SAFETY SUMMARY

To ensure the safe installation of the On Chair Mounting Kit for the ContourU seating system,

these instructions must be followed:

GENERAL WARNINGS

DO NOT install this equipment without first reading and understanding this

instruction sheet. If you are unable to understand the Warnings, Cautions and

Instructions, contact a healthcare professional, dealer or technical personnel if

applicable before attempting to install this equipment - otherwise, injury or dam-

age may occur.

Unless otherwise noted, installation and adjustments should be made while the

wheelchair is unoccupied

INSTALLATION WARNINGS

The position of the On Chair Mounting Kit in the different mounting bracket

configurations is directly related to the chair's stability. When the On Chair

Mounting Kit is installed on a TILT and/or RECLINING wheelchair, the

wheelchair's stability may decrease. It may be necessary to reposition the FRONT

CASTERS, REAR WHEELS, BACK ANGLE, TILT-IN-SPACE, RECLINE POSI-

TION and/or SEAT DEPTH before use. Refer to appropreate wheelchair owners

manual. Use EXTREME caution when using a new seating position.

Before final tightening, ensure that the brackets will not interfere with the

opperation of the wheelchair, or be in a position to injure the patient or any

attendant.

After ANY adjustments, repair or service and BEFORE use, make sure that all

attaching hardware is tightened securely.

USER WARNINGS

Skin condition should be checked frequently after the installation of any new

seating system.

Your therapist and physician should be consulted if you have any questions regard-

ing individual limitations and needs.

Working with your therapist, physician, and rehabilitation technology supplier is

the best way to assure that the ContourU seating system choice matches your

individual needs.

As the needs of the individual become more complex, the ContourU seating

system evaluation becomes more important.

INSTALLATION OF THE ON CHAIR MOUNTING KIT

BACK MOUNTING HARDWARE (FIGURE 1)

NOTE: Refer to GENERAL and INSTALLATION WARNINGS in the SAFETY SUMMARY in this instruction

sheet.

NOTE: The wheelchair hardware consists of two (2) fixed release clamps and two (2 twist release clamps.

The wheelchair hardware must be mounted facing forward (in front of the canes) with the twist release

clamps at the top and the fixed release clamps at the bottom.

NOTE: The back mounting brackets should be placed on the back cane without interfering with other

wheelchair parts or accessories.

1. Install the four (4) L brackets to the ContourU back. Refer to INSTALLING THE BACK L

BRACKETS in this procedure of the instruction sheet.

2. Install the J brackets onto the L brackets. Refer to INSTALLING/ADJUSTING THE BACK

J BRACKETS in this instruction sheet.

3. Position the back onto the back canes in the desired location.

4. On the back cane, mark the bottom edge of the two (2) lower J brackets and the top edge

of the two (2) upper J brackets as shown in DETAIL "A" of FIGURE 1.

5. Remove the mounting screw, washer, lock washer, and internal threaded mounting screw

from one of the fixed release clamps.

IMPORTANT INFORMATION

The best way to avoid problems related to pressure sores is to understand their causes and

your role in a skin management program.

Your therapist and physician should be consulted if you have questions regarding individual

limitations and needs.

All seats and/or backs should be selected carefully. Working with your therapist, and physician

is the best way to assure that a seat choice matches your individual needs.

As the needs of the individual become more complex, the seat evaluation becomes more

important.

INSTALLATION INFORMATION:

Before you install the On Chair Mounting Kit, determine where the ContourU back cushion

must be placed in relation to the seat cushion. Find the appropriate recline angle and seat

depth, and estimate where the clamps will be mounted. Remove any obstacles on the wheel-

chair back canes and seat rails that might interfere with installation.

The adjustable mounting brackets can be placed in different configurations. It is important to

determine first where the ContourU seating system will be placed in relation to the wheelchair

frame.

To maintain the original center of gravity (CG) of the wheelchair user, the ContourU back will

normally be placed between or behind the back uprights.
