to ventilate potentially contaminated space.
AMBIENT CONDITIONS FOR INSTALLATION
PROCEDURE IN CASE OF MALFUNCTION
Device has to be installed in the place where it is protected from rain, water sparkles, with temperature
correspondent to its climate class (marked on label Technical data); in case this terms are not assured
warranty is no longer valid and malfunctions in performance are possible.
Possible climate classes are:
SN – temperature of environment from 10°C to 32°C
N – temperature of environment from 16°C to 32°C
ST – temperature of environment from 18°C to 38°C
T – temperature of environment from 18°C to 43°C

WORKING PRINCIPLE
CO2 is passing through the pressure regulator and going into CO2 IN connection, then through non
return valve (2) into carbonator (3).
Water is going from water line to WATER IN connection, passing through pump and non return valve
into carbonator (3).
In carbonator (1) CO2 apsorbs into water. Soda water is going out trough SODA WATER OUT
connection.
