parts of the body under the backrest or under the leg rest (ill.1).
Ill. 1
Observe the warning instruction notices on the bed and never put your hands
between moving parts.
Spline function:
All drives of this bed have a spline function. This means that the drives only
exert a force for lifting and that the relevant parts are lowered by their own
weight. This prevents parts of the body or objects being crushed under the
backrest and/or the leg rest. However, the weight of the various parts of the
bed is such that injury cannot be ruled out completely in spite of the spline
function, and special care is called for here (ill.1).

2.1 B e f o r e f i r s t u s e - T r a n s p o r t / U n p a c k i n g
Before installing the bed, make sure that sufficient space has been planned for
the bed so that it does not bump against any other objects when fully unfolded
(see appendix on Space Requirements). The beds are delivered to customers on
special pallets and in boxes in some countries. The bed is then fully horizontal
and the upholstery is already in place.
As a rule, the bed is delivered by our own staff. If supplied by an external
carrier, the following applies:
The bed is delivered on a special pallet in a box. Carefully open the top of the
box. Do not use any sharp objects which might damage the upholstery.
Do not lift the bed, but first remove the upper carton cover. You can then lift the
sleeve up and put it aside.
2.2 T r a n s p o r t a i d s
Do not hold the bed by its upper structure (headrest, backrest, armrests or leg
rest) to lift it. If subjected to a force, these parts will give way (spline function).
You can use our special carrying aids (ill. 3) for better handling, following the
instructions below:
To get the bed off the pallet, you must first raise it through approx. 8-10 cm;
you will have to connect it to a wall outlet for this. Now press the relevant
function key (first series of buttons on the hand switch, suspended from the side
- see ill. 2).
Ill. 2
Now pull the mains plug from the socket again. Lift the inner of the two wooden
shells until the bore holes for the four special carrying aids are visible (ill. 3).
You can now screw in the carrying aids in pairs at the front and at the rear; the
bed is ready to be transported. Ideally, four people should lift and position the
bed in the location of your choice.

Caution: danger of injury due to heavy load. Weight of the bed: 125 kg
(without water cushions).
If the floor is not perfectly flat, the stability of the bed may have to be adjusted
to the floor surface by adjusting the setscrew.
If you have found a suitable location with sufficient space (see appendix 1) for
the bed, unscrew the carrying aids and store them in case you ever have to
transport the bed again. The bed has already been fully fitted out with the
upholstery.
Caution - collision: You must remove the carrying aids before using the bed.
Caution - collision of the inner shell with the outer shell: After removing
the carrying aids you must push the inner shell of the bed down again, so that it
rests on the steel structure of the base.
Ill. 3
2.3 I n s t a l l a t i o n - c o n n e c t i o n
A wall socket must be nearby. The mains lead is approx. 250 cm long. Do not
run the bed over the mains lead (danger of the lead being crushed, danger of
electric shock) or the hand switch lead (danger of the lead being crushed, faulty
operation).
Danger of tripping: Lay the mains lead so that no one can trip over it.
The mains lead and the hand switch lead must remain clear of moving parts to
avoid the danger of their being crushed and/or electric shocks.

The Amphibia bed can be used either with water or foam cushions (point 3.1).
The treatment bed has four electric adjusting motors (see General instructions).
The hand switch enables you to adjust the right height, inclination, backrest and
leg rest positions quickly and comfortably. You can use the memory functions
(M1; M2, M3, M4) to store and call up the 4 positions you use the most. You can
always change and save them when required (see Memory function 3.2).
3.1 A m p h i b i a w i t h o u t w a t e r c u s h i o n s
First remove the upper heating to use the Amphibia without water cushions. The
plug-and-socket connections of the heating under the water cushions must be
disconnected for this. The upper heating can then be removed from the pockets
in the water cushions. The water cushions can now be removed one by one. You
can now place the enclosed upholstery section in the gap thus created. (ill. 4)

or M4. A short beep will now sound to confirm that the position has been stored.
4.0 S e t t i n g s
4.1 H e i g h t
The height of the Gharieni Amphibia can be adjusted from approx. 55 cm to
approx. 90 cm.
The access height is the lowest seat height. It is approx. 55 cm. This height
enables the customer to comfortably sit or lie on the bed from the side.
The height adjustment is operated electrically. Press the corresponding function
key on the hand switch (first row of buttons on the hand switch, see chapter 3.1
Hand switch).
4.2 B a c k r e s t
This is also adjusted electrically. The backrest inclination can easily be adjusted
by means of the hand switch (second row of buttons on the hand switch,
chapter 3.1 Hand switch).
4.3 H e a d r e st
This can be adjusted manually and continuously. The side lever for the gas
spring enables the headrest angle to be set as required (positive and negative
through an adjustment range of 30°). Release the lever to lock the headrest into
position (ill. 6).
(ill. 6)

GHAR I ENI beds

Override function: This enables the gas spring to be extended without having
to operate the lever. This means that the headrest and the armrests can be
raised from their lower positions without operating the gas spring lever.
The headrest cushion has a nose slit for back massages. The nose slit cover is
easy to remove (ill. 7).
Ill. 7
4.4 A r m r e s t s
The individual armrests of the Gharieni Amphibia can be lowered manually by
means of gas springs, similar to the headrest. Simply press the lever on the
relevant side and exert slight pressure to adjust the armrests downwards. Pull
the armrest up by hand to raise it (override function). This makes the bed
extremely suitable for back massages (ill. 8).
(ill. 8)
4.5 S e a t i n c l i n a t i o n
The seat inclination is also adjusted electrically. It supports the complete thigh
area to the knee joint (third row of buttons on the hand switch, chapter. 3.1
Hand switch).
4.6 L e g r e s t
The leg rest of the bed can be adjusted independently of the backrest and the
inclination using the hand switch; it supports the entire calf section from the
knee downwards (fourth row of buttons of the hand switch, chapter 3.7 Hand
switch).
The Amphibia offers many possible adjustments, making it suitable for many
different uses.

GHAR I ENI beds

Again, when lowering the leg rest, there must not be any objects under the leg
rest. "Danger of crushing"
Regardless of the lying surface adjustment, never use the head, back, leg or
foot rests to support your full body weight.
In general, no extreme force should be exerted on these parts! If this instruction
is not observed, the support structure of the bed may be damaged, resulting in
the risk of personal injury due to the chair tipping over and breaking.
Danger of injury! While setting the optimum treatment position for your
customer, make sure that there is nothing between the parts of the bed which
might get clamped.
For reasons of safety, the treatment bed will only move while you are pressing a
button on the hand switch. The movement stops immediately when you release
the button.
4.7 E x t e n d i n g r u n n e r s
The Amphibia bed has a special construction enabling runners to be extended in
order to move the bed. Proceed as follows:
First move the backrest up (as described) using the hand switch. Remove the
cover from under the backrest so that you can easily reach the lifting device
(see ill. 9).
Now pull the lever towards you or push it all the way to the other side.
The runners are extended and the bed can be moved. Note! Do not move the
bed yet!
Runners retracted Pull the lever Runners extended
Ill. 9
First pull the mains lead from the wall outlet, wind it properly and stow it away
so that the bed cannot run over it while being moved. Do not retract the runners
until the bed is in its required position and you have ensured that the lead
cannot be damaged.
Always make sure that the bed is standing on its stationary adjustable feet.
If the bed is only standing on the moving runners there is a risk of it rolling
away, e.g. when somebody leans against it.
Never extend the runners while there is somebody on the bed
This rolling mechanism is not suitable for transporting people.

The water cushions have a pocket (over the water cushion), into which the
enclosed upper heating mat can be inserted.
The upper heating mat has two connection pipes; the longer of the two pipes
must point toward the foot end.
After the upper heating mat has been slid over the water cushions, both
connections of the upper heating mat must be connected to the connection
bushes of the lower heating mat (ill. 10).
The heating only works when both heating mats (upper/lower) have
been connected.
Only use the heating mats in combination with the filled water cushions,
otherwise there is a risk of the lower heating mat overheating.
The heating cables must be run under the water cushions, on their sides,
without there being any tension on the cables.
Both heating mats can be controlled from the heating control panel (ill.14). The
heating parameters can be set according to your own preferences.
