Harmar’s Curved Stair Lift is easy to install. The standard installation
will normally take two installers approximately three hours. The time
will vary depending on the complexity of the lift ordered and custom
designs.
1. Review Installation Drawing The dimensions on the drawing
show numbers on the stairs. These numbers indicate the position
of the supports.
2. Carry chair/chassis to the location of the installation. Usually
top of stairs. It's best to be a at section of rail.
3. Position Stair Supports Place on the stair based on the
installation drawing but do not bolt anything down at this point.
[Figure 5-1]
4. Assemble the Rail Place the rail in the correct position beginning
with the rst section downstairs. Unwrap the rail, checking the
label for order of placement on stairs. [Figures 5-2, 5-3]
Follow the drawing included with the rail system.
Run a wire through the lower rail. There is a hole at the charger
location for it to come out. [Figure 5-4]
5. Check both ends of the rail and wipe clean. You may need to
clean the ends with Emery paper and add a small amount of
grease to help slide the pipes together. [Figure 5-5]
Figure 5-1
WIRING NOTE: You may complete the wiring while putting
the rail together or use a sh tape on the completed unit
to run the wire.
IMPORTANT - Do NOT lay chair on its back.

6. Slide the pipes together one at a time starting at the bottom in the order indicated on the label. Install
on the stair supports. [Figures 6-1, 6-2, 6-3]
A ratcheting strap can be used to help pull the rails together.
7. Connect parts at the joint with the supplied bolts. Carefully tighten as you assemble the rail
[Figures 6-4, 6-5]
When you arrive upstairs, adjust the position of the rail and supports while you compare with the
drawing.
8. Rail Leveling/Alignment: Using the angle meter, set the rail to the correct angles and check the
drawing to verify that all clearances are correct.
DO NOT tighten all the leg set screws yet, only set enough to support the rail. Leave the others oating.
INSTALLATION
NOTE: When installing to stair,
ensure the hardware is long
enough. If the carpet is very
thick, it might require longer
hardware.
NOTE: Watch for tack strips.
Avoid mounting on them. If
you can't avoid them, shims
will be required.
CHECK
TEST RUN - Prior to bolting down the supports, install the chassis and run it on the rail to
check all clearances. It may be necessary to bolt down one or two legs to hold the rail in place.
If necessary, move the rail position to provide the best t

10. Chassis Load
Roller position-Ensure charging point [Figure 8-5] is on the top.
Using the loading bar, [Figure 8-6] slide on until drive hits the gear rack.
Activate the rocker [Figure 8-7] to drive onto rack, watching the wheels to ensure they go on smoothly.
Ensure the unit goes down the gear rack about 6".

11. Replace Shroud and install load switch cover on back.
Test run chassis to ensure all the clearances are ok. Move rail as needed to make the best t. If
installing mid-charging location locate it now.
Installing Mid-Charge Locations
1) Locate Chassis to where the midstation park should be on the rail. [Figures 9-1, 9-2]
2) Mount to the rail using self taping screws provided [Figures 9-3, 9-4]
3) Align charge feet to chassis, ensure the charge feet are compressing about 1/4". [Figures 9-5, 9-6, 9-7]
4) Drill the hole in the rack to pull
wire out. [Figure 9-8]
5) Connect wire to charge station,
ensure the red wire matches the
location of the red wire on the
chassis. [Figure 9-9]
6) Install Cover

12. Supports: Re-check angles, then, using the appropriate hardware, attach the supports to the stairs,
starting at a corner. Firmly set the supports to the rail with set screw. Repeat the process at the other
corners; re-check angles. Complete all other legs. [Figures 10-1, 10-2]
13. Charging Station
Install charging station on rail. [Figure 10-3] Top and bottom. Align with chassis [Figure 10-4]
Alignment
Align charging stations. Pay attention to the
charging contacts where the drive unit meets
the station. They should apply pressure to the
charging strips on the chassis. Adjust as needed.
The spring loaded contacts should compress
about 1/4 of an inch. [Figures 10-5, 10-6]
Route red and black wires through hole provided
in rail by charging station. Use provided gromnet
to protect wire.
Determine which end has the AC power for the
power supply. Connect the power supply with
the provided connector which has a red and
black wire, to the red and black wires. Using the
provided terminals attach the charge wire to the
wires in the rail. [Figure 10-7]
NOTE: The power supply charger needs to be placed out of the weather elements to be protected.
INSTALLATION
NOTE: When on carpet tighten down the oating legs rst, then tighten the set screw on them.
Loosen the set screws on the legs you were using for support and tighten them to the oor. Tighten
the set screw.

Final Checks
Before putting the lift into operation for the user verify the following:
• Check all stops (top, middle & bottom)
• Foot rest (Both direction of travel)
• Rail obstruction-both directions
• Rail (all hardware and mounting hardware are tight)
• Final limit (both ends of travel)
• Seat swivel (lift won't run if seat is swiveled)
• Check all clearances to ensure there are no pinch points
• Provide the Owner’s Manual and review the lift’s operation and stops with the customer.
• Charge for 12 hours after testing is complete.
• Test wireless remote (in both direction of travel)
• Seat postion, level at top and bottom. If it is not level or customer would like the chair to have a slight
uphill tilt, adjust with the leveling joint.
- Loosen set screw (2.5 mm)
- Remove screw (6mm)
- Adjust joint in or out depending on which direction you want the chair to go
