Remove the communication cable from the ozone generator.

Remove the 2 hoses from the ozone generator: "O

connection is color-coded.
}
Remove both angled FAST connectors from the ozone generator.
}
Remove the screw the ozone generator is fastened to the base plate with (see ar-

}
Carefully push the old ozone generator out of the module and remove it. Insert a new
ozone generator in the detection module. Mount the ozone generator in reverse or-

Connect the detection module to the basic module.
}
Switch on both modules and allow them to run in for approx. 30 min.
}
Wet a strip of the indicator paper with distilled water and hold it to the ventilator on
the rear of the module for approx. 30 s.
}
Also check the gas outlet of the detection modules with the test strip.

If the strip turns blue, ozone is leaking from the module. If this is the case, switch off
the module, ventilate the room and check the proper connection of the hoses on the
ozone generator.
