■ For your safety
 Make certain that this bathing system is operated only by
trained personnel.
 Always check the water temperature before the client enters
the bathtub or when the shower spray is applied to the client.
 Make certain that the equipment is thoroughly cleaned after
every use.
 Make sure that each client is assessed for its ambulatory ca-
pability, ensuring the client’s safety when entering and exit-
ing the bathing system (utilize handgrips, correct entry
height, correct client transferring device, etc.).
 When using disinfection, wear rubber gloves and eye protec-
tion. In case of eye or skin contact, follow the procedures on
the disinfectant container and material safety data sheet.
 Always make sure that the device is supplied with power.
 Make sure that there are no materials right next to the tub to
ensure a safe up and down movement. Disregarding this tip can
cause bad injuries or damage the device.
 Don’t deposit any things on the bathtub. Because of movement
and vibrations, things can fall on the floor or in the tub.
 We want to point out that a lifting bathtub is a nursing tub
and the bathing of the inhabitant has to be effected by use of
a suitable lifter.
 Should no lift be used we recommend to furnish the bathtub
with handles.
Note: The safety rules and instructions in this operating ma-
nual must be observed in order to ensure safe and proper
use of the equipment. Adjustments and repairs must be
carried out by authorized and appropriately qualified
persons. All claims under guarantee become void if these
requirements are not met.

Preperations for bathing
4
■ Preparations for bathing

■ Functions
How the control panel works
Status LEDs are located next to most of the keys. These give you
information about the current operating state of the respective
function.
 Dark not available, switched off
 Lighting available, switched off
 Flashing switched on
 Fast flashing too little disinfection liquid (only
by Disinfection)
Activation card
After switching on the tub for the first time, or in
standby mode, all the functions are disabled. To
make the tub work, use the magnetic card and skim
over the symbol. After a few seconds the device
should turn to normal mode.
Note: Optionally you can use the device without magnetic
card. If this option has been implemented you can
start by pressing a button.
Standby mode
This mode saves the device from unauthorized use and increases the
lifetime of the whole product. In this mode the current consump-
tion is trimmed to a minimum, which helps to save energy. The tub
automatically switches to standby when it’s empty and not used for
a while.
Note: After 10 minutes no function was in use the device is
changing in the standby mode, if the tub is empty.

10
Functions
Raising & Lowering the tub
This tub allows caregivers to bathe clients in an
ergonomic environment. Adjusting the tub to a com-
fortable working height enhances the bathing pro-
cess. 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 re-
leased, the movement stops. In the upper and lower
end-positions the tub stops automatically.
Tilting the tub
Using both of these buttons you are able to tilt the
tub. The movement continues for as long as the but-
ton is pressed. In the upper and lower end-position
the tub stops tilting automatically.
Opening & closing the door
To open or close the automatic door you can use
these buttons. The movement continues for as long as
the button is pressed. In the upper and lower end-
position the tub stops moving automatically. The
“door open” button is also to unlock the door, but
to do this the tub must be empty and completely
tilted forward.
Note: Check that the door is free from objects, if you are
closing it, because it can cause damages.
Note: Should your GK Relax be equipped with an manual
lock, than you have to manually open and close the
door.
Emergency button
This button unlocks and subsequently opens the
door. In this case it doesn’t matter if there is
water in the tub or which position the tub is in.
Only use the button in an emergency situation.
Note: The emergency button must be pressed for longer
than 2 seconds before it is unlocking the door. In
the case of a short unintentional activation it
will nothing happen.

Locking button
With this button you can activate the locking de-
vice. As safety feature the locking device activates
after pressing the button for 2 seconds. Furthermore
you have to hold the button until the door is
locked, or it will open again. It is only possible
to activate the locking device if the door is com-
pletely closed.
Note: Be sure that the door is in the right position be-
fore you lock the door.
Note: Should your GK Relax be equipped with an manual
lock, than use the lock lever to lock and unlock the
door.
Setting the temperature
You can set the temperature for tub fill and shower
to any desired value by turning the mixing valve
tap. The selected temperature will be shown in the
display.
Note: For safety reasons the temperature is mechanically
limited to 38 °C (Standard-Mixer). To override this
safety feature, press the red button on the knob.
Now it is possible to select a higher temperature.
Use extreme caution when overriding the temperature
limit. In the disinfection cycle you should always
use the maximum shower temperature. This guarantees
a better elimination of bacteria.
The thermostatic mixer is adjusted at 3 bar flow
pressure at both supplies. If you have different
supply pressure it may be necessary to do a read-
justment.
11
Functions
Temperature display tub fill & shower
This display always shows the actual filling re-
spectively shower temperature when they are in use.
If none of these functions are active, the display
shows a double minus.

Closing & Opening the Drain (Draining the Tub)
To open or close the drain, turn the chrome drain
plug knob in the appropriate direction. We recommend
closing the drain system when the inflow is active.
Functions
12
Filling the tub
When you press this button the tub starts filling
and the light on the button starts flashing. The wa-
ter stops running when the maximum filling level has
been reached. Then the button will be disabled until
you drain the tub again. You can also stop the func-
tion at any time by pressing the button. If the tub
is full you can hold the button down for more than 2
seconds to continue filling until you release it.
Note: To fill the tub to the maximum the tub must be in
working position.
Shower
The shower can be operated at any time except during
parts of the disinfection procedure. To activate the
shower, press the button and remove the white shower
wand from its holder. The light on the button starts
flashing. Press and hold the black trigger directly
on the white shower wand to begin showering. After
you have returned the wand to its holder and pressed
the button again, the water flow is automatically
shut off to prevent spillage.
Note: In the disinfection cycle you should always use the
maximum temperature for shower. This guarantees a
better elimination of bacteria. For safety reasons
this function will be automatically disabled after a
few minutes. But you can activate it again by press-
ing the button.

Functions
13
Shampoo & Bath additive
Both functions can be used at any time if there is
water in the tub. By pressing the button the se-
lected dispenser pump starts running as long as you
hold the button. If there is no liquid coming out of
the system, make sure that both boxes are full. The
liquid is coming out on the fill in spout.
Note: When you install a new box it might take a while to
get all the air out of the tubes and the whole sys-
tem. You possibly have to use the function more than
once and for a longer period of time. Always make
sure that the caps are completely screwed on the
thread.
Hydro-massage
Hydro-massage is only available when there is enough
water in the tub. The button will then be enabled
and the light on the button illuminated. Press the
button to start the function. The therapy will last
as long as the factory set time has been elapsed.
Then the button will be disabled until the next bath
cycle. You can stop the therapy at any time by
pressing the button.
Setting the intensity
If the hydro-massage is enabled you can adjust the
intensity. At the beginning of the therapy the in-
tensity is on the lowest level. Press the “+” or “-
“ button to change the intensity.

Functions
14
Sound & Vision
The feature „Sound & Vision“ can playback music 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.
When your GK tub is activated and the optional fea-
ture “Sound & Vision” is installed, then the buttons
“Play/Pause” and “Lights” will flash slowly in a
rhythm of 3 seconds (ready mode).
Sound
First of all ensure that a USB stick with readable
music files (mp3, wma, aac) is inserted into the USB
port (behind the maintenance flap)! 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). Furthermore, the buttons
“Back” and “Next” are released and illuminated con-
tinuously. When pressing these buttons the player
switches to the previous (press 2x) or next track.
The volume can be adjusted by pressing the buttons
“+” and “-”. (These buttons first of all regulate the
intensity of hydromassage. Therefore, the music’s
volume can only be adjusted when this function is not
active.)
When pressing the button “Play/Pause” again, the
playback of the music is paused (and the button
starts to shine continuously). When pressing it a
third time, the playback continues. In case the pause
exceeds 30 seconds, the player resets itself to
ready mode automatically. Thereafter, a further play-
back would again start at the very beginning. (In
case the USB stick got pulled during playback or if
it was not in the port at the start of playback (the
button flashes faster), then, after (re-)inserting
the stick, the button “Play/Pause” must be pressed 2x
in order to (re-)start the playback.)
Vision
When pressing the button “Lights”, the LED lights are
switched to “slow continuous colour change” mode (and
the button starts to flash faster).
When pressing the button “Lights” again, the colour
currently visible in that moment is fixed (and the
button starts to shine continuously).
Pressing this button a third time will switch back to
ready mode and the LED lights off.

Functions
15
Disinfection
The bathtub can be disinfected only when the tub is
empty. If there is water in the tub, then the light
on the button is invisible. Press the “DISINFECTION”
button and remove the red shower wand from its
holder. The light on the button should start flash-
ing. When activated, an accurately measured amount
of disinfectant is directed into the wand for opti-
mum disinfection and cleaning. Press and hold the
black trigger directly on the red shower wand and
spray all internal tub surfaces including each
hydro-massage jet. Replace the disinfection wand
into its holder and press the button again. After
the prescribed contact time, press the “SHOWER” but-
ton and use the white shower wand to rinse the inte-
rior tub surfaces thoroughly. For cleaning, maximum
temperature should be selected. To complete the
whole cycle disable the shower. Then the hydro-
massage jets will be turned on for a few seconds.
Note: During the whole disinfection procedure all other
functions are disabled. For safety reasons you can-
not fill the tub again until the disinfection proce-
dure has been fully completed. If the disinfection
container is empty, the light will flash rapidly.
When using disinfection, wear rubber gloves and eye
protection. In case of eye or skin contact, always
follow the procedures on the disinfectant container
and material safety data sheet of the product you
are using. In the event of contact, obtain medical
attention as soon as possible.
Flowmeter
The flowmeter is used to adjust the mixture ratio
between water and disinfectant. The table next to it
should help you to find the right values. Always
follow the instructions of the liquid manufacturer.
Generally the flowmeter setting should be done when
you first install the tub.

16
Care & Cleaning of the tub
■ Care & Cleaning of the tub
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.
Note: Any damage caused by unapproved / unsuitable products will
not be covered by the manufacturer’s warranty.
For cleaning, 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).
Always clean the plastic parts wet or damp but never dry.
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.
Once in a while, the door seal should be treated with talcum to
give the seal a smooth surface. This way the door will not stick
to the door frame.
A disinfection cycle should always be performed after cleaning.
Where fitted, the hydromassage jet coverings
should also be cleaned & disinfected (see pic-
tures).
To do that, unscrew the jet cover anti-
clockwise. Now clean the cover, the inlet aper-
ture and the outlet aperture thoroughly.
Re-assemble the jet cover by rotating it clock-
wise.
Note: Do not use excessive force!
If you have any further questions or require more information
please contact your local GK representative, who will be happy to
advise.
