6

Cautions

1.Installation must be vertically.

2.Organic solvents(including sillica gel and other adhesive),paint,pharmaceutical,oil and high

concentration of target gases should be avoided.

3.Artificial air steam such as fan should be farm away.For example,when it is used in air refresher,it

can’t be installed in front or back of fan.Any side of fan shell can be installed on, but ventilation

opening on the shell is necessary to guarantee gas from outside flow in.

4.Don’t use it the places where there is vapour such as bathroom,or near to air humidifier.

5.Dust sensor adopts optics working principle,so the light radiation will influence the sensor’s

accuracy.We suggest users use sponge to cover the triangle hole in the middle of the

sensor,avoiding light outside irradiate the sensor.Note that don’t cover the gas inlet and outlet.

6.Warmup time should lasts 5 min or longer for the first time usage and don’t apply it in the

system involving people safety.

7.Moist will effect the normal functions of the module,so it should avoid.

8.Lens should be cleaned regularly according to the actual condition(about once per month).Use

one end of cotton swab with clean water to scrub the lens,and use the other end to wipe dry.Don’t

use organic solvent such as alcohol as cleanser.
