8 Technical Description
TECHNICAL DESCRIPTION
The device is a warm air humidifier which can be mounted
on devices of the respiration therapy line TREND II.
It is intended to humidify the therapy air flow with mois-
ture to prevent the mucous membranes of the upper
respiratory tract from becoming dry.
The heater output can be adjusted in five levels thus
allowing the device to be adjusted to the individual
patient’s requirements.
When turning off the therapy device or taking off the
humidifier the device saves the heating level that was
set last.

10 Operation of the Device
OPERATION OF THE DEVICE
Rinse the humidifier thoroughly with clean fresh water
prior to its first use.
Do this as described in the chapter “Cleaning” from
page 13.
When filling the humidifier it must be disconnected from
the therapy device.
Open the humidifier by turning the cap in anti-clock-
wise direction and removing it from the water reservoir
(see illustration on page 13).
Fill the humidifier with cold distilled water for medical
applications or boiled cold water with a low lime in con-
tact. The water must be cold and contain no additives.
Fill in the water only up to the specified maximum fill-
ing level.
Close the water reservoir again by placing the cap onto
the water reservoir with slightly pressure and turning it
in clockwise direction until it stops.
While carrying the filled humidifier please keep hold
of the reservoir.
Operation of the Device 11
Never tilt or turn over the humidifier after filling it. When
connecting the humidifier with your respiration therapy
device please observe the following instructions:
•
Place the contact pins and air inlet of the humidifier
on the therapy device without twisting or canting
them.
•The release button has to snap in place audibly.
12 Operation of the Device
The heating power can be set to five levels at the ther-
apy device.
For starting operation of the humidifier push the heater
key on the TREND II device. The display now shows
the currently set heating level and the heater LED lights.
After starting the operation of the device with the control
key the heating level will be continuously be displayed.
If you interrupt or end the therapy with the control key
the heater LED will flash and the humidifier is set to
standby.
For changing the heating level press down the heater
key for approx. 1 second until the heater menu is dis-
played. By pressing the key the heating level can be
selected. You can now set the heating level with the
help of the key and (higher level = higher tem-
perature). Confirm by pressing .
CAUTION!
Operating the blower when the humidifier is filled
but the therapy tube is disconnected may cause
water droplets to be swept along in the air flow.
Therefore the therapy tube should always be firmly
in place before switching on the humidifier.

Cleaning 13
CLEANING
Please carefully follow the hygiene and cleaning instruc-
tions in order to preserve your health and to avoid dis-
turbances and failures.
Except from cleaning it regularly, the device requires
no further maintenance.
The regular, daily cleaning prevents the built-up of lim-
escale which is difficult to remove.
Press the release button, separate the humidifier from
the therapy device, and take the humidifier to a sink.
Open the humidifier by turning the cap anti-clockwise
and removing it from the water reservoirs (1).
ATTENTION!
Never use sharp or pointed objects for cleaning
the humidifier.
Empty the water reservoir and rinse it with running
water(2). Remove any limescale by wiping it with a
soft cloth (3).
If tough limescale has built up we recommend using
normal limescale remover or filling the water reservoir
with a thin vinegar solution and let it soak for a while.
Then empty the reservoir, wipe off any residue limes-
cale with a soft cloth and then rinse the reservoir thor-

14 Cleaning
oughly under running water.
Before cleaning the cap remove the air guide as shown
(4). It is sufficient to rinse the device daily with run-
ning water.
It is important to let the humidifier dry completely after
cleaning it. Do not refill it before it has not dried out
completely. You can also clean the water reservoir and
the cap in the dishwasher at a temperature of up to
60 °C. However, we recommend thoroughly rinsing it
with running water to avoid deposition of food leftovers
from the dishwasher.
A chemical or heat disinfection of the humidifier by the
user is not required and is not recommended.
AquaTREND uni is intended for use by only one patient.
Before using it for another patient it has to be profes-
sionally sanitized. Please take the humidifier to your
specialized dealer to have it sanitized.
