Cleaning and Maintenance
Alarm and Processing Control: when the CO
2
concentration is higher than the set point and remains
constant for some time (to avoid false alarm for an abrupt increase of partial concentration), the CO
2
Concentration Indicator Lamp is flashing with the alarm. Start both the left fan and the right fan to enhance
ventilation inside and outside. If the CO
2
concentration remains unchanged, open the ICU door to enhance
ventilation. When the CO
2
concentration is equal to or lower than the set point, switch off the CO
2
indicator
lamp and close the alarm. If fans are not needed when other functions are working the fans automatically
stop.
CO
2
Concentration Control: the default factory setting is 1000PPM-1000 in a million (0.10%). PPM=solute
mass/solution mass*1000000. Reference set point: the CO
2
concentration of 0.1% is harmful to animals;
the CO
2
concentration of 0.5% causes loss of breath and dizziness; the CO
2
concentration of 1% makes it
increasingly difficult for animals to breath, gradually fading to a fatal point.
CO
2
concentration in air: 0.030% -- 0.039% (oxygen concentration: 20.95%).
1. Disinfection & Sterilization: after incubation or caring of one pet finishes treatment and care, it is
suggested to disinfect and sterilize this machine. Do this once every week when not in use. It’s important
to maintain clean equipment.
2. Cleaning of the Humidifier (Old version): if the Humidifier falls to atomize, or the water spills out, take the
following measures:
a) Open the cover plate of the right Control Rack.
b) Remove the water tank of the humidifier. (Remember to disconnect the plug on the water tank
beforehand).
c) Brush off the mineral substance such as water scale or verdigris on the Water Level Sensors (the three
copper inserts on the inner surface of the water tank).
d) Place the water tank back, insert the connection plug, and secure the cover plate.
e) Brush off minerals on the inner water level sensor (the only slim metal column inside the humidifier
chamber) and the bottom vibrator (water scale) by sticking a brush into the atomizing inlet.
f) Cover the humidifier pipe.
g) Cover the inner cover plate. Make sure the rubber at the pipe outlet covers two feet at the bottom of the
cover plate. Installation tip: push the cover plate from top to bottom and then from outside to inside. Install
screws into the cover plate.
Press "SET" key to remove disengage alarms. See figure. 7.11.1.

Cleaning of the Humidifier (New version): if the Humidifier falls to atomize, or the water spills out,
take the following measures:
a) As shown In Figure 8.3.3-a, Open the cover plate of the Water Vessel of the humidifier (on the
control rack).
b) As shown In Figure 8.3.3-b remove Humidifier from the Water Vessel and as shown In Figure
8.3.3-c, remove Water Level Sensors.
c) Take out the Water Vessel of the humidifier as shown In Figure 8.3.3-d.
