Cleaning & Disinfection
CLEANING AND DISINFECTING
Cleaning and Disinfection are two separate procedures.
For sanitary maintenance of the bed, follow the suggested recommendations of the
manufacturer(Burke) and the institution regarding cleaner/disinfectant solutions of choice
and appropriate concentrations.
Routine cleaning is to be done on a daily basis by wiping the surfaces with a disposable
cloth using warm water and a mild detergent or cleaning solution. In the event of known infec-
tion,bloodorbodyuidscontamination,cleanrst,then disinfect following facility guidelines
using disinfectants at their recommended concentrations.
Burke recommends a chlorine based solution no greater than 10,000 PPM for routine decon-
tamination.
The bed and components should also be cleaned and disinfected between patients and be-
fore returning to service after a period of storage, per facility guidelines.
UNPLUG ALL POWER CORDS BEFORE PERFORMING CLEANING
All staff performing cleaning/disinfection processes should wear appropriate personal
protective equipment (PPE)
Do Not use alkaline or acid chemical products outside of the optimal pH range or 6-9.
Do Not use any scouring or abrasive cleaners on the bed.
Do Not use caustic or corrosive substances or chemical substances which may affect the
structure of the bed, such as acetone.
Do Not hose down, use high pressure spray or steam to clean as this may cause damage
to the electronics system and void the warranty.
Always wipe down the areas cleaned with clear water after cleaning or disinfecting
All cleaning solutions must be properly diluted according to the manufacturer’s instructions.
Follow standard institutional wipe down and infection control procedures. If the facility has
aHygieneOfcerorothergoverningbodyforcleaningandinfectioncontrolconsultthemto
ensure both internal and external compliance.
Allow all surfaces to thoroughly dry, including any electrical components that could have

Troubleshooting
Problem Check the following:
Bed does not operate > Check all cords for fraying, cuts or damage and replace immediately.
> Check that the bed is plugged in, and that the wall outlet is working.
> Check for green power-on light on top of control box, this indicates AC power
to the box. If no light, and wall outlet is working, then fuses may be bad (requires
tools).
> If all or some of the relays in control box “click” when pendant is activated, and
bed does not move, replace control box.
> If no relay “click” can be heard from control box, check that pendant and other
cords are completely plugged into control box.
> If control box is found to be bad, check that no cords have been pinched or
severed. Also check that actuators and all moving parts are not obstructed.
Also check for damaged or dented actuators.
Bed only operates on battery > check that the bed is plugged in, and that the wall outlet is working.
Only a portion of the bed > Check all cords for fraying, cuts or damage and replace immediately.
operates, while others don’t
work > Check that you are applying enough pressure to the pendant button to perform
the function selected.
> Check that all plugs are securely installed into the control box and that the
control box plug clamp is in place.
> Check that travel on all actuators and other moving parts are not obstructed.
> Try a different location on control box. (ie: if head gatch does not work but
knee gatch does, plug head gatch into knee gatch outlet. If head runs, then the
problem is in control or pendant, if no function, problem is a bad actuator.
Scale System > If no display, check batteries for possible replacement need.
does not operate
(OPTIONAL) > Check that the W.I. display is plugged into the load cells, and that the connector
to each load cell (at each caster) is properly connected.
> Check that casters are properly aligned with bed and that caster brakes are set.
> Check that the cabling on any of the interconnects is not cut or crimped
causing a signal problem.
> Check that there is clearance between the top of the caster and the bottom of
the load cell housing. There must be some space between the top of
the caster bearing cover and the housing.
If none of these suggestions results in full function returning to the bed, then refer to a properly trained service
personnel for technical assistance.
WARNING: If the bed loses any function or is damaged in any way stop using the bed immediately
