THEORY OF OPERATION
The Fluido DHT utilizes ambient air and pressurizes it via an internal blower. The pressurized air is directed across a heating
element bringing the media to the desired treatment temperature. The heated, pressurized air is then diffused across and
through a baffle to fluidize and heat the Cellex media in a patient treatment reservoir. All treatment parameters; air speed,
temperature, treatment time and the unit preheat settings are programmed by the operator with the touch panel user interface.
The Fluido DHT unit base incorporates four locking casters and a manually operated hydraulic lift to adjust height and rotation
of the treatment reservoir for patient comfort.

VERIFYING TEMPERATURE CALIBRATION
After each change of Cellex media, perform a temperature
check to ensure that calibration of unit has not changed.
The temperature displayed on the display is an average of
the temperature throughout the media chamber. Because the

Fluido DHT System Testing
General
The following information is intended to aid in
troubleshooting the major components of the DHT Units
to “Board Level” only. These tests are OEM standard
testing procedures and methods used at the factory before
shipment of any Fluido unit.
Due to the complex nature of the technology utilized by
Chattanooga Group, the recommended troubleshooting
techniques are to determine “Bad Board” and
board replacement only. No board component level
troubleshooting is recommended nor will information
or parts be supplied by Chattanooga Group. Any board
component level troubleshooting performed will be at sole
risk and liability of the Service Technician performing such
troubleshooting techniques.
Once the PC Board has been determined as bad, replace the
board only with Chattanooga Group OEM replacement parts
and hardware.
Special Tools, Fixtures & Materials Required
Certain tests require the use of special tools and fixtures.
These will be listed at the particular test where they are
required. Testing with any other special tool or fixture
other than those stated could give erroneous readings or
test results. Always perform the tests exactly as stated to
ensure accurate results.
Standard test equipment settings will be listed for each test
performed to aid in performing the test to OEM standards
and ensure proper readings.
The troubleshooting and repair of the Fluido DHT units,
should be performed only by authorized technicians trained
and certified by Chattanooga Group.

VERIFYING TEMPERATURE CALIBRATION
After each change of Cellex media, perform a temperature
check to ensure that calibration of unit has not changed.
The temperature displayed on the display is an average of
the temperature throughout the media chamber. Because the
media is fluidized by the movement of forced air, there are
zones throughout the chamber. The temperatures measured in
each zone may vary by ± 8° F or ± -13°C.
Once the Cellex has been changed and operated at 50% for
1 hour, turn off the unit and immediately remove the lid to
the unit. With a calibrated thermometer, take a temperature
reading in the following zones – approximately half way down
from the top of the media.
Calculate the average temperature by adding all five readings
together and dividing by 5. The resultant number should reflect
the set temperature ± 2° F or ± -17°C.
