4. Cleaning
The ICU must be empty at the time of cleaning. Cleaning is feasible only after removal.
5. Maintenance
It is suggested to maintain the machine every two months during normal operation, which shall be
carried out in accordance with removal, installation and maintenance procedures above.
After the power switch is pressed,
there is no reaction or the power
indicator lamp is still off
Phenomenon
16 17
1.Bad power connection and
plug connection
2.Damaged switch
Cause analysis Solution
1. Check power connection
2.Replace the power switch
Little atomizing volume form
the medical atomizer
1.Too big atmizing particles of
solution causes little atomizing
volume
2.Solution contains syrup or
colloform
3.Tablets are used for
dissolution
4.Oily impurities on the surface
of solution
1.Too big particles are not
suitable for operation of this
atomizer
2.When solution contains
syrup or colloform,it requires
with dry filter paper
3.When tablets are used for
dissolution,dissolve sediments
to remove impurites first
4.Remove oily impurities on
the surface of solution with
clean tissue firstivvv
No atomizing from the atomizer
1.Water shortage of the water
tank the atomizer
2.Damaged ultrasonic chip of
the atomizer
3.Water scale in the tank of the
atomizer
1.Add water into the water
tank until it is at the same
level of the cup bottom
2.Replace the ultrasonic chip
3.Gently scrub the inside of
the tank with lint
Remaining solution not
atomized in the cup after
atomization of the medical
atomizer
Atomizing time and volume
depend on concentration of
atomizing liquid
Repeat the atomization
operation procedure if not
completely atomized once
The humidity is not increased
after raising the set point of
humidity
1.Water shortage in the bottle
of the humidifier
2.Damaged chip of the
humidifier
3.Water scale in the metal
water level sensor inside the
humidifier tank
1.Add water into the bottle
2.Replace the humidifier
3.Remove water scale inside
according to the chapter of
“separate cleaning of the
humidifier”, or try to dip some
vinegar into the water bottle of
the humidifier
