HEEL ZONE REGULATOR (UNIVERSAL AND EXPANDABLE MATTRESSES)
Heel Zone Pressure can be adjusted independently from the rest of the mattress zones, if desired. The Heel zone, which
has four air cells, can be adjusted to four different pressure settings.
To set the required pressure in the Heel Zone, turn the Heel Knob to the desired position. Match the SET NUMBER to the
metal pin at the right of the Heel knob.
FIRM (1)
= 27 ± 4 mmHg
MEDIUM FIRM (2)
= 23 ± 4 mmHg
MEDIUM SOFT (3) = 14 ± 4 mmHg
SOFT (4)
= 4 ± 2 mmHg
The pressures shown above are for a mattress at the firmest Control Unit setting. Softer settings will result in
correspondingly lower Heel Zone pressures.
SAC
Support Air Cushion (K-140)
SAC
(Optional) foot support air cushion can be used to support patient’s feet and to provide zero interface pressures in the heel
area.
UNIVERSAL MATTRESS (UM)
Mattress has ability to expand in height from 8” or 10” and length to 72”, 76”, 80” and 84” by connecting supplemental
attached air cells. The UMS Mattress is supplied as an 84” mattress. To reduce the mattress size to an 80” mattress, unzip
the air cell cover and unplug the very last air cell. This reduction process can be repeated to achieve a 76” mattress or a
72” mattress. There is no authorized reduction of the mattress size below a 72” mattress.
The Universal Mattress (UM) has a four (4) position valve located at the patient’s right, foot end of the mattress. This valve
and the associated supplemental bladders (at base of mattress) allow the UM mattress to be inflated.
(K-3UM/K-4UM labeling example, K-3oemUM/K-4oemUM not shown)
1. To inflate mattress to a 10” mattress, rotate the valve selector to position #3.
2. To inflate only the foot end of the mattress to a 10” mattress, rotate the valve selector to position #2.
3. The mattress can be used for patient transportation by rotating the valve selector to position #1.
4. Valve selector position #4 will deflate the supplemental bladders and return the mattress to an 8” mattress.
5. Disconnect / Connect up to three (3) additional air cells to achieve mattress lengths from 72” to 84”.
To deflate the Universal Mattress (UM), set the valve selector to position #4 and
pull the hose (V) from the control unit flange
connector.
