubbers out of the rebreather 
and  put  them  in  a  double  plastic  bag  or  an  airtight  container.  Never  store  the 
scrubbers  in  a  warm  place  or  in  direct  sunlight,  they  may  dry  out  completely  and 
become unusable.  
*  Take  both  the  cell  mounting  and  ADV-fixing  out  of  the  scrubber  holders  and  lay 
them aside, on the cylinders. Remove the moister-pads, squeeze them and rinse them 
in fresh water. Pour fresh water in both of the lungs of the rebreather and shake the 
rebreather  a  number  of  times,  (the  breathing  hose  is  still  connected  and  the 
mouthpiece is closed). Leave the water for 5 minutes  in the rebreather, then pour it 
out, by removing the breathing hose and inclining the rebreather top-down so that the 
water flows out. Now let the lungs dry. Do not stock the rebreather in direct sunlight 
for longer periods: this can shorten the lifetime of some of its components. 
 
*  Rinse  the  breathing  hose  assembly  with  cold  or  lukewarm  water:  close  the 
mouthpiece and pour water into the inhale side. Let the water leak out. 
*  It  is  recommended  to  disinfect  the  rebreather  (both  the  lungs  and  the  breathing 
hose) after 5 consequetive diving days. To do so, only use a product that is allowed at
