INSTALLATION
Powering the device
At all time, the primary voltage on the device can be removed safely by unplugging the
unit's power cable connected to the wall socket for this purpose. Ensure the power cable is
always accessible.
Note that this device is of Class II and that, for this reason, the power plug isn’t grounded.
WARNINGS ABOUT POWER TO THE UNIT
▪Connecting the device to a supply network that has no grounding terminal
increases RISK OF ELECTRIC SHOCK;
▪After accidental and significant spill of liquid on electronic components, cables and
/ or motors the operation of these components may be affected. You should
immediately disconnect the bed and then remove the user from the bed, clean and
inspect the bed by qualified technicians. The bed can be returned to service only if
it has been properly cleaned and inspected. Not following these instructions could
jeopardise the integrity of the device and could lead to SERIOUS INJURY.
▪Make sure the power cable is always at a safe place during the use of the device to
avoid damaging it and causing SERIOUS ELECTROCUTION INJURY.

19P03-DOC01E REV-3

Verification before putting into service
The following verifications are required to ensure that no damage occurred during
transport of the bed:
▪(If applicable) Check that the packaging of the device has no apparent damage;
▪(If applicable) Unpack the device from its packaging;
▪Visually inspect if the device appears to be in good condition;
▪Connect the device power cable;
▪Allow the device to be connected for at least 48 consecutive hours;
▪Then verify that each function of the device operates according to the operating
instructions provided in this manual (see section 3);
▪Unplug the power cable and operate the actuators to verify the battery.
Note that the verification of CPR function should be performed with a mattress and a
person adequately leaned otherwise it might not work. If damage or malfunction appear
on the bed, without hesitation contact the Technical Services Department of Rotec
International.
WARNINGS ABOUT VERIFICATION
▪Ensure that the power cables of electrical devices that are nearby do not get caught
in the moving parts of the device. Not doing so could lead to SERIOUS INJURIES
BY ELECTROCUTION.

Positioning in the operating environment
To install this bed model, place it horizontally at a distance of at least 127 mm (5 inches)
from the wall. In the same manner, check that no object obstructs the end of the feet
section and then apply the brakes (see section 3.2)
It is therefore possible to use the bed without worrying about the risk of contact with the
wall.

Installation/Replacement of the mattress
Use a mattress corresponding to the recommended specifications. Ensure that the
platform configuration is matching the mattress. (See Mechanical Specifications)
Lay the mattress on the device and insert it in between the rail guards of the platforms.
Notice that the mattress must be compressed to be inserted. Otherwise, the platform
adjustment is inappropriate for the dimensions of the mattress.
WARNINGS ABOUT FEATURES AND SPECIFICATIONS
▪Use a mattress of the correct size and adapted to the platform size in order to avoid
RISKS OF ENTRAPMENT between the siderails and mattress which can lead to
DEATH.

WARNINGS ABOUT THE USE OF ELECTRICAL FUNCTIONS
▪If the user's physical condition requires it, and that, for his own safety, lock the
movement of the bed functions intended to be used by the patient and place the bed
in the low position, the platforms horizontal and bed rails in the raised position;
▪Ensure that no body part exceed the mattress and that there is nothing interfering
under the platform of the bed before activating the CPR function. SERIOUS
INJURIES may occur if this function is not used properly.
▪CPR function should only be USED IN CASE OF EMERGENCY ONLY. Using
this function for other purposes could lead to SERIOUS INJURIES to the patient
or operator.

17
WARNINGS ABOUT THE USE OF ELECTRICAL FUNCTIONS (CONTINUED)
▪Always position the bed at a reduced height when the patient is sleeping or
unattended to reduce the RISK OF FALLS that could lead to INJURIES.
▪Do not leave a table or other device requiring access under the bed when it is
lowered down because this will cause SERIOUS MECHANICAL DAMAGE.
▪Always make sure no objects or equipment hinders the movement of the movable
parts of the bed before activating a motion controls, such as: patient or staff limbs,
medical equipment, etc. this could result in SERIOUS INJURY AND / OR
DAMAGE TO EQUIPMENT.

18
Moving the device
To move the device, it is recommended to raise the bed at least 150mm (6 inches) from
its lowest position in order to facilitate access to the pedal. To operate the system, place
the pedal in one of the following three positions:
DIRECTIONAL
To limit the head right
wheel to move in a straight
line and remove all
restrictions to the other
wheels.
Press on the green side of
the pedals.
NEUTRAL
To remove all restrictions
and allow the bed to move
in any direction:
Place the pedals
horizontally.
BRAKE
To apply the brake and
completely immobilise the
bed:
Press on the red side of the
pedals.
When the bed is heavily loaded, it is recommended to have two persons to move it.
WARNINGS ABOUT THE SYNCHRONISED BRAKE SYSTEM
▪Always apply the brakes after moving the bed or when a patient is on the bed
since not doing so could cause INJURIES to the patient when he or she gets in
and out of bed.
▪Always verify that the brakes are well locked after they are activated by trying to
move the device.

19
Side rails
To lower one side rail,push the lever located underneath the mattress near the mechanism
and move the side rail downwards with a rotating movement. For better security, the side
rail locks after being activated. Press again on the lever and move the half-length side
rail until it stops in the lowest position.
To raise the side rail, pull the side rail upwards by a rotational movement. Then, make sure
that the side rail is completely locked at the highest position by trying to move it sideways.
WARNINGS ABOUT SIDERAILS USE
•When raising the siderails in close position, always make sure that the side rail is
completely locked at the highest position by trying to move it sideways in order to
avoid RISKS OF FALLING.
•The side rails are designed to prevent accidental falls only. They should not be used
to prevent the patient from leaving the bed, to assist the patient to turn over in bed or
as a restraint. Is the responsibility of the operator to use appropriate restraints, and
this in the interest and for the safety of the user;
•Ensure that nothing can impede the movement of the side rails (blankets, patient's
limbs, etc.) before you activate them.
•Unless otherwise medically advised by a professional, leave the side rails up and
locked while the user is sleeping or left without any supervision to avoid RISKS OF
FALLING; also, it is recommended to keep the height of the bed to its lowest in order
to reduce the RISKS OF INJURIES related to falling.
•Make sure the feets are not under the device when lowering the patient surface to its
lowest. When the siderails are open (unlock position), they may come in contact with
the ground and raise a little.

20
Angle indicators
The approximate angle of the back-rest section relative to the ground is approximately
given by the angle indicator fixed underneath the back-rest section. The measurements (in
degrees) is indicated by a small ball following the etched graduation.
Length extension of the platform
* It is recommended to elevate the foot section to the maximum in order to operate the
extension of the platform with ease.
1) Pull the cable located under the foot section;
2) With the other hand, push/pull the foot extension of the structure;
3) Release the cable. The extension will lock automatically to the following mattress
dimensions: 84 in & 88 in (213 cm & 223 cm).

4) Push the button located to the end of the foot section
5) With the other hand, push/pull the foot extension of the section
6) Release the button. The extension will lock automatically to the following
mattress dimensions: 84 in & 88 in.
WARNING ON LENGTH EXTENSION OF THE PLATFORM
▪Never extend the foot section platform without extending the foot section of the
structure to avoid MECHANICAL BREAK AND/OR INJURIES.
▪After extending the platform, always verify that the length fits the size of the
mattress use to avoid RISKS OF ENTRAPEMENT that could lead to DEATH.
