After leaving the oxygen flow meter, oxygen is directed through
plastic tubing to this port in the partition wall between the electron-
ics compartment and the filter/fans compartment (Figures 23, 29,
and 30). The oxygen is released into the airflow after the air passes
through the Sodalime filter, and is then carried to the animal com-
partment in the circulating air. Also, refer to Figure 23.
The temperature sensor (Figures 29 and 30) senses the temperature
of the circulating air after it passes through the chiller and heater.
This data is compared to the temperature called for on the tempera-
ture set dial and the result causes the heating or cooling systems to
turn on or off as needed.

The heater (Figures 29 and 31) applies heat to the circulating air as
it passes through the filter/fans compartment. It acts in response to
the setting on the temperature set dial as compared to the level of
heat in the animal compartment detected by the temperature sensor.
A metal mesh filter in the filter/fans compartment (Figure 29 and 32)
cleans air returning to the compartment from the animal compart-
ment. Its purpose is to remove animal hair and other contaminants
from the circulating air before it passes through the Sodalime filter.
For instructions on cleaning the filter, refer to Cleaning the Filter/
Fans Compartment Filter on Page 67.
