Installation



WARNING

The MA90Z and MA95Z series (including bariatric) is recommended to be installed on medical bed frames with bed side or
assist rails. It is preferred that the rails be in the raised position whenever a patient is on the bed. Health care professionals
assigned to each case should make the final determination whether side or assist rails are warranted after assessing patient
risks of entrapment and falls in accordance with State patient restraint legislation or facility interpretation of such legislation.

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 16.

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 14.
