94 pro+ Surface Instruction for Use (209196 REV 8)
Maintenance
2. Make sure the life expectancy of the top cover and surface core
assembly have not been exceeded. See
“Expected Life” on page 95 for
the life expectancy of these components.
3. If the top cover has not exceeded its life expectancy, examine the
outer cover for signs of abrasion, cuts, tears, and fluid ingress.
a. If the top cover is compromised or fluid ingress is evident—
– Evaluate the top cover for additional contamination. If
contamination is localized, replace the component(s)
affected. Refer to the applicable service manual.
– If the component is not replaceable, discard and replace the
top cover.
b. Check the seams, frame attachments, foot-end flap (if applicable),
and zippers for integrity—
– If a zipper leaves a gap, check for fluid ingress (see step 3a).
4. If the surface core assembly has not exceeded its life expectancy,
examine the assembly for fluid ingress and foam delamination (you
may need to remove the fire barrier first).
a. If fluid ingress is evident (see to step 3a)—
– Examine the inside of the top cover for any signs of fluid
ingress. Areas of discoloration are a sign of fluid ingress.
b. If foam delamination is present, replace the component.
c. If a deformity is in the foam—
– Around the edges of the surface, make sure the deformity
does not compromise the fit of the surface to frame. This
may be determined by evaluating the surface to the Hospital
Bed System Dimensional and Assessment Guide to Reduce
Entrapment.

– If the deformity is on the surface, determine the amount of
deformity by laying a straight edge across the surface and
measuring the distance of the largest gap in the patient area.
Some deformation is normal as surfaces age.
– Determine if the deformation is excessive per facility
standards. Replace or repair as necessary.
