GENERAL
The BS-375/WP/A and BS-376/WP/A explosive
gas detectors are used to measure the
concentrations in % L.E.L. (Lower Explosive
L e v e l ) w h i l e s i m u l t a n e o u s l y p r o v i d i n g
autonomous notification/alarm operations in
case there is a leak of liquid on natural gas.
They are used in commercial and small
industrial areas such as professional kitchens
and burner rooms.
The installation must be done by trained
p e r s o n n e l t h a t h a s p r e v i o u s l y r e a d t h e
instruction manual.
In case on an alarm or gas leak:

independent of their order.
-
Turn off all burning flames and anything that is
smoking.
-
Close all gas appliances
(
kitchens
-
burners
cookers
etc
.)
- Close the central gas supply or canister.
- Open doors and windows in order to ventilate
the area.
Avoid
:

(*) =
(
Ideal conditions
)
When the detector is exposed to
cleaning agents, silicons and generally
in commercial and light industrial environments
, it is recommended to be calibrated every year
and
its sensor to be replaced every 3 years!
ATTENTION!! DO NOT USE LIQUID
GAS
(i.e. lighter
gas
) FOR SENSOR
TESTING
BECAUSE
IT
CAUSES PERMANENT DAMAGE. Use calibration gas up to 50% L.E.L. for this purpose.
(**) = does not cover the gas sensor, if it is exposed to Si, H2S, Pb & halogenated hydrocarbon.
