SECTION 1—GENERAL GUIDELINES
WARNING
SECTION 1 - GENERAL GUIDELINES contains important information for the safe
operation and use of this product.
Contraindications
ALWAYS consult the patient’s physician before using the MA90Z and MA95Z systems.
Installation
The MA90Z and MA95Z systems MUST be installed on medical bed frames with side
rails. The side rails MUST be in the raised position whenever a patient is on the bed.
Controls on the footboard may be obstructed by the power unit on a few bed frames. It
may be necessary to relocate the power unit. Refer to Installing the Power Unit on page 11.
Check that air hoses and power cord are clear of moving bed components before placing
a patient on the bed. Operate all bed frame motorized functions through their full range
of motion to be certain that there is no pulling, interference or pinching.
DO NOT strap the mattress to the bed frame at the head and foot ends. Secure ALL
mattress straps. Secure the straps to the bed deck at the head and foot ends and to the
frame at the center of the bed. Otherwise damage to the mattress will occur when the head
and foot ends are raised. Refer to Installing the Mattress Replacement System on page 10.
Entrapment May Occur
WARNING
Patient entrapment with bed side rails may cause injury or death. Mattress MUST
fit bed frame and side rails snugly to prevent patient entrapment. Follow the
manufacturer’s instructions. Monitor patient frequently. Read and understand the
Owner’s/Operator’s Manual prior to using this equipment. Invacare product
manuals are available at www.invacare.com or your dealer.
Proper patient assessment and monitoring, and proper maintenance and use of
equipment is required to reduce the risk of entrapment. Variations in bed rail
dimensions, and mattress thickness, size or density could increase the risk of
entrapment. Visit the FDA website at http://www.fda.gov to learn about the risks of
entrapment. Review “A Guide to Bed Safety”, published by the Hospital Bed Safety
Workgroup, located at www.invacare.com. Use the link located under each bed rail
product entry to access this bed safety guide.
Refer to the owner’s manuals for beds and rails for additional product and safety
information.
After any adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely. Assist rails with dimensions different from the
original equipment supplied or specified by the bed manufacturer may not be
interchangeable and may result in entrapment or other injury.

SECTION 1—GENERAL GUIDELINES
Fire Hazard
DANGER
Smoking
DO NOT SMOKE while using this device. This system uses room air for circulation
through the mattress. A cigarette can burn a hole in the bed surface and cause
damage to the mattress. Also, patient clothing, bed sheets, etc. may be combustible
and cause a fire. Failure to observe this warning can result in severe fire, property
damage and cause physical injury or death.
Smoking by visitors in the room will contaminate the system. Therefore, visitor
smoking is NOT permitted.
Anesthesia Equipment
There is an explosion risk if used with flammable anesthetics.
Oxygen
There is a possible fire hazard when used with oxygen administering equipment
other than nasal mask or half bed tent type. The oxygen tent should NOT extend
below mattress support level.
Electrical
DANGER
Electrical shock hazard. DO NOT remove cover. Refer to qualified service
personnel.
Before performing any maintenance to the power unit, disconnect the power cord from
the wall outlet.
DO NOT insert items into any openings of the control unit. Doing so may cause fire or
electric shock by shorting the internal components
The control unit MUST be kept away from all heat sources and radiators during
operation.
Connect the equipment to properly grounded three prong wall outlet using 10‐14 ft
hospital grade power cord provided with the product.
Grounding reliability depends upon a properly grounded receptacle (3‐prong).
