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
Raising & Lowering the tub
This tub allows caregivers to bathe patients in an er-
gonomic environment. Adjusting the tub to a comfort-
table working height enhances the bathing process. The
“UP” and “DOWN” buttons are used to raise or lower the
tub. The movement continues for as long as the button
is pressed. When the button is released, the movement
stops. In the upper and lower end positions the tub
stops automatically. In the event of power failure you
are still able to lower the tub with the integrated
emergency battery.
Note: The emergency battery is not integrated in every bath-
tub as it is an option.
Alternatively to the buttons on the control panel the
tub can also be raised or lowered by means of the foot
switch. It works with air pressure and is connected to
the electronics through thin air filled plastic tubes.
The higher air pressure, when stepping on the switch,
activates the corresponding function on the electron-
ics (inside the casing). Thus, the foot switch is
separated from all electricity and may get wet without
concerns.
Note: The foot switch is not included with every bathtub as
it is an option.
Opening & Closing the door
The door in the side of the bathtub can be opened and
closed manually only. In order to open it the handle
must be turned clockwise. In order to close it,
counter-clockwise. From the open to the closed posi-
tion of the handle, a rotation of about 60-70° is nec-
essary (a bit less than a quarter of a circle).
Opening & Closing the drain
To close the drain, turn the chromed overflow knob in
clockwise direction. To open, turn it in counter
clockwise direction.
Functions

8
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 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 always shows the current tub fill respec-
tively shower temperature.
Caution: Always check the water temperature with your bare hand
(also when using the shower) before bringing the water
in contact with the patient.
Filling the tub
Open the “TUB FILL VALVE” (in counter-clockwise direc-
tion) to fill the tub with water. When your desired
filling level is reached close the valve again to stop
the water flow.
Filling the tub with control panel (if installed)
If the knob of the “TUB FILL VALVE” is not present,
then the tub can be filled by pressing the button “TUB
FILL”. Now the water keeps flowing until the maximum
filling level is reached or the button is pressed a
second time. If the water level is not high enough af-
ter the automatic fill stop, you can press and hold
the button “TUB FILL” for additional water flow.
Note: If you want to use the door for entering the bathtub,
then fill the bathtub at first only up to below the
doorstep. To do that when using the control panel, you
must actively press the button at the right time.
Functions

9
Shower
The shower can be used at any time. To do so, pick up
the white hand shower from its holder and open the
“SHOWER VALVE” (in counter clockwise direction). Press
and hold the trigger on the hand shower’s handle to
begin showering. When you are finished showering,
close the valve. Afterwards release the pressure from
the hose by briefly pressing the trigger once again.
Then put the hand shower back into its holder.
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 corresponding dispenser pump
starts running for 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.
Underwater light
The underwater light, if installed, (being an alterna-
tive to the “Vision” function), is located at the foot
end of the bathtub and is available at any time. It is
operated by means of an air switch (see picture to the
left) by which any contact of splash water with elec-
tric switch elements is prevented. Pressing the
chromed button switches the underwater light on. The
underwater light slowly changes between 7 colours. (It
cannot be fixed to one colour.) By pressing the button
again the underwater light is switched off.
Functions

10
Functions
Hydromassage
This function, if installed, is available only when
the bathtub is filled with water. To activate it,
press the button “HYDROMASSAGE”. To deactivate it,
press the button again. The maximum overall treatment
time for each bathing cycle is 20 minutes. Once it has
been used up the function cannot be used anymore until
the next bathing cycle.
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
a USB port and an additional control panel are mounted
to the outside of the console (USB on the side, con-
trol panel at the top right front; see pages 4 to 6).
Sound
First of all ensure that a USB stick with readable mu-
sic files (mp2, mp3, wma) is inserted into the USB
port. Now, pressing the button “PLAY/PAUSE” will play
back all the recognized music files, sorted by name.
Pressing the buttons “NEXT” and “BACK” 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. When pressing it again, the playback
continues. 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 beginning. (In case the USB stick gets pulled
during playback or if it was not in the port at the
start of playback, then this “empty playback” must be
“paused” before (re-)starting a real playback.)
The volume can be adjusted by pressing the buttons “-”
and “+”.
Vision
When pressing the button “LIGHTS”, the LED lights are
switched to “slow continuous colour change” mode. -
When pressing the button “LIGHTS” again, the colour
currently visible in that moment is fixed. - Pressing
this button a third time will switch back to ready
mode and the LED lights off.

11
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.
Manually controlled disinfection procedure (model with
disinfection valve)
The bathtub may only be disinfected when the tub is
empty. To perform the disinfection procedure 1) take
the red hand shower from its holder and 2) open the
disinfection valve (in counter clockwise direction).
3) Press and hold the trigger directly on the hand
shower and spray all internal tub surfaces with the
disinfectant solution.
Caution: Before every disinfection procedure, ensure that there
is enough disinfectant available in its container.
Protect your skin and eyes from the disinfectant solu-
tion. Follow the instructions of the disinfectant
manufacturer.
4) Close the disinfectant valve (in clockwise direc-
tion). 5) Afterwards, release the pressure from the
hose by briefly pressing the trigger once again and
6) put the hand shower back into its holder.
After the necessary contact time (according to the
manufacturer’s specifications) the bathtub must be
rinsed thoroughly. To do that 7) take the white hand
shower from its holder, 8) open the shower valve (in
counter clockwise direction) and 9) press and hold the
trigger directly on the hand shower. Rinse all inter-
nal tub surfaces thoroughly. Ensure that no disinfec-
tant solution residues are left behind inside the tub.
10) Close the shower valve (in clockwise direction).
11) Afterwards, release the pressure from the hose by
briefly pressing the trigger once again and 12) put
the hand shower back into its holder.

12
Functions
Electronically controlled disinfection procedure
(model with disinfection button)
In order to be able to start the disinfection proce-
dure there are two requirements which must be met:
a) The tub must be empty or almost empty. b) There
must be enough disinfectant inside its container. If
both requirements are met, then the disinfection but-
ton lights up.
Note: If the disinfection container should not contain
enough disinfectant, then the disinfection button is
flashing briefly in a rhythm of about 1.5 seconds.
To perform the disinfection procedure 1) take the red
hand shower from its holder and 2) press the button
“DISINFECTION”. Now the button is flashing slowly
(about 1x/sec.). 3) Press and hold the trigger di-
rectly on the hand shower and spray all internal tub
surfaces with the disinfectant solution.
Caution: Protect your skin and eyes from the disinfectant solu-
tion. Follow the instructions of the disinfectant
manufacturer.
After about 40 seconds the disinfection shower stops
automatically. 4) If the 40 seconds were not long
enough for you to spray all internal tub surfaces,
press the disinfection button again twice. Thereby you
are restarting the disinfection procedure and have an-
other 40 seconds available. 5) After the 40 seconds
are up and spraying is completed, ensure that the
pressure is released from the hose by briefly pressing
the trigger on the hand shower once again (without
flowing disinfection solution). 6) Put the hand shower
back into its holder. The disinfection button should
still be blinking.
After the necessary contact time (according to the
manufacturer’s specifications) the bathtub must be
rinsed thoroughly. To do so, 7) press the still blink-
ing disinfection button. The button is now illuminated
continuously. Now follow the steps 7 to 12 of the
chapter “Manually controlled disinfection” on page 11.
Note: While spraying the disinfectant solution during an
electronically controlled disinfection procedure the
tub fill is disabled. If the disinfectant runs out
while spraying, the whole procedure must be restarted
after replacing its container. Otherwise it cannot be
completed nor can it be stopped. Therefore, once the
electronically controlled disinfection procedure is
started, you cannot fill the tub again without enough
disinfectant. However, the disinfection can be skipped
altogether.

13
The bathing cycle
■ 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.
 To fill the bathtub, open the inflow valve (turn in counter
clockwise direction) or press, if installed, 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.
 As soon as the water level reaches up to close below the door-
step, stop the inflowing water, help the patient into the
bathtub and close the door.
Caution: Never leave the patient unattended inside the bathtub.
 Continue filling the bathtub and bring it to a comfortable
working height. Once the desired filling level has been
reached, stop, if necessary, the inflowing water.
 To add bath additive to the water (if installed) press the
button “BATH ADDITIVE” for as long as you want to add more.
 If you want to use the shower during the bathing cycle, simply
pick up the white hand shower from its holder, turn the shower
valve in counter clockwise direction and 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.
 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. BEFORE opening the door, en-
sure that the water level has dropped below the doorstep.
 Before you start a new bathing cycle you should thoroughly
clean the bathtub.

Care & Cleaning
■ 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.
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.

15
Care & Cleaning / Troubleshooting
From time to time the hydromassage jet cov-
ers should be removed and be cleaned to-
gether with the inlet and outlet apertures
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 thor-
oughly with a suitable cleaning cloth.
Note: Do not use excessive force when re-
assembling the jet cover.
If you have any questions, please, contact your GK representative.
■ Troubleshooting
The temperature regulation by means of the thermostat mixing valve
doesn’t work properly.
The thermostatic mixer is adjusted at 3 bar flow pressure at both
supplies. If you have different supply pressure it may be neces-
sary to do a readjustment. If this does not help, clean the sieves
behind the chromed cover of the thermostatic mixing valve. Also,
the cartridge could be defective and might have to be changed.
The display reads F0 or F1.
The temperature sensor is defective and must be changed.
Very little water runs out of the tub.
Check the pressure of the hot and cold water supply because the
mixing valve does not work if one of them is too low.
When using the disinfection shower, water is indeed flowing out
but no disinfectant is being sucked into the water.
 Check if there is still enough disinfection liquid in the dis-
infection container.
 Check if the flowmeter is properly adjusted.
 If the Flowmeter shows nothing then the injector could be de-
fect and can not suck any disinfectant into the water.
The display shows nothing and the up/down buttons are not working.
Probably your bathtub does not have an emergency battery installed
and either a fuse has burned out or the power supply broke down.
The water does not stop automatically at the maximum fill level.
The fill level sensor is defective and has to be changed.

16
Troubleshooting / Maintenance / Service
No bath additive or no shampoo is dispensed.
 Either the corresponding box is empty -> exchange the box
 or there is air in the tubes -> keep the button pressed for a
longer period of time,
 or the dispenser openings are blocked -> clean them,
If you have any questions, please, contact your GK representative.
■ Maintenance
 Regularly (at your own discretion) monitor the fill level of
the disinfectant container (if installed).
 Regularly (at your own discretion) monitor the fill level of
the shampoo and bath additive containers (if installed).
 Once a month, check the sieves in the hand showers and clean
them if necessary.
 Once a month, check the proper condition of the shower hose
and, if installed, of the disinfection shower hose, as well as
of any externally visible connections.
 Once a month, check the bathtub for any cracks or other dam-
ages.
Caution: Should you notice any damage to the bathtub either
during maintenance or at any other time, then the
bathtub may not be used any further from that point
onward, until the damage has been assessed and, if
necessary, repaired.
■ Service
At least once a year a service or safety inspection in accordance
with Medical Device Directive (MDD) is mandatory.
 Remember that GK service is unmatched in quality and also with
regards to warranty issues. GK will only consider itself li-
able for safety-related matters if repairs, modifications etc.
are exclusively carried out by our service team or by agents
authorized by us.
In the event of problems occurring, clear and detailed information
about symptoms, type and serial number (see type plate) will help
us to respond promptly.
