Intended use / For your safety
■ Intended use
Bathing system for bathing patients with restricted mobility in
care institutes and hospital wards. It is operated by healthcare
professionals. The possible height adjustment provides an ergo-
nomic working environment for the personnel and helps keeping
their spines healthy.
■ For your safety
 Ensure that this bathing system is operated and maintained
only by trained personnel.
 Always check the water temperature with your bare hand (also
when using the shower) before bringing the water in contact
with the patient.
 Ensure that each client is assessed for its ambulatory capa-
bility, ensuring the client’s safety when entering and exiting
the bathing system (utilize handgrips, correct entry height,
correct client transferring device, etc.).
 Never leave the patient unattended inside the bathtub.
 Ensure that the equipment is thoroughly cleaned after every
use.
 When using disinfection, protect your skin and eyes. Heed all
instructions on the disinfectant’s container and material
safety data sheet.
 Always make sure that the device is supplied with power. It
may only be interrupted in emergency situations.
 Ensure that there are no objects right next to the tub to en-
sure a safe up and down movement. Disregarding this instruc-
tion can cause bad injuries or damage the device.
 Don’t place any objects on top of the device, since due to
movement or vibrations, they can fall off - also into the tub.
 Adjustments and repairs must be carried out by authorized and
appropriately qualified persons only.
Caution: The safety rules and instructions in this operating
manual must be observed in order to ensure safe and
proper use of the equipment. All claims under guaran-
tee become void if these requirements are not met.

Functions
■ Functions
How the control panel works
Generally we can say that a lit button signals the availability of
the corresponding function (with the exception of Sound & Vision -
for details see the corresponding chapter). When you press the
button you activate its function and the light starts flashing. To
stop the function, just press the button again. When there is no
backlight behind the button, then the function is not available at
the moment (for instance: disinfection is not available when the
tub is full).
Standby mode
If the tub is empty and for 10 minutes no function is activated
(or in case that the main switch of the bathtub has been switched
on), then the bathtub goes into standby mode. In this mode all
functions are deactivated (with the exception of Sound & Vision,
which gets “frozen” in the state which it is in at that moment)
and locked. Only the sensor “ACTIVATION CARD” is illuminated with
a green backlight.
The standby mode a) prevents unauthorized use of the bathtub and
b) helps to save energy since due to the deactivation of almost
all functions the bathtub uses less electricity.
In order to return to normal mode, please, use the activation card
(see next subchapter).
Activation card
To use the tub again when in standby mode, gently
swipe the magnetic activation card over the green
backlit sensor “ACTIVATION CARD”. After 12 seconds
the device should return back to normal mode.
Note: Optionally you can also reactivate the bathtub without
the activation card. This option can be set in program
mode. If it has been turned on, then you can reacti-
vate the bathtub by pressing any button. (In case that
the function behind the pressed button is available,
it will also get activated immediately, e.g. raising
and lowering.) This means that with this option turned
on, the standby mode only helps to save energy but
does not prevent unauthorized use of the bathtub.

8
Raising and lowering the tub
The “UP” and “DOWN” buttons are used to raise or lower
the tub. The movement continues until the button is
released again. In the upper and lower end positions
the tub stops automatically. In the event of power
failure the bathtub can only be lowered, which is pow-
ered by the emergency battery. The movement is a bit
slower in this case than usual. Additionally the sym-
bol “MISSING POWER SUPPLY” is illuminated.
Opening & Closing the drain
In order to close the drain, ensure that the drain
plug is in place. Then turn the chromed overflow
clockwise. In order to open it, turn the overflow
counter-clockwise. (It is not necessary to remove the
drain plug.)
Filling the tub
When you press the button “TUB FILL” the tub starts
filling. The button starts flashing and the symbol
“TUB FILL TEMPERATURE” lights up. The water now flows
into the bathtub until the maximum filling level has
been reached or the button is pressed a second time.
When the bathtub is filled to the maximum level, then
the button will be darkened and disabled until the
recognized filling level drops again under the maxi-
mum. In case you want to add more water after auto-
matic deactivation, you can do so by means of the hand
shower.
Shower
The shower can be used at any time (except during cer-
tain parts of the disinfection procedure). To do so,
simply take the white hand shower from its holder and
press the button “SHOWER”. The button starts flashing
and the symbol “SHOWER TEMPERATURE” lights up. Press
and hold the trigger on the hand shower’s handle to
begin showering. When you press the button “SHOWER”
again, the shower is deactivated.
Functions

9
Functions
Setting the temperature
You can set the temperature for tub fill and shower
continuously. To do that, turn the knob of the mixing
valve to the desired position. The used temperature
will be shown in the temperature display.
Note: For safety reasons the temperature is mechanically
limited to 38 °C (standard mixer). To override this
security appliance, press the button on the knob. Thus
it is possible to turn the knob further and set a
higher temperature.
Caution: When setting the temperature to a value above 38 °C,
set it back to 38 °C or lower as soon as possible! In
the meantime, while the temperature is overridden, use
extreme caution with the hot water.
Temperature display tub fill & shower
This display shows the current tub fill respectively
shower temperature when they are in use. If the tub
fill is active, the symbol “TUB FILL TEMPERATURE” is
illuminated additionally to the flashing button “TUB
FILL”. If the shower is active, the symbol “SHOWER
TEMPERATURE” is illuminated additionally to the flash
ing button “SHOWER”. If tub fill and the shower are
active at the same time, both will have the same tem-
perature since there is only one mixing valve. If none
of these two functions are active, then the display
remains empty.
Caution: Always check the water temperature with your bare hand
(also when using the shower) before bringing the water
in contact with the patient.
Note: The symbols next to the temperature display only serve
as status indicators. You cannot activate any func-
tions with these.
Underwater light
The underwater light, if installed (being an alterna-
tive to the “Vision” function), can be used at any
time. By pressing the illuminated button the underwa-
ter light is switched on and the button starts flash-
ing. The underwater light slowly changes between 7
colours. (It cannot be fixed to one colour.) By press-
ing the button again the underwater light is switched
off.

10
Sound & Vision
The optional feature „Sound & Vision“ can playback mu
sic files which are stored on a USB stick on speakers
build into the tub body. Furthermore, by means of LEDs
on different sides it can suffuse the water with light
in various colours.
If this feature is installed in your GK bathtub, then
the buttons “PLAY/PAUSE” and “LIGHTS” will flash
slowly in a rhythm of 3-4 seconds (ready mode).
Sound
First of all ensure that a USB stick with readable mu-
sic files (mp2, mp3, wma) is inserted into the USB
port (on the side of the console). When pressing the
button “PLAY/PAUSE” all the recognized music files
will be played back, sorted by name (and the button
starts to flash faster, about 1x/second). Furthermore,
the buttons “NEXT” and “BACK are enabled and illumi
nated continuously. When pressing these buttons the
player switches to the next or previous (press 2x)
track. After playing the last track playback continues
again with the first track.
By pressing the button “PLAY/PAUSE” during playback,
it is paused (and the button starts to shine continu-
ously). When pressing it again, the playback contin-
ues. In case the pause exceeds 30 seconds, the player
resets itself to ready mode automatically. Thereafter,
a further playback would again start at the very be-
ginning. (In case the USB stick gets pulled during
playback or if it was not in the port at the start of
playback (the button still flashes about 1x/second),
then this “empty playback” must be “paused” before
(re-)starting a real playback.
The volume can be adjusted through the button “PLAY/
PAUSE” in combination with “NEXT” and “BACK”. By
pressing the buttons “PLAY/PAUSE” and “NEXT” together
the volume is raised. By pressing the buttons “PLAY/
PAUSE” and “BACK” together the volume is lowered.
Vision
When pressing the button “LIGHTS”, the LED lights are
switched to “slow continuous colour change” mode (and
the button starts to flash faster, about 1x/second). -
When pressing the button “LIGHTS” again, the colour
currently visible in that moment is fixed (and the
button starts to shine continuously).- Pressing the
button a third time will switch back to ready mode and
the LED lights off.

Ultrasound
On the GK Magic 2000 bathtub there is only one button
“HYDROMASSAGE/ULTRASOUND” for both of these functions,
since only one of these functions can be installed in
the tub at a time.
The ultrasound cleaning treatment is available only
when the tub is full. The button will be enabled and
lights up. Press the button to start the ultrasound
cleaning treatment. Press the button again to stop it.
It can be turned on and off until the overall treat-
ment time of 20 minutes (for each bathing cycle) is
exhausted. Thereafter the illumination of the button
stops and it can not be used until the next bathing
cycle.
Note: The ultrasound transducer is audible. The closer any
body parts are to the transducer plate the louder the
side noise becomes. This is a normal side effect of
the ultrasound cleaning treatment.
Caution: Do not apply the ultrasound cleaning treatment to
pregnant women.
While using the ultrasound cleaning treatment make
sure that the head of the patient stays above the wa-
ter at all times and the he/she is situated with his/
her feet towards the tub’s drain.
Also the patient’s feet should not touch the ultra-
sound transducer plate over a longer period of time
while the function is active. Touching it for a few
seconds is no problem, though.

Ultrasound cleaning FAQ:
What is ultrasound?
Ultrasound in effect consists of sound waves in a high
frequency in a non audible range for human ears (over
20 KHz). Of course these permeate, just like “normal”
sound waves, also water and solid bodies.
Ultrasound is applied in diverse areas in different
frequencies and with varying intensity. For the exami-
nation of pregnant women, for example, frequencies of
3.5 to 7.5 MHz but only very low intensities of 3 to
100 mW/cm² are used. For an ultrasound therapy with a
warming effect frequencies of 750 KHz to 2 MHz and in-
tensities of 100 mW to 3 W/cm² are used.
In our case of the gentle body cleaning underneath the
water frequencies of 25 to 30 KHz and low intensities
of about 100 mW/cm² are used.
How is ultrasound generated in the bathtub?
At the foot end of the bathtub there is a metal plate.
Behind it is the ultrasound transducer. The ultrasound
waves are generated there and spread out through the
bathing water.
What effect does ultrasound have regarding body cleaning?
Because of the ultrasound millions of tiny gas bubbles
are created in the water which collapse again very
quickly (cavitation). At the surface of the patient’s
body the energy, which is released when the gas bub-
bles collapse, abrades dirt and loose skin particles
in a gentle manner.
This cleaning process takes effect at all those areas,
where the skin is touched by the water.
What are the benefits of ultrasound cleaning versus manual clean-
ing (potentially with hydromassage)?
1) The cleaning with ultrasound in general is more
thorough. 2) It is also more gentle to the skin since
no scrubbing need to take place. 3) It means less work
for the caretaker. 4) The privacy of the patient can
be respected a little bit more. 5) The metal plate of
the ultrasound transducer can be cleaned more easily
than any hydromassage jets. 6) Besides the patient’s
body also the submerged surfaces of the tub itself and
of any additional equipment (e.g. lifts) are automati-
cally cleaned as well. This makes the scheduled clean-
ing of these items a bit easier.

13
Functions
Are there any persons which may not be exposed to the ultrasound
cleaning function?
In general (with the exception of pregnant women) the
ultrasound cleaning function may be used on all per-
sons which are also allowed to take a bath. In case
you are not sure, ask a medical doctor if the applica-
tion of the ultrasound cleaning (at 25 to 30 KHz and
about 100 mW/cm²) is safe for the patient’s health
condition. (Also see the following questions.)
May the ultrasound cleaning function be used on pregnant women?
For safety's sake pregnant women may not be exposed to
the ultrasound cleaning function. (Should it still
happen unintentionally, then there normally is no harm
to be expected, since the intensity used is low at 100
mW/cm². Still, one should not take unnecessary risks
regarding the life of others.)
May the ultrasound cleaning function be applied to people with
pacemakers?
We have no information about any disruption of a pace-
maker’s functionality because of ultrasound or an ul
trasound transducer.
May the ultrasound cleaning function be applied to persons with
implants or other metal objects in or on their body?
Implants or other metal objects are no problem.
For how long at a time may the ultrasound cleaning function be ap-
plied to a person?
The ultrasound used would not have any negative ef-
fects for the body, regardless of the duration of ex-
posure to it. Still, for the sake of usefulness and
practicality the ultrasound cleaning function has a
build-in time limit.
Should any bath additives be used during the application of the
ultrasound cleaning?
Bathing oils should be avoided, since these have a
negative impact on the effectiveness of the ultrasound
cleaning. However, shampoo may be used.

14
Hydromassage
The hydromassage therapy, if installed, is available
only when the tub is filled with water. In this case,
the button is enabled and illuminated. By pressing the
button the hydromassage jets are activated. Pressing
the button again deactivates them. The hydromassage
jets can be turned on and off until the overall treat-
ment time of 20 minutes (for each bathing cycle) is
exhausted. Thereafter the illumination of the button
stops and it can not be used until the next bathing
cycle.
Caution: Contrary to some of our other bathtub models, when a
massage hose coupling is installed, then also the jet
containing the coupling will be activated immediately
(without delay) upon activation of the whole function.
Shampoo & Bath additive
Both of these products, if installed, can be added at
any time. By pressing one of the buttons “SHAMPOO” or
“BATH ADDITIVE” the selected dispenser pump starts
running as long as you hold the button.
Note: The tube for the shampoo has a red marking on its suc-
tion end - the tube for the bath additive a blue mark-
ing at the alike spot.
If there is no liquid coming out of the system, make
sure that both boxes are full. After installing a new
box it might take a while to get all the air out of
the tubes. You possibly have to use the function for a
longer period of time.

Functions
Disinfection
Flowmeter
The flowmeter is used to adjust the mixture ratio be-
tween water and disinfectant. It is located at the
back of the console. It can only be calibrated during
a disinfection cycle while the disinfectant solution
is flowing. The table next to it should help you to
find the right value. Always follow the instructions
of the disinfectant manufacturer. The Flowmeter must
be calibrated after each connection of water tubes and
after changes in water pressure and after changing the
disinfectant’s composition. During use of the tub, pay
attention not to accidently alter its setting.
Disinfection procedure
In order to be able to start the disinfection proce-
dure 1) there must be disinfectant inside its con-
tainer and 2) the tub must be almost empty. If both
requirements are met, then the disinfection button
lights up.
Note: If the disinfection container should be empty the dis-
infection button is flashing fast (~4x/sec.).
To start the disinfection procedure take the red hand
shower from its holder and press the disinfection but-
ton. The button is flashing now. Spray all internal
tub surfaces with the disinfectant solution.
Caution: Protect your skin and eyes from the disinfectant solu-
tion. Follow all the instructions of the disinfectant
manufacturer.
Thereafter press the button again and put the hand
shower back into its holder.
After the necessary contact time (according to the
disinfectant’s manufacturer’s specifications) the tub
must be rinsed thoroughly. To do so, take the white
hand shower from its holder and press the shower but-
ton. Rinse all internal tub surfaces thoroughly.
When you deactivate the shower any hydromassage jets
are activated briefly in order to remove the disinfec-
tant solution from them. Ensure that no disinfectant
solution residues are left behind inside the tub.
Note: For safety reasons the disinfection procedure - once
started - cannot simply be aborted.
During the whole disinfection procedure most other
functions are disabled, especially the tub fill.

16
Functions / The bathing cycle
Note: If the disinfectant runs out while spraying, the whole
procedure must be restarted after replacing its con-
tainer. Since the procedure cannot simply be aborted
and the tub fill being disabled, therefore - once the
disinfection procedure has been started - you cannot
fill the tub again without enough disinfectant. How-
ever, the disinfection procedure can be skipped alto-
gether.
■ The bathing cycle
 Insert the drain plug into the drain. Close it.
 Adjust the tub shorter according to the body length of the pa-
tient and put the pillow into the right position. (When using
a stretcher lifter then this point does not apply.)
 To fill the bathtub, press the button “TUB FILL” and select a
pleasant fill temperature for the patient.
Caution: Always check the water temperature with your bare hand
(also when using the shower) before bringing the water
in contact with the patient.
 To add bath additive to the water (if installed available)
press the button “BATH ADDITIVE” for as long as you want to
add more.
 Once as the water has reached the desired level, stop the wa-
ter flow if necessary. Now help the patient into the bathtub
or lower the bathing lift into the water and adjust the bath-
tub to a comfortable working height.
Caution: Never leave the patient unattended inside the bathtub.
 If you want to use the shower at any time during the bathing
cycle, simply pick up the white hand shower from its holder
and press the button “SHOWER”. To start showering press the
trigger on the hand shower.
 To dispense shampoo (if installed) press the button “SHAMPOO”
for as long as you want more, while keeping your hand under
the shampoo dispenser.
 If so desired by the patient, activate any available therapy
treatment.

17
The bathing cycle / Care & Cleaning
 To finish, turn the chromed overflow knob in counter clockwise
direction, in order to open the drain. Lower the bathtub and
help the patient out of the water or remove the bathing lift
from the tub.
 Before you start a new bathing cycle you should thoroughly
clean the bathtub.
■ Care & Cleaning
Always clean the plastic parts wet or damp but never dry.
Any product used to clean or disinfect your GK bath must be free
from any abrasive, alcohol & corrosive ingredients. Never use any
kind of customary glass cleansers, solvents (e.g. acetone) or
similar detergents or dilutions. Never use harsh or pointed uten-
sils, e.g. rough clothes, scrubbing sponges, scouring pads or any
tools. If you are in any doubt about your usual cleaning products
please contact your GK representative before use.
Caution: Any damage caused by unapproved / unsuitable products
will not be covered by the manufacturer’s warranty.
Dark grey and transparent plastic parts:
The dark grey and transparent plastic parts may only be cleaned
with a maximum of lukewarm water and, if needed, a mild dishwash-
ing soap. We especially recommend our special plastics intensive
cleanser (details on request). For these parts of the tub only use
very fine textured chamois leather or a microfiber cloth.
For the best care for these parts we recommend our special anti-
static plastics care product (details on request).
Remaining tub body parts:
For the other mostly white parts, after use always rinse the bath
tub thoroughly with the shower hose. Any dirt which adheres to the
bathtub surfaces must be removed with a soft sponge or cloth and,
if necessary, customary detergents (besides the above mentioned
restrictions).
We recommend using our approved shampoo and bath additive products
with your GK bath. Other products may cause more persistent dirt
being harder to clean.

18
Care & Cleaning
We also recommend for you to polish the white bath tub body once a
month with car polish cream. This will give the bathtub a smooth,
water repellent surface and will make routine cleaning considera-
bly easier –it will also enhance the appearance of your GK bath.
From time to time the hydromassage jet
covers should be removed and be cleaned
together with the inlet and outlet aper-
tures separately.
To do so, unscrew the jet covers in
counter-clockwise direction off of the
tub surface (see pictures). Now clean
the covers, the inlet aperture and the
outlet aperture thoroughly with a suit-
able cleaning cloth.
Note: Do not use excessive force when re
-assembling the jet cover.
If you have any questions, please, con-
tact your GK representative.

Troubleshooting
■ Troubleshooting
Tub fill doesn’t work even though the function is active and the
light is flashing.
Check all the sieves and valves for dirt. If the problem still ex-
ists, then the electronic has to be checked. Contact your GK rep-
resentative.
The temperature regulation doesn’t work properly.
The thermostatic mixer is adjusted at 3 bar water pressure at both
supplies. If you have different water pressure it may be necessary
to do a readjustment. If the water pressure is about right, possi-
bly the cartridge is defective and has to be changed.
Very little water runs into the tub.
If the hot and cold water supply pressure deviate too much from
each other, then the mixing valve cannot work properly.
Disinfection doesn’t work and the button is flashing very fast
(about 4x/sec.).
The disinfectant container is empty. Replace it with a full disin-
fection container.
Disinfection doesn’t work and the button is flashing very fast
(about 4x/sec.) even though the container is full.
The disinfection sensor is defective and has to be replaced.
All the functions are disabled except the “UP” and “DOWN” buttons.
Probably the tub is still in the disinfection cycle. Finish the
procedure properly.
No shampoo or bath additive is dispensed even though the button is
flashing when it is pressed.
If the corresponding box is not empty, then there probably is air
in the tubes. Press the corresponding button for a longer time.
The hydromassage/ultrasound button doesn’t light up (with hydro-
massage/ultrasound being installed) even though there is more than
enough water in the tub.
The fill level sensor is defective and has to be changed.
The tub fill does not stop automatically.
The fill level sensor is defective and has to be changed.
All the functions are disabled except the “DOWN” button and the
symbol “MISSING POWER SUPPLY” is lit.
No power supply detected. Try to solve this problem as soon as
possible since otherwise the emergency battery will be completely
emptied.
