4 Note on operation
The treatment unit should be inspected and its proper function
checked daily prior to being used with patients (tubes, cable
connectors, display instruments, cleanliness, etc.)
Power and water connections for the treatment
unit must be secure.
Note for units with a glass display: the unit is operated using a
touch-sensitive glass surface, which covers a set of sensors. The
sensors transform touches of the sensor field into a switching
signal. The sensors react to touch with a short delay (in order to
avoid unintended touches) and activate the relevant function.
Activation of a function is signalled with a click. After activating a
function, the colour of the sensor field changes from blue to green.
It remains blue for as long as the function remains active.
Fig. 1: Glass display
4.1 Main power switch
The treatment unit is switched on via the main power switch (fig.
2) and is then ready to use.
Models with glass display only: on the Europa and Paris models,
the main power switch is located on the rear of the control panel.
Pressing the main power switch places the unit in stand-by mode.
To switch the unit into ready mode, touch the on button (fig. 3) for
3 seconds. The unit is then ready to use. The illuminated green
buttons indicate that the unit is ready to use. Only those buttons
which can be activated will be illuminated (i.e. only those options
which have been ordered).
To switch the unit back into stand-by mode, touch the on button
for 3 seconds. The buttons will cease to be illuminated and the on
button will be colored blue.

4.2 Mirror heater
Pressing the button (fig. 4) causes warm air to flow from the
opening. The mirror is heater at a distance of 3 - 4 cm from this
opening. The mirror heater remains active for about 16 seconds
before switching itself off automatically. In order to avoid a build
up of heat within the casing, the fan continues to run for a further
10 seconds.
Should an excess temperature be detected, a safety thermostat
will deactivate the mirror warmer.
Caution! Do not place any objects or body parts
directly over the opening, as the metal grid can
become very hot.
Fig. 4: Glass display
4.3 Suction with manual emptying (option)
Suction is activated automatically when the suction tube is
removed.
Caution! Please use suitable suction catheters for
suctioning and regulate the volume of flow to
prevent any risk of injury as a result of excessive
pressure focused at a single point.
The end of the suction tube has an adaptor for either an ear
rinsing bowl or a suction cannula (you have to change the
suction cannula after each patient!). After completing treatment,
the vacuum pump deactivates automatically when the suction tube
is replaced in the suction tube holder (the 3rd holder form the left
on the swivel arm). Patient secretions are suctioned into a
dedicated reservoir which is located behind the side hatch, where
they are collected until the reservoir is full.
For reasons of hygiene, this reservoir should be emptied daily.
The reservoir will otherwise continue to fill until the overflow
prevention mechanism is triggered. A red warning light on the
control panel indicates that the reservoir is full. The reservoir must
be emptied when this warning light is illuminated.

Optional manual suction pressure control, allowing the required
suction pressure to be controlled using a control knob or an
adapted “Fingertip”(fig. 7), can be ordered separately.
Caution! The contents of the suction reservoir
may be contaminated.
Fig. 7: Fingertip
4.4 Suction with „Sekretomatik“system (option)
Suction is activated automatically when the suction tube is
removed.
Caution! Please use suitable suction catheters for
suctioning and regulate the volume of flow to
prevent any risk of injury as a result of excessive
pressure focused at a single point.
The end of the suction tube has an adaptor for either an ear
rinsing bowl or a suction cannula (you have to change the
suction cannula after each patient!). After completing treatment,
the vacuum pump is deactivated automatically when the suction
tube is replaced in the suction tube holder (the 3rd holder form the
left on the swivel arm).
The “Sekretomatik”system is activated automatically when the
suction tube is replaced in its holder. This empties the contents of
the suction reservoir into the drainage system. After emptying, the
suction reservoir is rinsed. A small volume of water is left in the
reservoir to prevent adhesion of secretions.
Optional manual suction pressure control, allowing the required
suction pressure to be controlled using a control knob or an
adapted “Fingertip” (fig. 7), can be ordered separately.

4.5 Cold light sources (option)
The light sources are activated by cold light source buttons 1 to 4
(fig. 10 buttons 1 to 4). Only one light source can be active at any
one time –an automatic electronic system prevents more than
one light source from being activated simultaneously. The light
extinguishes automatically after 15 minutes.
If you intend to leave the device switched on for a prolonged
period (30 minutes), hold down the light button for 2 seconds
when turning the device on (operation mode). Only one light
source can be activated at any one time. An automatic electronic
system prevents multiple light sources from being activated
simultaneously. If a cold light headlight is used, the cold light
source will switch on when the headlight is removed from its
holder. This cold light source can also be switched on from the
control panel as a ‘normal’ cold light source using the
corresponding button, should you subsequently prefer an
alternative use. This requires the headlight holder to remain
actuated or the jack to be removed in order to deactivate the
holder.
All treatment units are equipped with removable STORZ-type light
outputs as standard. Other outputs can be supplied on request.
An adaptor at the end of the optical cable can be used to connect
lenses or endoscopes. Please ensure that you use the correct
adaptor.
Units built after July 2010 can also be equipped with LED cold
light sources. The LEDs are switched on and off using the same
buttons. LED cold light sources have a brightness control next to
the light outputs on the side hatch as standard.
Note! Save energy by only activating the cold
light source when it is really needed. This also
extends the life of the lamps.
Caution! Never direct the light beam directly into
the eyes!

4.6 Compressed air unit (option)
The compressor is activated when the unit is switched on. It
compresses air into a compressed air reservoir until the fixed or
required pressure is achieved. The air pressure (in bar) is
displayed on a right manometer (fig. 14). The delivered pressure
can be adjusted using the lever on the compressed air sprayer. If
the lever is depressed with more force, more air is discharged
from the air outlet. An optional continuously variable control knob
allows air pressure to be adjusted within the range 0.2 to 2,5 bar
(required for “Politzer”-application or for application of children!).
The unit is able to generate a maximum pressure of 2,5 bar.
The medicament sprayers are included with the unit, (optional)
Politzer olive or other devices can be attached to the front end of
the compressed air sprayer (fig. 16).
Caution! Politzerisation may only be performed
on units with an optional compressed air
regulator and at a maximum pressure of 0.5 bar.
Please check the pressure gauge and that the
unit is functioning correctly beforehand.

4.7 Ear irrigation with water connection (option)
The hot water irrigation system is primarily used for ear irrigation.
The hot water irrigation system is activated by actuating the water
irrigation button. A temperature indicator continuously displays the
set and actual water temperatures. The top temperature is the
actual temperature, the bottom temperature the factory-set target
temperature (37° C).
An electronic safety system prevents the water temperature from
rising and deactivates the water system if the temperature
reaches 45° C.
Caution! Check the water temperature before
using the ear irrigation system. Check the
temperature display and run some water over the
back of your hand if necessary.

4.8 Ear irrigation with autonomous water system
(option)
Treatment units equipped with an internal water system are
supplied with water via a 5 liter tank installed behind the unit. The
water is heated by a water heating system.
Caution! Before working with the water irrigation,
ensure that there is enough water in the tank (the
tank should ideally be full).
The hot water irrigation system is activated by actuating the button
(fig. 20). The water heater temperature is factory-set to 37° C. A
thermostat and an additional safety system (activated at 45° C)
provide redundant protection against excess temperatures.
Note! The irrigation system should be deactivated
when not in use. This saves energy and extends
the lifespan of the pump.
Caution! The water jet must not be directed
directly at the eardrum.

In order to prevent accumulation of secretions and consequent
blockages in the suction system, we recommend using the
optional tube rinsing system.
The tube rinsing system is activated when the suction tube is
pressed onto the tube rinsing nozzle with the silicone tube
(important!) attached. The automatic tube rinsing system starts
after 0.5 s and continues for 3 s. (an error will be registered if the
rinsing nozzle is activated before the suction unit. The ‘Suction
reservoir full’ light on the control panel will flash alternately red
and green. The tube rinsing system will in this case be
deactivated). This can be repeated, but should not be repeated
more than three times, as the collecting reservoir will quickly
become full.
Note: We recommend using the tube rinsing
system at least daily.
Fig. 23: Tube rinsing
4.10 Tube rinsing system with disinfectant
(option)
In addition to the standard tube rinsing system (using water), it is
also possible to install a disinfectant container for a disinfectant
rinse. The tube rinsing system is activated when the suction tube
is pressed onto the tube rinse nozzle with the silicone tube
(important!) attached. The automatic tube rinsing system starts
after 0.5 s. The suction tube is rinsed alternately with water and
disinfectant (from the disinfectant container) for 5 s. (an error will
be registered if the rinsing nozzle is activated before the suction
unit. The ‘Suction reservoir full’ light on the control panel will flash

5 Maintenance and repair
The treatment unit should be serviced annually.
5.1 Cleaning
Caution! Switch off at the main power switch and unplug the unit from the mains
before cleaning or disinfecting. To check that the unit is not under electrical tension,
turn it on at the main power switch.
Caution! Apply cleaning or disinfectant liquids with a soft cloth, do not pour directly
onto the casing. Extra care is required when using flammable liquids. Do not allow
any liquid to run into the device.
Clean the surface of the MODULA Duo using a soft cloth soaked in a non-aggressive cleaning agent or
disinfectant. Do not use ammonia-containing (e.g. Sidolin) or abrasive cleaning agents, as they will
destroy the painted surface over time. All-purpose cleaners and ethanol are particularly suitable as
cleaning agents. Components should always be subjected to a visual inspection after cleaning, with
particular attention paid to cracks, breaks and mechanical failure. Do not use alcohol-containing cleaning
agents when cleaning the perspex cover.
Note! Please clean the suction tubing at least daily using the optional integrated tube
rinsing system (option).
If your unit is not equipped with an integrated tube rinsing system, take a container containing a non-
foaming disinfectant solution and clean and disinfect the suction system by suctioning this solution up.
The suction reservoir (for manual suctioning) should be cleaned whenever the device is serviced (six
monthly). To do so, open the left side hatch, remove the suction reservoir and clean thoroughly. The
reservoir is resistant to disinfectants.
Never operate the treatment unit without the suction reservoir.
Note! Remember that normal cleaning of treatment surfaces achieves a 50 to 80%
reduction in the number of microorganisms. Effective disinfection achieves a
statistically significant reduction of at least 84 to 99.9%. (Source: RKI)
When using disinfectants, always follow the manufacturer’s instructions with regard to concentration and
how long to leave the disinfectant to take effect.

G. Heinemann Medizintechnik GmbH
MODULA Duo

User`s manual MODULA Duo (HM_TK_GA-Duo_28062013_08_EN)
Caution! Following disinfection, the components of the nebuliser, water jet and
silicone tubing should be rinsed until free of residues.
As with other instruments, all auxiliary devices and associated instruments (e.g. ear irrigation cannulae,
instrument trays, dishes for discarded instruments, etc.) should be regularly sterilised or disinfected. This
includes water jet cannulae, the nebuliser drug vial nebulisers and the silicone suction tubing.
5.2 Changing the bacteria filter
For hygiene reasons, the suction system outlet is fitted with a
bacteria filter. This is located at the rear of the left side of the unit.
Caution! Please dispose of contaminated waste
correctly.
To change the filter, disconnect the two silicone hoses from the filter
and then connect the hoses with the new filter. The flow direction is
not important.
Caution! Use gloves, the filter may be contaminated.
It is recommended to change the filter once a year or as needed.

5.4 Replacing the waste bag
For hygiene reasons, check the waste bag at the end of every day and dispose of it if it is even part full.
Caution! Pay attention to the proper disposal of contaminated waste!
5.5 Optical cable
If your unit has one or more cold light sources, a range of lenses can be attached to the cold light adaptor
via an optical cable. The light adaptors have a STORZ connector. Optional detachable light outputs for
connecting Storz, Wolf, Olympus and Pentax connectors are available. The optical cable is simply
inserted or removed. No additional tools are required.
Fig. 30: Control panel with cold light sources
There is a pre-set locking screw beneath the cable connector. This can also be used to adjust the force
with which the locking screw secures the cable. To fix the optical cable more tightly in the connector,
carefully tighten the screw and check the force required. To fix the optical cable less tightly, carefully
loosen the screw. A range of optional optical cable adaptors (Wolf, Storz, Olympus, etc.) can be ordered
separately.
5.6 Replacing the halogen lamp
Caution! Always switch off at the main power switch before replacing the halogen
lamp. Unplug the treatment unit at the mains. To check that the unit is not under
electrical tension, turn it on at the main power switch.
