Installation Instructions

Tools Required:

| Phillips Screwdriver
(or other tool(s) as needed to remove wheelchair sling seat)| | 10mm Wrench and
Long-nose Pliers used for Anti-rollback Installation
---|---|---|---
| 2x 7/16″ Wrenches
or Socket Wrenches used to adjust mounting bars| | 3/16″ Allen Wrench
used to adjust upper lift force

STEP 1 – Review For Compatibility Before Installation
Review chair for compatibility with lift seat and anti-rollback devices. See the Warnings, Compatibility, and Installation sections of this manual and the anti-rollback device manual before beginning installation.
STEP 2 – Remove Wheelchair Sling Seat and Armrests
a. Remove your wheelchair’s sling seat. Most standard folding wheelchairs’ sling seats are attached with 8 to 10 screws which can be removed using a phillips screwdriver. (figure 1)
b. Retain the seat and screws in a safe location.
c. Remove your wheelchair’s armrests. The armrests will remain on the chair after installation but should be removed to provide better access to the seat- mounting tubes during installation. (figure 2) STEP 3 – Install Lift Mechanism
a. Using (2) 7/16 inch wrenches, loosen the mounting bar width-adjustment bolts to allow the bars to slide in and out. Do not completely remove the bolts. (figure 3)
b. Adjust the mounting bars to the approximate width of your wheelchair’s mounting tubes.
c. Set the lift mechanism onto the wheelchair.
The mounting hooks should fit securely over the wheelchair’s seat tubes as shown. (figure 4)
d. Ensure that the lift mechanism is centered between the two seat tubes and that the rear hooks are positioned next to the backrest vertical tube.
e. Using (2) 7/16 inch wrenches, tighten the mounting bar width-adjustment bolts. (figure 5)
f. Tighten four thumb screws to secure the mounting hooks to the wheelchair’s seat tubes. (figure 6) STEP 3a – Install Lift Mechanism (Optional seat height adjustment for some installations)
Follow these directions if your lift seat mechanism is interfering with the cross bars on your wheelchair and additional clearance height is needed. Always verify that a higher seating height is appropriate for the user before placing the wheelchair into use.
Note that this operation will increase the wheelchair’s seating height and will also require a higher bumper mounting height for the anti-rollback device.
a. Remove the lift seat mechanism from the wheelchair and set on a work surface.
b. Using a 1/2 inch wrench, remove the two bolts connecting the mounting hook to the adjustable slide bar. (figure 7)
c. Adjust the hook to the low, middle, or high position:
Lowest Hook Height = Higher seat height and more clearance (figure 8)
Highest Hook Height = Lower seat height and less clearance (figure 9)
d. Rethread both bolts and tighten snugly using a 1/2 inch wrench.
e. Check the fit on your wheelchair and readjust using Steps 1-4 if necessary.
f. Complete all steps listed in Step 3 of this manual before proceeding.
WARNING: All four of the seat’s hooks must be set to the same height to ensure correct function. STEP 4 – Install and Test Anti-Rollback System
a. Locate Direct Supply® Anti-rollback Device and owner’s manual, included.
b. Read entire owner’s manual and then install antirollback device. (figure 10)
c. NOTE: During Step 6 – Adjust Seat Bumper Height (page 10 of the Anti- rollback Device manual), set the anti-rollback device’s bumper height so that the top of the bumper is about one inch above the bottom of the plastic lift seat when the seat is fully collapsed (down position).
If your installation requires additional bumper height, which may occur when using the lowest hook height setting (see step 3a), you may use the included wooden spacers to increase the height of your anti-rollback bumpers. Remove the foam bumpers, insert the wooden spacers into the bumper cavities, and replace the bumpers before continuing installation. d. Before proceeding to the next step, test the anti-rollback system to ensure functionality according to the instructions on page 13 of the Anti-rollback Device owner’s manual. Instead of sitting in the wheelchair’s sling seat to test the system as instructed in the owner’s manual, compress the lift seat mechanism and ensure that the anti-rollback system is correctly activating and deactivating as the seat is raised and lowered. (figures 11a and 11b) STEP 5 – Attach Wheelchair User’s Seat Cushion
Locate user’s seat cushion
WARNING: If the wheelchair user does not have a seat cushion or if the cushion does not fit onto the lift seat device, do not continue the installation or use this device. Do not allow a user to sit directly on the lift seat’s plastic seat pan. Contact your Direct Supply Account Manager if you need to purchase a pressure-redistributing seat cushion.
a. Clean the bottom of the cushion with an alcohol prep pad, disinfecting wipe, or other quickdrying cleaner to ensure that the hook-and-loop strips adhere to the cushion’s bottom cover.
b. Peel the protective backing from the loop side of the cushion-attachment strips, which are pre-installed onto the top of the lift mechanism’s plastic seat. (figure 12)
c. Carefully position the cushion onto the plastic lift seat so that the exposed adhesive strips attach to the cushion’s bottom cover. Ensure that the cushion is centered left-to-right and that the front edge of the cushion aligns with the front edge of the lift seat. You may wish to allow the front edge of the cushion to slightly overhang the plastic lift seat to prevent the wheelchair user’s legs from contacting the hard plastic edge. Press firmly onto the cushion to adhere to the attachment strips. (figure 13)
d. Route the cushion’s rear strap through the provided slots at the back of the plastic lift seat. Secure the strap and any extra loose strap material, being sure to avoid allowing the strap or excess material to interfere with the lift mechanism. (figure 14)
e. Sit on the cushion, allowing the lift seat mechanism to move up and down as intended. Ensure that the cushion is secured and cannot slip forward during use. Do not use lift seat if the cushion is not secure or if the cushion interferes with the lift seat’s use.
ENSURE THAT CUSHION IS SECURE AND DOES NOT SLIDE, TIP, OR INTERFERE WITH LIFT MECHANISM BEFORE PROCEEDING STEP 6 – Install Rear Cover
a. Press the hook-and-loop strip on the rear cover onto the compatible strip on the rear of the plastic seat. (figure 15)
b. Fit upper attachment loops over the wheelchair’s push handles, as shown. This is easiest if the lift seat is in the “up” position. (figure 16)
c. Adjust slides so that the loops fit loosely over the wheelchair’s handles when the lift seat is in the “up” position. (figure 17)
d. Test the fit of the rear cover by moving the lift seat up and down a few times, ensuring that the cover is securely in place throughout the seat’s travel range.![DIRECT SUPPLY 2TB2Y EZ Lift Wheelchair Seat with Anti Rollback

• parts6](https://manuals.plus/wp-content/uploads/2024/03/DIRECT-SUPPLY-2TB2Y- EZ-Lift-Wheelchair-Seat-with-Anti-Rollback-parts6.jpg) STEP 7 – Prepare the Wheelchair for Use
  a. Reinstall removable armrests and ensure that seat system functions without interference.
  b. Reinstall removable footrests, if applicable.
  STEP 8 – Test all Functions Before Use
  a. Test the lift seat functionality.
  a.1 Manually compress the lift seat to ensure stability, range of travel, and to check for interference with the wheelchair or any installed accessories.
  a.2 Ensure that both covers are installed before use.
  a.3 Check the cushion’s attachment to the plastic lift seat to ensure a secure connection and correct positioning.
  b. Test the anti-rollback functionality
  b.1 With the wheelchair empty and the lift seat in the “up” position, confirm that both brake bars are level and resting on the wheelchair’s rear wheels.
  b.2 Push the chair firmly backwards to verify the system is preventing rearward movement.
  b.3 Sit in the wheelchair in a natural seating position and verify that the chair can roll freely forward and backward.
  b.4 Stand up from the chair while pushing backwards on the chair, verify that the anti-rollback system engages.
  b.5 Refer to the Anti-rollback Device’s user manual to make adjustments to the anti-rollback device, if needed.
  c. Re-test the system with the primary user of the wheelchair.
  c.1 You may need to adjust the counterbalance bar depth, seat bumper height, and/or the spring force to accommodate individual users’ weight and/or seating position.
  c.2 See the Directions for Use section (pages 11-14) of this manual for instructions about how to adjust the force settings.
  WARNING: Do not use the device or the wheelchair if the system is not functioning as intended.

Directions for Use

Directions for Use
Your Direct Supply EZ-LiftTM Wheelchair Lift Seat Device is designed to provide between 20-60 lbs of lift assistance while standing. The system should help enable a resident who is otherwise able to stand and ambulate safely, however the lift seat is not expected to fully lift the resident by itself.
Adjusting Primary Force Setting
Follow these steps to adjust the primary force adjustment setting. For fine- adjustment of seat collapse force, see the next step. These steps must be done with the assistance of the wheelchair user in order to ensure proper adjustment and function of the device.
WARNING: Do not attempt to adjust force while the wheelchair or lift seat is occupied.
a. Access the force adjustment by removing the bottom strap of the front cover, as shown. (figure 18)
b. Remove hairpin from the round pin and then remove the round pin so that the adjustment lock swings freely. (figures 19a and 19b)c. Lift gently on the back of the plastic lift seat and then guide the adjustment block into one of the desired force settings, as shown. (figure 20)
d. Once the desired force setting has been selected, swing the adjustment lock into its home position and secure with round pin and hairpin. Replace front cover strap before using chair. (figures 21a and 21b)
e. Allow the user of the wheelchair to test the seat force. Ensure that the seat is providing stability while sitting and force assistance while standing. If necessary, make adjustments to the force setting based on user’s preference. Fine-adjustment of seat collapse force may be made in the following step, if desired. Adjusting Rear Lock Lever
Your seat lift includes a rear lock lever which holds the seat in flat position if the lift seat functionality is not desired, or if the chair must be moved backwards while empty. The system is also designed so that the lift force when the seat is fully flat is less than 10 lbs (which ramps up to the higher force as the seat lifts). This means that a resident can sit in the seat without needing to activate/deactivate the rear seat lock lever. The seat will automatically lift when standing and can be left in the up position until the resident sits.
Move the lever to the “up” position to allow the seat lift to raise and lower. To lock the seat in the flat position, push the seat down and then push the rear lock lever to the “down” position. (figure 22) Removing Lift Seat
Your EZ-LiftTMWheelchair Lift Seat may be removed from the wheelchair for cleaning or transportation. Slip the rear cover’s loops off of the wheelchair push handles, then loosen four thumb screws in order to lift the seat lift mechanism off of the chair.
When the EZ-Lift Wheelchair Lift Seat is removed, the Direct Supply seat lift device is designed to allow a wheelchair to fold even when the device is installed. Your wheelchair’s collapsed width may be slightly wider when using this device.
CAUTION! Do not force a wheelchair to a narrower collapsed position when this device is installed.
Doing so may damage your device and prevent it from functioning correctly.
Your Direct Supply EZ-Lift Wheelchair Lift Seat Device must be configured specifically for each individual combination of wheelchair, user, and any accessories such as cushions or positioning aids. The system must be checked for correct operation whenever the wheelchair height is adjusted, when there is a change to cushions or positioners, or if a new user is using the wheelchair.
Adjusting Seat Collapse Force Setting
Follow these steps for fine-adjustment of seat collapse force. Use this setting if the wheelchair user requires a lower force to lower the seat while sitting, while maintaining a higher lifting force while standing. Primary lift force adjustment should be done using the main lift force adjustment described in the previous step.
WARNING: Do not attempt to adjust force while the wheelchair or lift seat is occupied.
a. Access the collapse force adjustment by removing the bottom strap of the front cover, as shown. (figure 23)
b. Adjust seat collapse force by using a 3/16 inch hex wrench to turn the counterbalance adjustment screw to the desired position. The screw may be set at any position, as desired. (figure 24)
Turn screw CLOCKWISE Screw is fully inserted = HIGHER force to start to collapse seat
Turn screw COUNTER-CLOCKWISE Screw is backed-out = LOWER force to start to collapse seat
WARNING: Do not force screw past its maximum settings in either direction.
c. Once the desired force setting has been selected, replace the front cover lower strap.
d. Allow the user of the wheelchair to test the seat force. Ensure that the seat is providing stability while sitting and force assistance while standing. If necessary, make adjustments to the force setting based on user’s preference.
