DESCRIPTION OF DEVICE
The AquaTREND uni is a plug-in hot air humidifier for
the TREND II respiratory therapy device or TREND-
vent ventilator.
It is used to add humidity to the therapy air flow to pre-
vent the mucous membranes in the upper respiratory
passages from drying out.
The heating power can be set to 5 different levels and
can thus be adjusted to the patent's individual require-
ments.

USING THE HUMIDIFIER
Before using for the first time, rinse the humidi-
fier thoroughly with clear water. To do this, read
section "Cleaning" on page 24.
While it is being filled, the humidifier must not
be attached to the respiratory therapy device or
ventilator.
When the humidifier is full of water, it must not
be laid on its side or turned over because water
could leak.
Using the blower when the humidifier is full and
not connected to the tube system may lead to
drops of water being carried along by the air flow.
Therefore, only use the humidifier when the tube
system is properly attached.
16 Using the Humidifier

FILLING THE HUMIDIFIER
1. Open the humidifier by twisting the sealing cap
anticlockwise off the water container.
2. Only fill the humidifier with cold, decalcified, boiled
water containing no additives. Alternatively, you

Note the specified maximum fill level.
3. Close the water container by placing the sealing
cap on the container with slightly pressure and
turning it clockwise until it stops.
While carrying the filled humidifier please keep hold
of the reservoir.
