General Instructions

These instructions shall always be followed when placing the mounting set INFM7 DSK Universal on a wheelchair. To be able to connect Liberty to the wheelchair, Liberty also needs to be adjusted according to the assembly instructions that are included in the delivery of Liberty.

Warnings

⚠️ WARNING! Assembly work or changes made to the mounting set must be carried out by a trained service technician, reseller, or other person assigned by Decon.

2. Overview

This section provides an overview of the components and their placement on a wheelchair.

Components:

• A: Center pipe adapter bar
• B: Outer pipe adapter bar
• C: Clamp adapter bar
• D: Holder adapter bar
• E: QR-Pin
• F: Chassis clamp
• G: Clamp screw

ℹ️ Info: The shape and position of the chassis clamp (F) can vary depending on the tube size of the chassis and might not match the clamps in the picture above.

ℹ️ Info: The position of the assembly can vary depending on the specific wheelchair. The assembly can be made both in the upper and lower part of the wheelchair. The following instructions apply to both assembly variants.

3. Assembly Adaptor Kit

Step 1: Assemble the holder adapter bar (D) inside the chassis clamps (F) using the clamp screws (G) onto the chassis of the wheelchair. Tighten the clamp screws (G) just enough to grip the wheelchair chassis so that the chassis clamps (F) can still be adjusted along the chassis. Assemble both sides.

If the chassis clamps (F) are assembled in the upper part of the wheelchair underneath the seating, then distance X from the edge of the seating cushion to the holder (D) should be, if possible, 20mm.

ℹ️ Info: In some cases, it can be preferable to remove the original brakes of the wheelchair to make room for assembly of the adaptor bar. On some chairs, it might also be needed to loosen the seat cloth a little bit to make room for the chassis clamps (F).

Step 2: Mount the complete adapter bar, consisting of center pipe (A), outer pipe (B), and clamp (C). The complete adapter bar is mounted into the holders (D) by using the QR-pins (E). Make sure the ends of the outer pipe (B) are parallel; otherwise, it can be hard to assemble it into the holders (D). It shall be possible to move the center pipe sideways and also rotate it if correctly assembled.

Step 3: Adjust both of the chassis clamps (F) so that the outer surface is placed vertically related to the surface of the ground. Tighten the screws (G) in both of the clamps (F).

ℹ️ Info: Check that the arrow on the labeling mounted on the center pipe (A) is pointing towards the front of the wheelchair. If the center pipe (A) is mounted the wrong way around, it will not be possible to attach Liberty to the bar.

⚠️ WARNING! The screws (G) holding the clamps (F) must be tightened to 20-24Nm of torque. Loctite 243 or equivalent shall be applied to the screw before it is assembled.

4. Adjustment of the Adaptor Bar

Use the leveling tool that is included in the delivery of Infinity. Since the adapter bar has splines inside, it will not be possible to get the bubble of the spirit level exactly right. Just choose the most correct position.

The leveling tool has two marks, "H" and "L". When the bubble of the spirit level is towards "H", the castors of the wheelchair will lift higher from the ground compared to if the bubble of the spirit level is towards "L".

Adjustment of the angle can be done in two different ways. Both are described below.

Alt1.

Using the adjustment tool that is included in the delivery of Infinity (not this mounting set), set the angle of the adaptor bar so that the level tool is in level. Inside the pipes, there are splines, so when rotating, you will feel and hear a clicking. When the desired angle has been accomplished, check that the center pipe is centered in the wheelchair. Now tighten the screws in the clamps (C).

⚠️ WARNING! The screws holding the clamps (C) shall be tightened to 7-9Nm of torque.

Alt.2

Using the adjustment tool that is included in the delivery of Infinity (not this mounting set), set the angle of the adaptor bar. Only mount the inner pipe on one side and then rotate the center pipe to the correct angle. Now mount the other inner pipe in the same position/angle as the first one. Check that the center pipe is centered in the wheelchair. Now tighten the screws in the clamps (C).

⚠️ WARNING! The screws holding the clamps (C) shall be tightened to 7-9Nm of torque.

ℹ️ Info: Don't forget to reassemble the brakes of the wheelchair in case these were removed when mounting the adaptor. Also, if the seat cloth was loosened during mounting of the adaptor, don't forget to reassemble this.

Now read the assembly instructions that were included in the delivery of the Infinity unit. Assemble and adjust the Infinity according to the instruction.
