Trouble-shooting
3. Complete Cleaning and Maintenance: remove and clean parts and assemblies periodically. Desired
results are achieved only by cleaning after removal.
Steps for Disassembling Components:
Remove four screws from the master control rack on the right to take down the right master control rack,
(remove the left master control rack in the same way). See figure. 8.3.1.
Remove power connection plugs on power cords on one side of the master control rack one by one. Note
that plugs have different colors for each electrical component.
Warning: do not remove control racks or electrical components from control racks immediately after shut
down; give it some time to cool down. The heaters in control racks reach high temperature. Remove control
racks or contact heaters after a 30 minutes respite after shutdown.
Remove and clean filters behind the square plastic section inside the chamber.
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.

No atomizing form the
atomizer
1.Water shortage of the
water tank of the atomizer
2.Damaged ultrasnic chip of
the atomizer
3.Water scale in the tank of
the atomizer
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
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
After the power switch is pressed,
there is no reaction or the power
indicator lamp is still off
Phenomenon
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

Remove four screws in the fan box and take out the whole heater. Clean the fan. Try not to remove heat sinks
from the fan, especially PTC heater bands that cannot be removed from heat sinks. See figure. 8.3.2.
