During Operation
In the case of any unusual noises or smells during operation, switch
the power off at the mains immediately. Ensure that no cables are
trapped in the mechanisim or are damaged.
7. Maintenance, Care and Warranty
To clean the powder coated tubular sections and wooden parts use a
damp cloth with normal household cleaners or warm soapy water.
Do not use any cleaning agents containing ammonia, avrasives or
strong solvents. This will lead to damage of the power-coated finish on
metal parts and the finish on the wooden parts.
Mechanical cleaning, scouring, high-pressure hoses or automated
cleaning will damage the bed.
All moving parts on this appliance are gitted with maintenance free
self-lubricating bearings and should not be oiled or greased.
All motors, cables and mechanical functions must be checked by a
suitably qualified service engineer for damage and correct operation,
at least once every twelve months.
1. Important Notice
Before putting the Warwick Bed into operation, it is very important that the user
manual is read carefully. The manual contains important information for the safe
and proper use of the bed.
Please keep this manual handy for future reference.
All of the functions of this bed should be fully tested by a competent person before
use.
The bed must not be used if faults have been detected that may injure the patient,
staff, a third person, or damage the bed or the surrounding interior.
The bed may only be used by persons who, by their knowledge, training or practical
experience, provide a guarantee that the bed will be used in a safe and correct
manner.
The operating persons are obliged to acquaint the patient lying on the bed with the
control functions that are designed for use by the patient, and their safe usage.
The operating person is obliged, before using the bed, to be confident of the
functionality and safe usage of the bed.
The bed must be used only on even and solid floors.
The bed must not be overloaded or exceed the safe working load even for a brief
period. Maximum Working Load- 180 kg (28.3 stones)
If there is a patient on the bed, the castors must be locked (with the exception of
when transporting the bed) - an unlocked bed poses a risk of injury to the patient
when leaving the bed or when supporting themselves.
The height of the mattress platform must be adjusted according to the height and
condition of the patient.
No other people may sit on the bed.
When handling the mobile parts of the bed, care must be taken that the patient,
other people or objects do not become trapped during its movement.
Before cleaning or maintaining the bed, the supply cable must be disconnected
from the mains.
The bed should not be used where there is a danger of explosion or in the presence
of inflammable anaesthetics.

6. Additional Safety Information
All persons assembling or using the bed should have read the user manual
and familiarised themselves with its operation. Ensure that objects such as
waste paper baskets, occasional tables, chairs etc. are not placed
underneath the lifting mechanism of the bed.
To avoid injury, no limbs or body parts of either the occupant or carer must be
protruding from the bed, between the side rails or in the scissor mecanism of
the bed during operation of the powered functions. Before moving the bed to
a different location, remove the electrical plug from the 230v mains supply
power socket. Failure to do so may result in damage to the bed or fatal injury.
When moving the bed with occupant in situ, the bed should not be pushed
over a threshold strip of more than 2 cm maximum height. Under no
circumstances must the bed be moved by pulling or pushing the side rails,
either when the bed is occupied or empty. They are not designed for this
purpose. Never exceed the maximum usage period of 6 minutes per hour for
the electrically driven bed functions, by lengthy and unnecessary profiling or
height adjustments. This can trip the thermal safetly fuse, which will stop all
powered movement of the bed parts.
Once the bed is sited in the desired potion, always ensure
that the castors are locked in the braked position (see
illustration)
Before dismantling or troubleshooting
Ensure that all functions are in the lowered position (where possible), the
power supply is switched off and the power cable is disconnected from the
mains by un-plugging. Ensure that all functions are not under any undue load
and are free moving.
Before Operation
Ensure that assembly is completed fully, in accordance with the user manual.
Ensure that t he local electrical mains supply voltage corresponds to that
marked on the main control unit label before connecting to the mains supply.
Ensure that cables from all motors are connected to the main control unit
correctly before operation.
When maintaining and cleaning the bed in the space between undercarriage and
mattress platform, the adjustment functions on the handset must be locked so there
is no accident due to any unintentional activation and subsequent downward
movement of the mattress platform.
The mains cable must be placed in a way so it does not get wound round the mobile
parts or trapped between them; if the mains cable is damaged there is a serious
danger of injury from electrical current.
An inspection should be made at least once a month for visible wear and tear of all
mobile parts and cables.
The bed is intended for adults from 12 years of age. Ensure that children only have
access to the bed under adequate supervision. Do not allow children underneath
the bed while it is in operation.
This modular nursing bed has four electrically powered functions - back, knee,
break and height adjustment.
2. Features
The drives for the adjustment functions consist of electrical mechanical linear
motors with maintenance free permanent lubrication.
The motors are operated by a hand controller, which is connected to the main
control unit via a spiral wound cable.
The motors and hand controller are isolated from the mains voltage (230v) and
operated at DC 24v low voltage.
3. Installation
The Warwick Bed should only be assembled by a suitably competent person.
The fuse in the electrical mains plug should not exceed 5 amps.
The bed should be located on a level flat surface.
Do not site the bed on loose carpet, rugs or floor coverings.
The cable from the mains 230v power supply plug to the main control unit must be
positioned clear of the lift mechanisim (danger of shearing or crushing) and the
braked castors.

5. Operation Instructions
5.1 Operation of height and profiling functions
The head section, knee break and bed height are adjusted by
pressing the appropriate button on the hand controller. The buttons
are lavelled according to their function. On the reverse of the hand
controller there is a clip that allows the hand controlelr to be stored on
either of the side rails or on the head/foot boards as appropriate.
Warning. Do not exceed the maximum usage period - all functions
have a maximum usage of 6 minutes per gour (10%).
5.2 Operation of the side rails
5.2.1 Raising the side rails
Hold the upper side rail and lift by moving up the slide channel until the
latch engages with an audible click. (It is advisable for safety reasons
to raise the head end first). Release the rail and it will stay in position,
as the rails are joined together the lower rail will also have been lifted
and will stay in position.
5.2.2 Lowering the side rails
Lift the upper side rail until it stops
and hold, push the spring loaded
latch release button fully in (see
diagram) and then lower the side rail
until the bottom rail rests onf the stop.
(It is advisable for safety reasons to
lower the foot end first).
Note: The side rails are automatically
spaced at all times so that the carer’s
fingers are not trapped as railers are
lowered.
4. Assembly
4.1 Assembly of bed frame
Slide the side sections together as indicated in the diagram.
Ensure both sections fit fully together until the outer tubes touch each other
and fir the securing dowels and pins on both sides of the bed frame before
tightening the thumbscrews on the under side of the bed frame. Do not over
tighten.
4.2 Assembly of bed frame to lifted chassis
Once assembled the bed frame can be fitted to the lifted chassis.
Firstly identify the “head” and “foot” ends of the lifter chassis.
The lift motor is located at the “foot” end of the lifter
chassis. There is also a roller either end of the tubular
cross member on the foot end. The “head” end has a
similar tubular cross member with rollers that is shorted
in length (note: this will only allow the unit be be
assembled the correct way around)
First unscrew the thumb screws located on the both
sides of the head section of the bed frame in the location
cups (see diagram). Unscrew leaving nothing protruding
through on the inside. Do not remove completely.
Once located slide the parallel guide-ways on either side
of the foot end of the bed frame onto the rollers at the
foot end of the lifter chassis.

At the other end of the bed, locate
the top and bottom side rails to the
assembled side rail slides, inserting
the protruding steel fingers into the
corresponding holes in the ends of
the rails. Carefully leave the other
ends of the rails resting on the floor.
Insert the steel “fingers” of the side
rail slide assembly into the holes in
the side rail slide as shown in the
diagram. Then insert the top of the
side rail slide into the aluminium
channel (painted end upwards);
inserting the nylon spacer into the channel before sliding the complete
assembly up into the channel using the upper rail until fully home and
the release button latch engages with an audible click.
Replace the retaining block in the bottom of the aluminium channel.
Screw in the thumbscrew ensuring the threaded end of the screw full
locates in the hole in the back of the aluminium channel, with the
threaded end of the screw located in the hole in the channel as
previously described.
Warning. The correct location of the threaded end of the screw into the
hole in the aluminium channel is essential to prevent the side rail slide
assembly from dropping out of the bottom of the channel when in use.
Lower the head end of the mattress support onto the tubular cross
member at the head end of the lifter chassis, ensuring the location
cups are completely seated on the ends of the tubular cross member.
Screw in completely and tighten the thumb screws. Do not over
tighten.
Using a flat blade screwdriver gently pry open the cable-retaining
strap on the main control unit located at the head end of the lifter
chassis. Locate the multi-pin plugs on the various power cables and
fully insert them in their respective sockets in the main control unit.
The plugs and sockets are labeled and should correspond like for like
when inserted. When all plufs are inserted snap the retaining strap
into position to prevent the plugs being accidentally pulled out as the
bed is used.
Warning. Ensure that all spiral wound cables are clear of the scissor
mechanism and that there is sufficient slack to enable a smooth
operation. Periodically check all cables for any damage or chafing.
4.3 Assembly of the wooden head/foot boards and side rails
Note: Please select upper side rail or bottom side rail before
assembly. (see diagram)
Orientate the head and foot boards (they are
interchangeable) with the aluminium channels facing
inwards towards the bed as per diagram. Offer up to the
threaded lugs on the bed frame ends and secure in
position using 4 off M8x25 mm dome headed screws. Do
not over tighten. At one end of the bed, loosen the
retaining thumbscrew in the retaining block located at the
bottom of the aluminium channels on both side of the
head/foot board until the retaining block slides out of the
aluminium channel. Do not remove the screw completely
from the block. Remove the pre assembled side rail slide
assembly, noting the way that the slide connector is
attached to the fingers and where the loose nylon spacer
is located. (see diagram)
