CHECK the integrity of the probe after having removed it from the box.
Check that the data written on the box correspond to the type of gas used.
When doing the electrical connections, follow the drawing closely.
Any use of the detector for purposes other than the intended one is considered improper, and as a
result of which BEINAT S.r.l.  therefore disclaims any responsibility for possible damages caused to
people, animals or objects.

IMPORTANT:  The  operation  test  should  not  be  carried  out  with  the  gas  tap  as  this  does  not  guarantee
a  sufficient  concentration  to  activate  the  general  alarm.

TERMS and EXPECTATIONS: The installation of the BX444-Mc probe, its ordinary and extraordinary maintenance,
and its out of service removal at the end of the functional life guaranteed by the manufacturer, must be carried out
by authorized and/or specialized personnel.
Do not allow it to become wet.
The probe can be seriously damaged when immersed in water. Remember that the probe has a protection degree IP44.
Do not drop it.
Heavy knocks or falls during transportation or installation can damage the appliance.
Avoid abrupt temperature fluctuations.
Sudden temperature variations can cause condensation and the probe could work poorly.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.
Absolutely avoid using any cloth dipped in thinners, alcohol and chemical detergents.

WARNING!  Actions  to  be  taken  in  case  of  alarm

G a s
1)  P
ut  out  all  free  flames.
2)  Close  the  main  gas  tap  or  the  LPG  cylinder  tap.
3)  Do  not  turn  any  lights  on  or  off;  do  not  turn  on  any  electrical  device  or  appliance.
4)  Open  windows  and  doors  in  order  to  increase  ventilation.
If  the  alarm  stops,  its  cause  must  be  found  and  the  relevant  consequent  measures  taken.
If  the  alarm  continues  and  the  cause  of  gas  presence  cannot  be  found  or  removed,  abandon  the  building
and  call  the  emergency  services  when  outside  (fire  department,  distributors,  etc.)

IMPORTANT: The operation test should not be carried out with the gas tap as this does not guarantee a sufficient concentration
to  activate  the  general  alarm.

Warning  !!

If  you  have  the  following  symptoms:  vomiting,  sleepiness,  or  else,  go  to  the  closest  first  aid
station  and  inform  the  operators  that  you  could  have  been  poisoned  by  Carbon  Monoxide

or

by an excess or deficiency of oxygen

MAINTENANCE
The  user  periodically  (every  6  months)  must  perform  a  check  of  the  operation  of  the
control  unit  by  spraying  a  suitable  test  gas  at  the  base  of  the  probes  connected  until  the
alarm  condition  is  reached.
•  At  least  once  a  year  make  a  more  accurate  check  by  a  specialist  technician.
•  Disabling  the  detector  must  be  carried  out  by  qualified  personnel.
