4.0 Operation

Before switching on the unit, make sure that the handle is in
its holder (jet must point to reverse side of the unit).

4.1 Selecting temperature level

• After operating the main power switch, the automatic
activation of the thermal process begins for reducing
bacterial count, followed by the automatic activation of
the temperature level "irrigation mode" (37 °C).

4.2 Description of operating modes

4.2.1 Thermal process for reducing bacterial
count
Purpose:
Reduction of bacteria count in the warm water circuit to
prevent or clear a contaminated system.
Activation:
Occurs each time the unit is switched on.
• Condition for starting the correct thermal process for
reducing bacterial count:
- The irrigation handle must be inserted in the holder
on the side (jet pointing to reverse side of the unit).
ª If not, a warning signal is given (warning also sounds
when the handle is removed during the thermal clean-
ing procedure).
ª Additionally, the error code "F0" is shown (disappears
when handle is returned).
) In the thermal process for reducing bacterial count hot
water is being ducted through the irrigation handle.
Please do not take the handle from its holder or spray
water!
) Metal parts of the irrigation handle and of the double-bar-
relled hose will be hot! Please do not touch metal parts
during the thermal cleaning procedure!
• During the thermal process for reducing bacterial count,
the temperature display shows a 'd' on the first segment
and the remaining time (in minutes) on the second seg-
ment.
• After cooling down to 37 °C, the unit will automatically
switch to irrigation mode.

4.2.2 Irrigation mode

Purpose:
Rinsing of the auditory canal.
Properties:
• Temperature: 37 °C, permanently set.
• Water flow: at least 400 ml/min, after turning open the
limiter screw on the release lever of the handle (, Fig.
4).
Activation:
• Automatically after completion of thermal cleaning proce-
dure and taking out the handle.
• When the irrigation mode is not being used (handle
remains in holder), the Hygrotherm plus changes into
energy saving mode after 5 min.
• Reactivation of the irrigation mode by taking the handle
out of the holder or activating a key on the temperature
control unit.

4.2.3 Energy saving mode

Purpose:
Reduction of energy consumption.
Activation:
• Activation of key "heating on/off" (, Fig. 1).
ª Heating is switched off.
• After five minutes of non-use of the unit.
